Writing an OTP type Microcontrollers-Recommended Flow

In the case of blank OTP (One Time PROM) type MCU, it is not

completely possible to screen defect parts that occur during assembly

process, because it is not possible to perform programming test after a

chip is assembled in a plastic package.

As a result, it is recommended to do the following screening process to

maintain quality and reliability of OTP type MCU after data are

programmed.

Programming and verification with an

EPROM programmer.

Stored in high temperature.

125°C, more than 20 hours.

Data verification with an EPROM programmer

Board assembly

For details of the initial failure rate of OTP-type microcontrollers when

screening is not performed at 125

°C for 20 hours or more after

programming, please contact your Toshiba local offices.
