Product details
Overview
TMS320F28377SPZPQ from Texas Instruments is a single-core 32-bit floating-point real-time microcontroller optimized for high-precision closed-loop control in power electronics, motor drives, and EV charging systems. It features a 200MHz C28x CPU with FPU, TMU, VCU-II, and CLA coprocessor; 1MB flash (ECC-protected); 164KB RAM (ECC/parity-protected); four 16-/12-bit ADCs (up to 4.4MSPS aggregate); 24 ePWM channels including 16 HRPWM; dual CAN; USB 2.0; and functional safety certification up to ASIL B/SIL 2.
For engineers reviewing the TMS320F28377SPZPQ datasheet, TMS320F28377SPZPQ pinout, TMS320F28377SPZPQ application, or TMS320F28377SPZPQ equivalent, key selection considerations include its 100-pin HTQFP (PZP) package, –40°C to 125°C free-air temperature rating (Q-grade), AEC Q100 qualification, integrated sigma-delta filter module (SDFM), and CLA-accelerated real-time control for time-critical PWM and protection routines.
Technical Context
The TMS320F28377SPZPQ implements a single-CPU subsystem (C28x + CLA) derived from the dual-core F2837xD family, enabling deterministic execution of control loops at 200MHz while offloading math-intensive tasks like trigonometric transforms (via TMU) and complex filtering (via VCU-II). Its analog subsystem integrates four independent ADCs with hardware post-processing-saturating offset calibration, windowed comparators with DAC references, and trigger-to-sample delay capture-enabling precise current/voltage sensing in isolated shunt-based topologies.
System-level timing and safety are enforced through dual internal 10MHz oscillators, missing-clock detection, windowed watchdog timer, and hardware BIST (HWBIST). The device supports ISO 26262 ASIL B and IEC 61508 SIL 2 functional safety compliance via documented safety mechanisms, ECC-protected memory, and secure boot ROM with dual-zone code security.
