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

sources and/or external memory

• Fifteen interrupt sources (including those from TICB,

BML and DSP) with two priority levels

• 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.
