1 FEATURES
• The PCD50912 is designed for GAP compatible DECT
handsets
• The PCD50922 is designed for GAP compatible DECT
base stations serving up to six handsets
• Fully static 80C51 microcontroller
• Emulation supported for 80C51 program development
• Four 8-bit ports (P0, P1, P2 and P3), 32 I/O lines
• Dedicated port pins for keyboard, I²C-bus, interrupt
sources and/or external memory
• Fifteen interrupt sources (including those from TICB,
BML and DSP) with two priority levels
• I²C-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.
