1.2.2

Writing Method for General-purpose PROM Program

(1) Adapters

BM11118: TMP87PS39N

BM11138: TMP87PS39F

(2) Adapter setting

Switch (SW1) is set to side N.

(3) PROM programmer specifying

i)

PROM type is specified to TC571000D.

Writing voltage: 12.75 V (high-speed program mode)

ii) Data transfer (copy) (Note 1)

In the TMP87PS39, EPROM is within the addresses 04000H to 07FFFH, and

11100H to 1FFFFH. Data is required to be transferred (copied) to the addresses

where it is possible to write. The program area in MCU mode and PROM mode is

referred to “Program memory area” in Figure 1.1.1.

iii) Writing address is specified. (Note 1)

Start address: 04000H

End address: 1FFFFH

(4) Writing

Writing/Verifying is required to be executed in accordance with PROM programmer

operating procedure.

Note 1: The specifying method is referred to the PROM programmer description. Either

write the data FFH to the unused area or set the PROM programmer to access only

the program storage area.

Note 2: When MCU is set to an adapter or the adapter is set to PROM programmer, a

position of pin 1 must be adjusted. If the setting is reversed, MCU, the adapter and

PROM program is damaged.

Note 3: The TMP87PS39 does not support the electric signature mode (hereinafter referred

to as “signature”). If the signature is used in PROM program, a device is damaged

due to applying 12 V

0.5 V to the address pin 9 (A9). The signature must not be

used.
