The TMS320F2807x microcontroller platform is part of the Piccolo™ family and is suited for advanced closed-loop control applications
inverters and digital power;
vehicles and transportation; and
and signal processing. Complete development packages for digital power and industrial
drives are available as part of the powerSUITE and
The F2807x is a 32-bit floating-point microcontroller based on TI’s industry-leading
C28x core. This core is boosted by the trigonometric hardware accelerator which improves
performance of trigonometric-based algorithms with CPU instructions such as sine, cosine, and
arctangent functions, which are common in torque-loop and position calculations.
The F2807x 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 F2807x device supports up to 512KB (256KW) of ECC-protected onboard flash memory
and up to 100KB (50KW) of SRAM with parity. Two independent security zones are also available for
128-bit code protection of the main C28x.
The analog subsystem boasts up to three 12-bit ADCs, which enable simultaneous
management of three independent power phases, and up to eight windowed comparator subsystems
(CMPSSs), allowing very fast, direct trip of the PWMs in overvoltage or overcurrent conditions. In
addition, the device has three 12-bit DACs, and precision control peripherals such as enhanced
pulse width modulators (ePWMs) with fault protection, eQEP peripherals, and eCAP units.
Connectivity peripherals such as dual Controller Area Network (CAN) modules
(ISO 11898-1/CAN 2.0B-compliant) and a USB 2.0 port with MAC and
full-speed PHY let users add universal serial bus (USB) connectivity to their application.
