Product details
Overview
TMS320F280270 from Texas Instruments is a 50-MHz C28x-core Piccolo™ microcontroller in a 38-pin TSSOP (DA) package, featuring 16KB on-chip flash, 4KB SARAM, 6-channel 12-bit ADC with 800-ns conversion time, three 32-bit CPU timers, and six ePWM channels-designed for real-time motor control in compact industrial drives.
For engineers reviewing the TMS320F280270 datasheet, TMS320F280270 pinout, TMS320F280270 application, or TMS320F280270 equivalent, key selection criteria include flash size (16K × 16), dual comparators (TMS320F280270 only), 3.3-V single-rail operation, and DA-package GPIO count (20 shared I/O pins).
Technical Context
The TMS320F280270 implements a Harvard-architecture 32-bit C28x CPU with 20-ns instruction cycle, atomic 16×16/32×32 MAC operations, and pipelined memory access enabling simultaneous program fetch, data read, and data write. It integrates a dedicated peripheral bus (Peripheral Frame 0/1/2) with PIE interrupt expansion supporting all peripherals.
Its analog subsystem includes a temperature sensor, dual independent comparators with internal 10-bit DAC references, and an ADC with ratio-metric VREFHI/VREFLO support-directly routable to ePWM trip-zone logic for hardware-fast overcurrent protection in motor gate drivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280230 | Same 38-pin DA package, 40-MHz CPU, 16KB flash, but only 1 comparator and no dual-sample-and-hold ADC | Limited to single-fault-zone motor control; lacks hardware redundancy for safety-critical overcurrent detection | Select when cost sensitivity outweighs need for dual comparators and 50-MHz performance headroom |
| TMS320F280270PT | Same core/peripherals, but 48-pin LQFP (PT) package with 22 GPIO and 8 ADC channels | Enables higher peripheral count (e.g., dual SPI + SCI + I²C simultaneously) and thermal margin in convection-cooled designs | Select when board layout allows larger footprint and additional analog/digital I/O is required for system expansion |
Compared with TMS320F280230 and TMS320F280270PT, the TMS320F280270 uniquely balances 50-MHz deterministic control, dual hardware comparators, and minimal 38-pin TSSOP footprint-making it optimal for space-constrained, single-fault-zone industrial motor drives where BOM cost and PCB area are primary constraints.

FAQ
What is the maximum operating frequency of the TMS320F280270?
The TMS320F280270 operates at a maximum CPU frequency of 50 MHz, delivering a 20-ns instruction cycle time. This speed is achieved using an internal PLL with dynamic ratio adjustment capability, allowing the device to maintain precise timing across varying thermal and voltage conditions while executing real-time motor control algorithms. The TMS320F280270 maintains full peripheral functionality-including ADC sampling, ePWM updates, and interrupt servicing-at this rated frequency.
Does the TMS320F280270 support hardware-based fault protection?
Yes, the TMS320F280270 includes two integrated analog comparators with programmable hysteresis and direct routing to ePWM trip-zone (TZ) inputs. This enables sub-microsecond hardware fault response-bypassing CPU intervention-to shut down PWM outputs during overcurrent, overvoltage, or thermal events. The comparators accept internal 10-bit DAC references and can be configured for windowed or threshold detection, making the TMS320F280270 suitable for IEC 61800-5-2 compliant motor drives.
How much on-chip memory does the TMS320F280270 provide?
The TMS320F280270 provides 16K × 16 words of on-chip flash memory (organized in four 4K sectors), 4K × 16 words of SARAM (split across M0/M1/L0 blocks), 1K × 16 OTP memory, and an 8K × 16 boot ROM. All memory blocks are mapped to both program and data space, supporting unified C/C++ development. Flash and OTP include 128-bit password security, and wait-states are configurable to optimize performance across different SYSCLK frequencies.
What communication interfaces are integrated into the TMS320F280270?
The TMS320F280270 integrates one SCI (UART), one SPI, and one I²C module-each with 4-level FIFOs to reduce CPU overhead. These peripherals are accessible via GPIO multiplexing, with dedicated pins in the 38-pin DA package. The SCI supports auto-baud detection and LIN-compatible break detection; SPI includes master/slave modes and configurable phase/polarity; I²C complies with standard-mode (100 kbps) and fast-mode (400 kbps) specifications-all verified in TI's SPRS810B datasheet.
Is the TMS320F280270 pin-compatible with other F2802x0 devices?
The TMS320F280270 is pin-compatible with the TMS320F280230 in the 38-pin DA package, sharing identical pin assignments, electrical characteristics, and peripheral mappings. However, it is not pin-compatible with 48-pin PT variants (e.g., TMS320F280270PT) due to differing pin counts and signal allocations. Functional differences-such as dual comparators and 50-MHz operation-are implemented within the same DA-package footprint, enabling drop-in replacement where performance and feature requirements align.
