73S1215F-44IM/F

Overview

The 73S1215F-44IM/F is an 80515 System-on-Chip designed for smart card reader applications. It integrates a USB 2.0 full-speed interface, ISO 7816/EMV smart card interface, and a 5x6 PINpad interface. The device features a high-performance 80515 core operating up to 24MHz with 64KB Flash, 2KB XRAM, and 256B IRAM. It supports AES, DES/3-DES, and RSA encryption. Operating voltage ranges from 2.7V to 3.6V (3V to 3.6V with USB active) and 4.75V to 5.5V for smart card supply. It operates between -40°C and 85°C in a 44-pin QFN package.

• Digital identification systems for secure login and government ID verification

Procurement Notes

Verify the specific suffix IM/F against the manufacturer's current documentation to confirm pinout and package compatibility. Confirm availability status directly with Analog Devices or authorized distributors as supply conditions may vary. Ensure the design environment supports the required software libraries for USB and EMV protocol layers prior to procurement.

Selection Notes

Select this component when a cost-effective solution combining USB connectivity and smart card reading is required. The integrated 80515 core provides sufficient processing power for encryption tasks without external microcontrollers. Consider the 44-pin QFN package constraints for PCB layout. Verify that the application requires the specific memory sizes and I/O configurations provided by this SoC.
