Product details
Overview
73S1215F-68IM/F from Teridian Semiconductor is an 80515-based System-on-Chip for smart card readers, integrating ISO 7816/EMV 4.1, USB 2.0 Full-Speed (12 Mbps), and hardware-scanned 5×6 PINpad. It delivers 20 MIPS at 24 MHz CPU clock, with 64 KB Flash, 2 KB XRAM, and on-chip LDO for 1.8/3.0/5.0 V smart card supply - deployed in CCID-compliant handheld PINpads and ExpressCard® reader modules.
For engineers reviewing the 73S1215F-68IM/F datasheet, 73S1215F-68IM/F pinout, 73S1215F-68IM/F application, or 73S1215F-68IM/F equivalent, key selection criteria include EMV 4.1 compliance, dual-interface (USB + ISO 7816) coexistence, real-time clock support via 32.768 kHz oscillator, 6 kV ESD protection on card interface pins, and in-system programmable Flash with security fuses.
Technical Context
The 73S1215F-68IM/F implements a single-cycle-per-instruction 80515 core running up to 24 MHz, enabling AES/DES/3-DES and RSA-based PIN encryption. Its integrated USB 2.0 Full-Speed controller supports PC/SC with four endpoints (Control, Interrupt IN, Bulk IN/OUT), each with dedicated FIFOs (16 B / 32 B / 128 B / 128 B).
It embeds a fully autonomous ISO 7816 interface with activation/deactivation sequencers, 6 kV ESD protection, and selectable VCC output (1.8 V / 3.0 V / 5.0 V), plus a hardware-scanned 5×6 keypad with built-in debouncing and scrambling - all coordinated by a unified PLL-driven clock system fed from a 6–12 MHz crystal.

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, USB 2.0 Full-Speed, ISO 7816, but no integrated keypad engine or RTC oscillator input. | Targets higher-security applications requiring larger Flash and ARM toolchain; lacks hardware keypad scanning - requires external GPIO expander or MCU firmware management. | Select when migrating to ARM ecosystem or needing >64 KB code space; accept added firmware complexity for keypad handling. |
| NXP SLN10SE101K1 | ARM Cortex-M0+, 128 KB Flash, USB 2.0, ISO 7816, includes capacitive touch support but no native 5×6 matrix keypad hardware or EMV 4.1 pre-certified stack. | Focused on next-gen touch-enabled readers; lacks Teridian's pre-validated EMV/CCID libraries and hardware PINpad acceleration. | Choose for touch-based HMI or long-term ARM roadmap alignment; expect extended certification effort versus 73S1215F-68IM/F's drop-in EMV readiness. |
Compared with Infineon SLE78CLX2040P and NXP SLN10SE101K1, the 73S1215F-68IM/F uniquely combines EMV 4.1 pre-certification, hardware 5×6 keypad scanning, and integrated RTC oscillator support - making it optimal for cost-sensitive, high-volume USB-connected PINpads requiring minimal firmware development and fastest time-to-certification.

The 73S12xxF product line was engineered specifically for cost-optimized, high-integration smart card reader systems - combining USB, ISO 7816, PINpad, and cryptographic acceleration in a single die to replace multi-chip solutions.
FAQ
What is the primary function of the 73S1215F-68IM/F in smart card reader designs?
The 73S1215F-68IM/F serves as a complete System-on-Chip for smart card readers, integrating an 80515 CPU core, USB 2.0 Full-Speed interface, ISO 7816/EMV 4.1 smart card controller, and hardware 5×6 keypad scanner. It replaces multiple discrete ICs - including microcontroller, USB transceiver, smart card interface, and keypad controller - enabling compact, low-BOM-cost reader implementations. The 73S1215F-68IM/F is widely used in CCID-compliant handheld PINpads and USB reader modules.
Does the 73S1215F-68IM/F support EMV Level 1 and Level 2 certification out of the box?
Yes, the 73S1215F-68IM/F hardware is fully compliant with EMV 4.1 Level 1 (electrical/protocol) requirements, including activation/deactivation sequencing, T=0/T=1 UART handling, and 6 kV ESD protection on card interface pins. Teridian provided pre-validated EMV protocol stacks and reference firmware, enabling faster Level 2 (application-layer) certification. The 73S1215F-68IM/F itself does not perform Level 2 processing - that is implemented in firmware - but its hardware foundation meets all mandatory Level 1 criteria.
What are the power supply requirements for the 73S1215F-68IM/F when operating in USB mode?
When USB functionality is active, the 73S1215F-68IM/F requires VDD_IO and VDD_CORE to be supplied at 3.0–3.6 V, and VDD_USB must be independently powered within the same range. The smart card VCC output (1.8/3.0/5.0 V) is generated internally from a separate 4.75–5.5 V supply. Operating outside these ranges - especially below 3.0 V on VDD_USB - may cause USB enumeration failure or packet corruption. The 73S1215F-68IM/F datasheet specifies strict tolerances in Section 3.2.
Can the 73S1215F-68IM/F operate without an external crystal?
No, the 73S1215F-68IM/F requires an external 6–12 MHz crystal on CLKIN for main system clock generation; its internal PLL depends on this input to derive CPU, USB, and smart card interface clocks. An optional 32.768 kHz crystal may be connected to XTAL32K for RTC functionality, but it is not required for basic operation. The 73S1215F-68IM/F does not support RC oscillators or external clock inputs as substitutes for the primary crystal.
Is the 73S1215F-68IM/F pin-compatible with other members of the 73S12xxF family?
No, the 73S1215F-68IM/F is not pin-compatible with other variants such as the 44-pin QFN version (e.g., 73S1215F-44IM/F). While both share identical functionality and register mapping, their pin counts, layouts, and power/ground pin distributions differ significantly. Migration between packages requires PCB redesign. The 73S1215F-68IM/F specifically uses the 68-pin QFN footprint defined in datasheet Figure 44 and Section 5.1.
