New AVR Microcontroller for Smart Card Reader Applications

Atmel introduce its new AVR microcontroller designed for smart card reader applications. Based on the AVR 8-/16-bit RISC core allowing single cycle instruction execution, the AT90SCR100 embeds 4 Kbytes of EEPROM for data, 4 Kbytes of SRAM and 64 Kbytes of programmable FLASH providing all the flexibility required for fast software upgrade and customization reducing significantly time to market and development costs both during development phase and product life.

The AT90SCR100 offers a comprehensive set of interfaces such as ISO7816 (Class A,B,C supported), USB full Speed 2.0 device and host, USART and TWI to address any applications that interface to synchronous, asynchronous and USB smart cards. In addition, a SPI serial interface plus a dedicated High Speed SPI interface (up to 20Mbps at 20MHz) have been implemented. Respectively combined with an RF front end and/or with a fingerprint sensor, the AT90SCR100 is ideally suited to contactless and/or Biometric reader applications. With its 38 GPIOs in its high pin count configuration (64 pin package), it can also address all USB Keyboards integrating the smart card reader functionality.

Availability and Pricing
Samples for the AT90SCR100 are available now. Packages are available in 32-pin QFN, 64-pin QFN and 64-pin QFP. Volume production will start in May 2009. Prices start at US$ 3.00 for the 64 pin count version and at US$ 1.90 for the 32 pin package in 10,000 quantities.
