PPS Support
AT88SC0104/0204/0404/0808/1616/3216/6416/12816/25616C
All CryptoMemory devices with user memory sizes 32Kbits and larger support the Protocol and
Parameter Selection (PPS) protocol, section 7 of ISO 7816-3. This section only applies to these
larger devices; PPS is not supported by CryptoMemory with memory sizes 16K bit or smaller.
At the end of an ATR sequence, subsequent to either a cold or a warm reset initiated by the
reader, the device will be expecting either a ‘Class’ byte as part of a command header, or the ini-
tial character, PPSS, of a PPS request. If the device receives a byte = $FF, it will process
subsequent incoming bytes as a PPS request. In all other cases, it will proceed with command
processing. There are 4 bytes that comprise a PPS request or response;
The following table shows the PPS1 values supported by CryptoMemory devices with memory
sizes 32K bits and above.
Table 8-1.
• Initial Character PPSS. Always equal to $FF.
• Format Character PPS0. CryptoMemory supports two response values for PPS0, $00 and
• Parameter Character PPS1. Encodes Fn and Dn in the same manner as TA(1) in the ATR
• Checksum PCK.
$01. See ISO 7816 for further definition of PPS0.
