TLCS-90 Series
TMP90P800
CMOS 8–Bit Microcontrollers
TMP90P800N/TMP90P800F
1. Outline and Characteristics
The TMP90P800 is a system evaluation LSI having a built in
One-Time PROM for TMP90C400/800.
A programming and verification for internal PROM is
achieved by using a general EPROM programmer with an
adapter socket.
The function of this device is exactly same as the
TMP90C400 by programming to the internal PROM.
The differences between TMP90P800 and TMP90C400
are the memory size (ROM/RAM).
The following are the memory map of TMP90P800 and
TMP90C400.
The TMP90P800N is in a Shrink Dual Inline Package
(SDIP64-P-750).
The TMP90P800F is in a Quad Flat Package (QFP64-P-
1420A).

(3) The 400-mode Bit and The Security Bit
The TMP90P800 has The 400-mode Bit and The Security
Bit in PROM cell. If The 400-mode Bit is programmed to
“0”, The TMP90P800 functions as its memory size is
same as TMP90C400 (ROM: 0000H ~ 0FFFH, RAM:
FF00H ~ FF7FH). If The Security Bit is programmed to
“0”, the content of the PROM is disable to read in
PROM mode. If both The 400-mode Bit and The
Security Bit is programmed to “0”, the memory size is
as same as TMP90C400 and its content of the PROM
is disable to read.
TMP90P800
How to Program The 400-Mode Bit or The Security Bit.
1) Connect A13, A14 and A15 pins to Vcc. [Otherwise
connect them to GND to program PROM. (address
0000H ~ 1FFFH)]
2) Set programming address to 0000H.
3) To program the 400-mode Bit, set D1 to “0”.
4) To program the Security Bit, set D0 to “0”.
5) Set D2 ~ D7 to “1” respectively.
The following table shows the 8-bit data to program
The 400-mode Bit or The Security Bit.
