LC66E5316
Four-Bit Single-Chip Microcontroller
with 16 KB of On-Chip EPROM
Preliminary
Overview
The LC66E5316 is an on-chip EPROM version of the
LC6653XX Series CMOS 4-bit single-chip
microcontrollers. The LC66E5316 provides the same
functions as the LC665316A, and is pin compatible with
that product. Since the LC66E5316 is provided in a
window package, it can be reprogrammed repeatedly and is
thus optimal for program development.

鈥?Time limit timer, event counter, pulse width
measurement, and square wave output using a 12-bit
timer.
鈥?Time limit timer, event counter, PWM output, and
square wave output using an 8-bit timer.
鈥?Time base function using a 12-bit prescaler.
