MC9S12XA256CAA

The MC9S12XA256CAA is a 16-bit Microcontroller based on enhanced HCS12X CPU (40MHz bus) with CISC architecture operates at a maximum frequency of 80MHz. The device incorporates an enhanced XGATE co-processor, 256kB internal flash, 16kB internal RAM, 4kB EEPROM, 8-channel 10-bit A/D converter and 59 general-purpose I/O pins. This device also features peripherals like one inter-integrated circuit (IIC) bus module, three multi-scalable controller area networks (MSCAN) CAN 2.0 A/B software compatible modules, two serial communications interface (SCI) and two serial peripheral interface modules (SPI). Single-wire background debug mode (BDM) for debugging both S12X CPU and XGATE simultaneously while running at full speed.

• C-optimized CISC architecture produces extremely compact code
• Excellent 32-bit calculations and semaphore handling
• Access to large data segments independent of PPAGE
• Opcode compatible with the 68HC11, 68HC12 and HCS12
• Non-multiplexed external bus
• Windowed COP watchdog and clock monitor
• Seven levels of nested interrupt
• Real-time interrupt
• Enhanced capture timer
• Clock generation module - <gt/> PLL clock frequency multiplier/divider
• Periodic interrupt timer
• Programmable pull-ups/pull-downs
• Dual drive capability for EMC-optimized design
• Single-wire background debug mode (BDM)
• On-chip hardware breakpoints with no limitation on memory address
• Read/write memory and registers while running at full speed
