7. Functional description
7.1 ARM Cortex-M0 processor
The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high performance and very low power consumption.
7.2 On-chip flash program memory
The LPC1111/12/13/14 contain 32 kB (LPC1114), 24 kB (LPC1113), 16 kB (LPC1112), or 8 kB (LPC1111) of on-chip flash memory.
7.3 On-chip SRAM
The LPC1111/12/13/14 contain a total of 8 kB, 4 kB, or 2 kB on-chip static RAM memory.
7.4 Memory map
The LPC1111/12/13/14 incorporates several distinct memory regions, shown in the following figures. Figure 5 shows the overall map of the entire address space from the user program viewpoint following reset. The interrupt vector area supports address remapping. The AHB peripheral area is 2 megabyte in size, and is divided to allow for up to 128 peripherals. The APB peripheral area is 512 kB in size and is divided to allow for up to 32 peripherals. Each peripheral of either type is allocated 16 kilobytes of space. This allows simplifying the address decoding for each peripheral.

LPC1111/12/13/14
32-bit ARM Cortex-M0 microcontroller
* In the LPC1111/12/13/14, the NVIC supports 32 vectored interrupts including up to 13
inputs to the start logic from individual GPIO pins.
* Four programmable interrupt priority levels, with hardware priority level masking. * Relocatable vector table. * Software interrupt generation.
7.5.2 Interrupt sources
Each peripheral device has one interrupt line connected to the NVIC but may have several interrupt flags. Individual interrupt flags may also represent more than one interrupt source. Any GPIO pin (total of up to 42 pins) regardless of the selected function, can be programmed to generate an interrupt on a level, or rising edge or falling edge, or both.
7.6 IOCONFIG block
The IOCONFIG block allows selected pins of the microcontroller to have more than one function. Configuration registers control the multiplexers to allow connection between the pin and the on-chip peripherals. Peripherals should be connected to the appropriate pins prior to being activated and prior to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is not mapped to a related pin should be considered undefined.
7.7 Fast general purpose parallel I/O
Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Multiple outputs can be set or cleared in one write operation. LPC1111/12/13/14 use accelerated GPIO functions:
* GPIO registers are a dedicated AHB peripheral so that the fastest possible I/O timing
can be achieved.
* Entire port value can be written in one instruction.
Additionally, any GPIO pin (total of up to 42 pins) providing a digital function can be programmed to generate an interrupt on a level, a rising or falling edge, or both.
7.7.1 Features
* Bit level port registers allow a single instruction to set or clear any number of bits in
one write operation.
* Direction control of individual bits. * All I/O default to inputs with pull-ups enabled after reset. * Pull-up/pull-down resistor configuration can be programmed through the IOCONFIG
block for each GPIO pin.

The LPC1111/12/13/14 contain two SPI controllers on the LQFP48/PLCC44 packages and one SPI controller on the HVQFN33 packages (SPI0). Both SPI controllers support SSP features. The SPI controller is capable of operation on a SSP, 4-wire SSI, or Microwire bus. It can interact with multiple masters and slaves on the bus. Only a single master and a single slave can communicate on the bus during a given data transfer. The SPI supports full duplex transfers, with frames of 4 bits to 16 bits of data flowing from the master to the slave and from the slave to the master. In practice, often only one of these data flows carries meaningful data.

7.15 Clocking and power control
7.15.1 Crystal oscillators
The LPC1111/12/13/14 include three independent oscillators. These are the system oscillator, the Internal RC oscillator (IRC), and the Watchdog oscillator. Each oscillator can be used for more than one purpose as required in a particular application. Following reset, the LPC1111/12/13/14 will operate from the Internal RC oscillator until switched by software. This allows systems to operate without any external crystal and the bootloader code to operate at a known frequency. See Figure 6 for an overview of the LPC1111/12/13/14 clock generation.

LPC1111/12/13/14
32-bit ARM Cortex-M0 microcontroller
Upon power-up or any chip reset, the LPC1111/12/13/14 use the IRC as the clock source. Software may later switch to one of the other available clock sources. 7.15.1.2 System oscillator The system oscillator can be used as the clock source for the CPU, with or without using the PLL. The system oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. 7.15.1.3 Watchdog oscillator The watchdog oscillator can be used as a clock source that directly drives the CPU, the watchdog timer, or the CLKOUT pin. The watchdog oscillator nominal frequency is programmable between 7.8 kHz and 1.7 MHz. The frequency spread over processing and temperature is 40 %.
7.15.2 System PLL
The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156 MHz to 320 MHz, so there is an additional divider in the loop to keep the CCO within its frequency range while the PLL is providing the desired output frequency. The output divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip reset and may be enabled by software. The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is 100 s.
7.15.3 Clock output
The LPC1111/12/13/14 features a clock output function that routes the IRC oscillator, the system oscillator, the watchdog oscillator, or the main clock to an output pin.
7.15.4 Wake-up process
The LPC1111/12/13/14 begin operation at power-up and when awakened from Deep power-down mode by using the 12 MHz IRC oscillator as the clock source. This allows chip operation to resume quickly. If the system oscillator or the PLL is needed by the application, software will need to enable these features and wait for them to stabilize before they are used as a clock source.
7.15.5 Power control
The LPC1111/12/13/14 support a variety of power control features. There are three special modes of processor power reduction: Sleep mode, Deep-sleep mode, and Deep power-down mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, a register is provided for shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Selected peripherals have their own clock divider which provides even better power control.

7.15.5.1
Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core. In Sleep mode, execution of instructions is suspended until either a reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses.
7.15.5.2
Deep-sleep mode In Deep-sleep mode, the chip is in Sleep mode, and in addition analog blocks can be shut down for increased power savings. The user can configure the Deep-sleep mode to a large extent, selecting any of the oscillators, the PLL, BOD, the ADC, and the flash to be shut down or remain powered during Deep-sleep mode. The user can also select which of the oscillators and analog blocks will be powered up after the chip exits from Deep-sleep mode. The GPIO pins (up to 15 pins total) serve as external wake-up pins to a dedicated start logic to wake up the chip from Deep-sleep mode. The timing of the wake-up process from Deep-sleep mode depends on which blocks are selected to be powered down during deep-sleep. For lowest power consumption, the clock source should be switched to IRC before entering Deep-sleep mode, all oscillators and the PLL should be turned off during deep-sleep, and the IRC should be selected as clock source when the chip wakes up from deep-sleep. The IRC can be switched on and off glitch-free and provides a clean clock signal after start-up. If power consumption is not a concern, any of the oscillators and/or the PLL can be left running in Deep-sleep mode to obtain short wake-up times when waking up from deep-sleep.
7.15.5.3
Deep power-down mode In Deep power-down mode, power is shut off to the entire chip with the exception of the WAKEUP pin. The LPC1111/12/13/14 can wake up from Deep power-down mode via the WAKEUP pin.
7.16 System control
7.16.1 Reset
Reset has four sources on the LPC1111/12/13/14: the RESET pin, the Watchdog reset, power-on reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input pin. Assertion of chip reset by any source, once the operating voltage attains a usable level, starts the IRC and initializes the flash controller. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values.

7.16.2 Brownout detection
The LPC1111/12/13/14 includes four levels for monitoring the voltage on the VDD pin. If this voltage falls below one of the four selected levels, the BOD asserts an interrupt signal to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the signal by reading a dedicated status register. Four additional threshold levels can be selected to cause a forced reset of the chip.
7.16.3 Code security (Code Read Protection - CRP)
This feature of the LPC1111/12/13/14 allows user to enable different levels of security in the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD) and In-System Programming (ISP) can be restricted. When needed, CRP is invoked by programming a specific pattern into a dedicated flash location. IAP commands are not affected by the CRP. In addition, ISP entry via the PIO0_1 pin can be disabled without enabling CRP. For details see the LPC111x user manual. There are three levels of Code Read Protection: 1. CRP1 disables access to the chip via the SWD and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors can not be erased. 2. CRP2 disables access to the chip via the SWD and only allows full flash erase and update using a reduced set of the ISP commands. 3. Running an application with level CRP3 selected fully disables any access to the chip via the SWD pins and the ISP. This mode effectively disables ISP override using PIO0_1 pin, too. It is up to the user's application to provide (if needed) flash update mechanism using IAP calls or call reinvoke ISP command to enable flash update via the UART.
CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device.
In addition to the three CRP levels, sampling of pin PIO0_1 for valid user code can be disabled. For details see the LPC111x user manual.
7.16.4 APB interface
The APB peripherals are located on one APB bus.
7.16.5 AHBLite
The AHBLite connects the CPU bus of the ARM Cortex-M0 to the flash memory, the main static RAM, and the Boot ROM.

The ADC is monotonic, there are no missing codes. The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 7. The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after appropriate adjustment of gain and offset errors. See Figure 7. The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the ideal curve. See Figure 7. The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset error, and the straight line which fits the ideal transfer curve. See Figure 7. The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated ADC and the ideal transfer curve. See Figure 7. Tamb = 25 C; maximum sampling frequency fs = 4.5 MHz and analog input capacitance Cia = 1 pF. Input resistance Ri depends on the sampling frequency fs: Ri = 1 / (fs x Cia).

The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or tVD;ACK by a transition time (see UM10204). This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge.
[7] [8]
[9]
[10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time.

11. Application information
11.1 ADC usage notes
The following guidelines show how to increase the performance of the ADC in a noisy environment beyond the ADC specifications listed in Table 8:
* The ADC input trace must be short and as close as possible to the LPC1111/12/13/14
chip.
* The ADC input traces must be shielded from fast switching digital signals and noisy
power supply lines.
* Because the ADC and the digital core share the same power supply, the power supply
line must be adequately filtered.
* To improve the ADC performance in a very noisy environment, put the device in Sleep
mode during the ADC conversion.
11.2 XTAL input
The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV(RMS) is needed.

Ci 100 pF Cg

Fig 24. Slave mode operation of the on-chip oscillator
In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 24), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected. External components and models used in oscillation mode are shown in Figure 25 and in Table 17 and Table 18. Since the feedback resistance is integrated on chip, only a crystal and the capacitances CX1 and CX2 need to be connected externally in case of fundamental mode oscillation (the fundamental frequency is represented by L, CL and RS). Capacitance CP in Figure 25 represents the parallel package capacitance and should not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal manufacturer (see Table 17).

11.3 XTAL Printed Circuit Board (PCB) layout guidelines
The crystal should be connected on the PCB as close as possible to the oscillator input and output pins of the chip. Take care that the load capacitors Cx1, Cx2, and Cx3 in case of third overtone crystal usage have a common ground plane. The external components must also be connected to the ground plain. Loops must be made as small as possible in

order to keep the noise coupled in via the PCB as small as possible. Also parasitics should stay as small as possible. Values of Cx1 and Cx2 should be chosen smaller accordingly to the increase in parasitics of the PCB layout.
