TMS320F28376SQ-Q1 Présentation
A real-time microcontroller (MCU) is a single-chip processor optimized for deterministic closed-loop control rather than general-purpose throughput. Within the power-management IC hierarchy, the C2000 Delfino family sits at the high end of TI's real-time MCU portfolio, bridging entry-level C2000 devices (TMS320F2800x) and multicore Delfino parts (TMS320F28379D). The F2837xS family, documented in TI datasheet ZHCSE97K, targets advanced closed-loop control such as industrial motor drives, solar inverters, digital power, electric vehicles, and sensing and signal processing.
Key features include the 200 MHz C28x core with a floating-point unit (FPU) and Trigonometric Math Unit (TMU) for fast sin/cos/park-transform math, a Control Law Accelerator (CLA) that offloads control loops from the main CPU, 16-bit ADCs for high-precision current and voltage sensing, and an External Memory Interface (EMIF) for parallel memory expansion. Rich on-chip peripherals include ePWM, eCAP, eQEP, CAN, SPI, and serial communication modules, enabling complete digital-power and traction-control systems on a single chip.
Architecturally, the device executes from fast on-chip SRAM and flash with pipelined protection, and TI's DigitalPower SDK and C2000Ware software accelerate development of FOC motor control, LLC/PFC power stages, and onboard-charger firmware. According to the TI TMS320F28377S-Q1 product page, the -Q1 automotive grade variant supports AEC-Q100 workflows for EV, transportation, and functional-safety-oriented designs.
Typical applications include traction-inverter and auxiliary motor control in electric vehicles, solar string and central inverter DSP-stage control, and high-density digital power supplies where 200 MHz real-time throughput and 16-bit ADC precision directly improve loop bandwidth and efficiency.
Design tip: budget flash and CLA tasks carefully - the single-CPU F2837xS architecture relies on CLA offload to achieve dual-loop control rates; verify peripheral pinmux options against the datasheet before finalizing PCB routing.

Applications typiques
TMS320F28376SQ-Q1 convient pour 6 applications: Electric Vehicle Traction and Auxiliary Motor Control, Solar Inverters and Digital Power, Industrial Servo and Robotics Drives, Onboard Chargers and DC-DC Converters, Sensing and Signal Processing Nodes, Transportation and Rail Power Systems.
Electric Vehicle Traction and Auxiliary Motor Control
The TMS320F28376SQ-Q1 fits EV motor control because its 200 MHz C28x core with FPU and TMU executes field-oriented-control trigonometry in hardware, while the CLA runs high-rate current loops independently. In an inverter stack, it samples phase currents with 16-bit ADCs and drives gate drivers through high-resolution ePWM modules. The Q1 automotive grade supports AEC-Q100 workflows required in traction and auxiliary (pump/fan/compressor) drives.
Recommandé
Solar Inverters and Digital Power
Solar string and central inverters demand deterministic control of MPPT, DC-link balancing, and grid-current loops. The F28376SQ-Q1's 400 MIPS throughput, CLA offload, and EMIF for expansion memory make it well suited to run cascaded control loops at 10-100 kHz switching frequencies. TI's DigitalPower SDK ships PFC, LLC, and inverter reference firmware for this C2000 family, reducing development risk.
Recommandé
Industrial Servo and Robotics Drives
Servo drives require fast current loops plus position feedback processing. The TMS320F28376SQ-Q1 processes eQEP encoder inputs and executes cascaded position/velocity/current loops on one chip; the TMU accelerates coordinate transforms. Its 16-bit ADC resolution improves torque linearity at low speeds, and CAN interfaces connect to industrial fieldbus gateways, making it a strong single-chip real-time controller for factory automation.
Recommandé
Onboard Chargers and DC-DC Converters
OBC and high-voltage DC-DC converters need PFC plus isolated DCX control with interleaved phases. The F28376SQ-Q1's high-resolution ePWM and 200 MHz core run phase-shifted full-bridge and totem-pole PFC firmware from TI's DigitalPower SDK. The Q1 automotive grade and CLA-based fast loops meet EV power-conversion requirements, while 16-bit ADCs capture precise voltage/current feedback for accurate power regulation.
Recommandé
Sensing and Signal Processing Nodes
The F2837xS family is explicitly positioned by TI for sensing and signal processing. With 16-bit ADCs and 400 MIPS DSP-class throughput, the TMS320F28376SQ-Q1 can perform real-time FFT, filtering, and condition monitoring on vibration, current, or acoustic signals, then report results over CAN or SPI. EMIF allows external memory expansion for buffering long data records in predictive-maintenance systems.
Recommandé
Transportation and Rail Power Systems
Beyond road vehicles, the AEC-Q100-qualified F28376SQ-Q1 serves rail auxiliary converters, e-bus power electronics, and off-highway electrification. Its real-time control determinism handles converter supervision and protection trips in microseconds, while the EMIF and rich communication set integrate with vehicle control units. Long-lifecycle automotive qualification supports the multi-year service requirements typical of transportation programs.

Notes de conception
The F2837xS requires dual-rail sequencing: 1.2 V core (VDD) and 3.3 V I/O (VDDIO). Use a power supervisor or TI's recommended PMIC/sequencing scheme from the C2000 power design reference so the core rail is stable before or with I/O. Follow the datasheet ZHCSE97K decoupling layout: bulk plus 0.1 uF ceramics at every VDD/VDDIO pin pair, and place VREFHI decoupling and filtering close to the ADC reference pin for 16-bit accuracy.
For the 176-HTQFP, route high-speed ePWM outputs to gate drivers with matched lengths and keep them away from ADC traces. Use a solid ground plane under the ADC section and star-route VREFHI with RC filtering (e.g., ferrite plus 1 uF + 0.1 uF). Follow TI C2000 hardware design guidelines app note for JTAG (14-pin cTI header) placement within 6 inches of the MCU.
The F2837xS is single-CPU (unlike dual-core F28379D) - firmware ported from dual-core parts must consolidate tasks onto the C28x plus CLA. Also verify flash capacity: 512 KB on F28376S vs 1024 KB on F28377S; code that barely fits on dual-bank parts may not link. Use the PinMux utility early because many GPIO functions are multiplexed and only specific ePWM/ADC pins reach package balls.
EMIF operation above 50 MHz needs careful trace impedance control (50 ohm) and series termination on address/data lines; consult the EMIF section of the TMS320F2837xS TRM. For CAN, use SN65HVD255QDRQ1-class transceivers with proper split termination (60.4 ohm x2 + split cap) and keep the MCU crystal loop traces short with ground guard.
