Product details
Overview
TMS320F280260DAS from Texas Instruments is a 50-MHz C28x-core Piccolo™ microcontroller in a 38-pin TSSOP package, featuring 8K × 16-bit on-chip flash, 4K × 16-bit SARAM, and integrated ePWM (6-channel), ADC (6-channel, 1.25 MSPS), and serial peripherals (SCI/SPI/I²C). It operates from a single 3.3-V supply with internal voltage regulation and is designed for real-time motor control in compact industrial drives.
For engineers reviewing the TMS320F280260DAS datasheet, TMS320F280260DAS pinout, TMS320F280260DAS application, or TMS320F280260DAS equivalent, this device delivers deterministic 20-ns instruction cycle timing, code-security module protection, dual zero-pin oscillators, and GPIO multiplexing for space-constrained embedded control where analog integration, PWM precision, and flash-based firmware update capability are critical.
Technical Context
The TMS320F280260DAS implements the TMS320C28x 32-bit fixed-point CPU with Harvard bus architecture, atomic 16×16/32×32 MAC operations, and 8-level protected pipeline enabling real-time interrupt response with automatic context save. Its memory map includes 8K flash (2 sectors), 4K SARAM (M0/M1), 2K L0 SARAM, 8K boot ROM, and 1K OTP - all mapped to both program and data space with configurable wait-states.
Peripheral integration centers on three 32-bit CPU timers, six ePWM channels with independent 16-bit timers and trip-zone inputs, one eCAP module, and a 12-bit ADC with 6 input channels, 1.25 MSPS sampling rate, and dual sample-and-hold - all synchronized via the PIE interrupt controller and accessible through peripheral frames 0–2 with write/read protection modes.
