65 / 102 page  65 µPD17145(A1), 17147(A1), 17149(A1) 19. POC CIRCUIT (MASK OPTION) The POC circuit monitors the supply voltage. When the supply voltage is turned ON/OFF, it automatically resets the internal circuitry of the microcontroller. This circuit can be used in an application circuit with a clock frequency of 400 kHz to 4 MHz. The µPD17149 (A1) can be provided with the POC circuit by mask option. Caution The POC circuit is not provided to the PROM model ( µPD17P149). 19.1 Function of POC Circuit The POC circuit has the following functions: • Generates internal reset signal when VDD ≤ VPOC • Clears internal reset signal when VDD > VPOC (where, VDD: supply voltage, VPOC: POC detection voltage) Figure 19-1. Operation of POC Circuit 5.5 V 4.5 V VPOC 2.7 V 0 V Note 3 VDD Note 1 → t Reset Operation modeNote 4 Reset Operation guaranteed range Internal reset signal ↑ Note 2 Note 3 |
