Description
In addition, the embedded firmware and associated macrocells support handling and
protocol for the various interfaces:
● Single Wire Protocol (SWP) interface fully compliant with ETSI TS 102 613 Release 7
● I2C Slave interface fully compliant with NXP specification
● SPI Slave interface fully compliant with Freescale specification
● Asynchronous Receiver Transmitter in master configuration supporting ISO/IEC 7816-3
T=0 and T=1 protocols
The ST21NFCA is a serial access circuit based on a 8/16-bit CPU core. Operations will be
synchronized with an internally generated clock issued by the Clock Generator module. The
internal speed of the device is fully software programmable.
The CPU includes the Arithmetic Logic Unit (ALU), the control logic and registers controlled
by the ST21NFCA firmware. The CPU interfaces with the on-chip RAM, ROM and EEPROM
memories via a 24-bit internal bus offering 16 MBytes of linear addressing space.
This device also includes a True Random Number Generator (TRNG), three 8-bit fully
programmable timers, a Cyclic Redundancy Check (CRC3309) module, and a Data
Encryption Standard (DES) accelerator.
Thanks to an enhanced power switch system, the ST21NFCA is able to support several
power supply sources ("Battery On", Battery Low and Battery Off" modes) which manages
the power management of the device and its associated UICC.
