73S1215F-44IMR/F/P

Overview

The 73S1215F is an 8-bit microcontroller system-on-chip built around the 80515 core, designed for smart card reader applications. It integrates a USB 2.0 full-speed interface (12Mbps), ISO 7816/EMV smart card interface, and a 5x6 PINpad interface. The device features 64KB Flash program memory, 2KB user XRAM, and 256B IRAM. Operating at CPU clock speeds up to 24MHz, it delivers up to 20 MIPS processing power. It supports AES, DES/3-DES, and RSA encryption. The chip operates between 2.7V and 3.6V (3V to 3.6V with USB active) and includes a hardware watchdog timer, real-time clock, and multiple communication interfaces including UART and I2C.

Feature Summary

• Integrates USB 2.0 full-speed interface compliant with PC/SC standards alongside ISO 7816/EMV smart card interface supporting T=0 and T=1 protocols.
• Built-in 5x6 keypad interface featuring hardware scanning, debouncing, and scrambling capabilities for secure PIN entry.
• Includes dedicated FIFOs for ISO7816 UART and USB interface to optimize data flow and reduce processor overhead.
• Supports in-system programmable embedded Flash memory that can be locked via on-silicon fuses for production security.

Applications

• Hand-held PINpad smart card readers connected via USB or serial
• E-banking devices such as MasterCard CAP terminals
• Smart card reader modules for PC laptops and desktops using ExpressCard or USB form factors
• Digital identification systems requiring secure login and government ID verification

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm package type matches design requirements, as the device is available in both 44-pin and 68-pin QFN configurations. Ensure supply chain partners provide valid traceability documentation. Check current availability status as manufacturing schedules may affect lead times. Validate RoHS compliance certificates against specific ordering suffixes before finalizing procurement orders.

Selection Notes

Select this SoC when designing cost-effective smart card readers requiring integrated encryption processing. The 80515 core provides sufficient performance for EMV and USB protocol handling without external controllers. Consider the 44-pin QFN package for compact handheld designs where space is limited. Verify software library compatibility for pre-approved USB and EMV implementations. Evaluate power consumption profiles if battery-operated standalone operation is required.

Part Context

The 73S1215F belongs to the Teridian Semiconductor 73S1xxF family of smart card interface microcontrollers. Originally developed by Teridian, the product line was acquired by Maxim Integrated, which is now part of Analog Devices Inc. This series focuses on simplifying system integration for payment terminals by combining host controller functions with smart card interface logic in a single CMOS chip.

Replacement Considerations

Consult official datasheets for cross-reference information. No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate pinout compatibility and software API differences when considering alternative microcontrollers from other manufacturers.
