Texas Instruments TMS320F280230PTT

Overview

TMS320F280230PTT from Texas Instruments is a 40-MHz C28x-core Piccolo™ microcontroller in 48-pin LQFP packaging, featuring 16KB on-chip flash, 4KB SARAM, 6-channel 12-bit ADC (1 MSPS), three 32-bit CPU timers, and six ePWM channels. It integrates code security, boot ROM, internal oscillators, and supports SCI/SPI/I²C for motor control and power conversion systems requiring deterministic real-time response.

For engineers reviewing the TMS320F280230PTT datasheet, TMS320F280230PTT pinout, TMS320F280230PTT application, or TMS320F280230PTT equivalent, this page delivers verified specifications, validated package mapping, confirmed peripheral capabilities, and real-world use context for embedded control design, BOM validation, and migration planning.

Technical Context

The TMS320F280230PTT implements the TMS320C28x 32-bit fixed-point CPU with Harvard bus architecture, 25-ns instruction cycle time, and unified memory programming model. It executes C/C++ efficiently with atomic operations, fast interrupt response, and 8-level protected pipeline-enabling single-processor handling of both control algorithms and system management.

Its analog subsystem includes a 12-bit ADC with 6 input channels, 1000-ns conversion time, ratio-metric VREFHI/VREFLO support, and dual sample-and-hold; no external analog support pins are required. The device uses an integrated voltage regulator for single 3.3-V rail operation and features POR/BOR, two zero-pin oscillators, and dynamic PLL ratio changes.

FAQ

What is the maximum operating frequency of the TMS320F280230PTT?

The TMS320F280230PTT operates at a maximum CPU clock frequency of 40 MHz, corresponding to a 25-ns instruction cycle time. This is fixed by its internal PLL configuration and silicon characterization; overclocking is not supported. All timing-critical peripherals-including ePWM, ADC, and timers-are synchronized to this SYSCLKOUT signal, ensuring deterministic behavior in real-time control loops. The TMS320F280230PTT does not support dynamic frequency scaling beyond factory-trimmed PLL settings.

Does the TMS320F280230PTT include an analog comparator?

No, the TMS320F280230PTT does not include an analog comparator block. According to TI's SPRS810B datasheet Table 2-1, comparators are only present in the TMS320F280270 (2 comparators) and TMS320F280260 (1 comparator) variants. The TMS320F280230PTT shares the same peripheral set as the TMS320F280220PTT, which explicitly omits comparators. Designers requiring comparator functionality must select TMS320F280270PTT or add external comparators.

What memory resources are available on the TMS320F280230PTT?

The TMS320F280230PTT includes 16K × 16-bit flash (organized in four 4K sectors), 4K × 16-bit SARAM (M0/M1), 2K × 16-bit L0 SARAM, 8K × 16-bit boot ROM, and 1K × 16-bit OTP. Flash and SARAM are dual-mapped for code/data use; OTP stores calibration data or security keys. The memory map (Figure 2-1) confirms no RAM is reserved for stack-only use-the linker assigns M1 as default stack location, but both M0 and M1 are fully programmable for code or variables.

Can the TMS320F280230PTT operate from a single 3.3-V supply?

Yes, the TMS320F280230PTT is designed for single 3.3-V operation with no power sequencing requirement. Its integrated voltage regulator generates internal analog and digital rails from VDD; VDDA and VDDIO are internally derived and do not require separate external supplies. TI specifies that VDD, VDDA, and VDDIO may be tied together to one clean 3.3-V source, simplifying power design. Brown-out reset (BOR) and power-on reset (POR) are built-in and active across the full temperature range.

Which communication interfaces are supported by the TMS320F280230PTT?

The TMS320F280230PTT supports SCI (asynchronous UART), SPI (master/slave), and I²C (master/slave) interfaces-all implemented in hardware with dedicated FIFOs (4-level depth each). These peripherals are accessible via multiplexed GPIO pins (e.g., GPIO28/29 for SCI, GPIO16–19 for SPI, GPIO32/33 for I²C) and managed through the PIE interrupt controller. No USB, CAN, or Ethernet interfaces are integrated; those require external transceivers or companion ICs.
