It integrates four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and 169 GPIOs. It targets high-precision motor control in EV traction inverters and solar power converters.

For engineers reviewing the TMS320F28375SZWTS datasheet, TMS320F28375SZWTS pinout, TMS320F28375SZWTS application, or TMS320F28375SZWTS equivalent, key selection criteria include its single-CPU/CLA subsystem architecture, ZWT nFBGA-337 package, –40°C to 125°C junction temperature rating, functional safety compliance (ISO 26262 ASIL B, IEC 61508 SIL 2), and integrated analog/control peripherals for closed-loop timing-critical systems.

Technical Context

The TMS320F28375SZWTS implements a single-C28x CPU + CLA subsystem (200MHz each), distinguishing it from dual-subsystem F2837xD variants. Its analog subsystem includes four independent ADCs supporting simultaneous 16-bit (1.1MSPS) and 12-bit (3.5MSPS) modes with hardware post-processing, SDFM, and eight windowed comparators with 12-bit DAC references.

Control peripherals feature 24 ePWM channels with dead-band support on both standard and high-resolution outputs, six eCAP modules, three eQEP modules, and configurable logic blocks (CLB) augmenting peripheral capability for position manager solutions. Communications include two ISO 11898-1 CAN modules, four SCI/UARTs, three SPIs, two I2Cs, USB 2.0 (MAC+PHY), and uPP interface.

FAQ

What is the maximum ADC sampling rate achievable with TMS320F28375SZWTS in 12-bit mode?

The TMS320F28375SZWTS supports up to 3.5MSPS per ADC in 12-bit mode, with four independent ADCs enabling a total system throughput of 14MSPS. This allows simultaneous sampling of multiple current/voltage channels in multi-phase motor drives and inverters without external multiplexing, preserving timing coherence across critical feedback paths.

Does TMS320F28375SZWTS support functional safety certification for automotive use?

Yes, the TMS320F28375SZWTS is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. Its hardware integrity, diagnostic coverage (including HWBIST), and safety documentation support system-level development for automotive motor control and charging applications meeting stringent safety requirements.

How many high-resolution PWM channels does TMS320F28375SZWTS provide?

The TMS320F28375SZWTS provides 16 high-resolution PWM (HRPWM) channels, distributed across eight ePWM modules where both A and B outputs support high-resolution enhancement. This enables precise gate drive timing for SiC and GaN power devices with sub-nanosecond resolution and programmable dead-band insertion on all channels.

What package type and ball count does TMS320F28375SZWTS use?

TMS320F28375SZWTS uses the 337-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZWT suffix, measuring 16mm × 16mm. This high-density package supports 169 GPIOs and full peripheral access while maintaining thermal performance suitable for high-power density applications like onboard chargers and servo drives.

Can TMS320F28375SZWTS execute control code independently on its CLA coprocessor?

Yes, the TMS320F28375SZWTS features a fully autonomous Control Law Accelerator (CLA) running at 200MHz, capable of executing floating-point control algorithms triggered by peripheral events (e.g., ADC end-of-conversion or PWM timer overflow) without CPU intervention - effectively doubling real-time processing capacity for time-critical loops.
