CMOS IC
128K/96K-byte ROM and 12288-byte RAM integrated
8-bit 1-chip Microcontroller
with USB-host controller
Overview
The LC871HC4A/92A 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 128K/96K-byte ROM, 12288-byte RAM, a
sophisticated 16-bit timer/counter (may be divided into 8-bit timers), a 16-bit timer (may be divided into 8-bit timers or
PWMs), four 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, 3 channels of synchronous SIO
interface with automatic data transfer capabilities, an asynchronous/synchronous SIO interface, a UART interface (full
duplex), a full-speed USB interface (host control function), an 8-bit 12-channel AD converter, 2 channels of 12-bit PWM,
a system clock frequency divider, an infrared remote control receiver circuit, and a 40-source 10-vector interrupt feature.
