T87C5101 Datasheet (ATMEL Corporation) - 8-bit Low Pin Count Microcontrollers

T87C5101, 8-bit Low Pin Count Microcontrollers

The T8xC5101/02 family is a high performance CMOS ROM, OTP, EPROM derivative of the 80C51 CMOS single chip 8-bit microcontroller.

The T8xC5101/02 family is a low pin count device where only Port 1, port 3 and 2/6 bits of a new port 4 are outputted.

This prevents any external access, like external pr
