Product details
Overview
TMS320F28377SPZPT from Texas Instruments is a 32-bit floating-point real-time microcontroller featuring a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), Viterbi/Complex Math Unit (VCU-II), and a parallel 200MHz Control Law Accelerator (CLA). It integrates four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 high-resolution HRPWM outputs, dual CAN 2.0B modules, USB 2.0 (MAC+PHY), and 169 GPIOs - deployed in industrial motor drives, solar inverters, and EV charging power modules.
For engineers reviewing the TMS320F28377SPZPT datasheet, TMS320F28377SPZPT pinout, TMS320F28377SPZPT application, or TMS320F28377SPZPT equivalent, key selection considerations include its single-CPU/CLA subsystem architecture, 1MB flash + 164KB RAM (ECC-protected), nFBGA-337 package with 16×16mm footprint, functional safety compliance up to ASIL B/SIL 2, and support for isolated current sensing via SDFM and comparator subsystem.
Technical Context
The TMS320F28377SPZPT implements a deterministic real-time control architecture where the CLA executes time-critical control loops (e.g., current/voltage regulation) independently of the main C28x CPU, enabling concurrent processing without interrupt latency penalties. Its analog subsystem includes hardware-accelerated ADC post-processing (offset calibration, setpoint error, windowed compare with DAC references) and eight SDFM input channels for sigma-delta modulator interfacing.
System-level timing relies on dual zero-pin 10MHz oscillators, an on-chip crystal oscillator, and PLL-based clock generation supporting multiple low-power modes with external wakeup. Peripheral connectivity includes two EMIFs (ASRAM/SDRAM), six-channel DMA, four SCI/UARTs, three SPIs, two I²C, two McBSPs, and a 12-pin uPP interface for FPGA co-processing - all mapped to 169 multiplexed GPIOs with input filtering.

FAQ
What is the maximum operating junction temperature for the TMS320F28377SPZPT?
The TMS320F28377SPZPT is rated for industrial temperature operation with a maximum junction temperature of +125°C. This rating is confirmed in the device's Recommended Operating Conditions table and applies across the full voltage and frequency range. The part uses the 'S' temperature grade designation, distinguishing it from the 'T' grade (105°C) and automotive 'Q' grade (150°C). Thermal design must maintain TJ ≤ 125°C under worst-case power dissipation conditions.
Does the TMS320F28377SPZPT support pin-to-pin compatibility with other F2837xS devices?
Yes, the TMS320F28377SPZPT is pin-to-pin compatible with other F2837xS family members in the same package variant - including TMS320F28379S, TMS320F28378S, and TMS320F28376S in the 337-ball ZWT nFBGA. This compatibility extends to power, ground, GPIO, peripheral, and debug pins. However, peripheral availability (e.g., number of ADCs or ePWMs) may differ between variants, so firmware must be validated against the specific device's resource map.
How many high-resolution PWM channels does the TMS320F28377SPZPT provide?
The TMS320F28377SPZPT provides 16 high-resolution PWM (HRPWM) channels, implemented across eight ePWM modules where both A and B outputs support sub-nanosecond resolution. These channels are fully independent and support dead-band generation, phase shifting, and trip-zone protection - critical for advanced topologies like SiC/GaN-based inverters requiring precise gate timing and fast fault response.
Is the TMS320F28377SPZPT qualified for functional safety standards?
Yes, the TMS320F28377SPZPT is certified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD. Its hardware integrity meets ASIL B/SIL 2 requirements, and TI provides functional safety documentation (FMEDA, safety manual, diagnostic software library) to support system-level certification. Safety features include ECC memory, HWBIST, windowed watchdog, and lockstep-capable peripherals - all documented in the SPRS881K datasheet.
What development tools are recommended for the TMS320F28377SPZPT?
Texas Instruments recommends the LAUNCHXL-F28379D LaunchPad development kit and C2000Ware software suite for initial evaluation and firmware development of the TMS320F28377SPZPT. For production-grade debugging, the XDS200 or XDS110 emulators with Code Composer Studio v12+ are supported. TI also provides MotorControl SDK and DigitalPower SDK - both pre-validated for F2837xS devices and containing libraries for FOC, PID, and digital power control loops.
