Single Chip Solution for Wireless Child Tracking System

The Atmel ATmega256RFR2 is the leading device in this single-chip family, as well as the most efficient device on the market. With the newest device, the family now has an expanded offering range of 64K to 256K of Flash memory, enabling you to easily scale your designs. With the introduction of the advanced hardware-assisted reduced power consumption (RPC) capability, the ATmega RFR2 family now consumes up to 50 percent less current in some operating modes. It allows for 16 MHz operations at as low as 1.8V of supply voltage and fast wake-up time from sleep mode to active modes. A variety of power-down modes, such as a wake-on-radio feature, which keeps the RF transceiver active while the microcontroller sleeps, further enhance efficiency.

The ATmega256RFR2-ZF microcontroller's high data rate modes up to 2Mbit/s are available to support general-purpose 2.4GHz ISM applications. A low-power single-chip design lets you implement the latest battery-driven systems, save board space, and reduce bill of materials (BOM) costs.
