Product details
Overview
TMS320F2806ZGMSR from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and 12-bit 3.46-MSPS ADC, designed for closed-loop motor control and digital power conversion in industrial inverters and EV charging modules.
For engineers reviewing the TMS320F2806ZGMSR datasheet, TMS320F2806ZGMSR pinout, TMS320F2806ZGMSR application, or TMS320F2806ZGMSR equivalent, key selection criteria include ePWM resolution (HRPWM-capable), on-chip analog integration (3 comparators + DACs), security features (128-bit key), USB 2.0 support, and thermal performance in HTQFP-80 PowerPAD™ packaging.
Technical Context
The TMS320F2806ZGMSR implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory mapping, paired with a dedicated 32-bit floating-point CLA that offloads real-time control loops independently of the main CPU. Its VCU extends instruction set support for CRC, complex math, and Viterbi decoding.
It integrates dual-sample-and-hold ADC with 16-channel input multiplexing, ratio-metric reference support (VREFHI/VREFLO), and DMA-accessible result registers; all ePWM modules support dual-edge modulation via HRPWM, and trip-zone protection is routed directly from analog comparators to PWM outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049C | Higher 100-MHz CPU, CLB logic blocks, improved ADC SNR (72 dB), but no USB; 100-pin LQFP only | Targeted at next-gen servo drives requiring configurable logic for custom encoder interfaces or protection logic | Select when needing CLB-based hardware acceleration or higher analog precision; not drop-in due to pinout and peripheral differences |
| TMS320F28069M | Same 90-MHz C28x/FPU/CLA, identical pinout (100-pin PZP), but adds InstaSPIN-MOTION™ firmware and 128 KB flash | Pre-integrated motion control libraries reduce development time for multi-axis CNC or robotics systems | Choose for rapid prototyping with TI's motion control SDK; requires same PCB layout but different firmware stack |
Compared with TMS320F2806ZGMSR, the TMS320F280049C offers higher compute headroom and analog fidelity for advanced servo tuning, while the TMS320F28069M provides validated motion control firmware at the cost of reduced USB flexibility - both require board-level validation for thermal and signal integrity in high-frequency inverter designs.

FAQ
What is the maximum operating frequency of the TMS320F2806ZGMSR?
The TMS320F2806ZGMSR operates at a maximum CPU frequency of 90 MHz, delivering a 11.11-ns instruction cycle time. This speed is sustained across its full temperature range (–40°C to 105°C) and enables sub-microsecond interrupt latency and deterministic execution of complex control algorithms such as field-oriented control (FOC) and model-predictive control (MPC) in real-time applications. The TMS320F2806ZGMSR achieves this performance with on-chip PLL clock synthesis from internal oscillators or external crystal sources.
Does the TMS320F2806ZGMSR support USB functionality?
Yes, the TMS320F2806ZGMSR includes a full-speed USB 2.0 PHY with device and host mode support, accessible via dedicated USB0DP and USB0DM pins. It supports enumeration, bulk/isochronous transfers, and HID-class implementations without requiring external transceivers. This capability is confirmed in the device comparison table and functional block diagram of the official datasheet (SPRS698J), and is enabled by on-chip USB module firmware and DMA-accelerated data movement.
What package type is used for the TMS320F2806ZGMSR?
The TMS320F2806ZGMSR uses an 80-pin HTQFP PowerPAD™ package (PFP suffix), measuring 12.0 mm × 12.0 mm with an exposed thermal pad. This thermally enhanced package requires soldering the PowerPAD to the PCB ground plane to achieve optimal thermal performance (≤40°C/W junction-to-board). Pin assignments match the 80-pin PN/PFP footprint defined in TI's mechanical documentation, and the device shares pin compatibility with other F2806x variants in the same package family.
How many high-resolution PWM channels does the TMS320F2806ZGMSR provide?
The TMS320F2806ZGMSR provides 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules (EPWM1–EPWM8), with each module offering dual outputs (A/B). These HRPWM channels support sub-nanosecond timing resolution and dual-edge modulation, enabling precise dead-time control essential for SiC and GaN-based inverter designs. This specification is explicitly listed in the Device Comparison table (Table 5-1) and verified in the peripheral description section of the datasheet.
Is the TMS320F2806ZGMSR qualified for automotive applications?
No, the TMS320F2806ZGMSR is not AEC-Q100 qualified. It is rated for industrial temperature range (–40°C to 105°C, 'T' grade) and packaged in the PFP variant, which lacks automotive qualification. For automotive use, TI offers the pin-compatible TMS320F28069M-Q1 or TMS320F28069F-Q1 (100-pin PZP), both certified to AEC-Q100 Grade 1 (–40°C to 125°C) and featuring Q-grade screening and extended reliability testing - the TMS320F2806ZGMSR itself does not carry Q1 suffix or automotive qualification markings.
