New AIoT Reference Designs Support Biometric Access Control

Ambarella, Lumentum, and ON Semiconductor are building on their existing relationship with the release of two new reference designs that will help speed up the development of AIoT devices. The three companies first announced that they were working together back in January, when they unveiled a separate reference design geared toward access control applications.

The new reference design will extend that utility to other verticals like healthcare, smart cities, smart homes, and smart buildings. In each case, the design combines an ON Semiconductor sensor with Lumentum’s VCSEL technology and an Ambarella AI System-on-Chip solution.

The first of the two reference designs is the Vision+, a 4K single-camera solution that can perform depth, AI, and video processing, all on a single chip. It is built with Ambarella’s CV22 CVflow vision processor, Lumentum’s structured light sensing tech, and an 8MP RGB-IR image sensor from ON Semiconductor. The Vision+ is intended for biometric access control systems, and can pick up subjects at a distance of two meters.

The Saturn reference design, on the other hand, runs on an Ambarella CV25 CVflow processor and features ON’s AR0237CS 2MP RGB-IR image sensor and a VCSEL-powered structured light sensing camera. The design can be used in smart door locks in commercial and residential settings, and supports fast-boot video and single-camera video processing.

The three companies have also released a collection of open software development kits that can be configured for more specific 3D sensing applications. The kits are based on Ambarella’s CV2 series, and can come with ToF sensor adapters and an optional 4K RGB-IR image sensor adapter.

The new reference designs are expected to hit the market in June. The Linux SDKs allow developers to integrate third-party applications, and are secured with OTP and Arm TrustZone encryption key technology. Meanwhile, the low-power reference designs will allow manufacturers to deploy the sensor systems in smaller IoT devices. Meticulous has previously predicted that there will be more than 3.8 billion VCSEL units in circulation by 2027.
