TOSHIBA
TLCS-90 Series
TMP90P802A
CMOS 8–Bit Microcontrollers
TMP90P802AP/TMP90P802AM
1. Outline and Characteristics
The TMP90P802A is a system evaluation LSI having a built in
One-Time PROM for TMP90C802A.
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
TMP90C802A by programming to the internal PROM.
The following are the memory map of TMP91C640 and
TMP90C840A.
