Microcontrollers Procurement Notes

Verify that the specific suffix 'FGE' corresponds to the 128-pin LQFP package and commercial temperature range as defined in the official datasheet. Confirm RoHS compliance status and ensure the source document matches the Rev. 6 specification sheet. Check for any specific ordering restrictions or lifecycle notices associated with this part number from NXP or Freescale Semiconductor.

Microcontrollers Selection Notes

Select this controller when a solution requires both digital signal processing capabilities and general-purpose control functions within a compact footprint. The 56800E core offers efficient C compiler support and hardware loops suitable for complex algorithms. Consider the available GPIO count and peripheral set against application requirements for serial communication and timer functions.

Microcontrollers Part Context

This component belongs to the 56800E family of 16-bit Digital Signal Controllers originally developed by Freescale Semiconductor. The family is designed to bridge the gap between traditional DSPs and microcontrollers, offering code compatibility with earlier 56000 series cores while providing enhanced performance and integrated peripherals for embedded control applications.

Microcontrollers Replacement Considerations

Consult the official datasheet errata and cross-reference tables for compatible alternatives within the 568xx series. Verify pinout compatibility and software register mapping before substituting with other members of the 56800E family or newer generations.
