Application Scenarios & Design Considerations

66MHz; V(ddh): -0.3 to +4V; communication controller

Alternative Part Number

  • MPC850CZT66 --: Same PowerQUICC MPC850 family core with 66 MHz operation; NXP is the successor of Freescale and this is a direct functional equivalent in a different naming series.
  • MPC860CZT66 --: PowerQUICC MPC860 series with 66 MHz clock, pin/functionally compatible with the MPC850 class and widely used as a drop-in upgrade.
  • MPC855TCZQ66 --: PowerQUICC MPC855T at 66 MHz offers similar integrated communications features and can serve as a functional substitute where the MPC850 is unavailable.
  • MPC855TCZT66 --: PowerQUICC MPC855T offers a similar PowerPC 8xx core and CPM at 66 MHz, providing a viable alternative with comparable integration and pin family compatibility.
