Smart Card Interface Module (EMV SIM)
21.1 Introduction
The Euro, MasterCard, Visa Subscriber Identification Module (EMV SIM) is designed to
facilitate communication to Smart Cards compatible to the EMV ver4.3 standard (Book
1) and Smart Cards compatible with ISO/IEC 7816-3 Standard.
21.1.1 Features
The EMV SIM module supports the following features:
• Supports Smart Cards based on the EMV Standard v4.3 and ISO 7816-3 standard
• Independent clock for SIM logic (trans receiver) and independent clock for
register read-write interface
• 4 byte deep FIFO for transmitter and receiver
• Automatic NACK generation on parity error and receiver FIFO overflow error
• Support for both Inverse and Direct conventions
• Re-transmission of byte upon Smart Card NACK request with programmable
threshold of re-transmissions
• Auto detection of Initial Character in receiver and setting of data format (inverse or
direct)
• NACK detection in receiver
• Independent timers to measure character wait time, block wait time and block guard
time
• Two general purpose counters available for use by software application with
programmable clock selection for the counters
• DMA support available to transfer data to/from FIFOs. Programmable option
available to select interrupt or DMA feature
