MCUs offer precision feedback with four 16-bit ADCs
Enabling precision feedback in power control applications, the C2000 Delfino 32-bit F2837xS MCUs have been launched by Texas Instruments. Compatible with the recently launched C2000 Delfino F2837xD MCUs, the company claim that the single-core MCUs are the first in the industry to offer four 16-bit ADCs.
The pin- and software-compatibility with the dual-core C2000 Delfino F2837xD MCUs helps expedite development when scaling from higher performance industrial control applications to mid-tier control designs. Developers can utilise existing investments from the F2833x MCUs and transition to the software-compatible F2837xS MCUs, which provide greater CPU performance and more advanced analog and control peripherals. The compatibility also means that the F2837xS and F2837xD MCUs share the same development platform; the Delfino F2837xD Experimenter Kit. The Delfino F2837xD Experimenter Kit is based on the familiar C2000 controlCARD form factor, allowing designers to use this controlCARD with previously released C2000 application kits.
The F2837xS MCUs have a powerful combination of C28x and real-time control accelerator (CLA), providing a combined 400MIPS of floating-point performance, enabling quick and efficient management of multiple control tasks simultaneously. The C28x CPU is further accelerated for trigonometry and complex math operations. An intelligent system partitioning, created by offloading demanding control loop analysis from the main CPU (C28x core) to the CLA, allows the main processor to focus on other tasks such as system diagnostics, applications management or lower frequency control loops.
Developers can save on bill of material costs while maximising system-level integration with other high-integrity analog and control peripherals, including sigma delta demodulators, comparators, DACs and an abundance of control and communication peripherals. The devices can simultaneously process eight sigma-delta modulated channels, each with threshold comparators and a seamless interface to the TI AMC1204 isolated delta-sigma modulator.
The C2000 Delfino F28377S 32-bit MCUs (TMX320F28377S) are now sampling. Different memory and peripheral mixes are also available in the TMS32028376S, TMS320F28375S and TMS320F28374S configurations, which will start at $11.34 USD in 1K unit orders. Developers can evaluate the new Delfino MCUs using the Delfino F2837xD Experimenter Kit docking station (TMDXDOCK28377D) for $219, which includes the modular controlCARD (TMDXCNCD28377D), or purchase the controlCARD separately for $159.
