eCOG1k
The eCOG1k microcontroller is a low-power microcontroller based on a 16-bit Harvard architecture with a 24-bit linear code address space (32Mbyte) and 16-bit linear data address space (128Kbytes). It is available in a 128-pin LQFP package.
A comprehensive Development Kit is available along with a simpler, low cost Evaluation Kit.
The eCOG1kG device is a fully RoHS compliant replacement for the eCOG1k and is functionally identical. Any reference to the eCOG1k in user documentation is applicable to the eCOG1kG.
