Product details
Overview
F28386SPTPS from Texas Instruments is a dual-CPU real-time microcontroller with integrated Arm Cortex-M4 Connectivity Manager, delivering 200 MHz C28x DSP performance per core and 125 MHz CM operation. It features 512KB flash per C28x CPU (ECC-protected), 128KB global shared RAM (parity-protected), IEEE 754 double-precision FPU, and hardware-accelerated EtherCAT Slave Controller - deployed in servo drive control modules requiring deterministic low-latency motor control and industrial Ethernet connectivity.
For engineers reviewing the F28386SPTPS datasheet, F28386SPTPS pinout, F28386SPTPS application, or F28386SPTPS equivalent, key selection criteria include dual-core C28x + Arm M4 partitioning, 176-pin HLQFP package with 97 GPIOs, CAN FD and MCAN support, 16-bit/1.1 MSPS ADC capability, and functional safety certification up to ASIL B/SIL 2.
Technical Context
The F28386SPTPS implements a tightly coupled heterogeneous architecture: two independent TMS320C28x CPUs (200 MHz) each with dedicated 512KB ECC flash and 44KB local RAM, plus a separate Arm Cortex-M4 subsystem (125 MHz) with 512KB ECC flash and 96KB RAM. The CM handles protocol offload (Ethernet 1588, USB 2.0, CAN FD), while C28x cores execute real-time control loops using CLA accelerators and high-resolution PWMs.
Its analog subsystem integrates four 16-bit/1.1 MSPS ADCs with hardware post-processing, eight windowed comparators, three 12-bit DACs, and SDFM filters - enabling closed-loop current/voltage sensing in GaN/SiC-based inverters. The device supports dual-zone security, ERAD debugging, and HWBIST for functional safety workflows compliant with ISO 26262 ASIL B and IEC 61508 SIL 2.

FAQ
What is the maximum operating junction temperature for F28386SPTPS?
The F28386SPTPS is rated for a maximum junction temperature of 125°C, consistent with its S-grade industrial temperature specification (–40°C to 125°C). This rating applies under specified thermal conditions using the 176-pin HLQFP package with proper PCB copper pour and thermal vias beneath the PowerPAD. Derating curves in the datasheet define allowable power dissipation versus ambient temperature and airflow.
Does F28386SPTPS support pin-compatible migration from earlier C2000 devices like F2837x?
No, F28386SPTPS is not pin-compatible with F2837x-series devices due to architectural expansion - it adds Connectivity Manager peripherals, additional GPIOs, and revised power domain routing. Migration requires PCB redesign and firmware adaptation to leverage dual-C28x + Arm M4 partitioning, EtherCAT, and CAN FD capabilities unique to the F2838x family.
How is functional safety implemented in F28386SPTPS for ASIL B compliance?
F28386SPTPS achieves ASIL B compliance through hardware safety mechanisms including dual-clock comparator (DCC), windowed watchdog timer, hardware BIST (HWBIST), memory ECC/parity protection, and lockstep-capable peripherals. Texas Instruments provides a certified safety manual, FMEDA report, and diagnostic software library - all validated by TÜV SÜD for use in safety-related motor control systems.
Can the CLB in F28386SPTPS replace an external FPGA in position manager applications?
Yes, the eight Configurable Logic Block (CLB) tiles in F28386SPTPS can implement position manager logic - such as commutation state machines, Hall sensor interpolation, or resolver-to-digital conversion - without external components. Each CLB supports LUTs, flip-flops, and block RAM, and integrates directly with eQEP and ePWM peripherals via dedicated XBAR routing.
What boot modes are supported by F28386SPTPS?
F28386SPTPS supports multiple boot modes including flash, SCI (UART), SPI, I²C, CAN, USB, and EMIF. Boot configuration is controlled by GPIO pins at reset, and the device includes a ROM bootloader with cryptographic signature verification for secure firmware updates - essential for industrial field deployments requiring authenticated code loading.
