Pin Description
Supply Voltage (V
The V
Clock (SCL/CLK)
In the asynchronous T=0 protocol, the SCL/CLK input is used to provide the device with a carrier frequency f. The
nominal length of one bit emitted on I/O is defined as an "elementary time unit" (etu) and is equal to 372/f. When the
synchronous protocol is used, the SCL/CLK input is used to clock data in on the positive clock edge and clock data out
on the negative clock edge.
Serial Data (SDA/IO)
The SDA pin is bi-directional for serial data transfer. This pin is open-drain driven and may be wired with any number of
other open drain or open collector devices. An external pull up resistor should be connected between SDA and V
nominal value of 4.7K ohm may be used. The value of this resistor and the system capacitance loading the SDA bus
will determine the rise time of SDA. This rise time will determine the maximum frequency during Read operations. Low
value pull up resistors will allow higher frequency operations while drawing higher average power supply current.
Reset (RST)
Atmel
sequence is activated, the device will output the data programmed into the 64-bit answer-to-reset register. When RST
is low, all internal logic, access-rights, and write cycles are in reset, except the asynchronous mode activation flag. A
weak internal pull-up on the RST input pad allows the device to be used in synchronous mode without bonding RST.
For synchronous only smart card applications, an external pull-up on RST is recommended to ensure synchronous
operation under any system timings or conditions. CryptoMemory does not support a synchronous answer to reset
sequence. The RST input is not available in the plastic package options for CryptoMemory.
