Selection Guide
| General Description |
|
A9139 is a high performance and low cost Sub1GHz ISM band system-on-chip (SoC) wireless transceiver. This device integrates high speed pipeline 8051 MCU, 16KBytes In-system programmable flash memory, 4KB SRAM, various powerful functions and excellent performance of Sub1GHz GFSK/FSK transceiver. A9139 has various operating modes, making it highly suited for systems where ultra-low power consumption is required. A9139 has an 8bit ADC for RSSI and 8 channel 12bit ADC for general purpose. Three kinds of serial communication port (SPI, I2C and UART) can interact with other device(s). A9139 is one of AMICCOM sub1GHz family. It integrates AMICCOM sub1GHz transceiver well and offers a low cost solution with advanced radio features such as high output power amplifier up to 19 dBm (433MHz band, excluding LPF and HPF) and low noise receiver (-111dBm @50Kbps). Therefore, A9139 is very suitable for long LOS (line-of-sight) applications without the need to add an external LNA or PA. The on-chip data rate divider supports programmable on-air data rates from 2K to 250Kbps to satisfy different system requirements. For a battery powered system, A9139 supports fast settling time to reduce average power consumption. |
