W90P710 arduino
W90P710
y When reach middle and end address of destination address, a DMA_IRQ is requested to CPU
automatically
Smart Card Host Interface (SCHI)
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 General-purpose C4, C8 channels
SD/SDIO Host Interface
y Directly connect to Secure Digital (SD, MMC or SDIO) flash memory card.
y Supports DMA function to accelerate the data transfer between the internal buffer, external
SDRAM, and flash memory card.
y Two 512 bytes internal buffers are embedded inside the controller.
y No SPI mode.
KeyPad Scan Interface
y Scan up to 16 rows by 8 columns with an external 4 to 16 decoder and 4x8 array without auxiliary
component
y Programmable debounce time
