8-Bit Single-Chip Microcontroller

SANYO -> Panasonic 

LC865020B/16B/12B/08B

(3) Bus cycle time / Instruction cycle time

The LC865020B/16B/12B/08B microcontrollers are constructed to read ROM twice within one instruction cycle. This results

in 1.7 times better performance within the same instruction cycle compared to our 4-bit microcontrollers (the LC66000 series).

Bus cycle time indicates the speed to read ROM.

(4) Ports

- Input/output ports

: 6 ports (42 pins)

Input/output port programmable in nibble units

: 1 port (8 pins)

(However, when N-channel open-drain output is selected, bit-unit input is possible.)

Input/output port each bit programmable

: 5 ports (34 pins)

Include 15 V withstand N-channel open drain output port : 3 ports (18 pins)

- Input ports

: 2 ports (13 pins)

(5) A/D converter

- 8-channel × 8-bit A/D converter

(6) Serial-interface

- Two 8-bit serial-interface circuits

LSB first / MSB first functions switchable

- Internal 8-bit band-rate generator in common with two serial-interface circuits

(7) Timer

- Timer 0

16-bit timer/counter

2-bit prescaler + 8-bit programmable prescaler

Mode 0 : Two 8-bit timers with programmable prescaler

Mode 1 : 8-bit timer with programmable prescaler + 8-bit counter

Mode 2 : 16-bit timer with programmable prescaler

Mode 3 : 16-bit counter

The resolution of Timer is fixed to tCYC. (tCYC : cycle time)

- Timer 1

16-bit timer/PWM

Mode 0 : Two 8-bit timers

Mode 1 : 8-bit timer + 8-bit PWM

Mode 2 : 16-bit timer

Mode 3 : Variable-bit PWM (9 to 16 bits)

In Mode 0 and Mode1, the resolution of Timer and PWM is fixed to tCYC.

In Mode 2 and Mode 3, the resolution of Timer and PWM can be programmed to be tCYC or 1/2 tCYC

- Base timer

Every 500 ms overflow system for clock applications (using 32.768 kHz crystal oscillator for Base timer clock)

Every 976 µs, 3.9 ms, 15.6 ms, 62.5 ms overflow system (using 32.768 kHz crystal oscillator for Base timer clock)

- Base timer clock selectable

32.768 kHz crystal oscillator, system clock, and programmable prescaler output of Timer 0
