Product details
Overview
The 73S1215F-68IMR/F from Teridian Semiconductor is an 80515-based System-on-Chip for smart card reader systems, integrating ISO 7816/EMV 4.1-compliant smart card interface, USB 2.0 Full-Speed (12 Mbps) device controller, and hardware-scanned 5×6 PINpad. It delivers up to 20 MIPS at 24 MHz CPU clock, features 64 KB Flash, 2 KB XRAM, and operates from 2.7–3.6 V (USB active), targeting handheld, CCID-compliant, and ExpressCard®-form-factor readers.
For engineers reviewing the 73S1215F-68IMR/F datasheet, 73S1215F-68IMR/F pinout, 73S1215F-68IMR/F application, or 73S1215F-68IMR/F equivalent, key selection criteria include EMV 4.1 compliance, integrated USB/ISO7816 dual-interface coexistence, on-chip RTC with 32.768 kHz oscillator support, programmable LED current drivers, and hardware keypad scanning with scrambling-critical for secure PIN entry in banking and government ID systems.
Technical Context
The 73S1215F-68IMR/F implements a single-chip solution where the 80515 core executes AES/DES/3-DES and RSA encryption routines at up to 20 MIPS, enabled by one-cycle-per-instruction execution and 24 MHz clocking. Its embedded USB 2.0 Full-Speed peripheral includes four dedicated endpoints (Control, Interrupt IN, Bulk IN/OUT) with FIFOs sized 16/32/128/128 bytes respectively.
Smart card interfacing is handled by a fully autonomous ISO 7816 UART supporting T=0 and T=1 protocols, with integrated LDO delivering selectable 1.8 V / 3 V / 5 V card power and 6 kV ESD protection on all interface pins. A separate 16-bit RTC timer driven by the optional 32.768 kHz crystal provides timekeeping independent of main CPU operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart card reader SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon SLE78CLX2040P | ARM Cortex-M0+ core, 256 KB Flash, no integrated PINpad hardware - requires external GPIO matrix controller | Lacks native 5×6 keypad scanner and scrambling; targets higher-end readers needing larger code space and BLE connectivity | Select when ARM toolchain compatibility and future wireless expansion (e.g., NFC/BLE) are prioritized over PINpad integration and cost-sensitive volume production. |

FAQ
What is the primary function of the 73S1215F-68IMR/F in smart card reader systems?
The 73S1215F-68IMR/F serves as a complete System-on-Chip for secure smart card readers, integrating an 80515 CPU core, ISO 7816/EMV 4.1 smart card interface, USB 2.0 Full-Speed device controller, and hardware 5×6 PINpad scanner. It enables single-chip implementation of CCID-compliant readers without external interface controllers or cryptographic accelerators - directly executing AES, DES, and RSA operations required for PIN encryption and transaction signing within the 73S1215F-68IMR/F itself.
Does the 73S1215F-68IMR/F support EMV Level 1 and Level 2 certification out of the box?
Yes, the 73S1215F-68IMR/F is designed to meet EMV 4.1 requirements at both Level 1 (electrical/protocol compliance) and Level 2 (transaction processing). Its integrated ISO 7816 UART supports T=0 and T=1 protocols with built-in activation/deactivation sequencers, auxiliary C4–C8 signaling, and 6 kV ESD protection - all validated per EMV standards. The 73S1215F-68IMR/F also ships with pre-approved EMV protocol libraries and CCID reference design, accelerating formal certification.
Can the 73S1215F-68IMR/F operate without an external crystal for the main clock?
No, the 73S1215F-68IMR/F requires an external 6–12 MHz crystal connected to CLKIN/XTAL1/XTAL2 pins to generate its primary system clock. An internal PLL then derives the 96 MHz MCLK used for USB and CPU operation. However, the optional 32.768 kHz RTC oscillator (RTC_XIN/RTC_XOUT) is independent and may be omitted if real-time clock functionality is not needed - the 73S1215F-68IMR/F will still operate fully for smart card and USB functions without it.
How does the 73S1215F-68IMR/F handle PIN security during keypad entry?
The 73S1215F-68IMR/F incorporates hardware-level PIN security through its dedicated 5×6 keypad interface, which performs on-die row/column scanning, contact debouncing, and bit-level scrambling of keypress data before it reaches RAM or CPU registers. This prevents PIN reconstruction via power analysis or electromagnetic side-channel attacks. All sensitive operations - including RSA encryption of PIN blocks - execute within the protected memory space of the 73S1215F-68IMR/F, with Flash lockable via on-silicon fuses to prevent firmware extraction.
Is the USB interface of the 73S1215F-68IMR/F compatible with standard PC/SC drivers on Windows and Linux?
Yes, the USB interface of the 73S1215F-68IMR/F is fully PC/SC compliant and implements the CCID (Chip/Smart Card Interface Device) class specification. Teridian provided a WHQL-certified Windows® driver and open-source Linux CCID driver support, enabling plug-and-play operation without custom driver development. The 73S1215F-68IMR/F enumerates as a standard CCID device using its four dedicated endpoints - Control, Interrupt IN, Bulk IN, and Bulk OUT - ensuring interoperability with existing middleware like OpenSC and Microsoft Smart Card Base Components.
