8-bit ETR Microcontroller
Overview
The LC87F83C8A/AU/96A/AU/64A/AU is an 8-bit ETR microcomputer that, centered around a CPU running at a
minimum bus cycle time of 74.04 ns, integrate on a single chip a number of hardware features such as 128K-bytes of
flash ROM maximum (onboard rewritable), 6K-bytes of RAM maximum, Onchip debugging, direct control of
necessary CD mechanism and CD-DSP for car audio, in the radio reception, the on-chip high-performance PLL circuit
provides a high-speed Lock-Up circuit to search for alternative frequency of RDS in a short time, the ability to control
the C/N characteristics of a local oscillator, and the high S/N through the direct PLL configuration, two sophisticated
16-bit timers/counters (may be divided into 8-bit timers), four 8-bit timers with a prescaler, a base timer serving as a
time-of-day clock, two synchronous SIO ports (with automatic block transmission/reception capabilities), an
asynchronous/synchronous SIO port, two UART ports (full duplex), four 12-bit PWM channels, an 8-bit 10-channel
AD converter, a high-speed clock counter, a system clock frequency divider, and a 29-source 10-vector interrupt
feature.
