UMA1002

FEATURES

• Single chip solution to all the data handling and

supervisory functions

• Configuration to both AMPS and TACS

• Additional JTACS option

• I2C-bus serial control

• All analog interface and filtering functions fully

implemented on chip

• Error handling in hardware reduces software

requirements

• Robust SAT decoding and transponding circuitry

• Low current consumption by on-chip power-down

modes

• Reduced system current consumption by new

integrated power-saving features

– Majority voting includes more intelligence

– On-chip control filler word filter

– BCH error filter

– Possibility to program ESCC bits

• Small physical size: SO28 or LQFP32

• External peripheral component count reduced

– On-chip selectable clock divider

– Integrated pull-up resistor at TXLINE

• Simplified reset and abort software routines possible

• The SO28 version is fully compatible with UMA1000LT

and UMF1000T.

GENERAL DESCRIPTION

The UMA1002 is a low power CMOS LSI device

incorporating the data transceiving, data processing, and

SAT functions (including on-chip filtering) for an AMPS or

TACS hand-held portable cellular radio telephone.

In this data sheet, the UMA1002 is often referred to by the

descriptive term ‘DPROC2’.
