ATmega644RFR2数据手册RF/IF射频/中频RFID的射频收发器IC规格书PDF

描述 Description

An IEEE 802.15.4 compliant single chip combines an industry-leading AVR microcontroller and best-in-class 2.4GHz RF transceiver. It offers the industry's highest RF performance for single chip devices, with a link budget of 103.5dBm while consuming 50% less current than the existing offerings. The device features hardware assisted multiple PAN address filtering (MAF), improved channel masks on CH25 and CH26 allowing the device to run full power (1W) on these channels using external power amplifiers, wake-on radio, improved link efficiency and reliability using RX override, 32-bit MAC symbol counter, temperature sensor, automatic transmission modes, 128-bit AES crypto engine, true random number generator, high data rate modes, and antenna diversity support.

特性 Features

·Ultra compact size (30.0 × 20.0mm)
