(6) 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, Renesas corp. does not

perform PROM writing test and screening in the assembly

process and following processes. In order to improve

reliability after writing, performing writing and test according

to the flow shown in Figure 34 before using is

recommended.

Writing with PROM programmer

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

Verify test with PROM programmer

Function test in target device

Note: Since the screening temperature is higher

than storage temperature, never expose the

microcomputer to 150 °C exceeding 100

hours.
