UPD77019-013 Description
PRELIMINARY DATA SHEET MOS INTEGRATED CIRCUIT µPD77019-013 16 bits, Fixed-point Digital Signal Processor The µPD77019-013 is a masked 16 bits fixed-point DSP (Digital Signal Processor) developed for digital signal processing with its demand for high speed and precision. The µPD77019-013 internal ROM area is masked already by the void code to use as RAM based DSP without mask code ordering process. Also the...
