3 Description

The TMS320F280015x (F280015x) is a member of the cost-optimized C2000? real-time microcontroller family

of scalable, ultra-low latency devices designed for efficiency in power electronics.

These include such applications as:

? HVAC compressor module

? Headlight

? DC/DC converter

? Inverter & motor control

? On-board (OBC) & wireless charger

? Pump

? Industrial motor drives

? Motor control

? Digital power

? Sensing and signal processing

TMS320F280015x has dual 32-bit C28x CPUs in Lockstep, enabling the device to achieve ASIL B functional

safety device rating without much SW overhead. The real-time control subsystem is based on TI’s 32-bit C28x

DSP core, which provides 120 MHz of signal-processing performance for floating- or fixed-point code running

from either on-chip flash or SRAM. The C28x CPU is further boosted by the Trigonometric Math Unit (TMU) and

VCRC (Cyclical Redundancy Check) extended instruction sets, speeding up common algorithms key to real-time

control systems.

The F280015x supports up to 256KB (128KW) of flash memory. Up to 36KB (18KW) of on-chip SRAM is also

available to supplement the flash memory.

High-performance analog blocks are integrated on the F280015x real-time microcontroller (MCU) and are closely

coupled with the processing and PWM units to provide optimal real-time signal chain performance. Fourteen

PWM channels enable control of various power stages from a 3-phase inverter to power-factor correction and

other advanced multilevel power topologies.

Interfacing is supported through various industry-standard communication ports (such as PMBUS, SPI, SCI, LIN,

I2C, CAN and CAN FD) and offers multiple pin-muxing options for optimal signal placement.
