Introduction
The Cellular Card Phone RPE–1 is a GSM class 5 compatible cellular phone
without a battery or user interface of its own. Instead, the device is computer
controlled through the 68–pin PCMCIA connector. This connector is used to:
– 1) supply the card with all operating power it needs
– 2) transfer operating commands and their responses,
– 3) transfer digitized speech or GSM data and control messages and
– 4) during production or servicing transfer tuning parameters and FLASH
download data.
Physically the RPE–1 is compatible with the PC Card ’95 standard
(and earlier PCMCIA standard) for type II extended cards.
Technical Summary
The Nokia Cellular Card Phone RPE–1 hardware comprises four basic func-
tional blocks:
Technical Documentation
– 1) Rotatable Helix antenna
– 2) RF, a low power and low profile derivative from DCT2 (HD843)
– 3) BB, mixed DCT2 (RFI2) and DCT3 (MAD2)
– 4) Host interface/system control through RPE–1 specific ASIC ”SMART”

Technical Documentation
GSM functionality:
The RPE–1 is a GSM phase I type approved cellular telephone with maximum
output power of 0.8W (power class 5). The following GSM services are sup-
ported:
– voice,
– non–transparent and transparent data,
– fax
– SMS.
RF Section:
The RPE–1 interfaces to its surroundings through a rotatable helix antenna.
Alternatively, the helix can be removed and a plug for an external antenna in-
serted instead. Because the RPE–1 antenna connector is Nokia specific, a
dedicated external antenna cable with a standard FME–connector at the other
end must to be used.
The power amplifier is optimized for use at 3.3V supply voltage. Voltages up to
5.25V voltages are accepted, but excessive heat is generated.
System Module
Baseband:
The baseband consists of three ASICs: MAD2 system control ASIC, SMART
PCMCIA interface ASIC and DCT2 based BB/RF interface ASIC RFI2. The
baseband is basically similar as DCT3 baseband, differences are in powering
and added interface to host computer via SMART ASIC and a PCMCIA connec-
tor.
The baseband performance is optimal at 3.3V supply voltage. Higher supply
voltage up to 5.25V are usable, but excessive heat is generated.
Baseband memory mapping is shown below.

System Module
Software Section:
The RPE–1 includes MCU (Main Control Unit) software and DSP (Digital Signal
Processing) Software. MAD2 ASIC contains MCU processor (ARM) and DSP
processor (LEAD). MCU and DSP softwares are based on DCT3 GSM soft-
ware packages. Internal data functionality has been added on RPE–1 soft-
ware.
Host control interface:
This interface is a standard PCMCIA card interface, which is based on PC Card
’95 release.
Audio interface:
The audio interface is handled by the host computer audio interface (voice
card, speaker/headphones and microphone). Kindly refer to the audio specifi-
cation.
Technical Documentation
Modes of Operation
Standard PCMCIA mode:
This is the standard operating mode of the RPE–1. The card is used as a stan-
dard 8–bit PCMCIA I/O device. The host PC automatically configures its inter-
nal memory and interrupt mapping based on so called CIS (Configuration In-
formation Structure, specified in PC Card ’95 standard ) memory contents
stored inside the SMART ASIC within the RPE–1 baseband.
The RPE–1 is controlled through a number of memory mapped registers. The
digital audio interface is supported through a dedicated FIFO buffered memory
locations.
Vertical (i.e. non–PCMCIA) mode:
For host devices not having a free PCMCIA slot the RPE–1 has been designed
to support also direct serial bus operation. In this mode the PCMCIA connector
is no longer literally a PCMCIA connector, but a number of connector signals
have been redefined to support new logical interfaces.
The typical RPE–1 host interface is RS232C. The application specific socket
for the Cellular Card Phone is assumed to contain all 3.3V to RS232C buffering
circuitry, a 3.3V max. 1A supply regulator and a system RESET generator.
Should also voice calls be required in the application, the related codec and
analog amplifying circuitry would become essential as well.
Page 3–8
The vertical operating mode is activated by grounding pin 62 (SPKR#/BVD2) in
the PCMCIA connector before card RESET is released. Pin 62 (SPKR#/BVD2)
must be kept grounded all the time when operating in non–PCMCIA mode.

Baseband Block
Introduction
This document specifies the BB section of the GX8 RF/system module for
RPE–1 Transceiver Card The BB section of the GX8 employs the MAD2 ASIC
from DCT–3, RFI2 (RF/BB interface ASIC) from DCT–2, and a new ASIC
named as SMART to interface to a PCMCIA slot, and to a GSM phase I SIM
reader. The main guideline for the baseband block is the PC Card ’95 release,
which contains considerable hardware and software enhancements compared
to the earlier versions of the PCMCIA standard. Another important set of proposals is included in the ExCA specification that provides a more narrow definition of PC Card technology for PC architecture machines. The current revision
of the ExCA standard is Release 1.50 .
Modes of Operation
The Baseband in RPE–1 operates in one of the several operating modes. All
modes except one are normal PCMCIA modes. One mode is for use in non–
PCMCIA environments. The diagram below presents both physical operating
and logical sub operating modes.
System Module
RPE–1 can be used in systems where standard PCMCIA host controller is not
available. In non–PCMCIA mode the PCMCIA interface is bypassed inside the
interface ASIC so that the MBUS, FBUS and PCM speech data signals are
brought directly to the PCMCIA connector.

Normal operation mode
In the normal operating mode the RPE–1 acts as a cellular telephone without
built–in UI. After power–up the PCMCIA interface is first in memory mode, during which the host computer reads the PC CARD standard CIS information
from the RPE–1 card. The CIS is stored in the internal ROM of the SMART
interface ASIC. After reading the CIS the interface goes into I/O mode for runtime operation. One bit in the SMART operation control register determines
which mode is being used.
In normal operation the card looks like a modem card to the host computer. The
operation interface emulates a 16C550 UART. Control data for the RPE –1
goes through the UART to the internal FBUS of system ASIC MAD2. In addition there is an USRT through which speech data flows. It has its own control
and data registers in the interface ASIC. All this is implemented in the SMART
ASIC.
Flash programming mode
The Flash programming mode is used in updating the card software. The host
computer and the RPE–1 control software in it control the Flash download procedure.
Technical Documentation
During Flash programming the FBUS operates in synchronous mode with the
MBUS signal acting as a clock. The data to be downloaded to the RPE–1 goes
through the FBUS. The SMART ASIC generates the clock. The Flash mode is
selected with a bit in SMART operation mode control register.
Non–PCMCIA mode
RPE–1 can be used in applications where standard PCMCIA interface is not
available. Non–PCMCIA mode offers a simple interface for controlling it. The
controller thus does not have to be a personal computer but a simple microcontroller is enough.
Non–PCMCIA mode is activated by connecting pin ”BVD2/SPKR#” to the
ground on the host side of the PCMCIA connector. When this signal is 0 the
interface ASIC enters the non–PCMCIA mode and routes FBUS, flow control
signals and PCM speech data bus directly to the PCMCIA connector. Also A8
should be pulled down with 100k resistor to enable SMART ASIC sleep clock
feature. Internal registers of the interface ASIC are not accessible, so the ASIC
takes care of proper startup of the card. The external system must give a proper RESET signal.
In the non–PCMCIA mode MBUS is routed via a bidirectional switch directly to
the PCMCIA connector pin 29 A0. This switch is controlled by BVD2/SPKR#.
This allows user to control MAD2 with MBUS.

Electrical Characteristics
Introduction
The RPE–1 supply voltage must be in the range of 3.0 V to 5.25V. There is a
special undervoltage sensing supervisor circuit for stopping the Card if VCC
goes below the nominal 2.93V ( 2.92– 2.96V for the whole temperature range).
If the voltage goes below this value, SimCardDetX is driven LOW and power–
down sequence starts.

PCMCIA interface
All digital activity to external hosts go through the PCMCIA interface. This interface is handled by the SMART ASIC. In the SMART ASIC the PCMCIA interface section VCC is the PCMCIA connector VCC. The SMART ASIC uses
three independent supply voltages:
– for SIM interface VSIM supply,
– for PCMCIA interface VCC supply and
– for SMART ASIC core VCCARD supply.
The interface has two operating modes: one for PCMCIA compliant computer
hosts and one for non–PCMCIA hosts. Pin definitions depend on the mode.
The PCMCIA interface has two different pinouts. The first is the normal
PCMCIA pinout which conforms to the PC Card ’95 standard. The second
mode is the Nokia proprietary mode in which FBUS and PCM SIO buses are
connected directly to the PCMCIA connector. Also flow control signals, RESET,
and MBUS are routed to the connector. MBUS is used for synchronizing the
FBUS during data transfer in FLASH–mode. The PCMCIA connector pinouts
and corresponding electrical characteristics are listed in the next table.

SIM Interface
The SIM card connector is located in the baseband section. The system ASIC
MAD2 controls the SIM card. All signals go through the interface ASIC SMART
for level conversion.
While the baseband block operates on 3.0 V supply, phase I SIM cards require
a 5 V operating voltage. Level conversion for the signals is done in the interface
ASIC SMART. The I/O cells of the SMART for the SIM signals have a separate
5 V power supply. SIM signals are listed in the table below. All SIM signals
must be able to withstand short circuit to ground without damage.

SMART – MAD2 interface
The interface between the SMART and MAD2 ASICs is basically an asynchronous FBUS and a synchronous PCM bus. These serial buses are common for
all DCT3 phones. FBUS is there for transferring the control data between the
host computer and the system ASIC MAD2. The PCM bus transfers only
speech samples during a voice call. In normal phone speech samples would
go to speech codec.
The interface contains also the system RESET. The SIM interface is another
part of SMART–MAD2 interface.

MBUS interface
In PCMCIA modes the MBUS is generated by the SMART ASIC and used as
clock for FLASH downloading.
Page 3–20
In non–PCMCIA mode the MBUS is routed directly from the PCMCIA connector
pin 29 to the MAD2 MBUS pin 112 (SMART ASIC is bypassed). In this mode
the MBUS is bidirectional.
NOTE: MBUS logic levels must not exceed MAD2 VCC 3.0V.
