Product details
Overview
TMS320F28027FPTQ from Texas Instruments is a 60-MHz C28x-core 32-bit real-time control microcontroller in 48-pin LQFP package, featuring 32KB flash, 6KB SARAM, 8 ePWM channels with 4 high-resolution outputs, 12-bit ADC (3 MSPS, 7 channels), and integrated comparators - deployed in motor drives, solar inverters, and industrial AC-DC power stages.
For engineers reviewing the TMS320F28027FPTQ datasheet, TMS320F28027FPTQ pinout, TMS320F28027FPTQ application, or TMS320F28027FPTQ equivalent, key selection criteria include CPU clock speed (60 MHz), HRPWM channel count (4), ADC resolution/speed (12-bit/3 MSPS), AEC Q100 qualification (-40°C to 125°C), and InstaSPIN-FOC™ enablement for sensorless FOC implementation.
Technical Context
The TMS320F28027FPTQ implements a Harvard-architecture C28x CPU with atomic operations, fast interrupt response, and unified memory model optimized for deterministic real-time control loops. Its peripheral set includes three 32-bit CPU timers, PIE-integrated interrupt handling, and dual-sample-and-hold ADC for synchronized sampling across multiple channels.
Control-specific peripherals include ePWM modules with trip-zone protection, HRPWM for sub-nanosecond edge placement, analog comparators with internal 10-bit references routed directly to PWM outputs, and on-chip VREG enabling single 3.3-V rail operation - all supporting closed-loop actuation in motor and power conversion systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C28x 32-bit fixed-point, 60 MHz (16.67-ns cycle time) - enables sub-1-µs control loop execution for high-bandwidth motor current regulation. |
| Flash Memory | 32 KB × 16-bit - sufficient for full InstaSPIN-FOC™ firmware plus application logic in compact motor drive designs. |
| ePWM Channels | 8 channels (ePWM1–ePWM4), each with independent 16-bit timer - supports 3-phase inverter + auxiliary timing (e.g., gate driver dead-time, synchronization). |
| HRPWM Outputs | 4 outputs (ePWM1A/2A/3A/4A) with 150-ps resolution - enables precise dual-edge modulation for resonant LLC or high-frequency DC-DC control. |
| ADC Performance | 12-bit, 3 MSPS, 7 input channels, dual sample-and-hold - allows simultaneous voltage/current sensing per switching cycle in 20-kHz+ PFC or inverter stages. |
| Operating Temp | –40°C to +125°C (AEC Q100 qualified) - validated for under-hood automotive traction inverters and industrial motor drives with extended thermal margins. |
| Package | 48-pin LQFP (7.0 mm × 7.0 mm) - surface-mount compatible with automated assembly and thermally adequate for ≤3W dissipation in enclosed enclosures. |
Pinout & Package
Package: 48-pin Low-Profile Quad Flatpack (LQFP), 7.0 mm × 7.0 mm body size, 0.5-mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 32, 44) | Digital supply rail | 3.3-V nominal input powering CPU, memory, and digital peripherals; requires local 100-nF decoupling per pin. |
| VDDA (Pin 11), VSSA (Pin 12) | Analog supply/ground | Separate 3.3-V analog domain for ADC and comparators; must be filtered independently to maintain 12-bit linearity. |
| GPIO0/EPWM1A (Pin 29) | Primary PWM output | High-side gate drive signal for phase-A leg; supports trip-zone fault injection via TZ1/TZ2/TZ3 inputs. |
| ADCINA0/VREFHI (Pin 10) | ADC reference input | External high-reference input; when unused, must be tied to VDDA to avoid floating node affecting ADC accuracy. |
| X1/X2 (Pins 45/46) | Crystal oscillator interface | Supports 1–20 MHz quartz crystal; X1 is input, X2 is output - enables jitter-free system clock without external oscillator component. |
| JTAG (TCK/TMS/TDI/TDO/TRST) | Debug interface | Pins 38/36/35/37/2 - standard IEEE 1149.1 boundary-scan; TRST requires external 2.2-kΩ pulldown for functional mode stability. |
Key Features
| Feature | Design Value |
|---|---|
| InstaSPIN-FOC™ Enablement | Factory-programmed ROM-based field-oriented control algorithm - eliminates need for external position sensors and reduces BOM cost in BLDC/PMSM drives. |
| Code Security Module | 128-bit encrypted key + lock mechanism protecting flash/SARAM/OTP - prevents firmware reverse engineering in commercial motor control IP. |
| Integrated Power Regulation | On-chip 1.8-V VREG powered from 3.3-V rail - removes external LDO requirement, simplifies power tree, and supports single-rail board design. |
| Enhanced Peripheral Integration | SCI (UART), SPI, I²C, eCAP, and temperature sensor on-die - enables direct communication with host MCU, gate drivers, and thermal monitoring without external ICs. |
| Low-Power Operation | No power sequencing required; brown-out reset (BOR) and POR built-in - ensures robust startup in variable-line industrial AC-DC supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28027PT | Same core, 60 MHz, 32KB flash, but lacks InstaSPIN-FOC™ ROM and AEC Q100 qualification. | Targeted at industrial motor drives where automotive qualification and embedded FOC are not required. | Select when cost sensitivity outweighs need for sensorless FOC acceleration or automotive compliance. |
| TMS320F28027F-Q1 | Identical InstaSPIN-FOC™ and AEC Q100 features, but offered in 38-pin TSSOP (DA) package instead of 48-pin LQFP (PT). | Preferred for space-constrained automotive ECUs where PCB area is limited and fewer GPIOs suffice. | Choose for automotive applications requiring same functionality in smaller footprint, accepting reduced I/O count (20 vs. 22 GPIO). |
Compared with TMS320F28027PT and TMS320F28027F-Q1, the TMS320F28027FPTQ uniquely combines AEC Q100 qualification, InstaSPIN-FOC™ firmware, and 48-pin LQFP packaging - making it optimal for production automotive inverters needing full I/O access and certified reliability.

FAQ
What is the maximum operating frequency of the TMS320F28027FPTQ?
The TMS320F28027FPTQ operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time.

The TMS320F28027FPTQ uses a 48-pin Low-Profile Quad Flatpack (LQFP) package with 7.0 mm × 7.0 mm body size and 0.5-mm pitch. This matches the "PT" suffix in the part number and is documented in TI's Mechanical, Packaging, and Orderable Information section (SPRS523P, page 125). It provides 22 multiplexed GPIO pins and full peripheral pinout access.
Is the TMS320F28027FPTQ qualified for automotive applications?
Yes, the "Q" suffix in TMS320F28027FPTQ denotes AEC Q100 qualification for automotive applications, with guaranteed operation from –40°C to +125°C. This qualification covers stress testing, reliability, and failure mechanisms per automotive standards - explicitly stated in TI's Device Comparison table (SPRS523P, Table 6-1) and supported by TI's automotive product documentation.
How much on-chip memory does the TMS320F28027FPTQ include?
The TMS320F28027FPTQ integrates 32 KB of on-chip flash memory (16-bit words), 6 KB of SARAM (single-cycle access), 8 KB of boot ROM, and 1 KB of one-time programmable (OTP) ROM.
