TMS320F28377SZWTT Overview
A microcontroller (MCU) is a compact integrated circuit designed to govern a specific operation in an embedded system. It contains a processor core, memory, and programmable input/output peripherals. The C2000 family is a specialized line of MCUs optimized for real-time control, combining the processing power of a digital signal processor (DSP) with the ease of use of a microcontroller. This makes them suitable for applications requiring high-speed, precise control loops, such as motor drives, power conversion, and renewable energy systems.
Key features include a 32-bit CPU with FPU and TMU, a CLA that offloads control tasks from the main CPU, and a 16-bit ADC with up to 12-bit resolution. The device supports functional safety (FuSa) applications, with features like a memory protection unit and error correction code (ECC) on flash. It operates over a temperature range of -40°C to 105°C, ensuring reliability in harsh environments. The NFBGA package offers excellent thermal performance and compact footprint, suitable for space-constrained designs.
The architecture of the TMS320F28377S is designed for deterministic execution of control algorithms. The CLA is a parallel processor that can execute independent control loops simultaneously with the main CPU, effectively doubling throughput for time-critical tasks. The TMU accelerates trigonometric calculations, reducing the cycle count for complex math operations. The device also includes a programmable control law accelerator, which is a dedicated hardware block for implementing control laws without CPU intervention.
Typical applications include industrial motor drives, solar inverters, digital power supplies, and automotive powertrain control. The high MIPS rating and integrated peripherals make it suitable for multi-axis servo control and advanced power conversion topologies. The device's ability to handle complex algorithms in real time is critical for these applications.
When designing with this MCU, ensure proper decoupling of the 1.2V core and 3.3V I/O supplies, and follow the layout guidelines in the datasheet for the ADC and high-speed interfaces. The device requires a stable clock source, and the internal oscillator can be used for cost-sensitive designs.

Design Notes
The TMS320F28377SZWTT requires separate 1.2V core and 3.3V I/O supplies. Use low-ESR ceramic capacitors (100nF and 10uF) close to each power pin. For the core supply, a dedicated LDO or DC-DC converter with adequate current capability is recommended. Ensure proper decoupling to prevent noise-induced errors in ADC and high-speed interfaces.
Follow the layout guidelines in the TI datasheet for the 337-pin NFBGA package. Route high-speed signals (e.g., EMIF, ADC inputs) with controlled impedance and minimize trace lengths. Place the crystal oscillator close to the X1/X2 pins and keep the ground plane continuous under the device. Use vias for thermal relief to the exposed pad.
Avoid exceeding the absolute maximum ratings for supply voltages. Ensure the boot mode pins are configured correctly for the desired boot source. For functional safety applications, implement the recommended self-test routines and use the ECC features on flash. Verify the ADC reference voltage and input scaling to avoid measurement errors.
