LC875J48C

Overview

The SANYO LC875J64C/56C/48C are 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 64K/56K/48K byte ROM, 2048

byte RAM, 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 16-bit timer with a prescaler (may

be divided into 8-bit timers), a base timer serving as a time-of-day clock, 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 11-channel AD converter, two 12-bit PWM channels, a system clock frequency

divider, ROM correction function, and a 26-source 10-vector interrupt feature.
