LC662304A, 662306A, 662308A, 662312A, 662316A
Four-Bit Single-Chip Microcontrollers
with 4, 6, 8, 12, and 16 KB of On-Chip ROM
Preliminary
Overview
The LC662304A, LC662306A, LC662308A, LC662312A,
and LC662316A are 4-bit CMOS microcontrollers that
integrate on a single chip all the functions required in a
special-purpose telephone controller, including ROM,
RAM, I/O ports, a serial interface, a DTMF generator,
timers, and interrupt functions. These microcontrollers are
available in a 42-pin package.
