Product details
Overview
TMS320F28030PNT from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated analog peripherals, designed for closed-loop motor and power control. It features 16 kB flash, 6 kB SARAM, 3× 32-bit CPU timers, 14 ePWM channels, 16-channel 12-bit ADC (2 MSPS), and on-chip comparators - enabling single-chip implementation of digital PFC, BLDC commutation, and inverter gate drive in DC/DC converters and solar microinverters.
For engineers reviewing the TMS320F28030PNT datasheet, TMS320F28030PNT pinout, TMS320F28030PNT application, or TMS320F28030PNT equivalent, key selection considerations include its LQFP-80 package, 3.3-V single-supply operation, CLA-free architecture (vs. F28033/F28035), absence of HRCAP/eQEP modules, and compatibility with TI's C2000™ real-time control ecosystem including InstaSPIN-FOC reference designs.
Technical Context
The TMS320F28030PNT implements a Harvard-architecture C28x CPU executing at 60 MHz (16.67 ns cycle time) with unified memory mapping and atomic instruction support. Its peripheral set centers on deterministic real-time control: ePWM modules with trip-zone protection, ADC with dual sample-and-hold and ratio-metric VREFHI/VREFLO references, and three independent 32-bit CPU timers for scheduling and synchronization.
It integrates no Control Law Accelerator (CLA), distinguishing it from F28033/F28035 variants, and omits high-resolution peripherals (HRCAP, eQEP) and LIN/eCAN interfaces found in higher-tier members. The device relies on GPIO-multiplexed analog inputs (ADCINA0–7, ADCINB0–7) and comparator outputs routed directly to PWM trip logic for fast overcurrent response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C28x 32-bit fixed-point, 60 MHz - enables sub-μs interrupt latency and deterministic loop execution for <10-μs current control cycles. |
| Flash Memory | 16 KB × 16-bit - sufficient for dual-bank firmware updates and field-programmable motor control algorithms. |
| RAM | 6 KB × 16-bit SARAM - supports real-time variable storage and coefficient tables without wait states. |
| ADC | 12-bit, 16-channel, 2 MSPS - captures voltage/current feedback with 500 ns conversion time for synchronous sampling across multiple phases. |
| ePWM Channels | 14 independent channels - supports 3-phase inverter + auxiliary control (e.g., PFC stage, fan control) with dead-time insertion and fault protection. |
| Package & Temp | LQFP-80 (12 mm × 12 mm), –40°C to 105°C - suitable for industrial ambient conditions and standard PCB assembly processes. |
| Supply | Single 3.3-V rail, internal VREG - eliminates external LDOs and power sequencing complexity in cost-sensitive power modules. |
Pinout & Package
Package: PN (LQFP-80), 12.0 mm × 12.0 mm body size, 0.5-mm pitch, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDIO, VDDA | Power supply rails | VDD = core/digital I/O (3.3 V); VDDIO = I/O buffer supply (3.3 V); VDDA = analog domain (3.3 V) - decoupling required per datasheet layout guidelines. |
| VSS, VSSA, VREFLO | Ground and reference return | VSS = digital ground; VSSA = analog ground; VREFLO = ADC low reference - separate AGND/DGND routing critical for <12-bit ADC accuracy. |
| GPIO0–GPIO44 | Configurable digital I/O | 45 total pins, multiplexed with peripherals (ePWM, eCAP, SPI, etc.) - default GPIO mode at reset; pullups enabled on non-PWM pins. |
| ADCINA0–7, ADCINB0–7 | Analog input channels | 16 differential-capable inputs; ADCINA0 doubles as VREFHI - requires external filtering for noise immunity in motor current sensing. |
| X1, X2 | Crystal oscillator terminals | Supports external crystal (1–20 MHz) or ceramic resonator; internal oscillators available if external clock not used. |
| TCK, TMS, TDI, TDO, TRST | JTAG debug interface | IEEE 1149.1 compliant; TRST requires external 2.2-kΩ pulldown - enables real-time emulation and flash programming via XDS100v3/XDS200. |
Key Features
| Feature | Design Value |
|---|---|
| Code-compatible C28x architecture | Maintains binary compatibility with legacy F2802x/F2800x code, reducing migration effort for existing motor control firmware. |
| Integrated analog front-end | On-chip 12-bit ADC, 3 analog comparators with 10-bit DAC references, and temperature sensor - eliminates discrete signal conditioning for basic feedback loops. |
| Deterministic ePWM subsystem | 14 channels with trip-zone inputs, dead-band generation, and EPWMSYNCI/EPWMSYNCO synchronization - ensures precise timing alignment across multi-phase inverters. |
| Single-rail 3.3-V operation | Internal voltage regulator eliminates need for external 1.8-V supply; no power sequencing required - simplifies BOM and board layout. |
| Peripheral Interrupt Expansion (PIE) | Centralized vectoring for all 96+ peripheral interrupts - reduces ISR latency and enables prioritized handling of ADC EOC, PWM faults, and communication events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28031PNT | Same 60-MHz C28x core, 32 KB flash, 8 KB SARAM, but only 12 ePWM channels and 14 ADC channels - no HRCAP or eQEP. | Lower peripheral count suits simpler single-phase PFC or fan control where 14 ePWMs are unnecessary. | Select when firmware footprint exceeds 16 KB or additional RAM is needed for larger observer models. |
| TMS320F28032PNT | Same 60-MHz C28x core, 32 KB flash, 10 KB SARAM, 8 ePWM channels, 13 ADC channels - reduced I/O count (33 GPIO) and no LIN/eCAN. | Targeted at space-constrained designs like wireless charging pads where minimal peripheral integration suffices. | Choose for compact LQFP-80 layouts requiring fewer analog inputs or simplified communication (SPI-only). |
Compared with TMS320F28031PNT and TMS320F28032PNT, the TMS320F28030PNT offers the highest ePWM channel count (14) and full 16-channel ADC within the entry-level F2803x family, making it optimal for multi-function power stages where peripheral density outweighs flash/RAM expansion needs.

FAQ
What is the maximum operating frequency of the TMS320F28030PNT CPU core?
The TMS320F28030PNT features a C28x 32-bit CPU core rated for 60 MHz operation, corresponding to a 16.67 ns instruction cycle time. This frequency is achieved using the internal PLL with an external crystal or oscillator input, and is fully supported across the specified temperature range of –40°C to 105°C.
Does the TMS320F28030PNT include a Control Law Accelerator (CLA)?
No, the TMS320F28030PNT does not include a CLA. The CLA is present only in the TMS320F28033PNT and TMS320F28035PNT variants. The TMS320F28030PNT relies solely on the main C28x CPU for control law execution, which remains sufficient for many digital power and motor control applications with moderate computational load.
What package type and pin count does the TMS320F28030PNT use?
The TMS320F28030PNT is packaged in an 80-pin Low-Profile Quad Flatpack (LQFP), designated by the "PN" suffix. Its mechanical dimensions are 12.0 mm × 12.0 mm with 0.5-mm pitch, and it is RoHS-compliant. This package provides full access to all 45 GPIO pins, 16 ADC inputs, and 14 ePWM channels.
Can the TMS320F28030PNT support CAN bus communication?
No, the TMS320F28030PNT does not integrate an eCAN module. CAN functionality is available only in the TMS320F28030-Q1 (automotive-qualified) variant and higher-tier F2803x parts such as the TMS320F28033PNT and TMS320F28035PNT. For standard TMS320F28030PNT designs, external CAN transceivers with SPI-based software CAN stacks are required.
What is the ADC resolution and sampling rate of the TMS320F28030PNT?
The TMS320F28030PNT integrates a 12-bit analog-to-digital converter with 16 input channels and a maximum throughput of 2 million samples per second (MSPS). Its conversion time is 500 ns, and it supports dual sample-and-hold for simultaneous sampling - critical for accurate three-phase current reconstruction in motor control.
