Texas Instruments TMS320F280260PTS

Overview

TMS320F280260PTS from Texas Instruments is a 50-MHz C28x-core Piccolo™ microcontroller in a 48-pin LQFP package, featuring 8K × 16-bit on-chip flash, 3K × 16-bit SARAM, 6-channel 12-bit ADC with 800-ns conversion time, and three 32-bit CPU timers. It integrates ePWM (6 channels), eCAP (1 input), SPI, SCI, I²C, and on-chip voltage regulation for single 3.3-V supply operation in motor control and power conversion systems.

For engineers reviewing the TMS320F280260PTS datasheet, TMS320F280260PTS pinout, TMS320F280260PTS application, or TMS320F280260PTS equivalent, this page delivers verified functional specifications, validated package mapping, confirmed peripheral integration, and real-world use context for embedded control design, BOM validation, and migration planning.

Technical Context

The TMS320F280260PTS implements the TMS320C28x 32-bit fixed-point CPU with Harvard bus architecture, atomic operations, and 8-level protected pipeline-enabling deterministic real-time interrupt response with automatic context save. Its memory map includes dual-mapped L0 SARAM (1K × 16), boot ROM (8K × 16), OTP (1K × 16), and flash organized in two 4K × 16 sectors.

Peripheral integration follows TI's standardized peripheral bus architecture: ePWM modules support independent 16-bit timers and trip-zone inputs; the ADC uses ratio-metric VREFHI/VREFLO references and supports dual sample-and-hold; and the code-security module enforces 128-bit password protection across flash, SARAM, and OTP blocks.

FAQ

What is the maximum operating frequency of the TMS320F280260PTS?

The TMS320F280260PTS operates at a maximum CPU frequency of 50 MHz, corresponding to a 20-ns instruction cycle time. This speed is supported across its full industrial temperature range (–40°C to 105°C) and requires proper decoupling and PCB layout per TI's design guidelines. The TMS320F280260PTS achieves this performance using an on-chip PLL with dynamic ratio changes and internal zero-pin oscillators.

Does the TMS320F280260PTS include an integrated ADC, and what are its key specs?

Yes, the TMS320F280260PTS integrates a 12-bit analog-to-digital converter with six input channels, 1.25 MSPS sampling rate, and 800-ns conversion time. It supports ratio-metric referencing using internal VREFHI/VREFLO pins and features dual sample-and-hold capability. The ADC is directly accessible by the C28x CPU with low-latency interface-enabling precise current/voltage sensing in motor control loops.

How does the code-security module function on the TMS320F280260PTS?

The TMS320F280260PTS implements a hardware-based code-security module that uses a 128-bit password to lock access to on-chip flash, SARAM, and OTP memory. Once enabled, unauthorized read attempts return zeros, and protected memory regions cannot be accessed via JTAG or boot ROM. Password programming is irreversible and must be performed carefully-TI provides dedicated tools and procedures for secure firmware deployment on the TMS320F280260PTS.

Can the TMS320F280260PTS operate from a single 3.3-V supply?

Yes, the TMS320F280260PTS is designed for single-rail 3.3-V operation. Its integrated voltage regulator supplies core logic, eliminating external power sequencing requirements. Both VDD (core) and VDDIO (I/O) rails must be tied to 3.3 V, with VDDIO maintained within ±0.3 V of VDD. This simplifies power design and reduces external component count-key for compact, cost-sensitive applications like eBike controllers.

What communication interfaces are available on the TMS320F280260PTS?

The TMS320F280260PTS includes one SCI (UART), one SPI, and one I²C module-all accessible via multiplexed GPIO pins. Each peripheral features a 4-deep FIFO to reduce CPU overhead, and all support standard protocols without external transceivers. These interfaces enable host communication, sensor interfacing, and firmware updates-making the TMS320F280260PTS suitable for networked industrial devices and smart appliances.
