• Product introduction

MC9S12XA512CAA microcontroller

characteristic

• HCS12X core
  • 16-bit HCS12X CPU
    1. It is upward compatible with the instruction set of HCS12
    2. The interrupt stack and programmer model are the same as HCS12
    3. Instruction queue
    4. Enhanced variable addressing
    5. Enhanced instruction set
  • EBI (Foreign Bus Interface)
  • MMC (Module Mapping Control)
  • INT (Interrupt Controller)
  • DBG (debug module monitors HCS12X CPU and XGATE bus operation)
  • BDM (Background Debugging Mode)
• XGATE
  • Peripheral coprocessor
  • This parallel processing module reduces the load on the CPU by providing tuning data processing and transfer capabilities between peripheral modules, RAM, and I/O ports.
  • Flash data transfer PIT cycle interrupt timer between EEPROM, peripheral modules, and I/O ports
• PIT cycle interrupt timer
  • Four timers with pause periods
  • The pause period is at 1 and 2²⁴ Optional between bus clock cycles
• CRG
  • Low noise/low power Pierce oscillator
  • PLL
  • COP watchdog
  • Real-time outages
  • Clock monitoring
  • Quick wake-up in STOP mode
