Dear Customer

With regard to the TLCS-870 Series OTP microcontrollers listed above, the following problem has been identified. If this issue presents you with any problem, please contact your local Toshiba sales office.

Problem

When the power supply start-up is over 10ms, a maximum of approximately 25 μA of DC current may pass through the OTP control circuit in some rare cases. On these rare occations, the supply current values in SLOW, SLEEP and STOP modes cannot meet the values specified in the technical datasheet.

There is no problem in other DC characteristics, and operational functions and mask ROM products.
