AS7265x Multispectral Sensor Reference Design
Reference design for the AS7265x multispectral sensor chipset (AS72651, AS72652, AS72653). Includes USB power management, Li-ion charging, and 4Mb SPI Flash memory.
Overview
This document provides a detailed hardware reference design for the ams AS7265x multispectral sensor suite, which includes the AS72651, AS72652, and AS72653 sensors to provide 18 spectral channels. The design incorporates an Adesto AT25SF041 SPI Flash for firmware storage and a Linear Technology LTC4067 for USB power management and Lithium-ion battery charging. The circuit supports both I2C and UART communication modes and utilizes an AS1364 LDO to provide a regulated 3.3V supply. Schematic diagrams illustrate the sensor interconnects, LED drive circuitry, and programming headers.
Use Cases
- Portable multispectral analysis
- Color measurement and light matching
- Material identification and counterfeit detection
- Agricultural monitoring and crop health analysis
- Mobile spectral sensing applications
