Description

The KS88P2148 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the KS88C2148 microcontroller. It has an on-chip OTP ROM instead of a masked ROM. The EPROM is accessed by serial data format.

The KS88P2148 is fully compatible with the KS88C2148, both in function and in pin configuration. Because of its simple programming requirements, the KS88P2148 is ideal as an evaluation chip for the KS88C2148.
