Product details
Overview
F280045PZSR from Texas Instruments is a 100MHz C28x-based real-time MCU with IEEE 754 FPU, CLA accelerator, 256KB ECC-protected flash, 100KB RAM, and integrated analog subsystem including three 3.45MSPS 12-bit ADCs - deployed in solar string inverters and EV charging power modules for high-precision closed-loop control.
For engineers reviewing the F280045PZSR datasheet, F280045PZSR pinout, F280045PZSR application, or F280045PZSR equivalent, key selection factors include its 100-pin LQFP package, dual-zone security, ASIL B functional safety qualification, and support for InstaSPIN-FOC™ sensorless motor control in industrial power conversion systems.
Technical Context
The F280045PZSR implements a dual-core real-time control architecture: the main C28x CPU runs at 100MHz with FPU, TMU, and VCU-I for fast trigonometric and complex math, while the independent CLA executes floating-point control loops in parallel. Its analog front end integrates seven PGAs (gain 3/6/12/24), seven windowed comparators with 12-bit DACs, and four SDFM channels for sigma-delta modulator interfacing.
System-level timing is managed via two internal 10MHz oscillators, missing-clock detection, and windowed watchdog; power sequencing uses internal 1.2V VREG or DC-DC generation from 3.3V I/O supply, enabling single-rail board design with brownout reset protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | TMS320C28x 32-bit, 100MHz - delivers deterministic real-time signal processing for motor torque and current loops. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core power supply and ground | 1.2V core domain with dedicated decoupling; requires low-ESR ceramic capacitors adjacent to pins 4–5, 70–71, 99–100. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049PZSR | Includes Configurable Logic Block (CLB) and InstaSPIN-FOC™ ROM; same 100-pin LQFP package and 256KB flash. | Required for designs needing custom logic augmentation (e.g., resolver-to-digital conversion) or pre-validated sensorless FOC. | Select F280049PZSR when CLB or InstaSPIN-FOC™ functionality is mandatory; F280045PZSR is optimal for cost-sensitive, CLB-free implementations. |
| TMS320F280041PZSR | 128KB flash, no CLA, no InstaSPIN-FOC™ ROM; identical 100-pin LQFP package and analog/peripheral set. | Suitable for simpler control tasks where full 256KB flash and CLA acceleration are unnecessary. | Choose F280041PZSR for entry-level motor drives or legacy migration where reduced memory and compute capability suffice. |
Compared with F280049PZSR, F280045PZSR removes CLB and InstaSPIN-FOC™ but retains full CLA, ADC, and ePWM capability - making it ideal for high-performance, non-sensorless applications. Against F280041PZSR, it doubles flash and adds CLA, enabling more complex control stacks and firmware redundancy.

FAQ
What is the maximum operating frequency of the F280045PZSR CPU core?
The F280045PZSR features a TMS320C28x 32-bit CPU core rated for 100MHz operation under all supported junction temperatures (–40°C to 125°C). This frequency is guaranteed with proper power supply decoupling, thermal management, and clock source stability - enabling sub-microsecond interrupt response and deterministic execution of control law routines.
Does the F280045PZSR support functional safety certification for automotive use?
The F280045PZSR is not an AEC-Q100 qualified part and does not carry ISO 26262 ASIL B certification. While it shares the same silicon as certified variants like F280049PZQR, only devices explicitly listed in TI's Functional Safety-Compliant table (SPRS945H Table 3-1) meet automotive safety requirements. For automotive applications, use F280049PZQR or F280048PZQR instead of F280045PZSR.
How many analog input channels does the F280045PZSR support via its ADC subsystem?
The F280045PZSR supports up to 21 external single-ended analog input channels across its three 12-bit ADCs when packaged in the 100-pin LQFP (PZ) variant. Additionally, seven PGA inputs provide conditioned analog paths for high-gain, low-noise signal acquisition - all synchronized and post-processed via four integrated PPB blocks per ADC.
Is the F280045PZSR pin-compatible with other TMS320F28004x family members in the same package?
Yes - the F280045PZSR is fully pin-compatible with all 100-pin PZ-package variants in the F28004x family, including F280049PZSR, F280041PZSR, and their Q1 automotive derivatives. Pin assignments, power domains, I/O voltage levels, and peripheral mappings match exactly, allowing drop-in replacement where functional requirements align.
What communication interfaces are available on the F280045PZSR for system connectivity?
The F280045PZSR provides two CAN 2.0B ports, two UART-compatible SCIs, two SPI ports, one I²C interface, one LIN interface, one PMBus interface, and one Fast Serial Interface (FSI) - all accessible on the 100-pin PZ package. These interfaces support mixed-criticality communication, including real-time motor control messaging over CAN and high-speed configuration/data transfer via FSI.
