CMOS IC
FROM 128K byte, RAM 4096 byte on-chip
8-bit 1-chip Microcontroller
Overview
The LC877C00 series are an 8-bit single chip microcontroller with the following on-chip functional blocks. :
• CPU: operable at a minimum bus cycle time of 83.3ns
• 128K bytes Flash ROM (single 5V power supply, re-writeable on board)
• On-chip RAM: 4096 bytes
• LCD controller / driver
• 16-bit timer/counters (can be divided into 8-bit units)
• 16-bit timer / PWM (can be divided into two 8-bit timers)
• Four 8-bit timer with prescalers
• Timer for use as date/time clock
• Synchronous serial I/O port (with automatic block transmit / receive function)
• Asynchronous / synchronous serial I/O port
• 2 channel 12-bit PWM
• 12-channel × 8-bit AD converter
