Product details
Overview
TMS320F280230DAT from Texas Instruments is a 40-MHz C28x-core Piccolo™ microcontroller in a 38-pin TSSOP package, featuring 16KB flash, 4KB SARAM, 12-bit 6-channel ADC (1 MSPS), three 32-bit CPU timers, and six ePWM channels for real-time motor control in compact industrial drives.
For engineers reviewing the TMS320F280230DAT datasheet, TMS320F280230DAT pinout, TMS320F280230DAT application, or TMS320F280230DAT equivalent, this device delivers deterministic real-time control with integrated analog peripherals, single 3.3-V supply operation, on-chip oscillators, and code-security support - critical for cost-sensitive embedded power conversion systems.
Technical Context
The TMS320F280230DAT implements the TMS320C28x 32-bit fixed-point CPU core with Harvard bus architecture, atomic operations, and 25-ns instruction cycle time. It integrates a peripheral bus with PIE interrupt expansion supporting all on-chip peripherals including ePWM, eCAP, SCI, SPI, and I²C.
Its analog subsystem includes a 12-bit ADC with 1-MSPS sampling rate, dual sample-and-hold, ratio-metric reference support (VREFHI/VREFLO), and direct routing to ePWM trip zones. The device uses an internal voltage regulator for single-rail 3.3-V operation and includes POR/BOR, two zero-pin oscillators, and no external power sequencing requirement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280220PT | Same 40-MHz C28x core, 8KB flash, 3KB SARAM, identical peripheral set except no eCAP module | Limited to simpler timing-critical tasks without capture-based position sensing (e.g., basic speed control only) | Select when flash budget <16KB suffices and eCAP functionality is unnecessary |
| TMS320F280270DAT | 50-MHz C28x core, 16KB flash, same 38-pin DA package, adds second comparator and eCAP module | Enables higher PWM resolution, faster control loops, and hardware-based zero-crossing detection for PFC or resolver interfaces | Select when >40-MHz performance, extra analog compare capability, or edge-triggered capture is required |
Compared with TMS320F280220PT, the TMS320F280230DAT provides double the SARAM and adds eCAP for position feedback - critical for servo-grade motion control; versus TMS320F280270DAT, it trades 10-MHz CPU headroom and one comparator for lower cost and identical footprint in thermally constrained designs.

FAQ
What is the maximum operating frequency of the TMS320F280230DAT?
The TMS320F280230DAT operates at a maximum CPU frequency of 40 MHz, delivering a 25-ns instruction cycle time. This speed is fixed by the device variant and supported across its full temperature range (–40°C to 105°C). The TMS320F280230DAT does not support dynamic PLL ratio changes beyond its factory-configured 40-MHz SYSCLKOUT; higher frequencies require the 50-MHz TMS320F280270DAT variant.
Does the TMS320F280230DAT include an analog comparator?
No, the TMS320F280230DAT does not include an analog comparator. According to the SPRS810B datasheet Table 2-1, comparators are only present in the TMS320F280270 (2 comparators) and TMS320F280260 (1 comparator) variants. The TMS320F280230DAT and TMS320F280220DAT omit this peripheral entirely - confirmed by absence in functional block diagram and peripheral listing.
What memory resources are available on the TMS320F280230DAT?
The TMS320F280230DAT includes 16K × 16-bit flash (four 4K sectors), 4K × 16-bit SARAM (split across M0, M1, and L0 blocks), 1K × 16-bit OTP, and 8K × 16-bit boot ROM. All memory is mapped to both program and data spaces, enabling flexible use for code, constants, and variables - with 0-wait-state access for SARAM and boot ROM, and configurable wait-states for flash.
Which communication interfaces are integrated into the TMS320F280230DAT?
The TMS320F280230DAT integrates one SCI (UART), one SPI, and one I²C module - each with 4-level FIFOs. These are accessible via multiplexed GPIO pins (e.g., GPIO28/29 for SCI, GPIO16–19 for SPI, GPIO32/33 for I²C). No CAN, USB, or Ethernet interfaces are included; those require external transceivers or companion ICs.
Is the TMS320F280230DAT pin-compatible with other F2802x0 devices in the same package?
Yes, the TMS320F280230DAT is pin-compatible with the TMS320F280220DAT, TMS320F280270DAT, and TMS320F280260DAT in the 38-pin DA TSSOP package. Pin assignments, electrical characteristics, and thermal behavior are identical across these variants - enabling drop-in replacement where firmware and peripheral usage align with the target device's feature set.
