Texas Instruments TMS320F28027FPTT

Overview

TMS320F28027FPTT from Texas Instruments is a 32-bit C28x-core microcontroller optimized for real-time motor control and digital power applications, operating at 60 MHz (16.67-ns cycle time), featuring 32 KB on-chip Flash, 6 KB SARAM, 8-channel ePWM with 4 high-resolution outputs, 12-bit ADC (3 MSPS, 7 channels), and integrated comparators with DACs. It serves as the central control unit in inverter gate-drive timing and closed-loop current regulation.

For engineers reviewing the TMS320F28027FPTT datasheet, TMS320F28027FPTT pinout, TMS320F28027FPTT application, or TMS320F28027FPTT equivalent, key selection criteria include its 48-pin LQFP package, 60-MHz deterministic execution, InstaSPIN-FOC™ enablement, dual-comparator routing to PWM, and single 3.3-V supply operation without sequencing.

Technical Context

The TMS320F28027FPTT implements a Harvard-architecture C28x CPU with atomic instructions and fast interrupt response, supporting deterministic real-time control loops. Its peripheral set includes three 32-bit CPU timers, PIE-integrated interrupt handling, and dedicated HRPWM modules capable of dual-edge modulation for precise frequency and duty-cycle control.

On-chip analog integration comprises a 12-bit ADC with 216.67-ns conversion time and ratio-metric reference support, two analog comparators with internal 10-bit DACs directly routable to ePWM trip zones, and an internal voltage regulator enabling single-rail 3.3-V operation - eliminating external LDO requirements in space-constrained motor drive designs.

FAQ

What is the maximum operating frequency of the TMS320F28027FPTT?

The TMS320F28027FPTT operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This frequency 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 maintains full specification compliance - including ADC timing, PWM resolution, and interrupt latency - across its entire temperature range (–40°C to 105°C).

Does the TMS320F28027FPTT support InstaSPIN-FOC™ out of the box?

Yes, the TMS320F28027FPTT is factory-enabled for InstaSPIN-FOC™, with the motor control firmware library pre-programmed into ROM and accessible via TI's MotorControl SDK. No additional license or flash programming is required to deploy sensorless FOC on PMSM or BLDC motors - the TMS320F28027FPTT automatically identifies motor parameters and tunes control loops during runtime commissioning.

How many high-resolution PWM outputs does the TMS320F28027FPTT provide?

The TMS320F28027FPTT provides four high-resolution PWM (HRPWM) outputs - EPWM1A, EPWM2A, EPWM3A, and EPWM4A - each capable of 150-ps resolution for fine edge placement. These outputs operate independently of standard ePWM timing and support dual-edge modulation, enabling precise frequency and duty-cycle control essential for SiC/GaN-based high-frequency inverters.

What analog peripherals are integrated into the TMS320F28027FPTT?

The TMS320F28027FPTT integrates a 12-bit, 3-MSPS ADC with 7 input channels (Group A), a second 12-bit ADC group (Group B) with 6 inputs, two analog comparators with internal 10-bit DACs, an on-chip temperature sensor, and dedicated analog supply rails (VDDA/VSSA). All analog blocks share a common 3.3-V reference and support ratio-metric operation using VREFHI/VREFLO pins.

Is the TMS320F28027FPTT pin-compatible with other F2802x devices in the same package?

Yes, the TMS320F28027FPTT is fully pin-compatible with all 48-pin LQFP variants in the F2802x family, including TMS320F28026FPTT and TMS320F28023PT. Signal mapping, power pin locations, JTAG interface, and peripheral multiplexing are identical across these parts - enabling drop-in replacement for memory- or feature-downgraded versions without PCB redesign.
