Product details
Overview
TMS320F28027PTR from Texas Instruments is a 60-MHz C28x-core 32-bit real-time control microcontroller in 48-pin LQFP packaging, featuring 32KB flash, 6KB SARAM, 8-channel ePWM with 4 high-resolution outputs, 12-bit 3-MSPS ADC (7 channels), and integrated comparators - deployed in motor control power stages and digital power converters.
For engineers reviewing the TMS320F28027PTR datasheet, TMS320F28027PTR pinout, TMS320F28027PTR application, or TMS320F28027PTR equivalent, key selection criteria include CPU clock speed (60 MHz), on-chip analog integration (ADC + comparators), PWM resolution capability (HRPWM), single 3.3-V supply operation, and industrial temperature range (–40°C to 105°C).
Technical Context
The TMS320F28027PTR implements a Harvard-architecture C28x CPU with atomic instructions, fast interrupt response, and unified memory model optimized for deterministic real-time control loops. It integrates dual 12-bit ADC groups (Group A: 7 channels, Group B: 7 channels), each with dual sample-and-hold and configurable VREFHI/VREFLO references.
Its control peripherals include eight ePWM modules (four with HRPWM capability enabling dual-edge modulation), four eCAP inputs, one I2C, one SPI, and one SCI/UART - all coordinated via a Peripheral Interrupt Expansion (PIE) block supporting nested interrupts with low latency.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28026PT | Same 48-pin LQFP package, 60-MHz C28x core, but only 16KB flash and 6KB SARAM; identical peripheral set except no HRPWM | Lacks high-resolution PWM - unsuitable for sub-100-ns timing-critical digital power topologies | Select when cost-sensitive motor control requires full ePWM count but not HRPWM precision |

FAQ
What is the maximum operating frequency of the TMS320F28027PTR?
The TMS320F28027PTR operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This speed is achieved using the internal zero-pin oscillator or an external clock source, with PLL configuration enabling stable high-speed execution for real-time control loops. The TMS320F28027PTR maintains full peripheral functionality at this clock rate, including simultaneous ADC sampling and HRPWM updates.
Does the TMS320F28027PTR support hardware-based fault protection?
Yes, the TMS320F28027PTR supports hardware fault protection via its integrated analog comparators and trip-zone (TZ) logic. COMP1OUT and COMP2OUT can be directly routed to ePWM modules' TZ1–TZ3 inputs, triggering immediate PWM blanking within one CPU cycle - typically <100 ns - without software intervention. This capability is confirmed in the device's functional block diagram and signal description tables for the 48-pin PT package.
What analog-to-digital converter (ADC) performance does the TMS320F28027PTR provide?
The TMS320F28027PTR features a 12-bit ADC with 3-MSPS conversion rate, dual sample-and-hold, and two independent groups (A and B) totaling 14 input channels. Group A provides 7 channels (ADCINA0–ADCINA7), Group B provides 7 channels (ADCINB1–ADCINB7), with fixed 0–3.3-V full-scale range and ratio-metric reference support via VREFHI/VREFLO pins. This ADC architecture enables simultaneous sampling for current/voltage feedback in three-phase motor control.
Is the TMS320F28027PTR pin-compatible with other F2802x family members in the same package?
Yes, the TMS320F28027PTR is pin-compatible with other 48-pin LQFP variants in the F2802x family, including TMS320F28026PT and TMS320F28023PT. All share identical pin assignments, electrical characteristics, and mechanical dimensions per TI's Device Information table. However, peripheral enablement differs - for example, HRPWM is present on TMS320F28027PTR but not on TMS320F28023PT - so firmware must verify feature availability before migration.
What debug interfaces are supported by the TMS320F28027PTR?
The TMS320F28027PTR supports IEEE 1149.1 JTAG debugging via five dedicated pins (TCK, TMS, TDI, TDO, TRST) multiplexed with GPIO38, GPIO36, GPIO35, GPIO37, and GPIO12 respectively. It also provides real-time emulation features including hardware breakpoints, analysis points, and trace-capable debug through the C2000 Debug Probe interface. These capabilities are documented in Section 4 (Functional Block Diagram) and Section 7.2.1 (Signal Descriptions) of the official datasheet.
