The 83C750/87C750 is a family of 80C51 architecture microcontrollers from Philips Semiconductors with 1K/64 OTP/ROM and low pin count. They are suitable for logic replacement, consumer and industrial applications.
This document provides product specifications for the Philips 8XC750 family of 8-bit microcontrollers based on the 80C51 architecture. The devices are fabricated with high-density CMOS technology and offer features such as a 1k x 8 EPROM (for the 87C750), 64 x 8 RAM, and an on-chip oscillator.
The datasheet details various package options including 24-pin DIP, Shrink Small Outline Package, and Lead Chip Carrier. It also describes pin configurations for ports P0 through P3, reset functionality, and oscillator characteristics.

A high signal on the RST pin for two machine cycles while the oscillator is running resets the device.
A reset is accomplished by holding the RST pin high for at least two machine cycles.
