2.0. Features
One standard ICC landing type card acceptor.
One SAM socket
ISO 7816 Parts 1-4 Compliant for Contact Smart Card Interface.
The ACR1251U-C supports contact memory cards (refer to appendix D).
ISO 14443 Parts 1-4 Compliant for Contactless Smart Card Interface.
A built-in antenna for PICC contactless access applications.
The ACR1251U-C supports the following Tag Types:
o MIFARE Classic. E.g. MIFARE 1K, 4K, MINI and Ultralight.
o ISO14443-4 Type A and B.
o ISO18092 FeliCa, NFC tag
T=CL emulation for MIFare 1K/4K PICCs
High Speed (424 kbps) Communication for PICCs. #Maximum 848 kbps.
Energy saving modes for turning off the antenna field whenever the PICC is inactive,
or no PICC is found. It prevents the PICC from exposing to the field all the time.
User-Controllable Peripherals. E.g. LED, Buzzer.
PCSC Compliant for Contact and Contactless Interfaces.
USB V2.0 Interface. (12M bps)
Device Firmware Upgradeable through the USB Interface.

3.0. Architecture
AT90SCR is for main processor for communication with PC, and control the contactless chip,
communication with ICC contact card and
perform the communication between contactless tags and
peripherals. PN512 act as a contactless chip to
AT90SCR
For communication architecture, the protocol between ACR1251U-C and PC is using CCID protocol.
All the communication between ICC and PICC are PCSC
Compliant
PICC and ICC are working exclusively, when ICC inserted, PICC will be disabled.
