LC87F2924B

Overview

The SANYO LC87F2924B 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 26K-byte flash ROM (onboard

programmable), 768-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, day and time counter, a high-speed clock counter, a synchronous

SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a

UART interface (full duplex), an 8-bit 13-channel AD converter, two 12-bit PWM channels, a system clock frequency

divider, frequency variable RC oscillation circuit, and a 26-source 10-vector interrupt feature.
