AT88SC0204C
2022ES–SMEM–07/04
Protocol Selection
The AT88SC0204C supports two different communication protocols.
Smart Card Applications
: The asynchronous T = 0 protocol defined by ISO 7816-3
is used for compatibility with the industry’s standard smart card readers.
Embedded Applications
: A 2-wire serial interface is used for fast and efficient
communication with logic or controllers.
The power-up sequence determines which of the two communication protocols will be
used.
Asynchronous
T = 0 Protocol
This power-up sequence complies with ISO 7816-3 for a cold reset in smart card
applications.
V
CC
goes high; RST, I/O-SDA and CLK-SCL are low.
Set I/O-SDA in receive mode.
Provide a clock signal to CLK-SCL.
RST goes high after 400 clock cycles.
The device will respond with a 64-bit ATR code, including historical bytes to indicate the
memory density within the CryptoMemory family. Once the asynchronous mode has
been selected, it is not possible to switch to the synchronous mode without powering off
the device.
Figure 2.
Asynchronous T = 0 Protocol (Gemplus Patent)
Synchronous
2-wire Serial Interface
The synchronous mode is the default after powering up V
CC
due to the internal pull-up
on RST. For embedded applications using CryptoMemory in standard plastic packages,
this is the only communication protocol.
Power-up V
CC
, RST goes high also.
After stable V
CC
, CLK-SCL and I/O-SDA may be driven.

Note:
Five clock pulses must be sent before the first command is issued.
