TMS320C28343ZFET

Digital Signal Processor Dsp Overview

The TMS320C28343ZFET is a high-performance microcontroller from the Delfino family, featuring a 32-bit C28x CPU operating at 200 MHz with a 5-ns instruction cycle. It integrates an IEEE 754 single-precision Floating-Point Unit (FPU) and up to 130KB of single-access RAM (SARAM). The device includes nine enhanced PWM outputs with High-Resolution PWM capabilities, six capture modules, three quadrature encoder pulse modules, and extensive serial communication interfaces including CAN, SCI, SPI, and I2C. It utilizes a 256-ball Plastic Ball Grid Array (BGA) package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'ZFE' corresponds to the 256-ball Plastic Ball Grid Array package and 'T' indicates the –40°C to 105°C temperature range. Confirm that the datasheet revision matches current production data, as older revisions may lack updates regarding automotive Q1 variants or timing adjustments found in later document versions.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C28343 over higher-memory variants like the C28346 if the application requires 200 MHz performance with 130KB RAM rather than 300 MHz speeds or larger memory capacities. Ensure the design accommodates the 1.1-V/1.2-V core voltage and 3.3-V I/O requirements. Verify that the 256-ball BGA footprint fits the PCB layout constraints compared to the smaller 179-ball ZHH option.

Digital Signal Processor Dsp Part Context

The TMS320C28343 belongs to the C2834x Delfino generation, which removes on-chip Flash and integrated ADCs to maximize clock speeds up to 300 MHz. It is code-compatible with previous C28x microcontrollers. This model sits between the 300 MHz C28344/C28346 and lower-speed variants, providing a balance of processing power and memory for real-time control applications.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C28343-Q1 serves as the automotive-qualified equivalent within the same package and speed grade. Other members of the C2834x family, such as the C28341, C28342, C28344, C28345, and C28346, offer different combinations of RAM size and CPU frequency but share similar peripheral sets.
