Texas Instruments TMS320F280200DAT

Overview

TMS320F280200DAT from Texas Instruments is a 32-bit C28x-core microcontroller optimized for real-time motor control and digital power applications, operating at 40 MHz (25-ns cycle time), featuring 8 kB flash, 3 kB SARAM, 3-channel 12-bit ADC (2 MSPS), 8 ePWM channels with HRPWM support, and integrated comparators. It targets compact inverter power stages and BLDC motor drives requiring deterministic timing and analog integration.

For engineers reviewing the TMS320F280200DAT datasheet, TMS320F280200DAT pinout, TMS320F280200DAT application, or TMS320F280200DAT equivalent, key selection criteria include its 38-pin TSSOP package, 40-MHz CPU speed, on-chip VREG enabling single 3.3-V supply operation, HRPWM dual-edge modulation capability, and GPIO multiplexing for ePWM/ECAP/SCI/SPI/I²C peripherals.

Technical Context

The TMS320F280200DAT implements the C28x CPU core with Harvard bus architecture, atomic instructions, and unified memory model-enabling efficient C/C++ execution in closed-loop control. Its peripheral set includes three 32-bit CPU timers, PIE interrupt controller, and dedicated ePWM modules with independent 16-bit timers and high-resolution extensions for precise gate drive timing.

It integrates analog subsystems including dual comparators with internal 10-bit references, ratio-metric ADC (0–3.3 V full-scale, VREFHI/VREFLO referenced), and on-chip temperature sensor-designed to reduce external component count in motor phase current sensing and overtemperature protection circuits.

FAQ

What is the maximum operating frequency of the TMS320F280200DAT?

The TMS320F280200DAT operates at a maximum CPU frequency of 40 MHz, corresponding to a 25-ns instruction cycle time. This speed is fixed for this variant and confirmed in TI's SPRS523P device comparison table. The internal PLL and clock control registers do not support overclocking beyond this rating. All timing-critical peripherals-including ePWM, ADC, and CPU timers-are specified and validated at this 40-MHz rate.

Does the TMS320F280200DAT include an integrated voltage regulator?

Yes, the TMS320F280200DAT includes an on-chip voltage regulator (VREG) that generates the 1.8-V core supply from a single 3.3-V input. This eliminates external LDOs and simplifies power design. The VREGENZ pin (pin 4) must be pulled high to enable regulation. When enabled, the device requires only one 3.3-V rail-no power sequencing is needed between VDD, VDDIO, or VDDA.

How many ADC channels does the TMS320F280200DAT support?

The TMS320F280200DAT supports 7 single-ended analog inputs for Group A ADC (ADCINA0–ADCINA6), as verified in the device comparison table and pinout documentation. It does not include Group B ADC channels. Conversion rate is 2 MSPS with 500-ns conversion time, and full-scale range is 0–3.3 V with ratio-metric reference support via VREFHI/VREFLO pins.

Is the TMS320F280200DAT pin-compatible with other F2802x devices in the DA package?

Yes, the TMS320F280200DAT shares identical pinout and package (38-pin DA TSSOP) with all other F2802x DA variants-including TMS320F28027DA, TMS320F28026DA, and TMS320F28023DA-as confirmed in TI's mechanical packaging data and Figure 7-2. Signal assignments, power pin locations, and JTAG interface are fully consistent across the DA family, enabling hardware reuse across speed/memory variants.

What serial communication interfaces are available on the TMS320F280200DAT?

The TMS320F280200DAT integrates one SPI module, one I²C module, and one SCI (UART-compatible) module-each with 4-level FIFOs. These are accessible via multiplexed GPIO pins (e.g., GPIO18/SPICLKA, GPIO32/SDAA, GPIO12/SCITXDA). No CAN or USB interfaces are present. All three interfaces operate at full CPU speed and support standard protocols for connecting to gate drivers, sensors, or host controllers.
