AMICCOM released a new generation of 2.4GHz wireless voice SOC in October 2025, named A8103. This SoC, available in a 6x6 QFN package, is targeted at wireless voice applications. A8103 integrates the 2.4GHz RF transceiver, with a maximum speed of 2Mbps and a 23dBm high-efficiency output amplifier.
The digital portion integrates a high-performance 1T Pipeline 8051 with 16Kbytes Flash memory, 256bytes internal data SRAM, 1Kbyte external data SRAM, various digital interfaces, and a proprietary audio codec. A 2-wire ICE interface is provided, seamlessly integrating with the Keil C development tool for user development and debugging.
The A8103's RF component inherits the core of AMICCOM wireless RF transceiver. Its receiver sensitivity is -92dBm at 2Mbps and -97dBm at 500kbps. Its programmable RF transmit power range ranges from +13dBm to +23dBm, and the link budget is up to 115dB. The in-house developed 16-bit audio codec provides sampling rate of 8K/16K and 32KSps, allowing for a variety of voice quality options. Amplifiers for microphone and speaker are integrated on-chip, allowing direct connection to the microphone without the need for an external amplifier and capable of driving a 250mW/8ohm speaker.
Customers using the A8103 can use few external components and reduce product size. The digital portion utilizes a high-performance 1T pipeline 8051 core and 24 GPIO pins, which can be used as input buttons to adjust volume or outputs to LEDs to indicate product status. Various digital interfaces, such as I2C, SPI, UART, and PWM, are integrated for use as needed.
AMICCOM provides a proprietary communication protocol library that supports various application scenarios. For example, a wireless voice baby monitor can automatically detect the baby's voice level. When the baby cries, the baby's voice is automatically transmitted to the mother, who can then transmit the sound to comfort the crying child. Another application scenario involves a walkie-talkie mode that supports PTT (push-to-talk) functionality, suitable for use in toys such as wireless walkie-talkies, wireless voice toys, or wireless voice doorbells.
Overall, A8103 is a highly integrated wireless SOC for voice application. It features a high-performance wireless RF core, a built-in audio codec with multiple sampling rates, a fast 8051 CPU core, and a library supporting various application scenarios. All these functions are integrated into a QFN6x6 chip, providing customers with fast, convenient, and low-cost wireless voice solutions.
A8103 are available in a 6mm x 6mm QFN-48 package, and is now available from AMICCOM and its authorized distributors. Welcome to request IC samples and evaluation modules, and start development work. Please contact AMICCOM Electronics for more detail.
