NXP Semiconductors 80C31 series microcontroller, part number 80C31BH-16-BUA-T, is an 8-bit device featuring a ROM-less architecture with an 8051 CPU core operating at 16MHz. This CMOS technology component offers 128 bytes of internal RAM and supports external data bus widths of 8 bits, with an address bus width of 16 bits. It provides 32 programmable I/O lines and a nominal supply voltage of 5V, with a maximum of 6V, operating within a temperature range of -55°C to +125°C. The component is housed in a 44-terminal CQCC (Ceramic Quad Flatpack) package, with a terminal pitch of 1.27mm. Applications for this microcontroller span industrial automation, automotive systems, and consumer electronics where robust 8051 architecture is a requirement. Its 16.51mm square package dimensions and metal-sealed cofired ceramic construction ensure reliability in demanding environments.
