1. Description
Smart Cards and Smart Card Readers are increasingly being used in various systems such as Health Care, USB Token, Password Generator, Access control, Laptop Computer, Set Topbox, Payment Terminals... These applications require complex integration using different communicating interfaces. The AT90SCR100 based on the powerful 8/16bit AVR(R) Core technology, meets the requirements of such applications thanks to its embedded communication interfaces: USB Full-speed, ISO7816 (1-4,12) interface, High Speed SPI supporting speed up to 20Mbps, USART, TWI. The AT90SCR100 has been designed to support standard systems such as Contactless interface and Fingerchip, among others. An AES engine is also embedded to ease the development of secured communication between AT90SCR100 and external peripherals. All these features require a minimum of external components which makes this solution the best choice for low cost high integration in small environments. Its FLASH memory allows remote firmware management. The JTAG interface eases code development, and program loading in end-customers factories. A low pincount package is also available for embedded application with size constraints, such as USB tokens, laptop computers. A complete datasheet will soon be available on Atmel's website: www.atmel.com.

3. Pin List Configuration
* 2 package configurations to answer different needs
- 32pins: LowPinCount package: for small package size, useful for small embedded systems (AT90SCR100L and AT90SCR100LS) - 64pins: FullPinCount: For full performance advanced reader (AT90SCR100H)
!
Caution
On Full Pin Count (FPC) package, the only supported package type is QFN, and we connect all the Vss signals to the e-pad. It is important to have it fully soldered on groundplane of final PCB. * USBReg refers to 3.3V USB specific regulator
Note
* PCINTx refer to Pin Change Interrupts. See "External Interrupt Registers" in full Datasheet. Take care of the multiplexed functionnalities of each port. All functionnalities may be active at the same time. The only way to disable a feature is to deactive it inside the corresponding peripheral blokck.

3.1.1 Recommendations 1. In Order to reduce the board parasitics, the external components for DCDC converter should be as close as possible to the chip pins (ideally solded directly on the pins). 2. In order to have a correct current limitation, the board parasitic resistances must be taken into account in the choice of the Rs value (e.g., if each metal line connecting Rs to the chip adds a 10 m resistance, the correct Rs value should be 200-2x10=180m) 3. CVcc and CVss lines must have very low resistance (short and wide metal line). 4. R1, R2, R3 and R4 must be placed as close as possible to the chip pins. 5. Connect e-pad to ground. If possible connect it to ground plane
