Introduction
This document helps the user to get started with the AT89STK09 starter kit.
The AT89STK09 is a starter kit for the AT83C26 device. The AT83C26 is a smart card
reader interface with 2 DC/DC converters allowing to manage up to 5 smart cards
including level shifters. This device needs TWI commands to configure its registers. This
device requires a host microcontroller (Smart Card Reader Microcontrollers, ARMs, ...)
with one or two ISO7816 Smart Card Interfaces.
Refer to the AT83C26 datasheet for further product information.

Section 2
Hardware
The AT89STK09 requires power supply, clock signal , smart card and TWI commands
to run. U1 connector is used to connect the AT83C26 host pins to the host microcontrol-
ler. The U1 connector pins are described on Table 2-1.
All passive components needed (inductors, capacitors) are soldered on board.
2.1
Power Supply
The host microcontroller signals voltage and the AT83C26 power supply are VCC. The
voltage range (VCC) is 3V to 5.5V, the maximum current consumption IVcc is about
250mA when all DC/DC convertors and LDO are activated. (Conditions : Vcc = 3V
60mA DC/DCa, 70mA DC/DCb).
2.2
2.3
Jumper
Configuration
The AT83C26 board has one jumper in order to set complete SC2 configuration.
The complete SC2 configuration (Smart Card including CC4 & CC8) is done by SW1
solder pad.
Host
The host microcontroller must provide the signals:
Microcontroller
Connection
•
•
VCC, VSS : Power supply signals - 3 - 5.5V @ 250mA
EVCC can be used when the Vcc host and Vcc are different. Generally the EVCC is
connected to VCC.
•
BYPASS is used to activate the low power consumption when connected to the host
microcontroller (high level must be supplied) - Generally the BYPASS is connected
to the ground.
•
•
A2, A1 : TWI address - Generally A2 = 0 and A1 = 0 during Reset
SDA, SCL : TWI signals to transmit/receive commands/status
Caution : TWI pull-ups have to be on the host microcontroller board
CLK signal is connected to host clock signal
•
Caution : The logic inverter (HC04 or other) is recommended if source clock is supplied
by output crystal oscillator buffer.
•
•
•
INT (Interrupt) : This signal must be connected to host interrupt input
CRST signal is connected to RST host microcontroller signal
CCLK signal is connected to the host smart card interface signal

Hardware
•
IO1, IO2, AUX1 and AUX2 are connected to the host smart card interface signals
depending on the configuration chosen. (Refer to the datasheet AT83C26)
