Package choice: reduced pin-count TQFP100 or feature-rich 144-pin TQFP or LFBGA The STR73xF family is available in 3 packages. The TQFP144 and LFBGA144 versions have the full set of all features. The 100-pin version has fewer timers, I/Os and ADC channels. Refer to the Device Summary on Page 1 for a comparison of the I/Os available on each package. The family includes versions with and without CAN. High speed Flash memory The Flash program memory is organized in 32-bit wide memory cells which can be used for storing both code and data constants. It is accessed by CPU with zero wait states @ 36 MHz. The STR7 embedded Flash memory can be programmed using in-circuit programming or in-application programming. The Flash memory endurance is 10K write/erase cycles and the data retention is 20 years @ 85 C. IAP (in-application programming): IAP is the ability to re-program the Flash memory of a microcontroller while the user program is running. ICP (in-circuit programming): ICP is the ability to program the Flash memory of a microcontroller using JTAG protocol while the device is mounted on the user application board. The Flash memory can be protected against different types of unwanted access (read/write/erase). There are two types of protection:

Sector write protection Flash debug protection (locks JTAG access)
Flexible power management To minimize power consumption, you can program the STR73xF to switch to SLOW, WFI LPWFI, STOP or HALT modes depending on the current system activity in the application.

Overview Flexible clock control
STR73xFxx
Two clock sources are used to drive the microcontroller, a main clock driven by an external crystal or ceramic resonator and an internal backup RC oscillator that operates at 2 MHz or 32 kHz. The embedded PLL can be configured to generate an internal system clock of up to 36 MHz. The PLL output frequency can be programmed using a wide selection of multipliers and dividers. Voltage regulators The STR73xF requires an external 4.5 to 5.5 V power supply. There are two internal Voltage Regulators for generating the 1.8 V power supply needed by the core and peripherals. The main VR is switched off and the Low Power VR switched on when the application puts the STR73xF in Low Power Wait for Interrupt (LPWFI) mode. Low voltage detectors The voltage regulator and Flash modules each have an embedded LVD that monitors the internal 1.8 V supply. If the voltage drops below a certain threshold, the LVD will reset the STR73xF. Note: An external power-on reset must be provided ensure the microcontroller starts-up correctly.
2.1
On-chip peripherals
CAN interfaces The three CAN modules are compliant with the CAN specification V2.0 part B (active). The bit rate can be programmed up to 1 MBaud. These are not available in the STR735 and STR736. DMA 4 DMA controllers, each with 4 data streams manage memory to memory, peripheral to peripheral, peripheral to memory and memory to peripheral transfers. The DMA requests are connected to TIM timers, BSPI0, BSPI1, BSPI2 and ADC. One of the streams can be configured to be triggered by a software request, independently from any peripheral activity. 16-bit timers (TIM) Each of the ten timers (six in 100-pin devices) have a 16-bit free-running counter with 7-bit prescaler, up to two input capture/output compare functions, a pulse counter function, and a PWM channel with selectable frequency. This provides a total of 16 independent PWMs (12 in 100-pin devices) when added with the PWM modules (see next paragraph). PWM modules (PWM) The six 16-bit PWM modules have independently programmable periods and duty-cycles, with 5+3 bit prescaler factor. Timebase timers (TB) The three 16-bit timebase timers with 8-bit prescaler for general purpose time triggering operations. Real-time clock (RTC) The RTC provides a set of continuously running counters driven by separate clock signal derived from the main oscillator. The RTC can be used as a general timebase or

Overview clock/calendar/alarm function. When the STR73xF is in LPWFI mode the RTC keeps running, powered by the low power voltage regulator. UARTs The 4 UARTs allow full duplex, asynchronous, communications with external devices with independently programmable TX and RX baud rates up to 625 Kbaud. Buffered serial peripheral interfaces (BSPI) Each of the three BSPIs allow full duplex, synchronous communications with external devices, master or slave communication at up to 6 Mb/s in master mode and up to 4.5 Mb/s in slave mode (@36 MHz system clock). I2C interfaces The two I2C Interfaces provide multi-master and slave functions, support normal and fast I2C mode (400 kHz) and 7 or 10-bit addressing modes. A/D converter The 10-bit analog to digital converter, converts up to 16 channels in single-shot or continuous conversion modes (12 channels in 100-pin devices). The minimum conversion time is 3 s. Watchdog The 16-bit watchdog timer protects the application against hardware or software failures and ensures recovery by generating a reset. I/O ports Up to 112 I/O ports (72 in 100-pin devices) are programmable as general purpose input/output or alternate function. External interrupts and wake-up lines 16 external interrupts lines are available for application use. In addition, up to 32 external Wake-up lines (18 in 100-pin devices) can be used as general purpose interrupts or to wake-up the application from STOP mode.

Memory mapping
Figure 5 shows the various memory configurations of the STR73xF system. The system memory map (from 0x0000_0000 to 0xFFFF_FFFF) is shown on the left part of the figure, the right part shows maps of the Flash and APB areas. For flexibility the Flash or RAM addresses can be aliased to Block 0 addresses using the remapping feature Most reserved memory spaces (gray shaded areas in Figure 5) are protected from access by the user code. When an access this memory space is attempted, an ABORT signal is generated. Depending on the type of access, the ARM processor will enter "prefetch abort" state (Exception vector 0x0000_000C) or "data abort" state (Exception vector 0x0000_0010). It is up to the application software to manage these abort exceptions. Figure 5.

Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst conditions of ambient temperature, supply voltage and frequencies by tests in production on 100% of the devices with an ambient temperature at TA=25 C and TA=TAmax (given by the selected temperature range). Data based on characterization results, design simulation and/or technology characteristics are indicated in the table footnotes and are not tested in production. Based on characterization, the minimum and maximum values refer to sample tests and represent the mean value plus or minus three times the standard deviation (mean3).

Typical values
Unless otherwise specified, typical data are based on TA=25 C and VDD=5 V. They are given only as design guidelines and are not tested. Typical ADC accuracy values are determined by characterization of a batch of samples from a standard diffusion lot over the full temperature range, where 95% of the devices have an error less than or equal to the value indicated (mean2).

EMC characteristics
Susceptibility tests are performed on a sample basis during product characterization.
Functional EMS (electromagnetic susceptibility)
Based on a simple running application on the product (toggling 2 LEDs through I/O ports), the product is stressed by two electromagnetic events until a failure occurs (indicated by the LEDs).
ESD: Electrostatic discharge (positive and negative) is applied on all pins of the device until a functional disturbance occurs. This test conforms with the IEC 1000-4-2 standard. FTB: A burst of fast transient voltage (positive and negative) is applied to VDD and VSS through a 100 pF capacitor, until a functional disturbance occurs. This test conforms with the IEC 1000-4-4 standard.
A device reset allows normal operations to be resumed. The test results are given in the table below based on the EMS levels and classes defined in application note AN1709.
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical application environment and simplified MCU software. It should be noted that good EMC performance is highly dependent on the user application and the software in particular. Therefore it is recommended that the user applies EMC software optimization and prequalification tests in relation with the EMC level requested for his application. Software recommendations: The software flowchart must include the management of runaway conditions such as:

Corrupted program counter Unexpected reset Critical data corruption (control registers...)
Prequalification trials: Most of the common failures (unexpected reset and program counter corruption) can be reproduced by manually forcing a low state on the RESET pin or the oscillator pins for 1 second. To complete these trials, ESD stress can be applied directly on the device, over the range of specification values. When unexpected behavior is detected, the software can be hardened to prevent unrecoverable errors occurring (see application note AN1015). Table 19.

Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU and DLU) using specific measurement methods, the product is stressed in order to determine its performance in terms of electrical sensitivity. For more details, refer to the application note AN1181.
Electrostatic discharge (ESD)

1. ADC accuracy vs. negative injection current: Injecting negative current on any of the standard (non-robust) analog input pins should be avoided as this significantly reduces the accuracy of the conversion being performed on another analog input. It is recommended to add a Schottky diode (pin to ground) to standard analog pins which may potentially inject negative current. The effect of negative injection current on robust pins is specified in Section 4.3.5. Any positive injection current within the limits specified for IINJ(PIN) and IINJ(PIN) in Section 4.3.5 does not affect the ADC accuracy. 2. Calibration is needed once after each power-up.

Electrical parameters
Analog power supply and reference pins
The VDDA and VSSA pins are the analog power supply of the A/D converter cell. They act as the high and low reference voltages for the conversion. Separation of the digital and analog power pins allow board designers to improve A/D performance. Conversion accuracy can be impacted by voltage drops and noise in the event of heavily loaded or badly decoupled power supply lines (see: General PCB design guidelines).
General PCB design guidelines
To obtain best results, some general design and layout rules should be followed when designing the application PCB to shield the noise-sensitive, analog physical interface from noise-generating CMOS logic signals.

Use separate digital and analog planes. The analog ground plane should be connected to the digital ground plane via a single point on the PCB. Filter power to the analog power planes. It is recommended to connect capacitors, with good high frequency characteristics, between the power and ground lines, placing 0.1 F and optionally, if needed 10 pF capacitors as close as possible to the STR7 power supply pins and a 1 to 10 F capacitor close to the power source (see Figure 23). The analog and digital power supplies should be connected in a star network. Do not use a resistor, as VDDA is used as a reference voltage by the A/D converter and any resistance would cause a voltage drop and a loss of accuracy. Properly place components and route the signal traces on the PCB to shield the analog inputs. Analog signals paths should run over the analog ground plane and be as short as possible. Isolate analog signals from digital signals that may switch while the analog inputs are being sampled by the A/D converter. Do not toggle digital outputs near the A/D input being converted.
Software filtering of spurious conversion results
For EMC performance reasons, it is recommended to filter A/D conversion outliers using software filtering techniques. Figure 23. Power supply filtering

Thermal characteristics
The average chip-junction temperature, TJ, in degrees Celsius, may be calculated using the following equation: TJ = TA + (PD x JA) Where: - - - - - TA is the ambient temperature in C, JA is the package junction-to-ambient thermal resistance, in C/W, PD is the sum of PINT and PI/O (PD = PINT + PI/O), PINT is the product of IDD and VDD, expressed in Watts. This is the chip internal power, PI/O represents the power dissipation on input and output pins; user determined. (1)
Most of the time for the applications PI/O < PINT and may be neglected. On the other hand, PI/O may be significant if the device is configured to drive continuously external modules and/or memories. An approximate relationship between PD and TJ (if PI/O is neglected) is given by: PD = K / (TJ + 273C) Therefore (solving equations 1 and 2): K = PD x (TA + 273C) + JA x PD2 Where: - K is a constant for the particular part, which may be determined from equation (3) by measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD and TJ may be obtained by solving equations (1) and (2) iteratively for any value of TA Thermal characteristics

Known limitations
Low power wait for interrupt mode
When the STR73x device is put in Low Power Wait For Interrupt mode (LPWFI), the Flash goes into low power mode or power down mode, depending on the setting of the PWD bit in the Flash Control Register 0 (default is `0', Low Power mode). This default mode can create excessive voltage conditions on the transistor gates and may affect the long term behavior of the Low Power mode circuitry. Workaround There is no workaround. If Low Power Wait For Interrupt mode is used, it is strongly suggested to configure the Flash to enter power down mode (bit PWD = `1').
7.2
PLL free running mode at high temperature
When the STR73x device is operated and an ambient temperature (TA) of more than 55 C and the main system clock (fMCLK) is sourced by the PLL in free running mode, the device may not work properly. Workaround At high temperature (more than 55 C), it is recommended to use the internal RC oscillator as a backup clock source rather than the PLL free running mode.
