TMP86FS27

Pin Function

The TMP86FS27 has MCU mode and serial PROM mode.

(1) MCU mode

In the MCU mode, the TMP86FS27 is a pin compatible with the TMP86CM27/P27 (Make sure

to fix the TEST pin to low level).

(2) Serial PROM mode

The serial PROM mode is set by fixing TEST pin, P00 and P01 at “high” respectively when

RESET pin is fixed “low”.

After release of reset, the built-in BOOT ROM program is activated and the built-in flash

memory is rewritten by serial I/F (UART).
