MT6227 GSM/GP RS Baseband Processor Technical Brief Revision 1.00
Converter in the RF downlink path. Fu rthermore, to reduce
the need for extra external current-driv ing component, the
driving strength of some BPI outputs is designed to be
configurable.
Debug Function
The JTA G interface enables in-circuit debugging of
software program with the ARM 7EJ-S core. With this
standardized debugging interface, the MT6227 prov ides
developers with a wide set of options in choosing ARM
development kits fro m different third party vendors.
Power Management
The MT6227 offers various low-power features to help
reduce system power consumption. These features include
Pause Mode of 32KHz clocking at Standby State, Power
Down Mode for individual peripherals, and Processor
Sleep Mode. In addit ion, MT6227 is also fabricated in
advanced low leakage CMOS process, hence providing an
overall u ltra low leakage solution.
Package
The MT6227 device is offered in a 13mm×13mm, 296-ball,
0.65 mm pitch, TFBGA package.
