| PD75112(A), 75116(A) 4-Bit Single Chip-Microcomputer Data Sheet Description The PD75116(A) is one of the 4-bit single-chip microcomputer 75X series. The PD75116(A) is a product with the extended ROM capacity of the PD75108(A). In addition of high-speed operations, it can manipulate data in units of 1, 4 and 8 bits. In particular, the I/O operation of the PD75116 have been improved by a wide variety of bit control instructions. The PD75116 is provided with interface inputs/outputs with peripheral circuits having different power voltages, and analog inputs and suitable for controlling automobile electrical equipment, etc. For the PD75116(A), an on-chip pin-compatible one-time PROM product (PD75P116) is separately available for system development evaluation. Functions are described in detail in the following User's Manual, which should be read when carrying out design work.

When a voltage larger than VDD is applied to one of these two pins, the test mode is set. Thus, if noise exceeding VDD is applied even during normal operations, the test mode is set and normal operations may be discontinued. For example, if a cable from the P00/INT4 or RESET pin is too long, inter-wiring noise may be applied to the pin, the pin voltage may become larger than VDD, causing malfunctioning. Thus, carry out wiring to minimize inter-wiring noise. If the noise cannot be suppressed completely, carry out the following countermeasure against noise using an externally mounted component. o Connect a diode with low VF (max 0.3 V)between VDDs P80 to P83 VDD P90 to P93 P120 to P123 P130 to P133 P00/INT4, RESET Diode with low VF VDD P140 to P143 RESET NC Connect to VDD*1 Leave open or connect to VDD*2 o Connect acapacitor between VDDs *1: Only when a power-on reset generator is built in by mask option, connect t VDD. 2: When the PWB is shared with the PD75P116, connect the NC pin to VDD directly.

These pins are configured as shown in Figure 5-6. Sixteen threshold voltage (VREF) values (VDD x 0.5 -VDD x 16 15.5 16 ) are available and analog signals can be directly input. The analog input port can also be used as a digital 7.5 signal input port by selecting VDD x 16 for VREF.

Since this buffer can easily operate bits by sequentially changing address and bit specifications, it can be conveniently be used for bit-wise processing of data having long bit lengths.

PONF is mapped on bit 0 at address FD1H of the data memory space and is manipulated by a bit manipulation instruction However, it cannot be set(1) by the SET1 instruction. 22 PD75112(A), 75116(A) 6. Interrupt Functions There are seven types of interrupt sources for the PD75116(A) to allow multi-interruption with priority. The PD75116(A) is also provided with two types of edge detection testable inputs. The PD75116 interrupt control circuit has the following functions; * Hardware controlled vector interrupt function which enables to control by the interrupt enable flag (IExxx) and the interrupt master enable flag (IME) whether an interrupt should be enabled. * Interrupt start address can be set freely. * Multiple interrupt function which enables to specify priority by the interrupt priority select register (IPS). * Interrupt request flag (IRQxxx) test function (interrupt generation can be checked by the software). * Standby mode release (the interrupt to be released can be selected by the interrupt enable flag). 23 24 Internal Bus 2 IM1 2 IM0 9 Interrupt Enable Flag (IE x x x) (IME) 4 IPS 2 IST INT BT INT4 /P00 INT0 /P10 INT1 /P11 Edge Detection Circuit Edge Detection Circuit Edge Detection Circuit INTSIO IRQBT Decoder IRQ4 IRQ0 IRQ1 Priority Control Circuit IRQSIO Vector Table Address Generator INTT0 IRQT0 INTT1 INT2 /P12 INT3 /P13 Edge Detection Circuit Edge Detection Circuit IRQT1 IRQ2 Standby Release Signal IRQ3 Interrupt Request Flag Figure 6-1 Block Diagram of Interrupt Control Circuit PD75112(A), 75116(A) PD75112(A), 75116(A) 7.

This pulse is used in the three ways according to the specification of mask option of SWA and SWB shown in Figure 8-1 (refer to "10. Mask Option Selection"). Reset operations are shown in Figures 8-2 and 8-3.

If PCC=0011 is selected, 1 machine cycle becomes less than 0.95 s, with the result that the specified MIN. value of 0.95 s cannot be observed. Note: When using the main system clock oscillator, wiring in the area enclosed with the dotted line should be carried out as follows to avoid an adverse effect from wiring capacitance. * Wiring should be as short as possible. * Wiring should not cross other signal lines. * Wiring should not be placed close to a varying high current. * The potential of the oscillator capacitor ground should be the same as VSS. Do not ground wiring to a ground pattern in which a high current flows. * Do not fetch a signal from the oscillator. 5 40 PD75112(A), 75116(A) DC Characteristics (Ta = -40 to +85 C, VDD = 2.7 to 6.0 V) Parameter Input voltage high Symbol VIH1 VIH2 VIH3 Test Conditions Except for ports listed below Ports 0, 1, TI0, 1, RESET Ports 12 to 14 On-chip pull-upresistor Open drain VIH4 Input vltage low VIL1 VIL2 VIL3 Output voltage high VOH X1, X2 Except for ports listed below Ports 0, 1, TI0, 1, RESET X1, X2 VDD = 4.5 to 6.0 V, IOH = -1 mA IOH = -100A Output voltage low VOL VDD = 4.5 to 6.0 V Ports 0, 2 to 9, IOL = 5 mA Ports 12 to 14, IOL = 5 mA VDD = 4.5 to 6.0V, IOL = 1.6 mA IOL = 400A Input leakage current high ILIH1 ILIH2 ILIH3 Input leakage current low ILIL1 ILIL2 Output leakage current high ILOH1 ILOH2 Output leakage current low On-chip pull-up resistor ILOL RL VOUT = VDD VOUT = 12 V VOUT = 0 V Ports 12 to 14 VDD=5 V 10% 15 10 Supply current*1 IDD1 4.19 MHz crystal oscillation C1 = C2 = 22 pF VDD=5 V 10%*2 VDD=3 V 10%*3 HALT mode VDD=5 V 10% VDD=3 V 10% IDD3 STOP mode, VDD = 3 V 10% 3 0.55 600 200 0.1 40 VIN = 12 V VIN = 0 V VIN = VDD Except for ports listed below X1, X2 Ports 12 to 14 (for open drain) Except for X1, X2 X1, X2 Except for ports listed below Ports 12 to 14 (for open drain) MIN. 0.7VDD 0.8VDD 0.7VDD 0.7VDD VDD-0.5 0 0 0 VDD-1.0 VDD-0.5 0.25 0.40 1.0 1.0 0.4 0.5 3 20 20 -3 -20 3 20 -3 70 80 9 1.5 1800 600 10 TYP.
