TMS320C28346ZFEQ

Digital Signal Processor Dsp Overview

The TMS320C28346ZFEQ is a single-core Delfino microcontroller from Texas Instruments, operating at up to 300 MHz. It features a 32-bit C28x CPU with an IEEE 754 single-precision Floating-Point Unit (FPU). The device provides 258K × 16 of on-chip Single-Access RAM (SARAM) and 8K × 16 Boot ROM. It lacks integrated Flash memory and ADCs, relying instead on external interfaces. Key peripherals include nine ePWM channels with High-Resolution PWM (HRPWM), six eCAP modules, three QEP modules, two CAN modules, and multiple serial communication interfaces.

Digital Signal Processor Dsp Feature Summary

• High-performance 32-bit C28x CPU running at 300 MHz with IEEE 754 FPU
• 258K × 16 SARAM and 8K × 16 Boot ROM
• Nine ePWM outputs with up to 9 HRPWM channels (55-ps MEP resolution)
• Six 32-bit eCAP modules and three 32-bit QEP modules

Digital Signal Processor Dsp Applications

Digital Signal Processor Dsp Procurement Notes

Verify the 'Q' suffix indicates AEC-Q100 qualification for automotive applications (-40°C to 125°C). Confirm the 'ZFE' package corresponds to the 256-ball Plastic Ball Grid Array. Ensure the specific revision level matches project requirements, as datasheet revisions may update timing or electrical characteristics.

Digital Signal Processor Dsp Selection Notes

Select this model when high-speed floating-point processing at 300 MHz is required without onboard Flash or ADC resources. Compare against C28345 (200 MHz) if lower power consumption is acceptable. Verify that external memory and ADC interfaces can accommodate the system's data acquisition needs, as these are not integrated on-chip.

Digital Signal Processor Dsp Part Context

The TMS320C28346 belongs to the C2834x Delfino family, which removes on-chip Flash and ADCs found in the earlier F2833x series to achieve higher clock speeds. It is code-compatible with other C28x microcontrollers. The ZFE package variant offers a 256-ball BGA footprint, distinct from the 179-ball ZHH option available for lower-memory variants.
