MC9S12DJ256FS Datasheet PDF - Freescale Semiconductor

Overview
Freescale Semiconductor’s HCS12 family of microcontrollers (MCUs) is the next generation of the highly successful 68HC12 architecture. Using Freescale’s industry-leading 0.25 µs Flash, the MC9S12DJ256 is part of a pin-compatible family that scales from 32 KB to 512 KB of Flash memory. The DJ256 provides an upward migration path from Freescale’s 68HC08, 68HC11 and 68HC12 architectures for applications that need larger memory, more peripherals and higher performance. Also, with the increasing number of CAN/J1850-based electronic control units (ECUs), its multiple network modules support this environment by enabling highly efficient communications between different network buses.
