Selection Guide
| General Description |
|
A7130 is a high performance and low cost 2.4GHz ISM band wireless transceiver. This device integrates both high sensitivity receiver (- 88dBm @4Mbps) and programmable power amplifier (-17 ~ 5dBm). Based on Data Rate Register (39h), user can configure on-air data rates to 4Mbps. A7130 supports fast settling time (90 us) for frequency hopping system. For packet handling, A7130 has built-in separated 64-bytes TX/RX FIFO (could be logically extended to 4K bytes) for data buffering and burst transmission, auto-ack and auto-resend, CRC for error packet filtering, FEC for 1-bit data correction per code word, RSSI for clear channel assessment, thermal sensor for monitoring relative temperature, WOR (Wake on RX) function to support periodically wake up from sleep mode to RX mode and listen for incoming packets without MCU interaction, data whitening for data encryption / decryption. In addition, A7130 has built-in AES128 co-processor (Advanced Encryption Standard) for advanced data encryption and decryption which consists of the transformation of a 128-bit block into an encrypted 128-bit block. Those functions are very easy to use while developing a wireless system. All features are integrated in a small QFN 4X4 20 pins package. A7130’s control registers are accessed via 3-wire or 4-wire SPI interface such as TX/RF FIFO, ID register, RSSI value, frequency hopping to chip calibration procedures. Another one, via SPI as well, is the unique Strobe command, A7130 can be controlled from power saving mode (deep sleep, sleep, idle, standby), PLL mode, TX mode and RX mode. The other connections between A7130 and MCU are GIO1 and GIO2 (multi-function GPIO) to output A7130’s status so that MCU could use either polling or interrupt scheme for radio control. Overall, this device is very easy-to-use for developing a wireless application with a MCU. |
