Product Summary

The MC9S12XET512VAL is the micro controller which is a further development of the S12XD-Family including new features for enhanced system integrity and greater functionality. These new features include a Memory Protection Unit (MPU) and Error Correction Code (ECC) on the Flash memory together with enhanced EEPROM functionality (EEE), an enhanced XGATE, an Internally filtered, frequency modulated Phase Locked Loop (IPLL) and an enhanced ATD.
