LC66E2316
Four-Bit Single-Chip Microcontroller
with 16 KB of On-Chip EPROM
Preliminary
Overview
The LC66E2316 is an on-chip EPROM version of the
LC6623XX Series CMOS 4-bit single-chip micro-
controllers. The LC66E2316 provides the same functions
as the LC662316A, and is pin compatible with that
product. Since the LC66E2316 is provided in a window
package, it can be reprogrammed repeatedly and is thus
optimal for program development.
