controls. DSP includes two separate digital signal processors, fullrate speech cod-
ing, channel coding, data decryption and chiper key generation according to A52
algorithm.
CPU is 16 bit processor with a 2 megabyte memory address space. From this
address space a RAM circuit uses 128*8 kbits and flash PROM uses 1*8 Mbits.
HIGOLD uses a 13 MHz external clock derived from radio module TCXO. The inter-
nal clock can be run on either 6.5, 13 or 26 MHz.
Keypad is a 4*5 matrix and connected directly to HIGOLD IO pins. The display is a
graphical 32*95 pixel matrix including 23 symbols.
PIC processor (PIC16C620) takes care of Real Time Clock and has a protected
memory where IMEI information is stored. PIC has its own 32 kHz oscillator and it
runs independently and continuously (back up battery).
SIM card 3/5 V conversion IC. Since the logig runs on 3 V and the SIM card on 5 V
the LTC1555 takes care of the conversion.
Baseband power supply is a LTC1433 step down DC/DC converter.
