Targeted at automotive multiplexing and mid-range body applications requiring flash from 64 KB to 512 KB, the MC9S12XD family delivers 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 EMC performance and code size efficiency advantages.
Features
- HCS12X Core
- 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)
- 16-bit HCS12X CPU
- 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 FullCAN performance with virtually unlimited number of mailboxes when used with XGATE
- 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
