TMS320C28345ZFET

Digital Signal Processor Dsp Overview

The TMS320C28345ZFET is a high-performance floating-point microcontroller from the Delfino family, operating at 200 MHz with a 5-ns instruction cycle. It features a 32-bit C28x CPU with an IEEE 754 single-precision Floating-Point Unit (FPU). The device includes up to 258K × 16 bits of single-access RAM and an 8K × 16 Boot ROM. Key peripherals include eighteen enhanced PWM outputs with High-Resolution PWM capabilities, six capture modules, three quadrature encoder pulse modules, and extensive serial communication interfaces such as CAN, SCI, SPI, and I2C.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix ZFET against the official datasheet for package and temperature grade confirmation. The ZFE designation indicates a 256-ball Plastic Ball Grid Array package. Confirm that the 'T' suffix corresponds to the –40°C to 105°C operating range. Ensure compatibility with development tools supporting the C28x architecture.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C28345 over the C28346 or C28344 if a 200-MHz clock speed is sufficient, as it offers lower power consumption while maintaining full peripheral functionality. Compare memory requirements against the 258K SARAM limit. Ensure the 256-ball BGA package fits the board layout constraints compared to the 179-ball alternative.

Digital Signal Processor Dsp Part Context

The TMS320C28345 belongs to the C2834x Delfino series, which removes on-chip Flash and integrated ADCs found in previous generations to achieve higher clock speeds. It is code-compatible with all C28x microcontrollers. This model sits between the 300-MHz C28344/C28346 and the lower-memory variants like the C28341/C28343 in terms of performance and resource allocation.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C28346ZFE and TMS320C28344ZFE are pin-compatible alternatives offering 300-MHz operation. For lower memory needs, the TMS320C28343ZFE provides similar features with reduced SARAM. Verify that any replacement maintains the required 200-MHz or higher frequency and peripheral count.
