Texas Instruments (TI) launches the new C2000 Delfino 32-bit F2837xS microcontrollers (MCUs). These single-core MCUs are the first in the industry to offer four 16-bit analog-to-digital converters (ADCs), enabling precision feedback in power control applications.
The Delfino TMS320F2837xS is a powerful 32-bit floating-point microcontroller unit (MCU) that lets designers consolidate control architectures and eliminate multiprocessor use in high-end systems.
The real-time control subsystem is based on TI’s 32-bit C28x floating-point CPU, which provides 200 MHz of signal processing performance. The C28x CPU is further boosted by the new TMU accelerator, which enables fast execution of algorithms with trigonometric operations common in transforms and torque loop calculations; and the VCU accelerator, which reduces the latency for complex math operations common in encoded applications.
The F2837xS features a real-time control accelerator, also known as CLA. The CLA provides an additional floating-point accelerator used to run parallel time-critical control algorithms, providing bandwidth for the C28x to focus on system tasks.
The TMS320F2837xS supports up to 1MB of on-board flash memory with ECC and up to 164KB of SRAM. Two 128-bit secure zones are also available on the CPU for code protection.
Performance analog and control peripherals are also integrated on the F2837xS MCU to further enable system consolidation. Four independent 16-bit ADCs provide precise and efficient management of multiple analog signals, which ultimately boosts system throughput. New sigma-delta peripherals enable isolated current shunt measurements and windowed comparators allow protection of power stage when current limit conditions are exceeded or not met. Other analog and control peripherals include DACs, PWMs, eCAPs, eQEPs, and other peripherals.
Connectivity peripherals such as dual EMIFs, dual CAN 2.0 interfaces, and a new uPP extend the performance of the F2837xS. The uPP is a new feature to the TMS320C2000 MCUs and supports high-speed parallel connection to FPGAs or other processors with similar uPP interfaces. Lastly, a USB 2.0 host port with MAC and PHY lets users easily add USB connectivity to their application.
