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
