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
