AMICCOM released a new generation of low current sub1-GHz wireless SOC, named A9129M0. AMICCOM continues to integrate the existing RFICs with MCU and roll-out highly integrated SOC products. The new A9129M0 SOC, like their previous generation products, come from integrating MCU with A7129, which have excellent RF performance and extremely low receiving current. The A9129M0 supports FSK modulation. This chip integrates high performance ARM® Cortex®-M0, built-in 128Kbyte Flash Memory, 16 Kbytes SRAM, 22 GPIOs and various digital interfaces. 2-wire ICE can be developed with Keil C.

The maximum TX Power of A9129M0 is +12dBm, the receiving sensitivity is -118dBm @2 Kbps FSK. The A9129M0 also integrates a DC-DC converter to provide efficient power applications. With input voltage 3.3V for DC-DC converter, A9129M0 RX mode current is 4.16mA, TX mode current is 16mA (+10dBm). It also supports programmable RF output power (-30dBm ~ +12dBm) and programmable data rate (2kbps ~ 2Mbps).

The MCU core of A9129M0 is ARM® Cortex®-M0, which can provide fast computing, user can adjust the MCU speed according to the overall power consumption requirements. A9129M0 has a flexible power management system, the current consumption in deep sleep mode is 110nA and the current consumption in sleep mode with internal timer (32KHz) turned-on is 1.3uA. The A9129M0 has a built-in AES128 co-processor which provides data protection and security. All above features make A9129M0 suitable for various low-power IOT applications. A9129M0 is equipped with a variety of digital interfaces such as UART, I2C, SPI. It has 2 PWM outputs, two 32-bit timers and one 32-bit dual timer. These interfaces share pins with 22 GPIOs, which can be used according to user’s application requirements. A9129M0 is also equipped with 12bit ADC, which provides up to 8 channels for external signal measurement.

Overall, the A9129M0 is a wireless transceiver SOC with high performance and low power consumption. It has excellent RF performance with 12dBm output power amplifier, and supports a variety of digital interfaces and I/O. Especially it’s suitable for applications that are powered by battery and require a long-life cycle. All functions are integrated in the QFN5x5 package.

For AMR application, wireless M-Bus is a communication protocol designed for remote reading of gas, electricity, and water. As global urbanization and resource management become increasingly crucial, the technology to effectively read and manage these resources is of paramount importance. AMICCOM can provide the wireless M-Bus protocol reference codes which support T-mode, S-mode, and C-mode to accelerate customer's development work.
