Product details
Overview
F28388SPTPS 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 shared + 96 KB CM), and supports industrial motor control, solar inverters, and EV on-board chargers.
For engineers reviewing the F28388SPTPS datasheet, F28388SPTPS pinout, F28388SPTPS application, or F28388SPTPS equivalent, key selection criteria include dual-core deterministic control latency, integrated EtherCAT Slave Controller, CAN FD support, 32-channel high-resolution PWM, and functional safety certification up to ASIL B / SIL 2.
Technical Context
The F28388SPTPS implements a heterogeneous dual-subsystem architecture: two synchronized C28x CPUs execute real-time control loops with hardware acceleration (TMU, VCRC, CLA), while the isolated Arm Cortex-M4 CM handles protocol stack offload (Ethernet 1588, USB 2.0, MCAN) and security services (AES, dual-zone DCSM). Memory coherency is managed via IPC and MSGRAM with hardware semaphore support.
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 logic for GaN/SiC gate drive timing precision.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28388DPTP | Same package and pinout; automotive-grade (-40°C to 125°C ambient, AEC-Q100 qualified); identical core/peripheral specs. | Required for automotive OEM production where ambient temperature qualification and PPAP documentation are mandatory. | Select F28388DPTP when AEC-Q100 compliance and automotive lifecycle support are required; F28388SPTPS is optimized for industrial temperature range and cost-sensitive industrial designs. |
| TMS320F28386SPTP | Single C28x CPU (200 MHz), 512 KB flash, 172 KB RAM, no CLA, no EtherCAT, reduced GPIO count (97 vs. 169), same CM subsystem. | Suitable for cost-constrained single-axis servo drives or smaller inverters where dual-core redundancy and advanced networking are unnecessary. | Choose F28386SPTP when dual-CPU determinism and EtherCAT are not needed - reduces software complexity and licensing costs while retaining CM-based connectivity. |
Compared with F28388DPTP, F28388SPTPS trades automotive qualification for lower industrial-tier pricing and identical real-time performance; versus F28386SPTP, it adds critical dual-core control headroom, EtherCAT, and full GPIO count - essential for multi-axis motion control and grid-edge power electronics.

FAQ
What is the operating temperature range for the F28388SPTPS?
The F28388SPTPS is rated for –40°C to 125°C junction temperature, making it suitable for demanding industrial environments such as enclosed motor drives and outdoor solar inverters. This S-temperature grade differs from the Q-grade (ambient-rated) F28388DPTP used in automotive under-hood applications. Thermal design must maintain junction temperature within spec using the HLQFP package's PowerPAD thermal path.
Does the F28388SPTPS support EtherCAT Slave functionality?
Yes, the F28388SPTPS includes a dedicated EtherCAT Slave Controller (ESC) integrated into its Connectivity Manager subsystem. This hardware block handles frame processing, mailbox communication, and distributed clock synchronization independently of both C28x CPUs, enabling deterministic <1 µs jitter in motion control networks without CPU overhead.
How many high-resolution PWM channels does the F28388SPTPS provide?
The F28388SPTPS provides 32 ePWM channels, with high-resolution capability on both A and B edges of all 8 ePWM modules (16 total high-res channels). Each channel supports 150-ps resolution, programmable dead-band, trip-zone inputs, and event-triggered ADC start - essential for precise SiC/GaN gate timing in multilevel topologies.
Is the F28388SPTPS functionally safe certified?
Yes, the F28388SPTPS is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. Certification covers hardware fault tolerance, diagnostic coverage, and systematic capability - supported by on-chip features including windowed watchdog, dual-clock comparator, ERAD trace, and hardware BIST.
What package options are available for the F28388SPTPS?
The F28388SPTPS is offered exclusively in the 176-pin PowerPAD™ Thermally Enhanced Low-profile Quad Flatpack (HLQFP) package (PTP suffix), measuring 24 mm × 24 mm. Unlike the ZWT nFBGA variant, the PTP package provides superior thermal dissipation for high-power density industrial applications and simplified PCB assembly with standard reflow profiles.
