MC9S12XDT256MAL数据手册恩XP中文资料规格书

描述 Description

Targeted for automotive multiplexing and mid-range body applications requiring flash from 64 KB to 512 KB, the MC9S12XD family gives you 32-bit performance (up to 80 MHz) with all the advantages and efficiencies of a 16-bit MCU.
The S12X provides low power consumption, excellent electromagnetic compatibility performance and code-size efficiency advantages.

特性 Features

• 16-bit HCS12X CPU
• Upward compatible with HCS12 instruction set
• Interrupt stacking and programmer's model identical to HCS12
• Instruction queue
• Enhanced indexed addressing
• Enhanced instruction set
• EBI (external bus interface)
• MMC (module mapping control)
• INT (interrupt controller)
• DBG (debug module to monitor HCS12X CPU and XGATE bus activity)
• BDM (background debug mode)
• XGATE
• Peripheral coprocessor
• Parallel processing module offloads the CPU by providing high-speed data processing transfer between peripheral modules, RAM and I/O ports
• Data transfer between flash EEPROM, peripheral modules and I/O ports
• Enhanced MSCAN module delivers full CAN performance with virtually unlimited number of mailboxes when used with XGATE
• Phase-lock loop (PLL) circuit allows power consumption and performance to be adjusted to suit operational requirements; system power consumption can be further improved with \"fast exit from stop mode\" feature
• I/O ports available in each module and up to 25 additional I/O ports are available with interrupt capability allowing wake-up from stop or wait mode
