MC56F81xxx Series Digital Signal Controller
NXP's digital signal controller offers up to 128 KB Flash memory, 20 KB SRAM, and boot ROM
NXP's high-efficiency MC56F81xxx family is based on the high-performance 56800EX DSP core with frequencies up to 100 MHz. The MC56F81xxx is NXP’s first DSC product to integrate a digital signature algorithm security subsystem (DSASS) and a high-speed, low-power operational amplifier. Comparing with the MC56F82xxx family, the MC56F81xxx family extends the memory to 128 KB Flash, 20 KB RAM, and 64 KB boot ROM. The MC56F81xxx family has added lots of feature enhancements to the MC56F82xxx family, including enhanced DMA function (eDMA), configurable logic event generator (EVTG), dual 1.6 MS/s 12-bit ADC, and full PMBus support. The MC56F81xxx family is an extremely cost-effective solution for power conversion and motor control applications.
