In the visual IoT market, various innovative application products are constantly emerging and maintaining stable growth. A segmented low-power visual category has been developed in traditional security visual monitoring applications, and product forms continue to emerge, such as smart doorbells, baby caretakers, smart bird feeders, hunting cameras, pet cameras, etc. In addition, popular products such as AI smart wearable glasses and AI multi model perception interactive toys that have emerged in the past six months have also begun to integrate visual modules. This trend has raised higher requirements for underlying chip solutions: devices need to achieve front-end high-definition visual processing, stable networking capabilities, and fast response capabilities for multimodal interaction with cloud AI under low-power conditions, while also considering lightweight and cost controllability.

In response to the urgent needs of market customers in this field, the all-new V821 series has emerged. V821 has not only completed mass production on typical security visual products, but has also expanded to various markets such as smart wearables, and multiple products have been fully implemented.

V821 highlights - eight abilities, combined into one

Processing capability

The dual RISC-V architecture supports a maximum main core frequency of 1.2GHz and a maximum small core frequency of 600MHz. The dual core heterogeneous design can meet various power consumption scenarios such as full speed operation, low-speed AOV operation, WIFI active sleep, hibernation level standby, etc. It can achieve millisecond level system cold start image and video capture, and the computing power performance can support end-to-end image processing algorithms such as human shape detection, face detection, and face recognition.

Visual ability

Supports dual camera direct access and supports multi camera/multi-resolution expansion. A single camera can support up to 8M image sensors, meeting the end-to-end upload requirements of current and future multimodal models for various image clarity.

Video capability

Support maximum 2K@30fps / 1080P@60fps Professional grade H.264 format, 8M MJPEG format hardware encoding, and support for MJPEG and H.264 decoding, can meet the requirements of low bandwidth and low latency for cloud video related services.

Audio capability

Support high-definition voice input, combined with various audio front-end algorithms, to meet the low latency real-time interaction needs between the end side and the cloud.

Display capability

Supports multiple screen display solutions such as RGB screens with a maximum size of 800 * 480 and dual SPI screens, meeting various functions such as touch interaction, facial expression interaction, and audio and video material display for products.

Action ability

It can perform microsecond level control processing based on the built-in RISC-V small core and RTOS, with multiple built-in PWM interfaces to meet the needs of multi motor control.

Storage Capacity

Supports storage media such as SPI NOR/SPI NAND/SD NAND/eMMC, and can be used in combination (such as SPI NOR+SD NAND, etc.) to meet the storage expansion needs of various visual products and multimodal contextual memory products.

Connectivity

Built in 2.4G Wi Fi connectivity, allowing for seamless video connection up to 100 meters outdoors.

(* Supports Wi Fi& The PintoPin version of Bluetooth is ready to go

V821 achieves the above eight capabilities simultaneously through a highly integrated chip, with a package size of only 9mm * 9mm, enabling extremely small hardware. Paired with the development product package, V821 can meet the rapid mass production needs of application solutions, and can also be further expanded with peripheral products to achieve more innovative products.
