TMP86FH46
CMOS 8-Bit Microcontroller
TMP86FH46N
The TMP86FH46 is a high-speed, high-performance 8-bit microcomputer built around the TLCS-
870/C Series core with built-in 16-Kbyte flash memory and it is pin compatible with its mask ROM
version, the TMP86C846/H46. Writing programs in the built-in flash memory enables this
microcomputer to perform the same operations as the TMP86C846/H46. The built-in flash memory
can be rewritten on board (without removing it from the PCB) by a built-in boot program.

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).

2.4 Interface Specifications for UART
The following shows the UART communication format used in serial PROM mode.
Before on-board programming can be executed, the communication format on the external
controller side must also be setup in the same way as for this product.
Note that although the default baud rate is 9,600 bps, it can be changed to other values as shown
in Table 2.4.1. The Table 2.4.2 shows an operating frequency and baud rate in serial PROM mode.
Except frequency which is not described in Table 2.4.2 can not use in serial PROM mode.
Baud rate (Default): 9,600 bps
Data length: 8 bits
Parity addition: None
Stop bit length: 1 bit

Note: “Reference Frequency” shows the high-frequency area supported in serial PROM mode.
Except the above frequency can not be supported in serial PROM mode.
2.5 Command
There are five commands in serial PROM mode. After reset release, the TMP86FH46 waits a
matching data (5AH).

Remarks
Matching data. Always start with this command after reset release.
Writing to area from C000H to FFFFH is enable.
Writing to area from 0050H to 0230H is enable.
The checksum of entire flash memory area (from C000H to FFFFH)
is output in order of the upper byte and the lower byte.
Product discrimination code, that is expressed by 13 bytes data, is
output.
