• Manufacturer: Melexis Company

6 Detailed Description
The MLX90603 is a System In a Package (SIP) that consists of two silicon dies:
assembled in a wide body (300mils) SOIC16 compatible package.
The MLX90603 is delivered as a fully tested and calibrated device.
The heart of the MLX90603 is the Melexis 16 bit microcontroller: MLX16. It allows software control of:
The microcontroller can access RAM, EEPROM and ROM memories. Also a programmable FLASH
memory is available for development and pre-production series. The standard software library with low-level
routines give access to all IC’s functions. Application examples offer a low-entry level introduction to the
MLX16 programming.
