8-Bit Flash Microcontroller

LC87F57C8A

Overview

The LC87F57C8A is an 8-bit microcontroller built around a CPU block that operates with a minimum bus cycle time of 100 ns and that integrates 128 KB of flash ROM (that supports onboard programming), 4 KB of RAM, and an extensive set of peripheral functions on a single chip. The peripheral functions include two multifunction 16-bit timer/counters (that can be used as separate

8-bit counters), four 8-bit timers with prescalers, a clock time base timer, two synchronous SIO channels that provide an automatic transfer function, one asynchronous/synchronous SIO channel, two 12-bit PWM circuits, a 12-channel 8-bit A/D converter, a high- speed 8-bit parallel interface, a high-speed clock counter, a system clock divider function, and an interrupt function that supports 20 interrupts and 10 vector locations.
