Description

The KS88P2148 is an OTP (One Time Programmable) version of the KS88C2148 microcontroller. The KS88P2148 microcontroller has an on-chip 48-Kbyte one-time-programmable EPROM instead of a masked ROM.

The KS88P2148 is comparable to the KS88C2148, both in function and in pin configuration.
