Atmel has introduced a microcontroller with an RFID reader block for LF Amplitude Shift Keying (ASK) RFID readers and programmers for access control, industrial automation and animal identification applications.
This is claimed to be the first MCU with full LF RFID reader functionality within a single package. Traditonally, the MCU and RFID reader are located in two different packages.
It is available in a 5mm x 7mm QFN package and operating in the low-frequency (LF) range at 100-150kHz.
The ATA5505 makes building a complete reader an easy process requiring just a few external components and an antenna coil. Using the new device eliminates the need for expensive discrete components such as crystals, which are currently required with competitors' 2-chip RFID solutions.
The Atmel AVR MCU has 16kbyte of in-system self-programmable flash, 512byte SRAM and 512byte EEPROM.
There are 16 general-purpose I/O lines, 32 general-purpose working registers, one 8-bit timer/counter with compare modes, one 8-bit high-speed timer/counter, a universal serial interface (USI), a LIN controller, internal and external interrupts, a 11-channel 10-bit A/D converter and programmable watchdog timer with internal oscillator.
By executing instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed.
Samples are available.
