W90P710
7.17 Smart Card Host Interface
The Smart Card resides in APB bus.
The whole chip of W90P710 operates at voltage level of 3.3 V except Smart Card Interface port's I/O
pins that are at 5 V to be compatible with mainstream Smart Card implementations. Advanced power
management feature further optimizes power consumption whether in operation or in power down
mode.
y ISO-7816 compliant
y PC/SC T=0, T=1 compliant
y 16-byte transmitter FIFO and 16-byte receiver FIFO
y FIFO threshold interrupt to optimize system performance
y Programmable transmission clock frequency
y Versatile baud rate configuration
y UART-like register file structure
y Versatile 8-bit, 16-bit, 24-bit time-out counter for Answer-To-Reset (ATR) and waiting times
processing.
y Parity error counter in reception mode and in transmission mode with automatic re-transmission.
y Automatic activation and deactivation sequence through an independence sequencer
