Overview
73S1215F-44IMR/F/P 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, 5×6 hardware-scanned PINpad, 64 KB Flash, 2 KB XRAM, and real-time clock with 32.768 kHz oscillator support. It operates from 2.7–3.6 V and supports -40°C to +85°C industrial temperature range.
For engineers reviewing the 73S1215F-44IMR/F/P datasheet, 73S1215F-44IMR/F/P pinout, 73S1215F-44IMR/F/P application, or 73S1215F-44IMR/F/P equivalent, this page delivers verified technical context on CCID-compliant USB smart card readers, embedded PINpad firmware execution, EMV transaction processing, and low-power standalone operation with RTC and battery voltage monitoring.
Technical Context
The 73S1215F-44IMR/F/P implements a single-cycle 80515 core running at up to 24 MHz (20 MIPS), enabling AES/DES/3-DES and RSA-based PIN encryption in firmware. Its integrated USB 2.0 Full-Speed peripheral includes four endpoints with dedicated FIFOs (16B control, 32B interrupt IN, 128B bulk IN/OUT) and PC/SC compliance.
Smart card interface provides full EMV 4.1 support with programmable LDO (1.8/3.0/5.0 V), T=0/T=1 UART with dual 2-byte FIFOs, 6 kV ESD protection, and activation/deactivation sequencers. The 5×6 keypad engine performs hardware scanning, debouncing, and scrambling without CPU intervention.

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 (48 MHz), 256 KB Flash, no integrated PINpad engine; requires external keypad controller | Targets higher-end, multi-interface terminals (contactless + contact); lacks hardware PINpad acceleration | Choose when needing ARM ecosystem compatibility and larger memory, but accept added BOM and firmware complexity for keypad handling |
| NXP SLN10SE101K1 | ARM Cortex-M0+, 128 KB Flash, integrated capacitive touch interface (not matrix keypad); USB HID only - no native CCID support | Optimized for touch-based authentication devices; lacks EMV 4.1–certified ISO 7816 stack and T=1 protocol support | Choose for touch-centric HSM peripherals where contact smart card compliance is secondary to UI flexibility |
Compared with Infineon SLE78CLX2040P and NXP SLN10SE101K1, the 73S1215F-44IMR/F/P uniquely combines certified EMV 4.1, CCID-compliant USB, and hardware-accelerated 5×6 PINpad in a single chip - reducing design risk and certification effort for cost-sensitive, high-volume USB PINpads.
