S912XEP100W1MAL

16位微控制器 - MCU 16-bit MCU, S12X core, 1MB Flash, 50MHz, -40/+125degC, Automotive Qualified, QFP 112

Introduction  S912XEP100W1MAL

The MC9S12XE-Family of micro controllers 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. The E-Family extends the S12X product

range up to 1MB of Flash memory with increased I/O capability in the 208-pin version of the flagship

MC9S12XE100.
