The Intel 21281DA is a 32-bit RISC microprocessor operating at a maximum clock frequency of 166MHz. This CMOS component features a 32-bit address bus and a 32-bit external data bus, with no integrated cache. It is housed in a 144-terminal, square, low-profile fine-pitch plastic flatpack (LFQFP) with a terminal pitch of 0.50mm. Designed for surface mounting, it supports boundary scan functionality and offers a low-power mode. Operating within a temperature range of 0°C to 70°C, its supply voltage ranges from 1.8V to 2.2V, with a nominal value of 2.0V. This component finds application in systems requiring efficient processing, including telecommunications and industrial control.
