An integrated Infrared link is located on the top of the phone.
RH-13 System Module CCS Technical Documentation Engine Module 1AG Introduction This section describes the baseband part of the RH-13 transceiver. The BB architecture is similar to the earlier BB generation. The major difference is the integration level. Core BB consists of 2 ASICs and flash memory. BB core technical specification The core part of RH-13 BB (figure below) consist of 2 ASICs, UEM and UPP, and flash memory. Following sections describe these parts.
RH-13 System Module CCS Technical Documentation to energy management it performs all the baseband mixed-signal functions. Most of UEM pins have 2kV ESD protection and those signals, which are considered to be exposed more easily to ESD, have 8kV protection inside UEM. Such signals are all audio signals, headset signals, BSI, Btemp, Fbus and Mbus signals. Blocks REGULATORS UEM has 6 regulators for BB power supplies and 7 regulators for RF power supplies. VR1 regulator has 2 outputs VR1a and VR1b.
RH-13 System Module CCS Technical Documentation VCORE regulator supplies DSP and Core part of UPP. Voltage is programmable and startup default is 1.5V. Regulator goes to low Iq-mode in sleep mode. VSIM regulator supplies SIM card. Voltage is programmable. Regulator goes in to low Iqmode in sleep mode. VR1 regulator uses two LDOs and a charge pump. Charge pump requires one external 1uF capacitor in Vpump pin and 220nF flying capacitor between pins CCP and CCN. VR1 regulator is used by Safari_GTE RF ASIC.
RH-13 System Module CCS Technical Documentation DIGITAL IF Data transmission between the UEM and the UPP is implemented using two serial connections, DBUS (programmable clock) for DSP and CBUS (1.0MHz GSM and 1.08MHz TDMA) for MCU. UEM is a dual voltage circuit, the digital parts are running from 1.8V and the analog parts are running from 2.78V. AUDIO CODEC The baseband supports two external microphone inputs and one external earphone output.
RH-13 System Module CCS Technical Documentation UPP Introduction RH-13 uses UPPv8M ASIC. The RAM size is 8M. The processor architecture consists of both DSP and MCU processors. Blocks UPP is internally partitioned into two main parts: The Processor and Memory System (i.e. Processor cores, Mega-cells, internal memories, peripherals and external memory interface) is known as the Brain.
RH-13 System Module CCS Technical Documentation is 0.5mm. UIHW LCD Introduction RH-13 uses black/white GD51 96*65 full dot matrix display with COG driver. One vendor - SEIKO SED15B0 - is used in RH-13. Interface LCD data, clock, chip select and reset signals come from the UPP. The VIO voltage is supplied to a logic voltage pin and the FLASH1 voltage is used to supply power to the LCD. The LCD uses extra filtering capacitors to filter voltages.
RH-13 System Module CCS Technical Documentation key connects the PWONX of the UEM to the GND and creates an interruption. Side key detection is achieved by connecting the line to the ground when pressing the side key (volume up or down). The emifilter is the ESD and EMC protection. The matrix-based keyboard interface consists of a scan column I/O data register and a row of data register. In the keyboard scanning procedure, the MCU performs access to these registers to find out which key was pressed.
RH-13 System Module CCS Technical Documentation ters to find out which key was pressed. Scanning is an interrupt procedure, i.e., an interrupt is generated when key is pressed and then the MCU can start the scanning procedure. Side keys are also detected in the same way as other keys except that there is no metaldome, but the middle pin is directly connected to the ground. Table 2: Matrix of key detection lines S0 / P00 S1 / P01 S2 / P02 S3 / P03 S4 / P04 R0 / P10 Side key / Vol.

Vibra manufacturers for RH-13 are Namiki and Matsushita. Interfaces Vibra is controlled by PWM signal VIBRA from UEM. With this signal it is possible to control both frequency and pulse width of signal. Pulse width is used to control current when battery voltage changes.
RH-13 System Module CCS Technical Documentation Figure 5: SIM block UEM Technical information The SIM interface is split between UEM and UPP. This has been done in order to reduce the amount of interconnections on the SIM interface between the UPP and the UEM. The SIM interface control logic and UART is integrated into the UPP. The SIM interface startup and power down sequence, including timing and reset generation is implemented in UEM.
RH-13 System Module CCS Technical Documentation Interface The earpiece is driven directly by UEM (EARP and EARN). Both lines are ESD protected inside UEM (±8kV). The earpiece is connected on the PWB by spring connectors. Technical information The rated impedance of the earpiece is 32Ω and sensitivity at 1mW/1kHz is 103±3dB. The diameter of the earpiece is 13.2mm and the thickness is 2.7mm. For more detailed specification see data sheets under material code 5140067.

RH-13 System Module CCS Technical Documentation Interface Interface is compatible with Nokia 61XX and 51XX products. An accessory is detected by the HeadInt and HookInt line which are connected to system connector. The HookInt line is used to activate or end a call (only in HDC-9P).
RH-13 System Module CCS Technical Documentation Interface The transmit of the IR module goes as follow. Transmit is controlled by TXD line which comes from UPP. Between UPP and IR module there is UEM which makes lever-shifter from 1.8V to 2.78V. VBAT gives power supply to transmit led and serial resistor (R350) limits current. There is also filter capacitor (C351) on VBAT-line to give proper voltage. Receiving infrared data to IR led, it goes straight to UEM by RXD line.
RH-13 System Module CCS Technical Documentation Charger IF Introduction The charger connection is implemented through the system connector. The system connector supports charging with both plug chargers and desktop stand chargers. The charger is 2-wire or 3-wire galvanic charger. Connecting a charger creates voltage on VCHAR input of the UEM. When VCHAR input voltage level is detected to rise above VCHDET+ threshold by CHACON charging starts.
