sources and/or external memory
Fifteen interrupt sources (including those from TICB,
BML and DSP) with two priority levels
I
2
C-bus interface
UART with IrDA-compatible Data Transmission Mode
256 bytes of microcontroller main RAM
3 kbytes of microcontroller AUX RAM
1 kbyte of shared System Data RAM
64 kbytes of mask programmable ROM
128 kbyte address space for external ROM access,
maximum 192 kbytes together with internal ROM
128 kbytes of external RAM addressable
Embedded DSP with 6.912, 13.824 or 27.648 Mips
Speech and IOM-2 interface
BML for TDMA frame (de)multiplexing. Transmission or
reception can be programmed for any slot
Ciphering, scrambling, CRC checking/generation,
protected B-fields
Local call and B-field loop-back
Automatic receiver delay adjustment programmable per
slot to correct for terminal mobility
Phase error measurement and phase error correction by
hardware
Serial interface to synthesizer for frequency
programming
Programmable timing and polarity of radio-control
signals
Easy interfacing with radio circuits, operating at different
supply voltages
GMSK pulse shaper with two different pulse shapes
(BT = 0.5 and BT = 0.8)
Comparator for use as bit-slicer
3 channel time-multiplexed 8-bit ADC for RSSI, battery
and general input voltage measurement
Battery management supported by programmable
current source for temperature or charge current
measurement
On-chip 8-bit DAC for various purposes
Low power crystal oscillator at 13.824 MHz
Programmable on-chip capacitors for frequency
adjustment to 13.824 MHz with large pulling range
High performance DAC and ADC for dynamic earpiece
and dynamic or electret microphone
Analog-to-digital path switchable sensitivity for
microphone or line interface input
On-chip reference voltage and supply for electret
microphone
Very low ohmic buzzer output
Pulse density modulated or pulse width modulated
buzzer output signal
Power-on-reset
Low power operation optimized for 2 battery cells in
handset
Long standby time due to reduced digital supply voltage
and reduced activity in idle-locked mode
Flexible supply voltage concept due to use of level
shifters between each supply voltage domain
Eight independent supply voltage domains:
– 1.8 to 3.6 V for digital core, microcontroller ports P0
and P2, and also P1 and P3
– 1.8 to 3.6 V for buzzer, oscillator and battery
– 2.7 to 3.6 V for RF interface and analog circuits
CMOS technology
Small and flat LQFP80 package.
