73S1217F
Description
The Teridian Semiconductor Corporation 73S1217F is a versatile and economical CMOS System-on-Chip device intended for smart card reader applications. The circuit features an ISO-7816 / EMV interface, an USB 2.0 interface (full-speed 12Mbps - slave) and a 5x6 PINpad interface.
Key Features
- an ISO-7816 / EMV interface, an USB 2.0 interface (full-speed 12Mbps - slave) and a 5x6 PINpad interface
- Other built-in interfaces include an asynchronous serial and an I2C interface
- The System-on-Chip is built around an 80515 highperformance core
- The circuit requires a single 6 to 12 MHz crystal
- The respective 73S1217F embedded memories are; 64KB Flash program memory, 2KB user XRAM memory, and 256B IRAM memory
- On top of these memories are added independent FIFOs dedicated to the ISO7816 UART and to the USB interface
- The chip automatically powers-up the DC-DC converter with VBUS if it is present, or uses VBAT as the supply input
- Alternatively, the pin VPC can support a wider power supply input range (2.7V to 6.5V), when using a single system supply source
- The OFF mode can be alternatively initiated from the controller (firmware action instead of ON/OFF switch)
- In OFF mode, the circuit typically draws less than 1μA, which makes it ideal for applications where battery life must be maximized
