TMS320C28344ZFET

Digital Signal Processor Dsp Overview

The TMS320C28344ZFET is a Delfino microcontroller from Texas Instruments, operating at 300 MHz with a 3.33-ns instruction cycle. It features a 32-bit C28x CPU core equipped with an IEEE 754 single-precision floating-point unit (FPU). The device provides up to 130K x 16 bits of Single-Access RAM (SARAM) and an 8K x 16 Boot ROM. Key peripherals include nine ePWM channels with High-Resolution PWM (HRPWM), six eCAP modules, three QEP modules, two CAN interfaces, and three SCI modules. It utilizes a 256-ball Plastic Ball Grid Array (BGA) package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'T' indicates operation within the -40°C to 105°C temperature range. Confirm the ZFE designation corresponds to the 256-ball BGA package. Ensure compatibility with standard JTAG debugging tools as TRST requires external pull-down protection during normal operation.

Digital Signal Processor Dsp Selection Notes

Select this model when 300 MHz processing speed is required alongside extensive analog-free control peripherals. Compare against the C28342 or C28343 if lower memory capacity or different pin counts are acceptable. Verify that the absence of on-chip Flash does not conflict with system boot requirements, relying instead on external memory via XINTF.

Digital Signal Processor Dsp Part Context

The TMS320C28344 belongs to the C2834x Delfino family, which removes on-chip Flash and ADCs found in the earlier F2833x series to maximize clock speeds. It maintains code compatibility with previous C28x-based microcontrollers while offering enhanced real-time control capabilities through its high-speed architecture and dedicated motor control peripherals.

Digital Signal Processor Dsp Replacement Considerations

Direct functional replacements within the same package include the TMS320C28346ZFE and TMS320C28345ZFE, which share identical pinouts but differ in maximum clock frequency and memory size.
