Product details
Overview
F28388SZWTS from Texas Instruments is a dual-CPU real-time microcontroller featuring two 200-MHz TMS320C28x DSP cores, IEEE 754 double-precision FPU, and an independent 125-MHz Arm Cortex-M4 Connectivity Manager (CM). It integrates 1 MB flash (512 KB per C28x CPU + 512 KB CM), 216 KB RAM (44 KB local per C28x + 128 KB global + 96 KB CM), and supports industrial motor control, solar inverters, and EtherCAT slave applications.
For engineers reviewing the F28388SZWTS datasheet, F28388SZWTS pinout, F28388SZWTS application, or F28388SZWTS equivalent, key selection criteria include dual-core deterministic control latency, integrated CAN FD + EtherCAT Slave Controller, 32-channel high-resolution PWM, functional safety certification (ASIL B / SIL 2), and nFBGA-337 packaging for thermal performance in high-power-density systems.
Technical Context
The F28388SZWTS implements a heterogeneous dual-domain architecture: two synchronized C28x CPUs execute real-time control loops with TMU, VCRC, and CLA acceleration, while the isolated Cortex-M4 CM handles protocol stacks (Ethernet 1588, USB 2.0, MCAN), security (AES), and diagnostics. Memory coherency is managed via IPC and MSGRAM blocks.
Its analog subsystem includes four 16-bit/12-bit ADCs (1.1 MSPS @ 16-bit, 3.5 MSPS @ 12-bit), eight windowed comparators with DAC references, and three buffered 12-bit DACs - all tightly coupled to 32 ePWM channels with high-resolution A/B edges and dead-band support for SiC/GaN gate drive timing.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28388D | Same dual-C28x + CM architecture, identical pinout (ZWT), but rated for commercial temperature range (0°C to 85°C) vs. F28388SZWTS (–40°C to 125°C) | Targeted at non-automotive industrial equipment where extended junction temperature operation is not required | Select when ambient operating conditions remain within commercial limits and cost optimization is prioritized |
| TMS320F28386S | Single-C28x core (vs. dual), 512 KB C28x flash, 172 KB RAM, no CLA, same CM subsystem and ZWT package | Suitable for lower-complexity motor control or digital power applications where one control core suffices | Choose when deterministic dual-loop execution is unnecessary and BOM cost reduction is critical |

FAQ
What is the operating temperature range of the F28388SZWTS?
The F28388SZWTS is qualified for –40°C to 125°C junction temperature operation, making it suitable for harsh industrial environments such as enclosed motor drives, outdoor solar inverters, and under-hood EV power electronics. This extended range exceeds the commercial-grade F28388D and aligns with AEC-Q100 Class 0 requirements for reliability in demanding thermal conditions. The F28388SZWTS maintains full specification compliance across this range, including flash ECC, RAM parity, and analog subsystem accuracy.
Does the F28388SZWTS support EtherCAT Slave functionality?
Yes, the F28388SZWTS includes a fully integrated EtherCAT Slave Controller (ESC) with dual-port PHY interface, enabling direct connection to EtherCAT networks without external ASICs. The ESC operates within the Connectivity Manager (CM) subsystem and supports sub-microsecond jitter synchronization via Ethernet 1588 timestamping. This capability is confirmed in the device's functional block diagram and peripheral list, and is supported by TI's EtherCAT firmware stack in C2000Ware. The F28388SZWTS ESC is functionally identical to that in the F28388D and F28386S families.
How many high-resolution PWM channels does the F28388SZWTS provide?
The F28388SZWTS provides 16 high-resolution PWM channels - eight modules with high-resolution capability on both A and B outputs. Each channel supports programmable dead-band, trip-zone protection, and event-triggered ADC start. This configuration enables precise gate-drive timing for multilevel topologies (e.g., three-level NPC, T-type inverters) and SiC/GaN devices requiring nanosecond-level resolution. The high-resolution feature is implemented in hardware and does not consume CPU cycles, preserving deterministic loop execution on the C28x cores.
Is the F28388SZWTS certified for functional safety standards?
Yes, the F28388SZWTS is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. These certifications cover hardware capability, failure modes, diagnostic coverage, and systematic development processes. Documentation including FMEDA reports, safety manuals, and diagnostic software libraries is available through TI's functional safety portal. The F28388SZWTS shares the same safety qualification as other F2838x-S variants, and its dual-core architecture with IPC and memory protection supports safe partitioning of control and monitoring tasks.
What package type is used for the F28388SZWTS?
The F28388SZWTS uses the 337-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZWT suffix, measuring 16 mm × 16 mm. This package features optimized thermal dissipation for high-power-density applications and supports fine-pitch PCB routing. It is pin-compatible with other F2838x devices in the ZWT variant, including F28388D, F28386S, and F28384S. The nFBGA construction enables reliable operation at 125°C junction temperature and meets JEDEC J-STD-020 moisture sensitivity level 3 requirements.
