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.
PLL clock multiple rate
Crystal resonator
connection
Clock Input pin
Clock output pin
Internal mask ROM
Self boot
Fixed to 4
µPD77019-013
Disable (PLL clock multiple rate is fixed to 4.)
External clock is connected to the X1 pin.
Leave the X2 pin open.
Output internal system clock.
Not available (already masked by the void
code)
Enable to boot from external data area (Boot
information data is masked.) Refer to 2.6
Boot Function.
µPD77019
Variable multiple rate (1, 2, 3, 4, 8) by mask
option
Enable (PLL clock multiple rate is set to 1 by
mask option.)
External clock is connected to the X1 pin.
Crystal is connected between the X1 pin and
X2 pin.
Low level fixed, or internal system clock
output is selectable by mask option.
Coding user program or data when ordering
mask ROM.
Enable to boot from internal data ROM or
external data area.
ORDERING INFORMATION
Part Number
µPD77019GC-013-9EU
Package
100-pin plastic TQFP (FINE PITCH) (14 × 14 mm)
The µPD7701x family consists of the µPD77016, 77015, 77017, 77018, 77018A and µPD77019.
