V.120c

V.120c LOGIC CIRCUIT

The main chip sets of Platform 2000 reference architecture
products consists of WALLY and CCAP IC. The memory
chips are the FLASH and the RAM.The WALLY includes the
functionality of CPU + DSP + CSP + CIA. The WALLY is M-
Core product (Motorola Proprietary) 32 bits. The CCAP IC
works in Buck mode and provides the power management
function of the phone. It also does the audio amplification and
routing. It controls the 32Khz crystal, it interfaces with
WALLY on 8 bit Parallel Bus. The communication to the
accessories through the CSS bus connector is done through the
CCAP IC. The audio through the external connector is digital.
All audio interface is through CCAP IC- Alert, Phone Speaker,
headset speaker & Microphone, External Speaker &
Microphone, and Phone Microphone
The Wally IC integrates the functionality of Casper IC (which
contains the MCU,
RIB, the CSP and the DSP) and CIA

Key features of the WALLY IC:

- M-Core integer processor, 32 bit RISC architecture
- 56600 NDE-UL DSP Core running at up to 70 Mhz @ 1.8V
- MCU-DSP interface
- CDMA signal processor (CSP3) ASIC
- 16 bit external memory interface for the MCU
- 8 bit parallel interface for CCAP
- 32-Input Interrupt Controller for the MCU
-Internal MCU ROM and RAM
- Special modules for CDMA mode
(all are MCU peripherals):
- Dual 9.8304 M samples/sec 4-bit ADCs
(RX I/Q with Receive AGC)
- Dual 4.9152 M samples/sec 9-bit DACs
- 13-bit linear CODEC
- 1-8bit, 2-10bit, 1-12bit measurement DAC
- 8-bit measurement ADC with 6 multiplexed inputs

Key features of the CCAP IC:

CCAP IC uses Buck converter mode with no 5V supply
The external memory consists of 32 Mega bit 1.8V FLASH and
4 Mega bit 1.8V SRAM
The butt plug is a 17 pin CE bus connector , which supports
the USB and RS232 Serial communications. CE bus runs at
1.8V.
V.120c Supports a complete line of accessories including FM
stereo. FM Radio headset (SYN8609) plugs into the CE bus
connector.
V.120c will not support the 3WB or PST mode of
communications.
