TMS320C28342ZFEQ

Digital Signal Processor Dsp Overview

The TMS320C28342ZFEQ is a C28x-based Delfino microcontroller operating at 300 MHz with an integrated IEEE 754 single-precision floating-point unit. It features up to 98K x 16 SARAM and 8K x 16 Boot ROM within a 256-ball plastic BGA package. The device supports AEC Q100 qualification for automotive applications, functioning reliably between -40°C and 125°C. Key peripherals include nine ePWM channels with HRPWM capabilities, six eCAP modules, three QEP channels, dual CAN interfaces, and multiple serial communication ports.

Digital Signal Processor Dsp Feature Summary

• Automotive-grade reliability (AEC Q100) with extended temperature range (-40°C to 125°C)
• Integrated control peripherals including 9-channel ePWM with 55-ps MEP resolution
• Up to 98K x 16 SARAM and 8K x 16 Boot ROM

Digital Signal Processor Dsp Applications

• Industrial AC Inverter Drives
• Industrial Servo Amplifiers and Controllers
• Computer Numerical Control (CNC) Machining
• Solar Inverters

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'Q' indicates AEC Q100 automotive qualification and the 125°C operating limit during sourcing. Confirm the ZFE package designation matches the required 256-ball BGA footprint. Ensure the component meets RoHS compliance standards as specified in the manufacturer's documentation.

Digital Signal Processor Dsp Selection Notes

Select this model when high-speed real-time control requires a 300 MHz clock rate and floating-point processing. The Q-suffix variant is necessary for automotive environments requiring operation up to 125°C. Compare memory requirements against other C2834x variants; this part provides 98K SARAM, which is less than the C28346 but sufficient for many servo and drive applications.

Digital Signal Processor Dsp Part Context

This component belongs to the C2834x Delfino family, designed for demanding real-time control applications. Unlike earlier F2833x devices, it omits on-chip Flash and ADCs to maximize clock speed. It maintains code compatibility with all previous C28x microcontrollers while offering enhanced PWM and capture peripherals.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible alternatives within the same series include TMS320C28341ZFEQ (200 MHz) or TMS320C28343ZFEQ (200 MHz). Higher performance options like TMS320C28345ZFEQ or TMS320C28346ZFEQ offer increased RAM but share the same package.
