Features
MC9S12XD Family, Rev. 2.16
Freescale Semiconductor 3
XGATE
• Programmable, high performance I/O co-processor module — up to
80 MIPS RISC performance
• Transfers data to or from all peripherals and RAM without CPU
intervention or CPU wait states
• Performs logical, shifts, arithmetic, and bit operations on data
• Enables FullCAN capability when used in conjunction with MSCAN
module
• Full LIN master or slave capability when used in conjunction with the
six integrated LIN SCI modules
• Can interrupt the HCS12X CPU signalling transfer completion
• Triggers from any hardware module as well as from the CPU possible
Memory Options
• 64K, 128K, 256K, 384K and 512K byte Flash
• 128K and 256K ROM
• Flash General Features
– Automated program and erase algorithm
– Fast sector erase and word program operation
– 2-stage command pipeline for faster multi-word program times
– Sector erase abort feature for critical interrupt response
– Protection scheme to prevent accidental program or erase
– Automated program and erase algorithm
– Fast sector erase and word program operation
– 2-stage command pipeline for faster multi-word program times
– Sector erase abort feature for critical interrupt response
– Protection scheme to prevent accidental program or erase
• 4K, 8K, 12K, 14K, 16K, 20K, 32K Byte RAM
Oscillator (OSC_LCP)
• Loop control Pierce oscillator using a 0.5 MHz to 16 MHz crystal
• Option for full-swing Pierce without internal feedback resistor using a
0.5 MHz to 40 MHz crystal
• Current gain control on amplitude output
– Signal with low harmonic distortion
– Low power
– Good noise immunity
– Eliminates need for external current limiting resistor
• Transconductance sized for optimum start-up margin for typical
crystals
• Clock monitor
