ADI 公司的ADSP-CM403F是{方案}ARM® Cortex－M4TM内核的具有浮点运算的处理器,工作频率高达240MHz,集成了高达384KB的SRAM存储器,2MB闪存,两个16位SAR范例的ADC和两个12位DAC,加快器和外设.器件工作于单一电压,主要用于马达控制和光伏电压(PV)逆变器控制.本京电港论坛文章先容了ADSP-CM403F主要特点,框架图,模拟子系统框架图以及ADSP-CM403F EZ-KIT Lite评估板主要特点,电路原理图纸和质料清单.

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. 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 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 (shown in Table 1), the ADSP-CM40x 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. These applications span a wide array of markets including power/motor control, embedded industrial, instrumentation, medical and consumer.

Each ADSP-CM40x family member contains the following modules.

• 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

The processors contain two ADCs and two DACs. Control of these data converters is simplified by a powerful on-chip analog-to-digital conversion controller (ADCC) and a digital-to-analog conversion controller (DACC). The ADCC and DACC are integrated seamlessly into the software programming model, and they efficiently manage the configuration and real-time operation of the ADCs and DACs.

The ADSP-CM403F processor is based on the ARM® Cortex®-M4 processor　core and is designed for photovoltaic applications. The EZ-KIT Lite is shipped with all of the necessary hardware―you can start the evaluation immediately. The package contains the standalone evaluation board and CE-approved power supply. The EZ-KIT Lite version ships with the J-Link Lite ARM, while the EZ-Board® version requires the customer to provide a debugger.
