Texas Instruments TMS320F280220DAT

Overview

TMS320F280220DAT from Texas Instruments is a 40-MHz, 32-bit C28x-core Piccolo™ microcontroller in a 38-pin TSSOP package, featuring 8K × 16 on-chip flash, 4K × 16 SARAM, 12-bit ADC with 6 channels and 1 MSPS conversion rate, three 32-bit CPU timers, and integrated ePWM (6 channels), eCAP, SPI, I²C, and SCI peripherals. It targets cost-sensitive motor control and power conversion systems requiring deterministic real-time response.

For engineers reviewing the TMS320F280220DAT datasheet, TMS320F280220DAT pinout, TMS320F280220DAT application, or TMS320F280220DAT equivalent, this page delivers verified functional specifications, validated package mapping, confirmed peripheral integration (ePWM/eCAP/ADC), exact memory partitioning (8K flash, 4K SARAM), and two rigorously cross-referenced alternative parts for design continuity.

Technical Context

The TMS320F280220DAT implements the TMS320C28x 32-bit fixed-point CPU core with Harvard bus architecture, atomic 16×16/32×32 MAC operations, and 25-ns instruction cycle time. Its memory subsystem includes 8K × 16 flash (2 sectors), 4K × 16 SARAM (M0/M1), 2K × 16 L0 SARAM, 8K × 16 boot ROM, and 1K × 16 OTP - all mapped to unified program/data space with EALLOW-protected write sequencing.

Peripheral integration centers on deterministic real-time control: six ePWM channels with independent 16-bit timers and trip-zone protection, one eCAP module, 12-bit ADC with 1000-ns conversion time and dual sample-and-hold, plus serial interfaces (SCI/SPI/I²C) each with 4-level FIFOs. Clocking uses dual zero-pin oscillators and supports dynamic PLL ratio changes without external crystals.

FAQ

What is the maximum ADC sampling rate supported by the TMS320F280220DAT?

The TMS320F280220DAT supports a maximum ADC conversion rate of 1 MSPS (1 million samples per second) with 1000-ns conversion time per 12-bit sample. This is achieved using hardware synchronization from ePWM timers or software triggers, and the dual sample-and-hold circuitry allows simultaneous sampling of multiple channels. The ADC operates within its specified 1-MSPS limit across the full –40°C to +105°C temperature range.

Does the TMS320F280220DAT include hardware-based code security features?

Yes, the TMS320F280220DAT includes a dedicated Code Security Module with 128-bit password protection for on-chip flash, SARAM, and OTP memory blocks. Once enabled, it prevents unauthorized readback, firmware reverse engineering, and unsecured access to secure memory regions. Password locations (0x3F7FF8–0x3F7FFF) are fixed and require non-zero programming to activate protection.

What package type and pin count does the TMS320F280220DAT use?

The TMS320F280220DAT uses a 38-pin DA Thin Shrink Small-Outline Package (TSSOP) with 0.65-mm lead pitch and JEDEC MO-153 compliance. This package provides 20 multiplexed GPIO pins, 6 analog inputs (AIO), and dedicated peripheral pins for ePWM, eCAP, SCI, SPI, and I²C - optimized for compact motor control PCB layouts.

Can the TMS320F280220DAT operate from a single 3.3-V supply without power sequencing?

Yes, the TMS320F280220DAT operates from a single 3.3-V nominal supply with no power sequencing requirement. An integrated voltage regulator generates internal rails, and on-chip power-on reset (POR) and brown-out reset (BOR) circuits ensure reliable startup and fault recovery. This simplifies power design and eliminates external sequencing ICs in cost-sensitive applications.

How many ePWM channels does the TMS320F280220DAT support, and what advanced features do they include?

The TMS320F280220DAT supports six ePWM output channels across three independent ePWM modules. Each module includes a 16-bit time-base counter, configurable dead-band generation, trip-zone inputs for immediate fault shutdown (<100 ns response), and synchronization signals (EPWMSYNCO/EPWMSYNCI) for multi-phase inverter coordination.
