TOSHIBA THP 804 9PI -6, TMP 8039P 1-6
8-BIT SINGLE-CHIP MI CROCOHPUTER
GENERAL DESCRIPTION
The TMP8049PI-6, from here on referred to as the TMP8049 , is a single chip
microcomputer fabricated in N-channel Silicon Gate MOS technology which
pr6vides internal 8-bit parallel architecture.
The following basic architectural functions of a computer have been
included in a single chip; an 8-bit CPU, 128
x
8
R.-\'~
data memory, 2K
x
8 ROM
program memory, 27 I/O lines and an 8-bit timer/event counter.
The TMP8049 is particularly efficient as a controller.
bit handing capability as well as facilities for both
arithmetic.
It has extensive
binary and BCD
The TMP8039PI is the equivalent of a TMP8049 without ROM program memory on
chip. By using this device wi th external EPROM Or
RAM,
software debugging
becomes easy.
