Description
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 onboard flash memory with error correction code (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.
Peripherals such as dual EMIFs, dual Controller Area Network (CAN) modules (ISO11898-1/CAN 2.0B-
compliant), and a new uPP extend the connectivity of the F2837xS. The uPP is a new feature to the
C2000 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 universal serial bus (USB)
connectivity to their application.
