Overview
Freescale Semiconductor’s HCS12 Family ofmicrocontrollers (MCUs) is the next generation of the highly successful 68HC12 architecture.Using Freescale’s industry-leading 0.25 µs Flash, the MC9S12DG128 is part of a pin-compatiblefamily that scales from 32 KB to 512 KB of Flashmemory. The MC9S12DG128 provides anupward migration path from Freescale’s 68HC08,68HC11 and 68HC12 architectures forapplications that need larger memory, moreperipherals and higher performance. Also, withthe increasing number of CAN-based electroniccontrol units (ECUs), its multiple networkmodules support this environment by enablinghighly efficient communications between differentnetwork buses.Network ModulesOn-Chip Debug Interface
>Dedicated serial debug interface>On-chip breakpoints
>Real-time in-circuit emulation and debugwithout expensive and cumbersome box emulators>Read/write memory and registers while runningat full speed
>Two msCAN modules implementing the CAN2.0 A/B protocol•Five receive buffers per module with FIFOstorage scheme
•Three transmit buffers per module withinternal prioritization
Integrated Third-Generation Flash Memory
>Ability to link modules for higher buffer count >Programmable bit rate up to 1 Mbps>FIFO receive approach superior for event-driven networks
>In-application reprogrammable>Self-timed, fast programming •Fast Flash page erase—20 ms (512 bytes)
•Can program 16 bits in 20 µs while in burst mode
>5V Flash program/erase/read
>Flexibility to change code in the field>Efficient end-of-line programming >Total program time for 128 KB code is less than five seconds>Reduces production programming costthrough ultra-fast programming>No external high voltage or charge pump required>Virtual EEPROM implementation, Flash arrayusable for EE extension >Can erase one array while executing code from another
