TMS320C28342ZFET

Digital Signal Processor Dsp Overview

The TMS320C28342ZFET is a Delfino microcontroller featuring a 32-bit C28x CPU with an IEEE 754 single-precision floating-point unit (FPU). Operating at up to 300 MHz, it provides 98 KB of single-access SARAM and an 8 KB boot ROM. The device includes a six-channel DMA controller, a 16/32-bit external memory interface (XINTF), and enhanced control peripherals such as nine ePWM outputs with high-resolution PWM capabilities. It utilizes a 256-ball plastic ball grid array (BGA) package.

Digital Signal Processor Dsp Feature Summary

• 300-MHz C28x core with integrated FPU for efficient floating-point calculations
• 98 KB on-chip SARAM and 8 KB Boot ROM
• Six-channel DMA controller supporting McBSP, XINTF, and SARAM transfers
• Nine ePWM channels with High-Resolution PWM (HRPWM) support

Digital Signal Processor Dsp Applications

• Industrial AC inverter drives
• Industrial servo amplifiers and controllers
• Computer numerical control (CNC) machining
• Uninterruptible and server power supplies

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix ZFE corresponds to the 256-ball BGA package and temperature grade T (-40°C to 105°C). Confirm that the ordering information matches the exact pinout and electrical specifications required for the target design. Cross-reference the datasheet revision history for any timing or functional updates.

Digital Signal Processor Dsp Selection Notes

Select this model when a 300-MHz clock speed and 98 KB RAM are required. Compare against the C28341 if lower performance suffices, or the C28343/C28344 if additional peripheral counts like QEP channels or eCAP modules are needed. Ensure the 256-ball BGA footprint fits the PCB layout constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C2834x Delfino family, which removes on-chip Flash found in previous generations to maximize processing speed. It maintains code compatibility with existing C28x microcontrollers while offering higher performance through its optimized architecture and extensive peripheral set.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same package include the TMS320C28341ZFE (200 MHz, 98 KB RAM) and TMS320C28343ZFE (200 MHz, 130 KB RAM). Higher-performance variants like the TMS320C28344ZFE (300 MHz, 130 KB RAM) offer increased memory but require verification of peripheral differences.
