TI TMS320F28377DPTPT Dual-Core C2000 Real-Time MCU

The TMS320F28377DPTPT is the dual-core member of the Texas Instruments C2000 F2837xD family: two 200 MHz C28x floating-point CPUs, each with its own Control Law Accelerator, in a 176-pin HLQFP package. TI rates the device at 800 MIPS. It is aimed at high-end inverter, servo and power-conversion controllers where one core can handle speed and position while the second runs the current and torque loops.

Technical specifications

Choosing between the F2837xD devices

The F2837xD datasheet covers eight devices, and the three-digit number and suffix change what is on the chip. Within the family, flash is either 512 KB or 1 MB and total RAM is either 172 KB or 204 KB depending on the device, and some members offer 12-bit ADC operation only, so a replacement must carry the same three-digit number as the original part. The PTP suffix means the 176-pin HLQFP; the ZWT suffix is a 337-ball BGA and PZP is a 100-pin HTQFP, none of which fit the same land pattern. The last letter T is the 105 degC junction grade, S is 125 degC and Q is the automotive-qualified grade.

Typical uses

TI lists traction and servo drive control, central and string inverters, energy storage power conversion systems, EV charging modules, three-phase UPS, large commercial HVAC motor control and CNC control among the applications. The device supports functional-safety designs: TI documents hardware integrity up to SIL 2 and offers documentation toward IEC 61508 SIL 3 system design. Where a single-core floating-point controller is enough, the TI TMS320F28335PGFA digital signal controller is the simpler choice; more controller and data acquisition parts are listed under controllers and data acquisition.

How the TMS320F28377DPTPT works

The TMS320F28377DPTPT is a real-time microcontroller with two 32-bit C28x processor cores, each running at 200 MHz with a floating-point unit. Each core has its own Control Law Accelerator, which runs control loops on its own and leaves the main core free. Fast analog-to-digital converters sample the signals, high-resolution PWM channels drive the power stage, and the cores share flash and RAM. Because the two cores run at once, one can handle speed and position while the other runs the current loop.

Where the TMS320F28377DPTPT is used

• Industrial servo drives
• Solar and power inverters
• Motor control for pumps and compressors
• Power conversion and charger controllers
• Equipment that needs a fast control loop

Installation, commissioning and maintenance notes

Check that the board land pattern matches the 176-pin HLQFP, 24 x 24 mm body. Supply the core at 1.2 V and the I/O at 3.3 V, and follow the power-up order in the device documentation. Decouple each supply pin close to the chip and keep analog and digital grounds clean. Store the parts in dry packaging until they are soldered, as the maker advises for moisture-sensitive packages.

Keep the date code, the lot number and the order reference with the purchasing file.

Choosing the right TMS320F28377DPTPT part

A replacement must carry the same three-digit number and the same package suffix as the original part, because other family members differ in flash, RAM and pin count.
