LC868364A
8-Bit Single Chip Microcontroller with
64K-Byte ROM and 512-Byte RAM On Chip
Preliminary
Overview
The LC868364A microcontroller is an 8-bit single chip microcontroller with the following on-chip functional blocks:
- CPU: Operable at a minimum bus cycle time of 0.5µs
- On-chip ROM capacity: 64K bytes
- On-chip RAM capacity: 512 bytes
- Dot-matrix liquid crystal display (LCD) automatic display controller/driver
- External memory
- 16-bit timer/counter (or two 8-bit timers)
- 16-bit timer/PWM (or two 8-bit timers)
- 13-source 9-vectored interrupt function
All of the above functions are fabricated on a single chip.
Features
