PREFACE

The GPR400 (GEMPLUS Pocket Reader 400) is a Smartcard reader/writer
that has approximately the same dimensions as a Smartcard, and that fits
into a standard PCMCIA slot. When fitted into the PCMCIA slot, the
GPR400 leaves enough space for a Smartcard also to be inserted into the
PCMCIA slot beneath it, with its edges touching the Smartcard’s module
as shown in Figure 1 below. It therefore is an electrical adapter that is
compliant with the ISO 7816-3 Smartcard standard for PCMCIA products.

Fig 1: GPR400, PCMCIA Slot, and Smartcard Configuration

When the reader is connected to the PCMCIA interface, it is seen as an
I/O PC Card (type II) as defined by PCMCIA standard releases 2.0 and
above.

The GPR400 has 128 Kbytes of optional flash memory and 2 Kbytes of
RAM. The flash memory (if present) is used by the embedded
microcontroller with a 16 Kbyte partition and cannot be accessed directly
by the PCMCIA interface. It can be used for:

• Smartcard application executable files,

• data files, such as Smartcard blacklists or information files,

• other executable files, such as the extended memory for a

microcontroller.

PREFACE

 GEMPLUS 2

The RAM manages the PCMCIA interface as follows :

• 32 bytes are used for I/O data exchange,

• 2016 bytes are used as the Attribute Memory (defined by the

PCMCIA Standard 2.1 or by the PC Card Standard) and can
also be used as extended executable memory for the
microcontroller.

 GEMPLUS 3

THE GPR400 HARDWARE

The GPR400 Smartcard interface complies with ISO 7816-1,-2, and -3
standards and is compatible with embossed Smartcards. The GPR400 is
connected to a portable PC using a PCMCIA slot (socket).

The PCMCIA Connector

The GPR400 is compatible with all PCMCIA sockets that accept type II PC
Cards (5.0 mm in thickness). The GPR400 includes a standard 68 pin
connector.

The Smartcard module is compliant with the ISO 7816 - 2 standard.

GPR400 Architecture Overview

The GPR400 is based on a microcontroller. It communicates with the
PCMCIA bus using a specific component (ASIC) containing 2 Kbytes of
RAM.

The flash memory (128 Kbytes) is mapped onto the embedded
microcontroller. Please note this memory is optional in this release.

The GPR400 has an 8-bit data I/O structure.
The GPR400's power supply is provided by the PCMCIA interface

(Vcc=5V).

The 2K byte Memory

The GPR400 has 2K bytes of RAM included in the specific component.
These 2K bytes are mapped as follows:

I/O BUFFER

Attribute MEMORY

External RAM Space

and

32 Bytes

2016 Bytes

Smartcard registers

Figure 3. GPR400 2k Bytes RAM Structure

The first 2016 bytes are used to store the Card Information Structure
(C.I.S.), the specific PCMCIA defined registers for I/O PC Card
(Configuration Option Register), the registers for the Smartcard interface
and some external RAM data which are used by the embedded
microprocessor for external data space or executable programs (application
programs or Smartcard drivers). The C.I.S. is downloaded by the internal
microcontroller. The external RAM data can be loaded by the embedded
microcontroller or by the PCMCIA interface (Attribute Memory space
access).

The 32-byte I/O buffer is used to transmit application commands to the
microcontroller handling interface with the smart card.

THE GPR400 HARDWARE

 GEMPLUS 5

PCCard Configuration

When inserted into the computer, the GPR400 must be configured by the
host. To accomplish this, the host must first read the C.I.S. starting at
address 000h in the Attribute Memory. Then the GPR400 can be configured
using the Configuration Option Register (address FA0h) for an I/O base
address : 0300h, 0320h, 0340h, 0200h, 220h, 0240h or any space 32-byte
long memory space.

Configuration Option Register structure (see also PCCard Standard):

bit 7: set to 1, this bit initializes the GPR400 (minimum pulse of 5
µs)

bit 6-5 : reserved (reset to 0)

bit 4-0 : these bits are defined by the I/O base address as
described in the following table:

Configuration Option

18 300h-31Fh
19 320h-33Fh

10 200h-21Fh
11 220h-23Fh
12 240h-25Fh
01 all 32 bytes

boundary address

The register value 01 configures the GPR400 for all I/O addresses; the
INPACK signal is then systematically transmitted (see the PCCard
Standard).

SENDING COMMANDS TO THE READER

You can send the same commands to a Smartcard from the GPR400 as
those from any other reader. The command parameters will vary according
to the Smartcard, and they are listed in this section. For details regarding
available commands for each Smartcard, read the appropriate
documentation.

When you send a command to a Smartcard, you send it from the host to
the GPR400 I/O buffer. The microcontroller verifies that the command
format is correct; it then passes the command on to the appropriate
Smartcard.

You transmit commands to the GPR400 in a Type Length Variable (TLV)
format.

Note: When you develop applications for portable PCs that run on

batteries, bear in mind the following recommendation to limit battery
power consumption:

Power Off the Smartcard when you have finished accessing it, and

power down the GPR. This will switch the GPR400 into Power Down
mode.

Sending Commands to the GPR400

This section describes, in full detail, how to send Smartcard commands to
the GPR400. You send commands to the GPR400 through the 32-byte I/O
buffer. The first 2 bytes are specific registers and the other 30 bytes
(address 02h to 1Fh ) are used to store the TLV command. Four other
specific registers are located at the end of the Attribute Memory. The
following is a description of the 6 specific registers:

General Setup Register

Read only access: Address FB8h in the Attribute Memory
bit 4:= 0: Attribute Memory and I/O buffer locked
= 1: Attribute Memory and I/O buffer accessible

SENDING COMMANDS TO THE READER

 GEMPLUS 7

other bits: Internal use.

Smartcard Register 1

Read only access: Address FBAh in the Attribute Memory.
bit 4: = 1: Smartcard was pulled-out
= 0: Smartcard is in the reader
bit 7: = 1: Smartcard inserted
= 0: no Smartcard inserted
other bits : internal use

Smartcard Register 2

Read only access: internal use : Address FBCh in the Attribute Memory

Clock and Control Register

Read only access: internal use : Address FBEh in the Attribute Memory

Handshake Register

Handshake register (read and write): address 00h in the I/O buffer.
bit 0 : Master Reset : A “RESET GPR” sets this bit to a minimum

time of 5 microseconds and waits for 20 milliseconds. This
command is the first action to perform after a “POWER
DOWN GPR”: it reactivates the embedded microprocessor.
Note that the GPR400 is automatically reactivated when
inserted into the PCMCIA socket.

bit 1 : INTR : GPR400 interrupt request: After sending the GPR400

command in the I/O buffer, the host must set this bit to 1 in
order to launch the execution phase. This bit will be reset by
the GPR400 after the execution of the command.

bit 2 : BUSY/IREQ : this bit is an image of the PCMCIA pin IREQ

(Interrupt Request). The GPR400 sets this bit to 1 after
command execution, forcing the IREQ pin to 0. The host can
receive the command response and then reset this bit to 0.

bits 3 to 7 : for PRG control (see Using PRG section)

SENDING COMMANDS TO THE READER

 GEMPLUS 8

PRG Data register

The PRG Data register (refer to the “Using the PRG” section) is located at
address 01h in the I/O buffer.

Command and Response Format

The GPR400 command and response are structured in the TLV format.
This is as follows:

Type, Length, Variable

Description of the TLV Field

Type T

This value specifies the command on one byte. The command function is
one of the following:

• Select Card

• Open Session

• Close Session

• APDU Exchange

• Activate Driver

• Power Down GPR

• Load Memory

• Read Memory

• Exec Memory

• IFD Status

The response to a command is in the same location. The Type value is
equal to the command type value plus 02h (bit 1 set to 1).

Length L

This specifies the length, in bytes, of the V field, and must be a value from
1 to 28. The length field is coded on one byte.

SENDING COMMANDS TO THE READER

 GEMPLUS 9

Variable V

This field must be the same length as that specified in L. The command
itself will be entered in this field (see the list of commands later in this
section).

Chaining TLV fields

The maximum length of a standard TLV field is 30 bytes (length of the I/O
buffer). To transmit larger commands, the host can chain TLV fields. The V
variable is then divided into V1, V2, ... Vn and transported in the TLiVi
chaining field noted Tc ( 'c' for chaining ).

T, L, V <=> (Tc1,L1,V1) + (Tc2,L2,V2) +.. + (Tn,Ln,Vn)
Tc1 : first block (index 1) of a chaining field (index c)
Tn : Block n of the last chaining field (index c is not present)
L = L1 + L2 +.. + Ln
The index “c” corresponds to the value of bit 2 of type T with :
bit 2 = 1 : chaining field.
bit 2 = 0 : standard field or last field.
The maximum chaining field Length is : V1 + V2 + .. + Vn = 256 bytes

(this corresponds to a 256-byte buffer for data exchange with a Smartcard).

GPR400 Commands

Select Card

This command initializes the reader for the Smartcard protocol used in the
application. Note that by default the Smartcard interface is configured for
ISO T = 0 protocol, with the clock equal to 3.68 MHz. The T=1 protocol is
automatically set if the GPR400 recognizes the T=1 Smartcard during an
“OPEN SESSION” command.

SENDING COMMANDS TO THE READER

Open Session

This command powers the Smartcard on. The power on sequence is fully
compatible with ISO 7816-3 standards and determines whether the T=0 or
T=1 protocol will be used.

This command powers a Smartcard on and sends the Answer To Reset
(ATR) to the terminal. If the Smartcard is already powered on, then the
command merely returns the ATR (this function then permits either a cold
or a warm reset ).

Command Format

T = 20h
L = 00
Answer Format
Type Ta = Tc + 02h (22h)
Length L = Length (SmartCard Answer to reset) +1

This command powers off a Smartcard in compliance with ISO 7816
standards.

Command Format

T = 10h
L = 00
Answer Format
Type Ta = Tc + 02h (12h)
Length L = 01
Variable V = Reader Status Code

SENDING COMMANDS TO THE READER

 GEMPLUS 12

APDU Exchange

This command sends a request to a Smartcard (T=0 or T=1 or use of
downloaded drivers).

In this mode, the GPR400 relays the Transport Protocol Data Unit (TPDU)
command to the Smartcard, and then returns the TPDU response from the
Smartcard to the application.

The T=1 protocol management implemented by the GPR400 offers a
transparent mode mechanism. The other T=1 mechanisms, such as
chaining, retransmission, and resynchronization must be handled by the
external application.

The Exchange Data buffer for ISO Smartcards has a length of 256 bytes.

Command Format

T = 30h
L = Length of V field
V = Vex

where Vex = DIR, Vinf for T=0 protocol
ISO In command : DIR=00
Vinf = CLA, INS, P1, P2, Lin, Data IN

SENDING COMMANDS TO THE READER

 GEMPLUS 13

Activate Driver

This command validates a downloaded IC driver or a specific command
(subroutine) for the GPR400. The data corresponding to this driver or this
specific command must first be downloaded using the “LOAD MEMORY”
command. The downloaded IC Driver is used to exchange data with
Smartcards that do not support T=0 or T=1 (e.g. GPM256, GPM896, GFM,
GAM, etc...). The validated command is used to customize the GPR400 or
to create a new command.

SENDING COMMANDS TO THE READER

 GEMPLUS 14

Reset GPR

This command is not controlled by the GPR400. It is directly accessed
from the Handshake Register (refer to the “Handshake Register” section).

Power Down GPR

This command puts the GPR400 in low-consumption mode (Standby or
Power Down modes).

In Standby mode, when a Smartcard is inserted, a TLV Answer and an
interrupt signal are sent to the Host. If a Smartcard is already inserted, the
TLV is the GPR400’s only answer.

Note: This command does not power down the Smartcard interface (use
the Close Session command ).

Power Down is the GPR400’s very low-consumption mode (this applies
only if a “CLOSE SESSION” has been executed).

To reactivate the reader, you need to perform a “RESET GPR” before
sending any commands (refer to the “Handshake Register” section ).

A0 - A11 (Input): addresses A0 through A11 are address bus lines allowing

you to issue instructions directly to the Attribute Memory or to the I/O
buffer.

D0 - D7 (input/output): signals D0 through D7 make up the bi-directional
data bus. D7 is the most significant bit.

CE1 (input): GPR400 enable input signal. Active low.
OE (input): signal used to read the Attribute Memory. Active low.
WE (input): signal used to write Attribute Memory. Active low.
IORD (input): signal used to read I/O buffer. Active low.
IOWR (input): signal used to write in I/O buffer. Active low.
REG (input): signal to enable GPR400 access (Attribute Memory and I/O

buffer)
INPACK (output): indicates the GPR400 is inserted (correct I/O address).

Active low.
IREQ :(output) : Interrupt Request signal, indicates to the host that an

answer is available.
CD1,CD2 (outputs): these signals detect whether the GPR400 is inserted

or not. They are internally connected to the ground.
Vcc: GPR400 power supply (5V nominal) for all internal circuitry.
Vpp1: programming power supply, if the optional Flash Memory is present.
GND: ground for all internal circuitry.
BVD1, BVD2 (outputs): battery voltage detection. These signals are

internally driven high to maintain SRAM Smartcard compatibility.
RST (= RESET) : must be set to 1 by the host to reset the GPR400, then

reset to 0 during at least 20 ms.

APPENDIX C - SAMPLE GPR400
SCENARIOS

This appendix provides sample scenarios.

Scenario 1

GPR400 configuration at address 0240h in the host PC system resources.
This scenario is automatically done by the Socket and Card Services

(PCMCIA Standard) if it is found in the host (in compliance with PCMCIA
standard rel 2.1).

- Set the GPR400 power on.

- Read the C.I.S. in the Attribute Memory.

- Write (Attribute Memory ) at address 0FA0h the value 12h (as
mentioned in the C.I.S. configuration).
