PD77019-013
16 bits, Fixed-point Digital Signal Processor
The
碌
PD77019-013 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
碌
PD77019-013 internal ROM area is masked already by the void code to use as RAM based DSP without mask
code ordering process. Also the
碌
PD77019-013 can operate as simplified evaluate chip for as the
碌
PD7701x family.
About mask ROM and mask option, there are following differences between the
碌
PD77019-013 and
碌
PD77019.
碌
PD77019-013

mask ROM.
Enable to boot from internal data ROM or
external data area.
Clock output pin
Output internal system clock.
