LC87F2W48A
CMOS IC
50K-byte FROM and 1536-byte RAM integrated
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F2W48A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle
time of 83.3ns, integrates on a single chip a number of hardware features such as 50K-byte flash ROM (On-board-
programmable), 1536-byte RAM, an On-chip-debugger, sophisticated 16-bit timers/counters (may be divided into 8-bit
timers), a 16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with a
prescaler, a base timer serving as a time-of-day clock, a high-speed clock counter, a synchronous SIO interface, an
asynchronous/synchronous SIO interface, a UART interface (full duplex), two 12-bit PWM channels, a 14-channel AD
converter with 12-/8-bit resolution selector, a system clock frequency divider, an infrared remote controller receiver
circuit, and a 24-source 10-vector interrupt feature.
