Data Sheet
January 2007
TheACE9050providesthecontrolandinterfacefunctions
needed for AMPS or TACS analog cellular handsets. The
device has been designed using Zarlink Semiconductor sub-
micronCMOStechnologyforlowpowerandhighperformance.
The ACE9050 contains an embedded microcontroller
and peripheral functions. The controller is of the 6303 type
with a Serial Communication Interface, Timer, ROM and
RAM. The peripheral functions are: Data Modem, SAT
Management, SerialChipInterfaces, I2CInterface, twoPulse
Width Modulators, IFC Counter, Tone generator, I/O ports,
Watchdog and Crystal Oscillator.
