This Intel N80C251SB microcontroller features an 8-bit architecture built around the 80251 CPU core, operating at a maximum clock frequency of 12MHz. Constructed using CMOS technology, this component offers 1024 bytes of data RAM and supports a 16-bit address bus width. It includes 32 general-purpose I/O lines and an 8-bit external data bus. The device is housed in a 44-terminal PQCC44 (JESD-30 Code: S-PQCC-J44) square chip carrier package with J-bend terminals on a 1.270mm pitch, suitable for surface mounting. Operating within a temperature range of 0°C to 70°C, it requires a supply voltage from 4.5V to 5.5V, with a nominal 5.0V. This microcontroller is commonly found in industrial automation, consumer electronics, and automotive applications.
