Product specification
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’.
