C605 and C604 (Preliminary Information)
1-6
built in pulse-density-modulated DAC (digital-to-analog converter) with direct
speaker-drive capability. The block diagram appearing in Figure 1–1 gives an
overview of the C614 functionality. IMPORTANT: a one bit comparator is not
currently supported.
Typical connections to implement reset functionality are shown in Figure 1–3.
1.5 C605 and C604 (Preliminary Information)
Two related products, the MSP50C605 (C605) and MSP50C604(C604) use
the C614 core. The C605 has a 224K byte data ROM built into the chip and
32 I/O port pins. The C605 can provide up to 30 minutes of uninterrupted
speech. The C604 is designed to support slave operation with an external host
microcontroller. In this mode the C604 can be programmed with a code that
communicates with the host via a command set. This command set can be de-
signed to support LPC, CELP, MELP, and ADPCM coders by selecting the ap-
propriate command. The C604 can also be used stand-alone in master mode.
The C604 and the C605 use the P614 as the development version device. De-
tails on C605 and C604 processors are found in Appendix A and B.
Note: MSP50C605 and MSP50C604
MSP50C605 and MSP50C604 are in the Product Preview stage of develop-
ment. For more information contact your local TI sales office. See Appen-
dices A and B for more information.
