A7105 A71X05 A71X05AQFI -- 2.4 GHz Short Range Devices
A7105 is a high performance and low cost 2.4GHz ISM band wireless transceiver. This device integrates both high sensitivity receiver (- 95dBm @ 500Kbps) and high efficiency power amplifier (up to 1dBm). In low data rate application, A7105 has special strength for long LOS (line-of-sight) distance because of its ultra-high sensitivity (-107 dBm @ 2Kbps, - 104 dBm @ 25Kbps) with no requirement of external LNA or PA. Based on Data Rate Register (0x0E), user can configure on-air data rates from 2Kbps to 500Kbps.
A7105 supports fast settling time (130 us) for frequency hopping system. For packet handling, A7105 has built-in separated 64-bytes TX/RX FIFO (could be extended to 256 bytes) for data buffering and burst transmission, CRC for error detection, FEC for 1-bit data correction per code word, RSSI for clear channel assessment, data whitening for data encryption / decryption. Those functions are very easy to use while developing a wireless system. All features are integrated in a small QFN 4X4 20 pins package.
A7105’s control registers can be easily accessed via 3-wire or 4-wire SPI bus. For power saving, A7105 supports sleep mode, idle mode, standby mode. For easy-to-use, A7105 has an unique SPI command set called Strobe command that are used to control internal state machine. Based on Strobe commands via SPI bus, MCU can control everything from power saving, TX delivery, RX receiving, channel monitoring, frequency hopping to auto calibrations. In addition, A7105 supports two general purpose I/O pins, GIO1 and GIO2, to inform MCU its status so that MCU could use either polling or interrupt scheme to do radio control. Hence, it is very easy to monitor radio transmission between MCU and A7105 because of its digital interface.
