Product details
Overview
F280041CPZS from Texas Instruments is a 32-bit real-time microcontroller (MCU) with 100MHz C28x CPU, IEEE 754 single-precision FPU, CLA accelerator, 128KB flash, and 100KB RAM. It integrates three 3.45MSPS 12-bit ADCs, 16 ePWM channels (150ps resolution), seven PGAs, and dual CAN interfaces. It targets high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the F280041CPZS datasheet, F280041CPZS pinout, F280041CPZS application, or F280041CPZS equivalent, key selection criteria include CLA-enabled parallel processing, InstaSPIN-FOC™ ROM support, functional safety documentation for ASIL B, and 100-pin LQFP package compatibility with industrial thermal requirements (–40°C to 125°C junction).
Technical Context
The F280041CPZS implements a dual-core real-time control architecture: the main C28x CPU runs at 100MHz with TMU/VCU-I acceleration for fast trigonometric and complex math, while the independent CLA executes floating-point control loops concurrently. Its analog subsystem includes three synchronized ADCs with four post-processing blocks each and seven PGA inputs supporting gain settings of 3/6/12/24.
Control peripherals feature 16 ePWM channels with hardware dead-band and trip-zone logic, two eQEP modules, seven eCAP modules (two with HRCAP), and four SDFM input channels. Communication is supported via two CAN ports, two SPI, two SCI, one I²C, one LIN, one PMBus, and one FSI interface - all pin-bootable and highly multiplexed.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049CPZS | 256KB flash, 4 CLB tiles, full InstaSPIN-FOC™ support - adds 128KB flash and enhanced CLB resources. | Preferred for complex multi-axis servo drives requiring larger code space and advanced position management logic. | Select F280049CPZS when >128KB flash or additional CLB tiles are required; F280041CPZS remains optimal for cost-sensitive single-axis OBC or string inverter designs. |
| TMS320F280035CPMQR | 64-pin LQFP, CAN-FD support, 128KB flash, no CLB - smaller footprint, newer CAN protocol, but lacks CLA and CLB. | Better suited for space-constrained telecom rectifiers or server PSUs where CAN-FD diagnostics are prioritized over motor control acceleration. | Choose F280035CPMQR for CAN-FD–enabled systems with tight PCB area constraints; F280041CPZS retains CLA/CLB advantages for high-performance motor control. |
Compared with F280049CPZS, F280041CPZS offers identical CPU/CLA/ADC/peripheral architecture but reduced flash and CLB count - lowering BOM cost without sacrificing real-time control latency. Versus F280035CPMQR, it trades CAN-FD and pin count for CLA acceleration and analog integration - making it superior for precision power conversion where computational offload matters more than protocol extension.

FAQ
What is the maximum operating frequency of the F280041CPZS CPU core?
The F280041CPZS features a TMS320C28x 32-bit CPU core running at 100MHz. This clock speed is fixed and guaranteed across the full temperature range (–40°C to 125°C junction). The device also includes a 100MHz Control Law Accelerator (CLA) that operates independently of the main CPU, enabling parallel real-time control execution without affecting CPU throughput.
Does the F280041CPZS support InstaSPIN-FOC™ out of the box?
Yes, the F280041CPZS includes the InstaSPIN-FOC™ motor control library pre-stored in on-chip ROM. This allows immediate deployment of sensorless field-oriented control without external memory or firmware loading. The library is accessible via standard APIs and supports common BLDC and PMSM motor types used in EV charging and HVAC applications.
What package type and pin count does the F280041CPZS use?
The F280041CPZS uses a 100-pin Low-profile Quad Flatpack (LQFP) package with PZ suffix, measuring 14mm × 14mm with 0.5mm pitch. This package supports all integrated peripherals including dual CAN, FSI, 16 ePWM channels, and 40 GPIOs - making it suitable for industrial power modules requiring robust thermal performance and signal routing flexibility.
How much flash and RAM memory does the F280041CPZS have?
The F280041CPZS integrates 128KB (64KW) of ECC-protected flash memory in a single bank and 100KB (50KW) of RAM - split into dedicated and shared blocks with ECC or parity protection. This memory configuration supports secure firmware updates, real-time data logging, and complex control algorithms typical in solar inverters and EV charging systems.
Is the F280041CPZS qualified for automotive applications?
No, the F280041CPZS is not AEC-Q100 qualified. It carries the 'S' temperature grade (–40°C to 125°C junction), intended for industrial applications. For automotive use, TI offers the pin-compatible F280041C-Q1 variant (Q-grade, AEC-Q100 qualified), which shares identical architecture and peripherals but undergoes additional automotive reliability testing and screening.
