TMS320C28345ZFEQ

Digital Signal Processor Dsp Overview

The TMS320C28345ZFEQ is a single-core Delfino microcontroller from Texas Instruments, operating at 200 MHz with a 5-ns instruction cycle. It features a 32-bit TMS320C28x CPU with an IEEE 754 single-precision Floating-Point Unit (FPU). The device provides up to 258K × 16 of Single-Access RAM (SARAM) and an 8K × 16 Boot ROM. Key peripherals include nine ePWM outputs, six eCAP modules, three QEP channels, two CAN modules, and three SCI interfaces. It utilizes a 256-ball Plastic Ball Grid Array (BGA) package and supports an operating temperature range of –40°C to 125°C.

Digital Signal Processor Dsp Feature Summary

• 200-MHz TMS320C28x CPU with IEEE 754 FPU
• 258K × 16 SARAM and 8K × 16 Boot ROM
• Nine HRPWM outputs with 55-ps MEP resolution

• Uninterruptible and Server Power Supplies

Digital Signal Processor Dsp Procurement Notes

Verify the 'Q' suffix indicates AEC-Q100 qualification for automotive applications and a –40°C to 125°C temperature range. Confirm the ZFE package designation corresponds to the 256-ball BGA form factor. Ensure compatibility with existing 3.3-V I/O designs.

Digital Signal Processor Dsp Selection Notes

Select this model over the C28346 or C28344 if a 200-MHz clock speed is sufficient, as it offers the same memory capacity but lower frequency. Compare against the C28343 if fewer PWM channels are acceptable. Verify that the absence of on-chip Flash requires external memory or alternative boot strategies.

Digital Signal Processor Dsp Part Context

The TMS320C28345 belongs to the C2834x Delfino family, which removes on-chip Flash to achieve higher clock speeds compared to the original F2833x series. It is code-compatible with all C28x microcontrollers. The ZFE package variant is distinct from the 179-ball ZHH MicroStar BGA option available in the same family.

Digital Signal Processor Dsp Replacement Considerations

TMS320C28346ZFEQ: Higher performance variant running at 300 MHz with identical memory and package.
