Intel S80C31BH is an 8-bit CMOS microcontroller from the S80C31 family, featuring an 8051 CPU core operating at a maximum clock frequency of 12MHz. This ROM-less device offers 128 bytes of on-chip data RAM and supports an 8-bit external data bus with a 16-bit address bus. It provides 32 general-purpose I/O lines, two external interrupt inputs, and one serial I/O port. The microcontroller includes two timers and a Boolean processor, along with on-circuit emulation capabilities for development. Designed for surface mounting in a 44-lead PQFP package, the Intel S80C31BH operates within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 25mA. Applications span industrial control, consumer electronics, and telecommunications equipment.
