1.3 Description
C2000™ 32-bit microcontrollers are optimized for processing, sensing, and actuation to improve closed-
loop performance in real-time control applications such as industrial motor drives; solar inverters and
digital power; electrical vehicles and transportation; motor control; and sensing and signal processing. The
C2000 line includes the Delfino™ Premium Performance family and the Piccolo™ Entry Performance
The Delfino™ TMS320F2837xS is a powerful 32-bit floating-point microcontroller unit (MCU) designed for
advanced closed-loop control applications such as industrial motor drives; solar inverters and digital
power; electrical vehicles and transportation; and sensing and signal processing. Complete development
packages for digital power and industrial drives are available as part of the powerSUITE and
DesignDRIVE initiatives.
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 time for complex math operations common in
encoded applications.
The F2837xS microcontroller family features a CLA real-time control coprocessor. The CLA is an
independent 32-bit floating-point processor that runs at the same speed as the main CPU. The CLA
responds to peripheral triggers and executes code concurrently with the main C28x CPU. This parallel
processing capability can effectively double the computational performance of a real-time control system.
By using the CLA to service time-critical functions, the main C28x CPU is free to perform other tasks, such
as communications and diagnostics.
The TMS320F2837xS supports up to 1MB (512KW) of onboard flash memory with error correction code
(ECC) and up to 164KB (82KW) 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. The new sigma-delta filter module (SDFM)
works in conjunction with the sigma-delta modulator to enable isolated current shunt measurements. The
Comparator Subsystem (CMPSS) with windowed comparators allows for protection of power stages when
current limit conditions are exceeded or not met. Other analog and control peripherals include DACs,
PWMs, eCAPs, eQEPs, and other peripherals.
