AR1900 Technology Overview
The AR1900 implements on a single chip a 1.9 GHz radio, modem, and TDMA
controller in support of the RCR STD-28 Version 3.3 PAS/PHS calling
features. It also implements all the functions required of a handset,
including applications processing on an ARM946E-S core, keypad and LCD
control, speaker and microphone voice path, and battery management.
Implemented in a standard CMOS process, the AR1900 brings a new level of
integration and cost competitiveness to the PAS/PHS market.

Applications
AR1900 System Architecture
 |
AR1900 Personal Handyphone System Handset
Board
The single-chip footprint of the AR1900 PHS solution enables a
new class of highly-compact, power-efficient handset designs.
Single-sided layouts with FR4 PCB material are possible for
either flip-phone or candy-bar style handsets. With the advanced
RF functions of the AR1900, features such as seamless roaming
are made possible with the appropriate software. Peripherals
such as cameras, MP3 players, and FM tuners, as well as a
secondary LCD, can be supported via expansion interfaces. An USB
1.1 client interface for PC download applications is supported
by the AR1900, as is a SIM slot for subscriber management. |
