Hi Lina,

The suffix P stands for Performance and the E for Efficiency. The difference between the two cores is that the Efficiency cores are power consumption optimized. Tricore 1.6E has less pipeline stages (4 stages at E- and 6 stages at P-core) and is operating at a lower frequency (200 MHz for E- instead of 300 MHz for P-core). In addition the Tricore 1.6E is a single issue architecture. Please see details in the Tricore Architectural Manual and the User Manual.

Best regards,
Mr. AURIX™
