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 µPD77019-013 can operate as simplified evaluate chip for as the µPD7701x family. About mask ROM and mask option, there are following differences between the µPD77019-013 and µPD77019. µ PD77019-013 PLL clock multiple rate Fixed to 4 µ PD77019 Variable multiple rate (1, 2, 3, 4, 8) by mask option Enable (PLL clock multiple rate is set to 1 by mask option.
