This document introduces a 20MHz 16-bit microcontroller compatible with the industry standard MCS-96 instruction set. It features a register-to-register architecture, 1000-byte register RAM, three 8-bit I/O ports, an on-board interrupt controller, three pulse-width modulated outputs, high-speed I/O, a UART serial port, a dedicated baud rate generator, and software and hardware timers. The microcontroller is built using radiation-hardened process and design, with the ability to withstand ionizing dose and charged particles. It also includes error detection and correction for external memory accesses and is compliant with QML Q and QML V standards.
The UT80CRH196KD microcontroller from Aeroflex implements the MCS‑96 instruction set and is built on a radiation‑hardened CMOS process. It offers a 20 MHz core, 1000 byte register RAM, three 8‑bit I/O ports, and a range of integrated peripherals such as UART, PWM, and watchdog timer.
The device is packaged in a 68‑lead quad flat‑pack, is latch‑up immune up to LET > 128 MeV·cm/mg, and can operate in both 8‑bit and 16‑bit bus modes, making it suitable for space‑qualified control applications.
