Texas Instruments TMS320F28377SPTPS

Overview

TMS320F28377SPTPS from Texas Instruments is a 32-bit floating-point real-time microcontroller featuring a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II), with 1MB flash, 164KB RAM, dual-zone security, and functional safety certification up to ASIL B/SIL 2 - deployed in EV traction inverters, solar string inverters, and industrial motor drives.

For engineers reviewing the TMS320F28377SPTPS datasheet, TMS320F28377SPTPS pinout, TMS320F28377SPTPS application, or TMS320F28377SPTPS equivalent, key selection considerations include its single-CPU/CLA architecture, 176-pin HLQFP package, 16-bit/12-bit dual-mode ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 HRPWM, and ISO 11898-1 CAN compliance for high-reliability closed-loop control systems.

Technical Context

The TMS320F28377SPTPS implements a single-core C28x + CLA subsystem architecture (vs. dual-core F2837xD), where the 200MHz CLA executes time-critical control loops independently of the main CPU. Its analog subsystem integrates four 16-/12-bit ADCs with hardware post-processing (windowed comparators, DAC references, error-from-setpoint calculation) and eight SDFM input channels for isolated shunt current sensing.

System-level timing relies on two internal zero-pin 10MHz oscillators, on-chip crystal oscillator support, and missing-clock detection. Peripheral connectivity includes two ISO 11898-1 CAN modules, three SPI ports, four SCI/UART interfaces, two I²C, USB 2.0 (MAC+PHY), uPP, and dual EMIFs supporting ASRAM/SDRAM - all mapped to 169 GPIO pins with input filtering and multiplexing.

FAQ

What is the maximum ADC sampling rate achievable with TMS320F28377SPTPS in 16-bit mode?

The TMS320F28377SPTPS supports up to 1.1MSPS per ADC in 16-bit mode, with four independent ADCs enabling a total system throughput of 4.4MSPS when synchronized. Each ADC includes a dedicated sample-and-hold circuit and hardware post-processing, allowing concurrent high-resolution acquisition across multiple power phases without CPU intervention. This performance is validated under –40°C to 125°C junction conditions.

Does TMS320F28377SPTPS support hardware-based functional safety features?

Yes, TMS320F28377SPTPS includes hardware integrity features certified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD, including ECC-protected memory, windowed watchdog timers, missing-clock detection, and hardware self-test (HWBIST). These features are implemented in silicon and documented in TI's safety manual SPRUIR7 - enabling systematic development of safety-critical motor control systems.

How many high-resolution PWM channels does TMS320F28377SPTPS provide?

TMS320F28377SPTPS provides 16 high-resolution PWM (HRPWM) channels, distributed across eight ePWM modules (A and B channels each). Each HRPWM output achieves sub-nanosecond resolution and supports independent dead-band generation, trip-zone inputs, and phase-shift control - essential for precise SiC/GaN gate driving and multi-level inverter topologies.

Is TMS320F28377SPTPS pin-compatible with other F2837xS devices in the same package?

Yes, TMS320F28377SPTPS is pin-compatible with all other F2837xS variants offered in the 176-pin HLQFP (PTP) package, including TMS320F28379SPTPS and TMS320F28377S-Q1PTP. Pin assignments, power domains, and peripheral mappings are identical; differences are limited to internal feature enablement (e.g., EMIF count, ADC instances) and qualification grade - enabling drop-in replacement in non-automotive designs.

What communication interfaces are supported by TMS320F28377SPTPS for industrial networking?

TMS320F28377SPTPS supports two ISO 11898-1/CAN 2.0B-compliant modules, four SCI/UART interfaces (with 16-level FIFOs), two I²C ports, three SPI ports, and a USB 2.0 MAC+PHY. These interfaces enable robust industrial networking - CAN for distributed motor control, UART for debugging and HMI, I²C for sensor buses, and USB for firmware updates and host diagnostics - all accessible via the 169 GPIO pins.
