(1) PROM mode

The built-in PROM version has a PROM mode in addition to a nor-

mal operation mode. The PROM mode is used to write to and read

from the built-in PROM.

In the PROM mode, the programming adapter can be used with a

general-purpose PROM programmer to write to or read from the

built-in PROM as if it were M5M27C256K. Programming adapters

are listed in Table 26.Contact addresses at the end of this sheet for

the appropriate PROM programmer.

• Writing and reading of built-in PROM

Programming voltage is 12.5 V. Write the program in the PROM

of the built-in PROM version as shown in Figure 51.

(2) Notes on handling

➀

A high-voltage is used for writing. Take care that overvoltage is

not applied. Take care especially at turning on the power.

➁

For the One Time PROM version shipped in blank, Mitsubishi

Electric corp. does not perform PROM writing test and screening

in the assembly process and following processes. In order to im-

prove reliability after writing, performing writing and test

according to the flow shown in Figure 52 before using is recom-

mended (Products shipped in blank: PROM contents is not

written in factory when shipped).

Writing with PROM programmer

Screening (Leave at 150 °C for 40 hours) (Note)

Verify test with PROM programmer

Function test in target device

Since the screening temperature is higher
than storage temperature, never expose the
microcomputer to 150 °C exceeding 100
hours.
