Texas Instruments TMS320F28030RSHT

Overview

TMS320F28030RSHT from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated analog peripherals, designed for closed-loop motor and power control in compact industrial inverters and DC/DC converters. It features 16 kB flash, 6 kB SARAM, 3× 32-bit CPU timers, 14 ePWM channels, 16-channel 12-bit ADC (2 MSPS), and on-chip temperature sensor - all in a 56-pin VQFN package rated for –40°C to 125°C operation.

For engineers reviewing the TMS320F28030RSHT datasheet, TMS320F28030RSHT pinout, TMS320F28030RSHT application, or TMS320F28030RSHT equivalent, key selection criteria include its 56-pin RSH VQFN footprint, absence of CLA accelerator, fixed 16 kB flash size, and support for eCAN, LIN, SPI, I²C, and UART interfaces in high-density power conversion designs.

Technical Context

The TMS320F28030RSHT implements a Harvard-architecture C28x CPU executing at 60 MHz (16.67 ns cycle time) with atomic instructions, fast interrupt response, and unified memory model. Its peripheral set centers on real-time actuation: ePWM modules with dead-band and trip-zone protection, 12-bit ADC with dual sample-and-hold and 500 ns conversion time, and three independent comparators with internal 10-bit references routed directly to PWM outputs.

System-level integration includes single 3.3-V supply operation with internal voltage regulator, JTAG boundary scan (IEEE 1149.1), programmable GPIO filtering, and PIE interrupt expansion supporting all peripherals. No CLA accelerator is present - distinguishing it from F28033/F28035 variants - and boot ROM (8K × 16) enables secure firmware initialization without external memory.

FAQ

What is the maximum operating temperature rating for the TMS320F28030RSHT?

The TMS320F28030RSHT is rated for operation from –40°C to 125°C ambient temperature (S-grade), making it suitable for under-hood automotive power modules and high-temperature industrial enclosures where thermal derating is critical. This rating is validated per TI's characterization data and applies to the full 56-pin RSH VQFN package configuration.

Does the TMS320F28030RSHT include a Control Law Accelerator (CLA)?

No, the TMS320F28030RSHT does not include a CLA. Per TI's device comparison table (SPRS584Q), CLA is only present in TMS320F28033 and TMS320F28035 variants. The TMS320F28030RSHT relies solely on its 60-MHz C28x CPU for control law execution, with hardware-accelerated peripherals like ePWM and ADC offloading timing-critical tasks.

How many ePWM modules are available on the TMS320F28030RSHT?

The TMS320F28030RSHT provides 14 ePWM channels, as confirmed in Table 4-1 of the SPRS584Q datasheet. These are distributed across seven ePWM modules (EPWM1–EPWM7), each offering A/B channel pairs, dead-band generation, trip-zone inputs, and synchronization capabilities - sufficient for three-phase inverter, PFC, and auxiliary converter control in a single chip.

What ADC performance specifications apply to the TMS320F28030RSHT?

The TMS320F28030RSHT features a 12-bit successive-approximation ADC with 2 MSPS throughput and 500 ns conversion time. It supports 16 input channels (ADCINA0–7, ADCINB0–7), dual sample-and-hold, and ratio-metric operation using VREFHI/VREFLO - enabling accurate current sensing and voltage monitoring in noisy power converter environments.

Is the TMS320F28030RSHT pin-compatible with other F2803x devices in the RSH package?

Yes, all F2803x devices in the 56-pin RSH VQFN package - including TMS320F28030RSHT, TMS320F28031RSHT, TMS320F28032RSHT, TMS320F28033RSHT, and TMS320F28034RSHT - share identical pinouts and mechanical footprint. Functional differences (e.g., flash size, peripheral count) do not affect physical layout, enabling drop-in replacement during design iteration or qualification.
