3.5 P00/INT4 PIN AND RESET PIN OPERATING PRECAUTIONS P00/INT4 and RESET pins have the function (especially for IC test) to test PD75216A internal operations in addition to the functions described in sections 3.1 and 3.2. The test mode is set when a voltage larger than VDD is applied to one of these pins. If noise larger than VDD is applied in normal operation, the test mode may be set thereby adversely affecting normal operation. Since there is a display output pin having a high-voltage amplitude (35 V) next to the P00/INT4 and RESET pins, if cables for the related signals are routed in parallel, wiring noise larger than VDD may be applied to the P00/INT4 and RESET pins causing errors. Thus, carry out wiring so that wiring noise can be minimized, If noise still cannot be suppressed, take the measure against noise using the following external components. * Connect diode with small VF (0.3 V or less) between VDD and P00/INT4, RESET
VDD
*
Connect a capacitor between the pins and VDD.

XT1, XT2 AND P50 PIN OPERATING PRECAUTIONS
When selecting the 32.768 kHz subsystem clock connected to the XT1 and XT2 pins as the watch timer source clock, the signal to be input or output to the P50 pin next to the XT2 pin must be a signal required to be switched between high and low the minimum number of times (once or less per second). If the P50 pin signal is switched frequently between high and low, a spike is generated in the XT2 pin because of capacitance coupling of the P50 and XT2 pins and the correct watch functions cannot be achieved (the watch becomes fast). If it is necessary to allow the P50 pin signal to switch between high and low, mount an external capacitor to the P50 pin as shown below.

5.6 TIMER/PULSE GENERATOR The PD75216A incorporates one channel of timer/pulse generator which can be used as a timer or a pulse generator. The timer/pulse generator has the following functions. (a) Functions available in the timer mode * 8-bit interval timer operation (IRQTPG generation) enabling the clock source to be varied at 5 levels * Square wave output to PPO pin Functions available in the PWM pulse generation mode * 14-bit accuracy PWM pulse output to the PPO pin (Used as a digital-to-analog converter and applicable to tuning) 2 15 * Fixed time interval ( = 7.81 ms : at 4.19 MHz operation) interrupt generation fXX
(b)
If pulse output is not necessary, the PPO pin can be used as a 1-bit output port. Note If the STOP mode is set while the timer/pulse generator is in operation, miss-operation may result. To prevent that from occurring, preset the timer/pulse generator to the stop state using its mode register.

Note
Product quality may suffer if the absolute maximum rating is exceeded for even a single parameter, or even momentarily. In other words, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore, the product must be used under conditions which ensure that the absolute maximum ratings are not exceeded.

1. Calculation of total loss Design so that the sum of the following three power consumption values for the PD75216ACW/GF will be less than the total loss PT (It is recommended to use the system with 80 % or less of the rating). CPU loss Output pin loss : Given as VDD (MAX.) x IDD1 (MAX.) : There are normal output pin loss and display output pin loss. It is necessary to add a loss derived from the flow of maximum current to each output pin. Pull-down register loss : Power loss due to a pull-down resistor incorporated in the display output pin by mask option.
Example
Suppose 4-LED output with 9SEG x 11DIGIT, VDD = 5 V + 10 % and 4.19 MHz oscillation and let a current of 3 mA, 15 mA and up to 10 mA flow to the segment pin, timing pin and LED output pin, respectively. Further, let the voltage of fluorescent display tube (VLOAD voltage) be -30 V and normal voltage be small. CPU loss : 5.5 V x 9.0 mA = 49.5 mW Pin loss : Segment pin ..... 2V x 3 mA x 9 = 54 mW Timing pin ......... 2V x 15 mA = 30 mW 10 x 2 V x 10 mA x 4 = 53 mW 15 (30 + 5.5V)2 x 10 = 504.1 mW Pull-down resistor loss ........ 25 k LED output ........
PT = + + = 690.6 mW In this example, since the allowable total loss is 600 mW for the shrink DIP package, it is necessary to decrease power consumption by decreasing the number of on-chip pull-down resistors. In this example, power consumption can be adjusted to 577.8 mW by incorporating pull-down resistors in only 11 digit outputs and 7 segment outputs and externally mounting pull-down resistors to the 2 remaining segment outputs. 2. Except the system clock oscillator, display controller and timer/pulse generator. 3. The operating voltage range varies depending on the cycle time. Refer to the section describing AC characteristics.

Note
When the main system clock oscillator is used, the following should be noted concerning wiring in the area in the figure enclosed by a dotted line to prevent the influence of wiring capacitance, etc. * The wiring should be kept as short as possible. * No other signal lines should be crossed. Keep away from lines carrying a high fluctuating current. * The oscillator capacitor grounding point should always be at the same potential as VSS. Do not connect to a ground pattern carrying a high current. * A signal should not be taken from the oscillator.

When the subsystem clock oscillator is used, the following should be noted concerning wiring in the area in the figure enclosed by a dotted line to prevent the influence of wiring capacitance, etc. * The wiring should be kept as short as possible. * No other signal lines should be crossed. Keep away from lines carrying a high fluctuating current. * The oscillator capacitor grounding point should always be at the same potential as VSS. Do not connect to a ground pattern carrying a high current. * A signal should not be taken from the oscillator. The subsystem clock oscillator is a low-amplitude circuit in order to achieve a low consumption current, and is more prone to misoperation due to noise than the main system clock oscillator. Particular care is therefore required with the wiring method when the subsystem clock is used.
