Product details
Overview
AT83C21GC144-ICSIL from Atmel is a smart card interface controller compliant with ISO/IEC 7816-1/2/3/4, EMV 2000, and CB standards. It supports asynchronous T=0/T=1 cards and synchronous/memory cards via command interpreter, delivers 9.6–115 kbps transmission speed, supplies programmable 1.8V/3V/5V card power, and operates across 0°C to +70°C in SSOP24 package - deployed in secure payment terminals and ID authentication devices.
For engineers reviewing the AT83C21GC144-ICSIL datasheet, AT83C21GC144-ICSIL pinout, AT83C21GC144-ICSIL application, or AT83C21GC144-ICSIL equivalent, key selection criteria include ISO 7816 electrical interface compliance, UART host interface configurability (1.2–115.2 kbps), Gemplus Block Protocol (GBP) support, CVCC programmable card voltage, and integrated LED driver capability without external current-limiting resistors.
Technical Context
The AT83C21GC144-ICSIL integrates a dedicated smart card interface engine with on-chip DC/DC converter for card voltage generation (CVCC), supporting 1.8V/3V/5V programmable output. Its UART host interface uses EVCC-referenced level shifters and supports software-configurable baud rates from 1.2 kbps to 115.2 kbps with 8N1 format.
It implements Gemplus Block Protocol (GBP) firmware for host communication and includes hardware-level card presence detection (CPRES), reset control (CRST), clock generation (CCLK), and I/O management (CIO) - all with 4 kV HBM ESD protection on card-side pins and short-circuit current limiting.

FAQ
What smart card standards does the AT83C21GC144-ICSIL support?
The AT83C21GC144-ICSIL supports ISO/IEC 7816-1, -2, -3, and -4, EMV 2000, and CB standards. It handles asynchronous T=0 and T=1 protocols, as well as synchronous and memory cards using a command interpreter. This ensures full interoperability with globally deployed contact smart cards used in payment, ID, and healthcare systems - all verified in the official Atmel datasheet Rev. 4247BS–SCR–05/04.
Does the AT83C21GC144-ICSIL require external components for LED indication?
No, the AT83C21GC144-ICSIL does not require external current-limiting resistors for LED indication. Pins P3.6/CCLK1/LED0 and P3.7/CRST1/LED1 provide direct LED cathode drive with software-selectable output currents of 2 mA, 4 mA, or 10 mA. This feature is confirmed in the Pin Description section and Table 1 of the AT83C21GC144-ICSIL datasheet, enabling simplified board layout and reduced BOM count.
What is the host interface type and configuration range for the AT83C21GC144-ICSIL?
The AT83C21GC144-ICSIL uses a serial asynchronous UART host interface with RxD and TxD pins referenced to EVCC. Baud rate is programmable from 1,200 bps to 115,200 bps, supporting standard 8N1 format (8 data bits, no parity, 1 stop bit). Signal voltage levels are adjustable via EVCC, allowing compatibility with diverse host MCUs - details are specified in the "Host Interface" section of the AT83C21GC144-ICSIL datasheet.
How does the AT83C21GC144-ICSIL manage smart card power supply?
The AT83C21GC144-ICSIL generates programmable smart card supply voltage (CVCC) internally, supporting 1.8V, 3V, and 5V outputs under software control. CVCC is delivered through a dedicated pin and requires only an external decoupling capacitor. This eliminates the need for external LDOs or voltage-switching circuitry - a key differentiator confirmed in the "Chip Power Supply" and "Pin Description" sections of the AT83C21GC144-ICSIL datasheet.
What is the operating temperature range and package type of the AT83C21GC144-ICSIL?
The AT83C21GC144-ICSIL is rated for industrial temperature operation from 0°C to +70°C and is packaged in a 24-pin SSOP (Shrink Small Outline Package) with 0.635 mm lead pitch. This package is JEDEC MO-153 compliant and supports standard SMT reflow processes - information explicitly stated in the "Ordering Information" and "Pin Description" sections of the AT83C21GC144-ICSIL datasheet Rev. 4247BS–SCR–05/04.
