Description

The KS88P2416/P2432 are OTP (One Time Programmable) version of the KS88C2432microcontroller.
The KS88P2416 microcontroller has an on-chip 16-Kbyte one-time-programmable EPROM instead of a masked
ROM. The KS88P2432 microcontroller has an on-chip 32-Kbyte one-time-programmable EPROM instead of a
masked ROM. The KS88P2416 is comparable to the KS88C2416, both in function and in pin configuration.
The KS88P2432 is comparable to the KS88C2432, both in function and in pin configuration.
