LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B
8-Bit Single Chip Microcontroller
Preliminary
Overview
The LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B microcontrollers are 8-bit single chip microcontrollers
with the following on-chip functional blocks:
- CPU : Operable at a minimum bus cycle time of 0.5µs (microsecond)
- On-chip ROM Maximum Capacity : 48K bytes
- On-chip RAM Capacity : 1152/768/640/512 bytes
(LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B)
- 16-bit timer /counter (or two 8-bit timers)
- 16-bit timer /PWM (or two 8-bit timers)
- 8-channel × 8-bit AD converter
- Two 8-bit synchronous serial-interface circuits (1-channel × 16bit, 1-channel × 8bit)
- 14-source 10-vectored interrupt system
All of the above functions are fabricated on a single chip.
