F280034SPZ

Microcontrollers Overview

The Texas Instruments F280034SPZ is a TMS320F28003x real-time microcontroller featuring a C28x core operating at 120 MHz. It includes an IEEE 754 Floating-Point Unit (FPU), Trigonometric Math Unit (TMU), and VCRC engine. The device provides 128 KB of ECC-protected flash memory and 69 KB of RAM. It integrates three 12-bit ADCs, sixteen ePWM channels with high-resolution capability, and multiple communication interfaces including CAN FD, SPI, I2C, and UART.

Microcontrollers Feature Summary

• Integrated C28x DSP core with FPU, TMU, and VCRC for accelerated signal processing
• Configurable Logic Block (CLB) allows custom logic implementation
• High-performance analog subsystem with 12-bit ADCs and CMPSS modules
• Advanced security features including JTAGLOCK and dual-zone security

Microcontrollers Applications

• AC inverter and variable frequency drive control
• Single and multi-axis servo drives
• Industrial power supplies and DC/DC converters
• Hybrid and electric vehicle powertrain systems

Microcontrollers Procurement Notes

Verify the specific package variant against the datasheet, as the SPZ suffix indicates a 100-pin LQFP package. Confirm functional safety documentation availability if ISO 26262 compliance is required for your application design. Ensure compatibility with the intended development tools such as C2000Ware.

Microcontrollers Selection Notes

Select this model when 128 KB of flash is sufficient for the application code. It lacks the Control Law Accelerator (CLA) found in higher-end variants like the F280037 or F280039. Choose this part for cost-sensitive designs requiring high-speed PWM and analog capabilities without parallel processing needs.

Microcontrollers Part Context

This component belongs to the C2000™ real-time MCU family designed for power electronics. It shares the same core architecture and peripheral set as other F28003x devices but differs in memory size and the presence of the CLA accelerator. It targets applications requiring low latency and high switching frequencies.

Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the same series include the F280033 and F280034-Q1. Higher memory variants like the F280037 require software adaptation due to different memory maps and additional peripherals.
