A set of instructions written in symbols and graphic representations in a logical language understood by computers; it is flexible but error-prone, requiring advanced skill to write computer progams in it.
The PIC16C925 and PIC16C926 are available in 64-pin TQFP and 68-pin PLCC packages and offer higher clock speeds of 20 MHz and 200 ns instruction cycle, 176 to 336 bytes of RAM and either 4k x 14 words or 8k x 14 words.
This innovative SiGe / CMOS approach thus enables Device Under Test (DUT)-cycle programming, where test waveforms are based on DUT timing needs and not constrained by a tester's instruction cycle rate.

Intended for use in a wide range of USB devices, the C161U moves data within peripherals at up to 10 times the rate of most competitive chips, thanks to its combination of superior speed, bandwidth, instruction cycle time and DMA (direct memory access).
