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 MC9S12DJ64 is part of a pin-compatible
family that scales from 32 KB to 512 KB of
Flash memory. The DJ64 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.
On-Chip Debug Interface
> Dedicated serial debug interface
> On-chip breakpoints
> Real-time in-circuit emulation and debug
without expensive and cumbersome box
emulators
> Read/write memory and registers while
running at full speed
Network Modules
> One msCAN module implementing the CAN
2.0 A/B protocol
• Five receive buffers per module with FIFO
storage scheme
• Three transmit buffers per module with
internal prioritization
> One J1850 module
Integrated Third-Generation Flash Memory
> Programmable bit rate up to 1 Mbps
> FIFO receive approach superior for
event-driven networks
> Ability to send and receive messages across
an SAE J1850 serial communication network
> 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
> Flash granularity—512 byte Flash erase/
2 byte Flash program
> 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 cost
through ultra-fast programming
> No external high voltage or charge
pump required
> Virtual EEPROM implementation, Flash array
usable for EE extension
