LC875064B/56B/48B
8-Bit Single Chip Microcontroller with
64/56/48K-Byte EPROM and 2048-Byte RAM On Chip
Preliminary
Overview
The LC875064B/56B/48B microcontroller is 8-bit single chip microcontroller with the following on-chip functional blocks:
- CPU: Operable at a minimum bus cycle time of 100ns
- 64K/56K/48K bytes ROM
- 2048 byte RAM
- two high performance 16 bit timer/counters (can be divided into 8 bit units)
- two 8 bit timers with prescalers
- timer for use as date/time clock
- one synchronous serial I/O ports (with automatic block transmit/receive function)
- one asynchronous/synchronous serial I/O port
- 12-bit PWM × 2
- 3-channel × 8-bit AD converter
- high speed 8-bit parallel interface
- 16-source 10-vectored interrupt system
All of the above functions are fabricated on a single chip.
