Product details
Overview
TMS320F28386SPTPQR 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 (CM), IEEE 754 double-precision FPU, 512KB flash per CPU, and 128KB global shared RAM - deployed in industrial motor drives, solar inverters, and servo control systems requiring deterministic low-latency execution.
For engineers reviewing the TMS320F28386SPTPQR datasheet, TMS320F28386SPTPQR pinout, TMS320F28386SPTPQR application, or TMS320F28386SPTPQR equivalent, key selection criteria include dual-CPU real-time determinism, CM-based protocol offload (CAN FD, EtherCAT, USB 2.0, 10/100 Ethernet), integrated analog subsystem (four 16-bit ADCs, 32 ePWM channels), functional safety certification (ISO 26262 ASIL B, IEC 61508 SIL 2), and HLQFP-176 thermal performance.
Technical Context
The TMS320F28386SPTPQR implements a heterogeneous dual-domain architecture: the C28x subsystem handles time-critical control loops with hardware-accelerated math (TMU, VCRC, CLA), while the independent Cortex-M4 CM executes connectivity, security (AES), and protocol stacks (EtherCAT Slave Controller, MCAN, USB MAC+PHY) without CPU1/CPU2 interference. Inter-processor communication uses IPC with MSGRAM and hardware semaphore support.
Its analog subsystem integrates four synchronized 16-bit/12-bit ADCs (1.1 MSPS @16-bit, 3.5 MSPS @12-bit), eight windowed comparators with DAC references, three buffered 12-bit DACs, and eight SDFM input channels - enabling closed-loop sensing for multi-axis motor control and power converter monitoring.

FAQ
What is the core architecture of the TMS320F28386SPTPQR?
The TMS320F28386SPTPQR features a heterogeneous dual-domain architecture: one 200-MHz TMS320C28x DSP core for real-time control and a separate 125-MHz Arm Cortex-M4 Connectivity Manager (CM) for protocol handling and security. It does not include a second C28x CPU - unlike the F28388D or F28386D variants. This configuration balances deterministic control performance with robust connectivity offload in the TMS320F28386SPTPQR.
Does the TMS320F28386SPTPQR support EtherCAT communication?
Yes, the TMS320F28386SPTPQR integrates a dedicated EtherCAT Slave Controller (ESC) within its Connectivity Manager subsystem. This hardware block handles frame processing, mailbox management, and distributed clock synchronization independently of the C28x CPU, enabling sub-microsecond jitter in industrial automation networks - a confirmed capability documented in the TMS320F28386SPTPQR datasheet Section 1 and Functional Block Diagram.
What package and thermal specifications apply to the TMS320F28386SPTPQR?
The TMS320F28386SPTPQR uses the 176-pin HLQFP (PTP) package with PowerPAD™ thermal enhancement, measuring 24 mm × 24 mm. It is rated for –40°C to 125°C junction temperature operation and includes an exposed thermal pad for PCB-level heat dissipation. Thermal resistance (θJA) is 22.5°C/W under JEDEC JESD51-7 conditions - verified in the official TI packaging documentation for the PTP variant.
Is the TMS320F28386SPTPQR certified for functional safety applications?
Yes, the TMS320F28386SPTPQR is ISO 26262 ASIL B certified by TÜV SÜD and IEC 61508 SIL 2 certified, with hardware-level safety mechanisms including ECC-protected memory, parity-protected RAM, windowed watchdog timers, and hardware BIST. These certifications apply specifically to the TMS320F28386SPTPQR device variant and are detailed in TI's functional safety documentation package for the F2838x family.
How does the analog subsystem of the TMS320F28386SPTPQR support motor control?
The TMS320F28386SPTPQR integrates four synchronized 16-bit/12-bit ADCs (1.1 MSPS @16-bit), eight windowed comparators with DAC references, three 12-bit buffered DAC outputs, and eight SDFM input channels. This enables simultaneous current/voltage sampling, overcurrent protection with <100 ns response, and isolated sigma-delta sensor interfacing - all directly supporting field-oriented control and fault management in the TMS320F28386SPTPQR.
