Product details
Overview
TMS320F28027PTQR from Texas Instruments is a C2000™ 32-bit real-time control microcontroller featuring a 60-MHz TMS320C28x CPU, 32 KB on-chip Flash, 6 KB SARAM, 8 ePWM channels with 4 high-resolution outputs, 12-bit ADC (3 MSPS, 7 channels), and integrated comparators-designed for closed-loop motor control in industrial inverters and AC drive power stages.
For engineers reviewing the TMS320F28027PTQR datasheet, TMS320F28027PTQR pinout, TMS320F28027PTQR application, or TMS320F28027PTQR equivalent, key selection criteria include its 48-pin LQFP package, AEC-Q100 qualified temperature range (–40°C to 125°C), single 3.3-V supply operation, and support for InstaSPIN-FOC™-compatible firmware deployment in BLDC and PMSM motor drives.
Technical Context
The TMS320F28027PTQR implements a Harvard-architecture C28x core with atomic operations and fast interrupt response, enabling deterministic real-time control loops. Its peripheral set includes three 32-bit CPU timers, PIE-integrated interrupt handling, and dual-sample-and-hold ADC architecture optimized for low-latency current sensing.
Control-specific peripherals are tightly coupled: HRPWM modules support dual-edge modulation for frequency control; analog comparators route directly to PWM trip zones (TZ1–TZ3); and GPIO multiplexing enables flexible signal routing across 22 programmable I/O pins with input filtering-critical for noise-immune gate driver interfacing in power electronics.

FAQ
What is the maximum operating frequency of the TMS320F28027PTQR?
The TMS320F28027PTQR operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This clock rate is achieved using the internal PLL with either the on-chip zero-pin oscillator or an external crystal (X1/X2) or clock source (XCLKIN). The device supports multiple clock configurations, including SYSCLKOUT division for peripheral synchronization, and maintains timing integrity across its full operating temperature range of –40°C to 125°C.
Does the TMS320F28027PTQR support hardware-based fault protection?
Yes, the TMS320F28027PTQR supports hardware-based fault protection through its two analog comparators (COMP1 and COMP2), each with dedicated inputs (COMP1A/COMP1B, COMP2A/COMP2B) and outputs (COMP1OUT/COMP2OUT) routed directly to ePWM trip-zone (TZ) inputs. These comparators feature internal 10-bit DAC references and can trigger immediate PWM shutdown within one system clock cycle-enabling sub-microsecond overcurrent response without CPU intervention. This capability is confirmed in the device's functional block diagram and signal description tables.
What are the ADC performance specifications of the TMS320F28027PTQR?
The TMS320F28027PTQR integrates a 12-bit analog-to-digital converter with 3-MSPS sampling rate, 216.67-ns conversion time, and 7 input channels in Group A (ADCINA0–ADCINA6). It supports dual sample-and-hold operation, ratio-metric referencing (VREFHI/VREFLO), and fixed full-scale range of 0 to 3.3 V. The ADC interface is optimized for low overhead and latency, with direct memory access via PIE interrupts-making it suitable for high-fidelity current sensing in real-time motor control loops.
Is the TMS320F28027PTQR pin-compatible with other F2802x family members?
Yes, the TMS320F28027PTQR in the 48-pin PT LQFP package is pin-compatible with other F2802x devices offered in the same package variant-including TMS320F28026PTQR, TMS320F28023PTQR, and TMS320F28027FPTQR-as confirmed in TI's Device Comparison table (SPRS523P, Table 6-1). All share identical pin assignments, electrical characteristics, and peripheral mapping, enabling hardware reuse across performance tiers while differing only in Flash size, HRPWM count, and embedded firmware features.
What development tools are supported for the TMS320F28027PTQR?
The TMS320F28027PTQR is supported by Texas Instruments' C2000Ware software suite, Code Generation Tools (C2000 C/C++ Compiler), and CCS IDE. Hardware tools include the TMDSEMU200-U JTAG emulator, LAUNCHXL-F28027 LaunchPad development kit, and BOOSTXL-3PHGANINV for GaN-based inverter evaluation. TI also provides motor control SDKs, InstaSPIN-FOC GUI, and reference designs such as TIDA-00776 for AC-input BLDC drives-all validated for the TMS320F28027PTQR device.
