Overview
TMS320F280270 from Texas Instruments is a 50-MHz C28x-core Piccolo™ microcontroller in a 48-pin LQFP package, featuring 16KB on-chip flash, 4KB SARAM, dual 10-bit analog comparators, 6-channel 12-bit ADC (1.25 MSPS), and three ePWM modules supporting up to six PWM outputs-designed for real-time motor control in compact industrial drives.
For engineers reviewing the TMS320F280270 datasheet, TMS320F280270 pinout, TMS320F280270 application, or TMS320F280270 equivalent, this page delivers verified specifications, validated package mapping, confirmed peripheral integration (ePWM/ADC/comparators), and precise alternative part comparisons-enabling rapid selection for cost-sensitive, space-constrained embedded control designs.
Technical Context
The TMS320F280270 implements a Harvard-architecture 32-bit C28x CPU with 20-ns instruction cycle time, atomic MAC operations, and unified memory programming model. Its memory subsystem includes 16KB flash (4×4KB sectors), 4KB SARAM (M0/M1/L0), 8KB boot ROM, and 1KB OTP-all mapped to both program and data space with configurable wait-states.
Real-time control is enabled by three independent 32-bit CPU timers, six ePWM channels with TZ fault protection and EPWMSYNC I/O, one eCAP module, and integrated analog peripherals: dual comparators with internal 10-bit DAC references routed directly to PWM trip zones, and a 12-bit ADC with 800-ns conversion time and dual sample-and-hold.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280260PT | Same 48-pin LQFP package, 50-MHz C28x core, but reduced flash (8KB) and no analog comparators | Lacks hardware overcurrent protection path; requires external comparator or software-based fault handling | Select when cost sensitivity outweighs need for integrated comparator-based safety or when firmware size ≤8KB |
| TMS320F28035PT | Higher-tier Piccolo with 128KB flash, CLA co-processor, enhanced ePWM (trip-zones + HRPWM), and 16-channel ADC | Supports complex multi-motor systems and advanced observer-based control; CLA offloads CPU for higher loop rates | Choose when design requires >16KB flash, >6 PWM channels, or CLA-accelerated math (e.g., predictive current control) |
Compared with TMS320F280260PT, the TMS320F280270 provides essential hardware safety via dual comparators and double the flash for robust field-upgradable firmware; versus TMS320F28035PT, it trades CLA and expanded peripherals for lower BOM cost and smaller footprint-ideal for single-motor, cost-optimized industrial drives.

FAQ
What is the maximum operating frequency and instruction cycle time of the TMS320F280270?
The TMS320F280270 operates at a maximum system clock frequency of 50 MHz, delivering a 20-ns instruction cycle time. This performance level enables deterministic execution of high-frequency control loops-such as 20-kHz PWM carrier generation with margin for communication and supervisory tasks-while maintaining low latency for interrupt-driven events like fault detection.
Does the TMS320F280270 include on-chip analog comparators, and how are they used in motor control?
Yes, the TMS320F280270 integrates two analog comparators with internal 10-bit DAC references. Their outputs (COMP1OUT/COMP2OUT) connect directly to ePWM trip-zone (TZ) inputs, enabling hardware-level, sub-microsecond disabling of PWM outputs upon overcurrent or overvoltage detection-bypassing CPU latency and ensuring functional safety in motor drive applications.
What memory resources are available on the TMS320F280270, and how are they organized?
The TMS320F280270 includes 16KB of on-chip flash (4×4KB sectors), 4KB of SARAM (M0/M1/L0), 8KB of boot ROM, and 1KB of OTP. All memory blocks map to both program and data space. Flash supports secure code storage with 128-bit password protection; boot ROM contains preprogrammed math tables and bootloader options for SCI/SPI/I²C.
Which communication interfaces does the TMS320F280270 support, and what are their key capabilities?
The TMS320F280270 supports one SCI (UART), one SPI, and one I²C interface-each with 4-level FIFOs. SCI enables host debugging or serial command interfaces; SPI supports fast configuration of external DACs or sensors; I²C connects to temperature sensors or display controllers. All are multiplexed onto GPIO pins and managed via the GPIO MUX block.
What package options and temperature grades are offered for the TMS320F280270?
The TMS320F280270 is available in the PT package: a 48-pin LQFP (7 mm × 7 mm, 0.5-mm pitch). It is qualified for industrial temperature range (–40°C to 105°C) and extended temperature range (–40°C to 125°C), making it suitable for demanding environments including eBike controllers and HVAC blower drives.
