DATASHEET
SC14480A5M, SC14480A2M6
1.8V Single Chip for DECT
General Description
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.
The SC14480A5M has a FLASH version with CR16
trace unit for development of all family members.
For the family overview refer to SiTel Portal
SC1448x_product_overview.xls
The radio transceiver, when combined with a power
amplifier and a Tx/Rx switch, implements a complete
DECT radio transceiver compiant with the ETSI CTR6
standard.
The audio path comprises a 16 bit CODEC, analog
frontend, including a high efficiency 4 Ohm audio
amplifier (Class-D) and user programmable Gen2DSP.
The CompactRISCTM CR16Cplus microprocessor with
a one wire debug port running from ROM controls the
protocol stack and the I/O peripherals, keyboard,
UART, ACCESS bus, SPI, LED drivers, RF switches.
