Product details
Overview
TMS320F28054FPNQ from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated CLA accelerator, 14 ePWM channels, 12-bit 3.75-MSPS ADC, and dual-zone security-designed for automotive-grade motor control in air conditioner outdoor units and BLDC drives.
For engineers reviewing the TMS320F28054FPNQ datasheet, TMS320F28054FPNQ pinout, TMS320F28054FPNQ application, or TMS320F28054FPNQ equivalent, key selection criteria include AEC Q100 qualification (–40°C to 125°C), on-chip PGAs and comparators for analog loop closure, and eCAN/SCI/UART/SPI/I²C interface support for system-level communication and diagnostics.
Technical Context
The TMS320F28054FPNQ implements a Harvard-architecture 32-bit C28x CPU with atomic operations and fast interrupt response, paired with a standalone 32-bit floating-point CLA for parallel control-law execution-enabling deterministic sub-microsecond loop timing in closed-loop motor control.
Its analog front end includes seven comparators (three with internal DAC references), four programmable-gain amplifiers (gain ≈ 3/6/11), one buffered reference DAC, and dual-sample-and-hold ADC architecture supporting simultaneous sampling across 16 channels at 267 ns conversion time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C28x 32-bit fixed-point core @ 60 MHz (16.67-ns cycle time), Harvard bus, unified memory model |
| CLA | Independent 32-bit floating-point math accelerator-executes control loops concurrently with CPU |
| ADC | 12-bit, 3.75 MSPS, 16-channel with dual sample-and-hold; 267 ns conversion time, ratio-metric VREFHI/VREFLO support |
| ePWM | 14 channels with high-resolution dead-time control, trip-zone inputs, and synchronization I/O for multi-phase inverter gate driving |
| Analog Peripherals | 7 comparators (3 with integrated DACs), 4 PGAs (gain ≈ 3/6/11), 1 buffered reference DAC, 4 digital filters |

Pinout & Package
80-pin Low-Profile Quad Flatpack (LQFP), 12.0 mm × 12.0 mm body size, 0.5-mm pitch. Pin 1 marked by dot; top-side marking includes TI logo, device code, and date code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA / VSSA | Analog power/ground | Separate 3.3-V analog supply domain; requires local 2.2-μF decoupling for ADC/PGA stability |
| ADCINA0–ADCINA7, ADCINB0–ADCINB7 | Analog input channels | Two independent 8-channel ADC groups (A/B); op-amp-labeled pins support direct PGA/comparator routing |
| VREFHI / VREFLO / VREFOUT | ADC reference system | VREFHI/VREFLO set full-scale range (0–3.3 V); VREFOUT provides buffered 1.2-V reference for external circuitry |
| GPIO0–GPIO42 | Multiplexed I/O | 42 GPIOs with per-pin pullup enable/disable; default reset state is GPIO function (not peripheral) |

| Real-time debug & trace | Hardware-supported analysis and breakpoints; real-time watchpoint triggering without halting CPU or CLA execution |
| Code compatibility | Binary-compatible with prior C28x-based MCUs-enables reuse of legacy motor control firmware and libraries |
Applications
| Air Conditioner Outdoor Unit | Inverter Motor Drive |
|---|---|
Use Scenario: Variable-speed compressor and fan control in residential/commercial HVAC systems requiring precise torque regulation and thermal management. IC Role / Device Role / Timing Role: Real-time MCU executing field-oriented control (FOC) and sensorless estimation algorithms; manages ePWM timing, ADC sampling, and thermal shutdown logic. Use Value: Integrated PGAs and comparators reduce external signal conditioning; 3.75-MSPS ADC enables <1-μs current sampling latency for high-bandwidth current loops. | Use Scenario: Closed-loop speed/torque control of PMSM or induction motors in industrial drives, UPS, or solar inverters. IC Role / Device Role / Timing Role: Primary controller coordinating 14-channel ePWM generation, dual ADC sampling, and eCAN-based system monitoring and diagnostics. Use Value: CLA offloads PID and FOC calculations from main CPU-freeing C28x core for communication, safety checks, and supervisory tasks. |
| AC-input BLDC Drive | Door Operator Control |
Use Scenario: High-efficiency, low-noise BLDC motor control in appliances and building automation using AC line input and PFC stage coordination. IC Role / Device Role / Timing Role: Dual-role controller managing PFC gate drive (via GPIO34/CTRIPPFCOUT), inverter ePWM outputs, and analog sensing of DC-link voltage/current. Use Value: On-chip comparators with DAC references provide fast overcurrent protection (<100 ns response); ePWM sync I/O coordinates PFC/inverter timing without external logic. | Use Scenario: Safety-critical door actuation in elevators, garage doors, or access gates requiring position sensing, obstacle detection, and emergency stop compliance. IC Role / Device Role / Timing Role: Safety-aware MCU running dual-core lockstep not applicable, but uses dual-zone security, watchdog supervision, and eQEP-based position tracking. Use Value: AEC Q100 qualification ensures reliability in continuous-duty cycles; GPIO-trip zone inputs enable hardware-level emergency stop assertion independent of software state. |
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 |
|---|---|---|---|
| TMS320F28055PN | Includes CLA accelerator and 64 KB Flash (vs. 64 KB in TMS320F28054FPNQ); identical pinout and peripheral set | Same automotive temperature grade and AEC Q100 qualification; supports larger control algorithms due to CLA | Select when CLA-based parallel processing is required for complex observer or adaptive control loops |
| TMS320F28052QPQ | Lower Flash (16 KB) and SARAM (6 KB); no CLA; same 80-pin LQFP package and AEC Q100 rating | Targeted at cost-sensitive, lower-complexity motor control where CLA and large code footprint are unnecessary | Select for simpler scalar or V/f drives where deterministic latency is less critical than BOM cost |
Compared with TMS320F28055PN, TMS320F28054FPNQ omits the CLA but retains full analog integration and AEC Q100 compliance-making it optimal for cost-constrained, high-reliability motor control without floating-point acceleration. Versus TMS320F28052QPQ, it delivers double the Flash and full CLA-equivalent analog feature set for enhanced loop fidelity.

FAQ
What is the operating temperature range for the TMS320F28054FPNQ?
The TMS320F28054FPNQ is AEC Q100 Grade 1 qualified and rated for continuous operation from –40°C to +125°C ambient temperature. This specification applies to the full device-including CPU, peripherals, ADC, and analog front end-and is validated per automotive reliability standards for under-hood deployment.
Does the TMS320F28054FPNQ include a programmable gain amplifier (PGA)?
Yes, the TMS320F28054FPNQ integrates four programmable gain amplifiers (PGAs) with discrete gain settings of approximately 3, 6, or 11. These PGAs are part of the analog front end and connect directly to ADC input channels and comparator inputs-enabling on-chip signal conditioning without external op-amps.
Is the TMS320F28054FPNQ pin-compatible with other F2805x devices?
Yes, the TMS320F28054FPNQ shares the same 80-pin LQFP (PN) package and pinout with all members of the F2805x family-including TMS320F28055PN, TMS320F28053PN, and TMS320F28052QPQ-allowing PCB reuse across variants with differing Flash, CLA, or analog resource configurations.
What serial communication interfaces does the TMS320F28054FPNQ support?
The TMS320F28054FPNQ supports three SCI/UART modules, one SPI module, one I²C bus controller, and one enhanced CAN (eCAN) 2.0B controller. All interfaces operate at full CPU clock speed and include dedicated DMA channels and FIFO buffers for deterministic real-time data handling.
How is security implemented in the TMS320F28054FPNQ?
The TMS320F28054FPNQ implements dual-zone security with 128-bit encryption keys, protecting on-chip Flash, SARAM, OTP, and Secure ROM. Code execution is restricted to secure zones, and unauthorized read/write access triggers permanent lockout-preventing firmware reverse-engineering and ensuring IP protection in production deployments.
