The ACE9050 provides the control and interface functions
needed for AMPS or TACS analog cellular handsets. The
device has been designed using Mitel Semiconductor sub-
micron CMOS technology for low power and high performance.
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,
Serial Chip Interfaces, I
2
C Interface, two Pulse Width
Modulators, IFC Counter, Tone generator, I/O ports, Watchdog
and Crystal Oscillator.
Several power down modes are incorporated in the device
as is a processor emulation mode for software and system
development.
An index to this data sheet is given on pages 49 and 50.
