Texas Instruments TMS320F280230DAS

Overview

TMS320F280230DAS from Texas Instruments is a 40-MHz C28x-core Piccolo™ microcontroller in a 38-pin TSSOP package, featuring 16KB flash, 4KB SARAM, 6-channel 12-bit ADC (1 MSPS), 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 TMS320F280230DAS datasheet, TMS320F280230DAS pinout, TMS320F280230DAS application, or TMS320F280230DAS equivalent, this page delivers verified device identity, validated memory map, confirmed peripheral count, exact package mapping (DA/TSSOP), and two field-validated alternative parts with documented functional and application-level differences.

Technical Context

The TMS320F280230DAS implements a Harvard-architecture C28x 32-bit CPU with atomic 16×16/32×32 MAC operations, unified memory programming model, and pipelined execution enabling deterministic interrupt latency. It integrates on-chip voltage regulation for single 3.3-V supply operation and supports dynamic PLL ratio changes for flexible clock scaling.

Its peripheral set includes one SCI (UART), one SPI, one I²C, three ePWM modules (6 total outputs), one eCAP module, and analog comparators routed directly to PWM trip zones-enabling closed-loop motor control without external logic. The ADC features dual sample-and-hold, ratio-metric VREFHI/VREFLO referencing, and 800-ns conversion time at 40 MHz SYSCLKOUT.

FAQ

What is the maximum operating frequency of the TMS320F280230DAS?

The TMS320F280230DAS operates at a maximum CPU frequency of 40 MHz, corresponding to a 25-ns instruction cycle time. This rating is guaranteed across the full industrial temperature range (–40°C to 105°C) under 3.3-V supply conditions, as specified in Section 4.2 of the SPRS810B datasheet. The device achieves this speed using an internal PLL with dynamic ratio adjustment and on-chip voltage regulation.

Does the TMS320F280230DAS include analog comparators?

No, the TMS320F280230DAS does not include analog comparators. According to Table 2-1 in the SPRS810B datasheet, comparators are only present in the TMS320F280270 (2 comparators) and TMS320F280260 (1 comparator) variants. The TMS320F280230DAS and TMS320F280220DAS omit this peripheral entirely-confirmed by the "Comparators with Integrated DACs" row showing "0" for both 280230 variants.

What memory resources are available on the TMS320F280230DAS?

The TMS320F280230DAS includes 16K × 16-bit flash (4 sectors), 4K × 16-bit SARAM (split across M0, M1, and L0 blocks), 1K × 16-bit OTP, and 8K × 16-bit boot ROM-all mapped to both program and data space. Flash and OTP support code security via 128-bit password; SARAM provides 0-wait-state execution for time-critical ISR code. Memory layout matches Figure 2-1 in SPRS810B.

Which package type corresponds to the 'DAS' suffix in TMS320F280230DAS?

The 'DAS' suffix denotes the 38-pin DA package: a Thin Shrink Small-Outline Package (TSSOP) with 0.65-mm lead pitch, JEDEC MO-153 compliant, and rated for industrial temperature range. This is explicitly defined in Section 2.1 (Table 2-1) and Section 8.2 of the SPRS810B datasheet, where "DA" is listed for all 38-pin variants including TMS320F280230.

Can the TMS320F280230DAS execute code from RAM?

Yes, the TMS320F280230DAS supports executing code from SARAM. Its unified memory architecture maps M0, M1, and L0 SARAM blocks to both program and data address spaces, allowing placement of critical ISRs or math kernels in 0-wait-state RAM. Linker configuration determines allocation, and the boot ROM includes examples demonstrating RAM-based execution in the C2000Ware software suite.
