The Atmel AT86ZL3201 Z-Link™ Controller is a low-power CMOS 8-bit microcontroller based on the AVR-enhanced RISC architecture. Similar in function to Atmel's popular ATmega128 and other AVR standard microcontrollers, the Z-Link Controller is custom-ized for systems supporting the new IEEE 802.15.4 standard for Low Rate, Wireless, Personal Area Networks (LR-WPANs) and the emerging ZigBee wireless network pro-tocol based on that standard. The ZigBee Alliance, an association of over 50 companies, is developing ZigBee to ensure interoperability of devices from different manufacturers, to enhance security and supported network topologies, and to estab-lish testing and certification of compliant products.

In addition to many powerful features commonly found on Atmel's AVR microcontrollers AT86ZL3201, the Z-Link Controller includes a 128-bit Advanced Encryption Standard (AES) engine and a NIST-certified random number generator to provide low-cost, low-power network security that conserves program space. With buffered TX and RX ports, two SPI serial interface blocks, 32 general purpose I/O with programmable pull-ups, numerous clock-ing options, and a high-speed clock output, the Z-Link Controller is designed with a flexible interface to support both low-band (868/915 MHz) and high-band (2.4 GHz) radio solutions.

For power conservation, the Z-Link Controller AT86ZL3201 includes two sleep modes, a power-down mode for the ADC, and a programmable brown-out detector. In sleep mode, one 16-bit timer can be running with the extremely low-power 32-kHz oscillator (max. 1uW), and all analog blocks have low-power, standby modes.

The Z-Link Controller AT86ZL3201 includes many features to aide in software development, including a JTAG-compliant interface for on-chip debug and flash programming, and four 16-bit timers.

The 32 KB Flash can be programmed in the system via the built-in bootloader using data directly from either SPI interface or via ROM-code using data from some other source such as RF data (for over-the-air programming). Code security options include the ability to establish a variable-sized, protected section of Flash memory and the abil-ity to lock out JTAG access.The Z-Link Controller AT86ZL3201 will include a proven IEEE 802.15.4 software stack including both the PHY and the MAC protocol layers. In addition, the Z-Link Controller will be sup-ported with a full suite of program and system development tools including C compiler, macro assembler, progam debugger/simulator, in-circuit emulator, and an evaluation kit.
