Analog Devices ADSP-CM403BSWZ-FF

ARM Cortex-M4, 100 MHz, 256 kB ROM, 64 kB RAM

The ADSP-CM40x 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 384KB of SRAM memory, 2MB 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-type ADCs and two 12-bit DACs. The ADSP-CM40x 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 lowvoltage design methodology, delivering world class processor and ADC performance with lower power consumption.
