1. DESCRIPTION

The ADSP-CM408CSWZ-AF family of mixed-signal control processors is based on the ARM® Cortex-M4TM processor core with floatingpoint unit operating at frequencies up to 240 MHz and integrating up to 384 kB of SRAM memory, 2 MB of flash memory, accelerators and peripherals optimized for motor control and photo-voltaic (PV) inverter control and an analog module consisting of two 16-bit SAR ADCs and two 12-bit DACs. The ADSP-CM408CSWZ-AF family operates from a single voltage supply (VDD_EXT/VDD_ANA), generating its own internal voltage supplies using internal voltage regulators and an external pass transistor. This family of mixed-signal control processors offers low static power consumption and is produced with a low power and low voltage design methodology, delivering world class processor and ADC performance with lower power consumption. By integrating a rich set of industry-leading system peripherals and memory , the ADSP-CM408CSWZ-AF mixed-signal control processors are the platform of choice for next-generation applications that require RISC programmability, advanced communications and leading-edge signal processing in one integrated package.
