Digital telephone answering machine chip
PCD6003
12.1.1
DTAM
EXTERNAL MEMORY USING A PARALLEL FLASH
A parallel flash memory can be connected to the PCD6003 chip as shown in Fig.23. The MAGP and P2GP bits in the
XRAM-mapped Configuration Register (ConfReg) must be set. Clearing P4.3 will enable the flash memory.
12.1.2
DTAM
EXTERNAL MEMORY INTERFACE USING A
4-
WIRE SERIAL FLASH
A 4-wire serial flash memory (like SPI or Microwire flash memory) can be connected to the PCD6003 chip as shown in
Fig.24. P4.3 must be level shifted when using a 5 V serial flash memory. P4.1 and P4.2 must be pulled to 3 V with a
resistor. When using a 5 V flash memory the DO output of the flash must be level-shifted to 3 V with 2 resistors
(1 and 1.5 k
).
