73S1209F-44IM/F

Overview

The 73S1209F-44IM/F is a System-on-Chip device integrating an 80515 CPU core, ISO-7816/EMV smart card interface, and UART bridge. It operates with a digital supply of 2.7V to 3.6V and an analog supply of 4.75V to 6.0V. The IC includes 32KB Flash, 2KB XRAM, and 256B IRAM. It supports 1.8V, 3V, and 5V smart cards via an internal LDO regulator. Communication interfaces include a full-duplex UART (1200bps to 115kbps) and an I2C master interface (400kbps).

Feature Summary

Integrates an 80515 high-performance CPU core capable of up to 24MIPS for encryption processing.
Provides built-in ISO-7816 and EMV 4.1 compliance with hardware activation sequencers.
Includes a 5x6 keypad interface with hardware scanning and debouncing capabilities.
Features an analog voltage input for DC monitoring such as battery level detection.

Applications

UART to ISO-7816 / EMV Bridges
PINpad smart card readers
SIM Readers in Telecom & Personal Wireless devices
Payphones and vending machines

Procurement Notes

Verify the specific package configuration against the datasheet pinout diagrams. Confirm that the required dual power supply voltages are available for the target application design. Ensure firmware compatibility with the embedded Teridian libraries if utilizing turnkey solutions.

Selection Notes

Select this component when a unified solution for smart card reading and host communication is required. The integrated 80515 core reduces external processor requirements. Verify that the 44-pin QFN package fits the mechanical constraints of the final enclosure.

Part Context

Manufactured by Analog Devices Inc./Maxim Integrated, formerly Teridian Semiconductor Corporation. This device belongs to the 73S12xxF series designed for secure access systems. It serves as a bridge between microprocessor-based systems and smart card standards.
