C2000 MCUs include key features that effectively improve the performance of sensing and processing systems. In systems with control requirements, customers need accurate sensing of system parameters, low-latency processing of control law equations, and precise generation of drive signals.

These types of features help enable real-time handshaking, data sharing, and debugging. C2000 devices are highly configurable and provide control functions for sensing, processing, actuation, and connectivity.

All C2000 devices include an on-chip analog-to-digital converter (ADC)

• 12-bit single-ended input or 16-bit differential input
• Single ADC with dual sample-and-hold or multiple ADCs with single sample-and-hold
  • Allows sampling operations to be sequenced or synchronized
• Achieve speed conversion from 1MSPS to over 12MSPS

C2000 devices offer SPI and McBSP digital peripherals with direct memory access (DMA) capabilities to connect to external ADCs

• Some applications require a dedicated analog front end or an analog-to-digital converter with specifications beyond what is integrated in the C2000 MCU
• Ability to synchronize external conversions with internal timers

The high-resolution capture (HRCAP) peripheral can measure external pulse widths with typical resolutions in hundreds of picoseconds.

Uses include:

• Capacitive touch applications
• High-resolution period and duty cycle measurement of pulse train cycles
• Instantaneous speed measurement
• Instantaneous frequency measurement
• Voltage measurement across isolation boundaries
• Distance/sonar measurement and scanning

The C2000 looks pretty good.

High-precision analog signals still require dedicated chips. C2000 is indeed very cost-effective for control. The key is that it is much more powerful than other DSCs.
