MC9S12DJ256
Target Applications
> Automotive applications
> Industrial control
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.
