UNISOC has launched a new processor for AIoT (Artificial Intelligence + IoT) applications with V5663 dual-core Cortex-M33 processor, supports for dual-band WiFi 5, Bluetooth 5.1, and audio features such as a voice activity detector and microphone array support which should make it ideal for smart speakers, and other smart audio applications.
- Arm Cortex-M33 processor @ 442 MHz with TrustZone, 32KB I-cache, 32KB D-Cache for application code
- Arm Cortex-M33 processor @ 416 MHz for WiFI and Bluetooth
- Memory – Built-in SRAM + external PSRAM interface
- Storage – eMMC, SDXC interfaces
- Connectivity –
- Audio – Voice Activity Detector (VAD), PDM and I2S/PCM interfaces
- USB 2.0 / 3.0, eMMC
- I2C, SPI, HS SPI, UART
- GPIO, PWM
- Touch and push-button interfaces
- Aux ADC
- Debugging – JTAG
- Security – Crypto Acceleration, eFuse, ARM PSA security architecture certification: PSA Level 1, on-going PSA Level 2
- Manufacturing – 22nm process
The company also designed a V5663 evaluation/development board with five antennas, two built-in microphones, a speaker connector, a USB-C interface, and an SPI LCD interface, plus some touch buttons. Power appears to be delivered either through a 12V DC jack or external 4V battery.
UNISOC also worked on AILIGO development framework for the processor/board and will launch a community in the next few weeks. The framework is based on an RTOS (FreeRTOS?) with a communication stack, audio library and driver, power management. and so on.
The diagram above also reveals several Bluetooth and WiFi sample code/demos will be part of the SDK. Somehow the audio libraries are optional, so they may charge extra for those, and it also looks like only select components will be open source.
There’s no product page that I could find at this stage. It’s not the first WiFi 5 + Bluetooth 5 processor from the company, as we previously covered IVY5661 board following 96Boards IoT Edition specifications.
