The ADSP-CM40xF family of mixed-signal control processors is based on the ARM® Cortex-M4TM processor core with floating-point-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. TheADSP-CM40xF family operates from a single voltage supply(VDD_EXT/VDD_ANA), generating its own internal voltage supplies using internal voltage regulators and an external passtransistor.
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-CM40xF mixed-signalcontrol processors are the platform of choice fornext-generation applications that require RISC programmability, advanced communications and leading-edge signalprocessing in one integrated package. These applications span a wide array of markets including power/motor control, embedded industrial, instrumentation, medical and consumer.
Each ADSP-CM40xF family member contains the followingmodules.
• 8 GP timers with PWM output
• 3-Phase PWM units with up to 4 output pairs per unit
• 2 CAN modules
• 1 two-wire interface (TWI) module
• 3 UARTs
• 1 ADC c...
