Product details
Overview
73S1217F-68MR/F/PE from Teridian Semiconductor is a bus-powered 80515-based System-on-Chip for smart card readers, integrating ISO 7816/EMV 4.1-compliant smart card interface, USB 2.0 full-speed (12 Mbps) slave 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 sub-μA OFF mode - enabling handheld E-banking and secure government ID readers.
For engineers reviewing the 73S1217F-68MR/F/PE datasheet, 73S1217F-68MR/F/PE pinout, 73S1217F-68MR/F/PE application, or 73S1217F-68MR/F/PE equivalent, key selection considerations include EMV 4.1 compliance, integrated DC-DC converter with VBUS/VBAT auto-selection, USB PC/SC and CCID readiness, and on-chip RTC with 32 kHz crystal support.
Technical Context
The 73S1217F-68MR/F/PE implements an enhanced 80515 core executing most instructions in one clock cycle, driven by an internal PLL generating multiple system clocks from a 6–12 MHz crystal (plus optional 32 kHz for RTC). Its power architecture supports dual supply sources - USB VBUS (4.4–5.5 V) or battery VBAT (4.0–6.5 V) - with automatic priority and a step-up DC-DC converter requiring only a single 10 μH inductor.
It embeds dedicated FIFOs per interface: 2-byte TX/RX for ISO 7816 UART (T=0/T=1), and configurable USB endpoints (Control: 16 B, Interrupt IN: 32 B, Bulk IN/OUT: 128 B each). The smart card interface includes programmable LDO (1.8/3.0/5.0 V), activation/deactivation sequencers, C4–C8 auxiliary I/O, and 7 kV ESD protection on all interface pins.

FAQ
What is the primary function of the 73S1217F-68MR/F/PE in smart card systems?
The 73S1217F-68MR/F/PE serves as a complete System-on-Chip for contact smart card readers, integrating an 80515 CPU, ISO 7816 interface, USB 2.0 full-speed slave, and hardware PINpad. It handles card activation, T=0/T=1 protocol, PIN entry, encryption, and USB CCID translation - eliminating need for external controllers or interface ICs in devices like E-banking PINpads.
Does the 73S1217F-68MR/F/PE support both USB bus-powered and battery-backed operation?
Yes, the 73S1217F-68MR/F/PE supports dual-supply operation: it automatically selects VBUS (4.4–5.5 V) when present for true bus-powered use, or falls back to VBAT (4.0–6.5 V) for battery backup. Its integrated step-up DC-DC converter operates from either source, and the VPC pin allows single 2.7–6.5 V supply designs - making the 73S1217F-68MR/F/PE flexible across handheld, desktop, and hybrid configurations.
How does the 73S1217F-68MR/F/PE achieve EMV 4.1 compliance?
The 73S1217F-68MR/F/PE achieves EMV 4.1 compliance through on-die implementation of ISO 7816-3 T=0/T=1 UART with hardware sequencers for card activation/deactivation, programmable VCC LDO (1.8/3.0/5.0 V), C4–C8 auxiliary signal support, and 7 kV ESD protection on interface pins. Teridian provided pre-validated firmware libraries and reference designs aligned with EMVCo test plans - enabling direct use of the 73S1217F-68MR/F/PE in certified reader products.
What is the role of the hardware-scanned 5×6 keypad interface in the 73S1217F-68MR/F/PE?
The hardware-scanned 5×6 keypad interface in the 73S1217F-68MR/F/PE performs row/column scanning, mechanical debouncing, and PIN scrambling entirely in silicon - preventing timing-based side-channel attacks. It reduces CPU load, ensures deterministic key response (<5 ms), and removes need for external keypad controllers. This capability is critical for secure PIN entry in E-banking and government ID applications using the 73S1217F-68MR/F/PE.
Can the 73S1217F-68MR/F/PE operate without an external crystal?
No, the 73S1217F-68MR/F/PE requires an external 6–12 MHz crystal for main system clock generation; its internal PLL depends on this input to derive CPU, USB, and peripheral clocks. An optional 32 kHz crystal may be added for RTC functionality, but neither clock source is integrated. The 73S1217F-68MR/F/PE does not support RC oscillators or external clock inputs - crystal dependence is mandatory for timing accuracy and USB/EMV compliance.
