User Guide
Modem section consists of RAP3GS ASIC with NOR FLASH and DDRAM memory as the core. Memory package
POP2 is stacked on to RAP3GS. RAP3GS supports cellular protocols of WCDMA (3GPP R-4) and GSM (minimum
EDGE glass 10, GPRS phase2). Modem DDRAM memory have 128Mbits of memory and NOR flash have 128Mbits
of memory. RAP3G operates with the system clock of 38.4 MHz, which comes from the VCTCXO.
Application section includes application processor ASIC with DDR/NAND combo memory as the core.
Application processor uses 19.2MHz clock, which comes from the RAP3GS divided by two from the 38.4 MHz
system clock.
Application processor (OMAP1710) is also called as an application ASIC because it is processing application
SW and handles the UI SW. It consists of OMAP3.3 and peripheral subsystems like display- and keyboard driver
blocks.

Phone modes of operation
Mode Description
NO_SUPPLY
(dead) mode means that the main battery is not
present or its voltage is too low (below VILMA master
reset threshold) and that the back-up battery
voltage is too low.
BACK_UP
The main battery is not present or its voltage is too
low but back-up battery voltage is adequate and the
32kHz oscillator is running (RTC is on).
PWR_OFF
In this mode (warm), the main battery is present and
its voltage is over VILMA master reset threshold. All
regulators are disabled, PurX is on low state, the RTC
is on and the oscillator are off.
RESET
RESET mode is a synonym for start-up sequence.
RESET mode uses 32kHz clock to count the REST mode
delay (typically 16ms).
SLEEP
SLEEP mode is entered only from PWR_ON mode with
the aid of SW when the systems activity is low. There
are in principle three different sleep modes:
• Helen3 sleep
• RAP3GS sleep
• Helen3 and RAP3GS sleep (deep sleep)
