Product details
Overview
F28388SPTPSR from Texas Instruments is a dual-core real-time microcontroller featuring two 200-MHz C28x DSP CPUs, a 125-MHz Arm Cortex-M4 Connectivity Manager, 1 MB total flash (512 KB per CPU + 512 KB CM), 216 KB RAM (44 KB ×2 local + 128 KB global + 96 KB CM), and integrated EtherCAT Slave Controller, CAN FD, USB 2.0, and 10/100 Ethernet - deployed in industrial motor drives and solar inverters requiring deterministic control and protocol offload.
For engineers reviewing the F28388SPTPSR datasheet, F28388SPTPSR pinout, F28388SPTPSR application, or F28388SPTPSR equivalent, key selection criteria include dual-CPU real-time determinism, CM-based protocol handling (EtherCAT/CAN FD/USB/Ethernet), CLB programmability for custom logic, functional safety certification (ASIL B/SIL 2), and support for GaN/SiC power stages via high-resolution PWM and fast ADCs.
Technical Context
The F28388SPTPSR implements a tightly coupled heterogeneous architecture: two independent C28x CPUs execute real-time control loops with IEEE 754 double-precision FPU, TMU, and CLA acceleration, while the dedicated Arm Cortex-M4 CM handles connectivity, security (AES), and protocol stacks - enabling full separation of control and communication tasks without resource contention.
Its analog subsystem integrates four 16-bit/12-bit ADCs (1.1 MSPS/3.5 MSPS), eight windowed comparators with DAC references, three buffered DAC outputs, and SDFM filters; control peripherals deliver 32 ePWM channels (16 high-resolution), seven eCAP modules (two with HRCAP), and three eQEP modules - all synchronized across CPU domains via IPC and MSGRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28388DPTPSR | Same package and pinout; automotive-grade (–40°C to 125°C ambient, AEC-Q100 qualified); higher flash retention spec | Required for automotive OEM production; supports extended temperature validation and PPAP documentation | Select when automotive qualification, longer data retention, or AEC-Q100 compliance is mandatory |
| TMS320F28386SPTPSR | Single-C28x core (no CPU2), 512 KB C28x flash, 172 KB RAM, no CLB, no EtherCAT ESC, same CM subsystem | Suitable for cost-sensitive servo drives or smaller inverters where dual-core determinism and EtherCAT are not required | Select when reduced code size, lower BOM cost, and simplified software architecture outweigh dual-core and EtherCAT needs |
Compared with F28388SPTPSR, the F28388DPTPSR adds automotive qualification and enhanced reliability specs but shares identical real-time performance and feature set; the F28386SPTPSR removes one CPU, CLB, and EtherCAT - trading capability for cost and footprint in less demanding applications.

FAQ
What is the operating temperature range for F28388SPTPSR?
The F28388SPTPSR is rated for –40°C to 125°C junction temperature. This S-grade specification supports deployment in harsh industrial environments such as enclosed motor drives and outdoor solar inverters where ambient heat buildup occurs. The device uses internal thermal sensors and DCC circuitry to monitor die temperature and trigger safe shutdown if limits are exceeded - ensuring reliable operation within its specified thermal envelope. F28388SPTPSR does not require external temperature compensation for ADC or PWM timing calibration under this range.
Does F28388SPTPSR support pin-compatible migration from earlier C2000 devices?
No, F28388SPTPSR is not pin-compatible with prior-generation C2000 MCUs such as F2837x or F28004x families due to its 176-pin HLQFP and 337-ball nFBGA packages, expanded GPIO count (169), and new peripheral signal assignments (e.g., ESC, FSI, MCAN). Migration requires PCB redesign and firmware adaptation to leverage dual-CPU, CLB, and CM capabilities. F28388SPTPSR pinout is shared only with other F2838x variants (e.g., F28388DPTPSR) in the same package option.
How is functional safety implemented in F28388SPTPSR?
F28388SPTPSR implements functional safety through hardware features including dual-clock comparator (DCC), windowed watchdog timers, hardware BIST (HWBIST), ERAD debug trace, and dual-zone security - all validated under ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD. These features enable systematic fault detection and recovery in safety-critical motor control and power conversion applications. F28388SPTPSR does not require external safety monitors to meet ASIL B requirements when used per TI's safety manual and diagnostic software library.
Can F28388SPTPSR run EtherCAT and CAN FD simultaneously?
Yes, F28388SPTPSR supports concurrent EtherCAT and CAN FD operation: the EtherCAT Slave Controller (ESC) operates on dedicated hardware channels (ESC_TX0/ESC_RX0), while MCAN0 and MCAN1 are fully independent CAN FD modules with separate message RAM and configuration registers. Both protocols can be active during real-time control - for example, EtherCAT for motion synchronization and CAN FD for diagnostics or vehicle bus communication - without CPU intervention or timing conflict, as managed by the CM and C28x DMA engines respectively.
What development tools are supported for F28388SPTPSR?
F28388SPTPSR is supported by TI's C2000Ware SDK, Code Generation Tools v22.x+, and CCS v12.x IDE. Hardware evaluation is enabled by the TMDSCNCD28388D controlCARD and LAUNCHXL-F28388D LaunchPad. Debugging uses JTAG (14-/20-pin headers) with real-time analysis via ERAD and CLA trace. F28388SPTPSR also integrates with TI's MotorControl SDK, DigitalPower SDK, and EtherCAT slave stack - all available free of charge with full source code and reference examples.
