Description

The HT83C51 is a monolithic 8-bit microcontroller that is pin equivalent to the Intel 8XC51FC microcontroller. Fabricated with Honeywell's dielectrically isolated high-temperature (HTMOS™) process, it is designed specifically for severe high-temperature applications such as down-hole oil well, aerospace, turbine engine and industrial control.

The HT83C51 uses the standard MCS-51 instruction set which is optimized for control applications. Pin-for-pin equivalent to the MCS-51 series product, it is compatible with all known development environments. Key features include the programmable counter array, watch dog timer, enhanced serial port for multi-processor communication and a hierarchical interrupt structure. Software selectable idle is included for reduced power. The HT83C51 varies from the standard 83C51FC, in that it supports half-duplex serial communication, and has 8K Bytes of Mask programmable ROM. The device is available in a standard pinout DIP, with optional packages considered.

These microcontrollers HT83C51 provide guaranteed performance supporting operating frequencies in excess of 16 MHz over the full -55 to +225°C temperature range. Typically, parts will operate up to +300°C for a year, with derated performance. All parts are burned in at 250°C to eliminate infant mortality.
