AT83C21GC144-ICSIL

Specialized Overview

The AT83C21GC144-ICSIL is a smart card interface controller designed for ISO/IEC 7816-1, 2, 3, and 4 compliance. It supports asynchronous T=0/T=1 cards and synchronous memory cards with command interpreters. The device manages electrical interfaces including 1.8V, 3V, and 5V card power supplies, with transmission speeds from 9.6 Kbps to 115 Kbps. Host communication occurs via a serial asynchronous link at 1,200 bps to 115,200 bps using the Gemplus Block Protocol (GBP). Operating voltage ranges from 2.85V to 5.4V, with typical consumption of 8 mA and maximum of 150 mA when smart card powered. It features 4 kV ESD protection on card pins and operates within an industrial temperature range of -40°C to +85°C in a 24-pin SSOP package.

Specialized Procurement Notes

Verify the specific firmware version indicated by the 'xxx' suffix in the part number against project requirements before ordering. Confirm that the SSOP24 stick packing format aligns with assembly capabilities. Ensure the industrial temperature rating meets environmental specifications. Cross-reference the manufacturer history as Atmel products are now managed under Microchip Technology.

Specialized Selection Notes

Select this component for applications requiring dedicated hardware management of smart card electrical interfaces and protocol handling. Consider the GBP library availability for software integration. Evaluate power consumption constraints, noting the 150 mA maximum draw during smart card operation. Verify compatibility with host processor UART capabilities for the serial asynchronous link.
