Texas Instruments TMS320F280230PTS

Overview

TMS320F280230PTS from Texas Instruments is a 40-MHz, 32-bit C28x-core Piccolo™ microcontroller in a 48-pin LQFP package, featuring 16KB on-chip flash, 4KB SARAM, 12-bit ADC with 6 channels and 1 MSPS conversion rate, three 32-bit CPU timers, and six ePWM channels-designed for real-time motor control in cost-sensitive industrial drives and eBike controllers.

For engineers reviewing the TMS320F280230PTS datasheet, TMS320F280230PTS pinout, TMS320F280230PTS application, or TMS320F280230PTS equivalent, this device delivers deterministic low-latency control with integrated analog peripherals, single 3.3-V supply operation, no power sequencing requirement, and hardware-based code security for firmware protection in embedded motion systems.

Technical Context

The TMS320F280230PTS 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. It integrates a 12-bit ADC with dual sample-and-hold, internal voltage regulator, and on-chip oscillators-enabling self-contained operation without external clock or power management ICs.

Its peripheral set includes one SCI (UART), one SPI, one I²C, three ePWM modules (6 total outputs), one eCAP module, watchdog timer, and PIE interrupt controller-all mapped to a unified memory space with zero-wait-state access to SARAM and boot ROM. The device supports real-time JTAG debugging with hardware breakpoints and live register/memory modification during execution.

FAQ

What is the maximum operating frequency of the TMS320F280230PTS?

The TMS320F280230PTS operates at a maximum CPU frequency of 40 MHz, delivering a 25-ns instruction cycle time. This speed is factory-configured and supported across its full industrial temperature range (–40°C to 105°C). The device uses an internal PLL to derive SYSCLKOUT from either an external clock or its internal zero-pin oscillator, and dynamic PLL ratio changes are supported in firmware without reset.

Does the TMS320F280230PTS include an analog-to-digital converter (ADC)?

Yes, the TMS320F280230PTS integrates a 12-bit analog-to-digital converter with 6 input channels, 1 MSPS sampling rate, and 1000 ns conversion time. It supports ratio-metric referencing using VREFHI/VREFLO, includes dual sample-and-hold circuitry, and allows hardware-triggered conversions from ePWM, CPU timers, or GPIO-enabling precise synchronization in motor control loops.

What memory resources are available on the TMS320F280230PTS?

The TMS320F280230PTS provides 16KB of on-chip flash memory (organized in four 4KB sectors), 4KB of SARAM (split across M0, M1, and L0 blocks), 8KB of boot ROM, and 1KB of OTP memory. All memory blocks are accessible in both program and data space, with zero-wait-state access to SARAM and boot ROM, and configurable wait-states for flash to optimize performance at lower clock speeds.

Is the TMS320F280230PTS pin-compatible with other F2802x0 devices?

The TMS320F280230PTS in the PT (48-pin LQFP) package shares identical pinout with TMS320F280220PTS, TMS320F280260PTS, and TMS320F280270PTS-enabling hardware reuse across performance tiers. However, functional differences exist: only the 280270 variant includes two analog comparators, and eCAP is present on all 48-pin variants except the 280220. Peripheral pin multiplexing is consistent across the family.

What debug interfaces does the TMS320F280230PTS support?

The TMS320F280230PTS supports IEEE 1149.1 JTAG for boundary-scan–capable emulation, with real-time analysis features including hardware breakpoints, data/address watchpoints, and live memory/register modification while the CPU executes code. It does not support boundary scan IDCODE by default-access requires specific JTAG state sequencing-but BYPASS and TRST functions are fully implemented for standard debug tool compatibility.
