CMOS 8-Bit Microcontroller

The TMP87P809 is a high-speed, high-performance 8-bit single chip microcomputer, which has 64-Kbits One-Time PROM. The TMP87P809 is pin compatible with the TMP87C409B/809B. The operations possible with the TMP87C409B/809B can be performed by writing programs to PROM. The TMP87P809 can write and verify in the same way as the TC57256AD using an adapter socket and a general-purpose PROM programmer.
