Texas Instruments TMS320F280200DAS

Overview

TMS320F280200DAS from Texas Instruments is a 32-bit C28x-core microcontroller optimized for real-time motor and power control, operating at 40 MHz (25-ns cycle time), featuring 8 kB on-chip Flash, 3 kB SARAM, 12-bit ADC with 7 channels, 8 ePWM channels, and integrated comparators with DACs - deployed in AC-input BLDC motor drives and industrial AC-DC power stages.

For engineers reviewing the TMS320F280200DAS datasheet, TMS320F280200DAS pinout, TMS320F280200DAS application, or TMS320F280200DAS equivalent, key selection criteria include CPU clock speed (40 MHz), Flash/SARAM memory allocation (8K/3K × 16), HRPWM capability, analog integration level (ADC + dual comparators), and TSSOP-38 package compatibility with thermal limits of –40°C to 125°C.

Technical Context

The TMS320F280200DAS implements a Harvard-architecture C28x CPU with atomic operations and fast interrupt response, supporting deterministic real-time control loops. Its peripheral set includes three 32-bit CPU timers, an 8-channel ePWM subsystem with high-resolution extensions (HRPWM), and a 12-bit ADC with dual sample-and-hold and ratio-metric reference support (VREFHI/VREFLO).

On-chip analog integration comprises two analog comparators with internal 10-bit references, directly routable to PWM outputs for hardware-based protection. The device uses a single 3.3-V supply with integrated voltage regulation and supports JTAG debugging via dedicated pins (TCK/TMS/TDI/TDO) multiplexed with GPIO functions.

FAQ

What is the maximum operating frequency of the TMS320F280200DAS?

The TMS320F280200DAS operates at a maximum CPU frequency of 40 MHz, corresponding to a 25-ns instruction cycle time. This speed is factory-configured and fixed for this variant; it does not support dynamic frequency scaling or overclocking. All timing-critical peripherals - including ePWM, ADC, and CPU timers - are synchronized to this clock domain, ensuring deterministic real-time behavior in motor and power control applications.

Does the TMS320F280200DAS include hardware-based security features?

Yes, the TMS320F280200DAS integrates a code-security module with a 128-bit encryption key and lock mechanism that protects on-chip Flash, SARAM, and OTP memory blocks from unauthorized read access. This prevents firmware reverse engineering and ensures intellectual property protection. Security activation is performed during programming and is irreversible - once locked, memory contents cannot be read out via JTAG or boot ROM interfaces.

How many analog-to-digital converter (ADC) channels does the TMS320F280200DAS support?

The TMS320F280200DAS supports 7 single-ended analog input channels (ADCINA0–ADCINA6) in Group A. It does not include Group B ADC inputs (ADCINBx), which are only available on 48-pin LQFP variants. The ADC is 12-bit with a 500-ns conversion time, dual sample-and-hold capability, and supports ratio-metric referencing using VREFHI/VREFLO pins for improved accuracy under supply variation.

Can the TMS320F280200DAS generate high-resolution PWM signals?

Yes, the TMS320F280200DAS supports high-resolution PWM (HRPWM) on 4 of its 8 ePWM channels (ePWM1A, ePWM2A, ePWM3A, ePWM4A). HRPWM enables sub-nanosecond duty-cycle resolution through digital dithering, allowing fine-grained control of switching timing for reduced acoustic noise and improved efficiency in high-frequency power converters and motor drives.

What is the temperature grade and package type of the TMS320F280200DAS?

The TMS320F280200DAS is specified for operation from –40°C to 125°C (S-grade) and is packaged in a 38-pin DA Thin Shrink Small-Outline Package (TSSOP) with dimensions 12.5 mm × 6.2 mm and 0.65-mm lead pitch. This package is pin-compatible with other F2802x DA variants and supports standard reflow soldering profiles per JEDEC J-STD-020.
