SC14480A5M, SC14480A2M6

1.8V Single Chip for DECT

General Description

■ A2M6: 2.6Mbit ROM + 16k shared RAM,

The SC14480A5M, SC14480A2M6 are family mem-

bers of digital CMOS ICs with fully integrated radio

transceivers and baseband processors for DECT &

DECT 6.0 CAT-iQ handsets and basestations.

■ A5M 5.0 Mbit ROM/FLASH +16k shared + 8k non

shared RAM.

■ ROM/FLASH access maximum 20.736 MHz

■ Instruction/Data/Event Trace unit in FLASH ver-

sion for fast program development.

The SC14480A5M has a FLASH version with CR16 ■ Power management

trace unit for development of all family members.

■ 1.8 Volt operating voltage with 1.8V I/O pads, P0

The radio transceiver, when combined with a power

amplifier and a Tx/Rx switch, implements a complete

l DECT radio transceiver compiant with the ETSI CTR6

standard.

tia The audio path comprises a 16 bit CODEC, analog

frontend, including a high efficiency 4 Ohm audio

amplifier (Class-D) and user programmable Gen2DSP.

n The CompactRISCTM CR16Cplus microprocessor with

a one wire debug port running from ROM controls the

e protocol stack and the I/O peripherals, keyboard,

fid UART, ACCESS bus, SPI, LED drivers, RF switches.
