Intel 21281BB is a 32-bit RISC microprocessor operating at a maximum clock frequency of 100MHz. This CMOS component features a 32-bit address bus and a 32-bit external data bus, supporting fixed-point operations. The device incorporates integrated cache and offers low-power modes for enhanced energy efficiency. It is housed in a 144-terminal PQFP (Plastic Quad Flat Pack) package with a terminal pitch of 0.50mm, designed for surface mounting. Boundary scan capabilities are included for improved testability. This microprocessor is suitable for applications within the industrial, networking, and consumer electronics sectors. The operating temperature range is 0°C to 70°C, with a supply voltage range of 1.5V to 1.8V, nominally 1.65V.
