DATASHEET

General Description

The SC14441A/B/C, SC14442A are a family of digital

CMOS ICs with fully integrated radio transceivers

including RF Power Amplifier and baseband proces-

sors for DECT & DECT 6.0 CAT-iQ and Korean DECT

handsets and basestations. The program memory and

data storage resided in the a low cost, low pin count

Quad SPI (QSPI) Serial FLASH. The dual row LGA

approach provides a backward compatible pinning to

the SC14481 devices.

Refer to "SC14441, SC14442 Family overview." on

page 22.
