TMP86FH46

Pin Function

The TMP86FH46 has MCU mode and serial PROM mode.

(1) MCU mode

In the MCU mode, the TMP86FH46 is a pin compatible with the TMP86C846/H46 (Make sure

to fix the TEST pin to low level).

(2) Serial PROM mode

The serial PROM mode is set by fixing TEST pin, P10 and P11 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).
