Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28032PAG | 64-pin TQFP package, identical core/peripherals but 33 GPIO and 14 ADC channels instead of 45/14. | Reduced I/O count limits use in designs requiring >33 signals (e.g., multi-sensor OBCs with isolated current sensing). | Select when board space constraints favor 10 mm × 10 mm footprint and I/O count suffices. |
| TMS320F28033PNQ | Adds CLA accelerator and increases Flash to 64 KB and SARAM to 10 KB; otherwise pin-compatible. | CLA offloads PID loops from C28x CPU - beneficial in high-bandwidth servo drives where CPU utilization exceeds 85%. | Choose when closed-loop bandwidth >20 kHz demands parallel processing beyond C28x capability. |
Compared with TMS320F28032PNQ, the TMS320F28032PAG offers smaller footprint but fewer GPIOs, while the TMS320F28033PNQ adds CLA acceleration and larger memory - both require no PCB redesign but differ in computational headroom and I/O scalability.

FAQ
What is the maximum operating frequency of the TMS320F28032PNQ?
The TMS320F28032PNQ operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67 ns instruction cycle time. This timing is achieved using the on-chip PLL with either internal zero-pin oscillators or an external crystal connected to X1/X2 pins, and is validated across the full -40°C to +125°C temperature range for automotive use.
Does the TMS320F28032PNQ include a Control Law Accelerator (CLA)?
No, the TMS320F28032PNQ does not include a CLA. According to the official device comparison table, CLA is present only in TMS320F28033 and TMS320F28035 variants. The TMS320F28032PNQ relies solely on the C28x CPU for control law execution, making it suitable for applications where loop bandwidth requirements fall within the 60-MHz CPU's deterministic processing capability.
What are the key differences between TMS320F28032PNQ and TMS320F28032PAG?
The TMS320F28032PNQ uses an 80-pin LQFP package with 45 GPIOs and 14 ADC channels, while the TMS320F28032PAG uses a 64-pin TQFP package with 33 GPIOs and the same 14 ADC channels. Both share identical CPU, Flash (32 KB), SARAM (10 KB), peripherals, and AEC Q100 qualification - differing only in package size, pin count, and I/O availability.
Which serial communication interfaces are supported by the TMS320F28032PNQ?
The TMS320F28032PNQ integrates one SCI (UART-compatible), two SPI modules, one I²C module, one LIN module, and one eCAN module. These interfaces operate independently via dedicated FIFOs (4-level for SCI/SPI/I²C) and support concurrent communication - for example, CAN for vehicle bus, LIN for auxiliary sensors, and SPI for isolated gate drivers in EV charging systems.
Is the TMS320F28032PNQ pin-compatible with other F2803x family members in the same package?
Yes, the TMS320F28032PNQ is pin-compatible with all other F2803x devices offered in the 80-pin PN LQFP package, including TMS320F28030PN, TMS320F28031PN, TMS320F28033PN, TMS320F28034PN, and TMS320F28035PN. Pin assignments, power domains, and peripheral mappings are identical - enabling hardware reuse across performance tiers via firmware update.
