CMOS IC
FROM 32K byte, RAM 1024 byte on-chip
8-bit 1-chip Microcontroller
Overview
The LC87F7032A is an 8-bit single chip microcontroller with the following on-chip functional blocks:
• CPU: operable at a minimum bus cycle time of 250ns
• 32K bytes Flash ROM
• On-chip ΡΑΜ: 1024 bytes
• LCD controller/driver
• 16bit timer × 2ch + 8bit timer × 1ch or more
• Synchronous serial I/O port (with automatic block transmit/receive function)
• Asynchronous/synchronous serial I/O port
