LC66P2316
Four-Bit Single-Chip Microcontroller
with 16 KB of On-Chip OTP PROM
Preliminary
Overview
The LC66P2316 is an on-chip OTP PROM version of the
LC6623XX Series CMOS 4-bit single-chip micro-
controllers. The LC66P2316 is appropriate for program
development and product evaluation since it provides
identical functionality and pin compatibility with the
LC662316A.
