Texas Instruments TMS320F28027FPTTR

Overview

TMS320F28027FPTTR from Texas Instruments is a 60-MHz C28x-core real-time control microcontroller in 48-pin LQFP package, featuring 32 KB flash, 6 KB SARAM, 8 ePWM channels with 4 high-resolution outputs, 12-bit ADC (3 MSPS, 7 channels), and integrated comparators for closed-loop motor control. It operates from a single 3.3-V supply and targets digital power and inverter applications.

For engineers reviewing the TMS320F28027FPTTR datasheet, TMS320F28027FPTTR pinout, TMS320F28027FPTTR application, or TMS320F28027FPTTR equivalent, key selection criteria include CPU clock speed (60 MHz), HRPWM channel count (4), ADC resolution/speed (12-bit/3 MSPS), GPIO count (22 multiplexed), and InstaSPIN-FOC™ enablement for sensorless FOC deployment.

Technical Context

The TMS320F28027FPTTR implements the TMS320C28x 32-bit CPU core with Harvard architecture, atomic instructions, and unified memory model, enabling deterministic real-time execution. Its clock system integrates dual zero-pin oscillators, crystal oscillator support, and PLL-based frequency synthesis to deliver stable 60-MHz SYSCLK from internal or external sources.

Peripheral integration centers on control-specific functions: ePWM modules with independent 16-bit timers and dual-edge HRPWM capability, PIE-interrupt routing for low-latency response, and analog subsystem combining 12-bit ADC with dual comparators and internal 10-bit references-enabling direct comparator-to-PWM trip zone triggering without CPU intervention.

FAQ

What is the maximum operating frequency of the TMS320F28027FPTTR?

The TMS320F28027FPTTR operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This speed is achieved using the on-chip PLL with either internal zero-pin oscillators or an external crystal (X1/X2) or clock source (XCLKIN). The device supports multiple clock configurations-including SYSCLKOUT division ratios-for flexible peripheral timing alignment.

Does the TMS320F28027FPTTR support sensorless motor control out of the box?

Yes, the TMS320F28027FPTTR is InstaSPIN-FOC™-enabled, meaning it ships with factory-programmed ROM-based motor identification and field-oriented control firmware. Engineers can deploy sensorless FOC on supported motors immediately using TI's GUI tools-no custom coding required. The ADC, comparators, and HRPWM are preconfigured to execute real-time torque and flux loops without CPU overhead.

How many analog inputs does the TMS320F28027FPTTR ADC support?

The TMS320F28027FPTTR features a 12-bit analog-to-digital converter with 7 input channels in Group A (ADCINA0–ADCINA6) and 7 in Group B (ADCINB0–ADCINB6), though only 7 total are accessible in the 48-pin LQFP package. The device supports simultaneous sampling across both groups using dual sample-and-hold circuits, enabling accurate three-phase current reconstruction in motor control applications.

Is the TMS320F28027FPTTR pin-compatible with other F2802x devices in LQFP-48?

Yes, the TMS320F28027FPTTR shares identical pinout and electrical characteristics with all F2802x family members in the PT (LQFP-48) package-including TMS320F28027PT, TMS320F28026FPTTR, and TMS320F28023PT. Signal assignments, power pin locations, and JTAG interface mapping are fully consistent, enabling hardware reuse across variants when firmware and memory requirements align.

What security features protect firmware on the TMS320F28027FPTTR?

The TMS320F28027FPTTR includes a dedicated Code Security Module with 128-bit encryption key storage and lock bits that prevent read-out of flash, SARAM, and OTP memory. Once secured, debug access (JTAG) is disabled, and unauthorized firmware extraction or modification is blocked at the hardware level-meeting industrial IP protection requirements without external secure elements.
