MC9S12XEP100CVL(NXP Semiconductors) Beschreibung
Additional information about the MC9S12XEP100CVL: The new MC9S12XE Family of microcontrollers takes the innovation of today’s MC9S12XD Family a step further with the introduction of new features to deliver 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, a Frequency Modulated Phase Locked Loop (IPLL) and a faster ATD. The E Family will extend the S12X product range up to 1MB of Flash memory with increased I/O capability in the 208-pin version of the flagship MC9S12XEP100. Targeted at automotive multiplexing and generic auto body applications, S12XE Family will deliver 32-bit performance with all the advantages and efficiencies of a 16-bit MCU. It will retain the low cost, power consumption, EMC and codesize efficiency advantages currently enjoyed by users of Freescale’s existing 16-bit S12 and S12X MCU families. There is a high level of compatibility between the S12XE and S12XD families. Like members of other S12X families, the S12XE Family will run 16-bit wide accesses without wait states for all peripherals and memories. The S12XE Family features an enhanced version of the performance-boosting XGATE co-processor which is programmable in “C” language and runs at twice the bus frequency of the S12X with an instruction set optimized for data movement, logic and bit manipulation instructions and which can service any peripheral module on the device. The new enhanced version has improved interrupt handling capability and is fully compatible with existing XGATE module. As with the S12XD Family, the S12XE Family features an enhanced MSCAN module which, when used in conjunction with XGATE, delivers FULL CAN performance with virtually unlimited number of mailboxes and retains backwards compatibility with the MSCAN module featured on existing S12 products. The S12XE Family has full 16-bit data paths throughout. The non-multiplexed expanded bus interface available on the 144- pin versions allows an easy interface to external memories. In addition to the I/O ports available in each module, up to 25 further I/O ports are available with interrupt capability allowing wake-up from STOP orWAIT mode. The S12XE Family is available in 208-Pin MAPBGA, 144-pin LQFP (both with optional external bus), 112-pin LQFP or 80-Pin QFP options.
