4-Bit Single Chip Microcontroller

SANYO -> Panasonic 

LC587404A/06A/08A

8. Interrupt Functions (5 sources with 4 vector addresses)

a) INT pin signal change (1 source)

b) Timer 1 (1 source)

c) Timer 2 (1 source)

d) Serial interface or SO4 pin signal change (either one)

9. Watchdog Timer

16-bit counter type. This can be reset at two different points so that it can be flexible for the application

use.

Watchdog timer operation time example

For the X’tal oscillation (32.768kHz, 1 or 2 oscillations) : 2000ms (Max)

For the CF oscillation (1MHz, 1 oscillation)

: 65.536ms (Max)

10. Sub-routine Stack

This has 8-level RAM for the use of stack. Therefore, the data RAM is not wasted when escaping to the

program counter.

11. Number of instructions

Useful instructions for the accumulator manipulation, transfer beteen the register memory, arithmetic

calculation, flag manipulation, IN/OUT port manipulation, conditional branch instructions etc are

available.

12. Oscillation Circuits (3 types)

a) 1 oscillation

One from the CF oscillation, RC oscillation or X’tal oscillation

b) 2 oscillations CF oscillation + X’tal oscillation or RC oscillation +X’tal oscillation
