Analog Devices ADSP-CM40x 240 MHz mixed signal development boards

Mouser Electronics has available evaluation boards for the Analog Devices high-performance ADSP CM40x mixed signal-control processor family. The processor is based on the 32-bit ARM Cortex M4 core, a superset of the Cortex M3 embedded processor core.

The core builds on the M3 by adding digital signal processing (DSP) extensions that include both 16- and 32-bit single-cycle multiply accumulate (MAC), a single-cycle dual MAC, single-cycle signed and unsigned multiply instructions and a hardware divide. It also supports SIMD arithmetic, allowing multiple operations in one clock cycle. The core includes 16 kB of L1 instruction cache and an IEEE 754 compliant single-precision floating point unit (FPU).

The mixed signal processor runs at 240 MHz and includes up to 2 MB Flash memory and 384 KB of parity-enabled SRAM. On-chip peripherals include USB OTG, ethernet and CAN 2.0B. The chip boasts high-performance, high-accuracy analog peripherals including dual 16-bit ADCs with 380 ns conversion time, and dual 12-bit DACs supporting a 50 kHz output rate. A selection of on-chip timers, digital I/O and serial ports complement the CM40x’s range of functionality.

The ADSP CM40x EZ-Board allows easy evaluation and prototyping of a CM40x-based product by providing access to all CM40x analog and digital peripherals. The board targets motor control and data acquisition applications. All networking ports are available and there is also a port for an external 2x20 LCD. The ADSP CM40x EZ-KIT Lite comes with the EZ-Board plus a Segger J Link Lite ARM debug probe. Expansion boards allow developers to directly probe any port on the CM40x processor.
