73S1217F-68M/F/PE

Overview

The 73S1217F is a bus-powered 80515 System-on-Chip designed for smart card reader applications. It integrates an ISO-7816/EMV interface, USB 2.0 full-speed slave interface (12Mbps), and a 5x6 PINpad interface. The device features a high-performance 80515 core operating up to 24MHz with 64KB Flash, 2KB XRAM, and 256B IRAM. Power management includes an inductor-based DC-DC converter supporting VBUS (4.4V–6.5V) or VBAT (4.0V–6.5V), with automated detection prioritizing VBUS. An OFF mode draws less than 1μA.

Feature Summary

• Integrates ISO-7816/EMV compliant smart card interface with LDO regulator and auxiliary I/O lines.
• Includes USB 2.0 full-speed interface with dedicated FIFOs for control, interrupt, and bulk transfers.
• Features an on-chip DC-DC converter enabling operation from either USB bus power or battery supply.
• Provides hardware keypad scanning with debouncing and scrambling capabilities.

Applications

• Hand-held PINpad smart card readers
• Transparent USB card readers
• USB keys

Following the acquisition of Maxim Integrated by Analog Devices, these products are managed under the ADI portfolio. The 73S1217F specifically targets high-volume PINpad reader applications by combining multiple communication protocols into one CMOS SoC.

Replacement Considerations

Consult official Analog Devices documentation for confirmed substitute part numbers. Verify functional equivalence regarding pinout, memory configuration, and supported interfaces before considering alternatives.

FAQ

How does the 73S1217F handle power source selection?

The chip automatically detects voltage presence and prioritizes VBUS over VBAT. If VBUS is present, it powers up the DC-DC converter using VBUS; otherwise, it uses VBAT.

What encryption capabilities does the CPU core support?

The 80515 core provides up to 20MIPS processing power, meeting requirements for AES, DES/3-DES, and RSA encryption algorithms.

Is the embedded Flash memory programmable in-circuit?

Yes, the embedded Flash memory is in-system programmable and lockable by means of on-silicon fuses.
