73S1210F
Description
The 73S1210F is a versatile and economical CMOS System-on-Chip device intended for smart card reader applications. The circuit is built around an 80515 highperformance core; it features primarily an ISO-7816 / EMV interface and a generic asynchronous serial interface.
Key Features
- primarily an ISO-7816 / EMV interface and a generic asynchronous serial interface
- This makes the solution immediately able to support multi-card slots or multi-SAM architectures
- The circuit requires a single 6MHz to 12MHz crystal
- The respective 73S1210F embedded memories are 32KB Flash program memory, 2KB user XRAM memory, and 256B IRAM memory
- Dedicated FIFOs for the ISO 7816 UART are independent from the user XRAM and IRAM
- The chip automatically powers-up the DCDC converter with VBUS if it is present, or uses VBAT as the supply input if VBUS is not present
- 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
- Embedded Flash memory is in-system programmable and lockable by means of on-silicon fuses
