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

MC9S12DG256 is part of a pin-compatible

family that scales from 32 KB to 512 KB of Flash

memory. The MC9S12DG256 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-based electronic control units (ECUs), its

multiple network modules support this environment

by enabling highly efficient communications

between different network buses.

Network Modules

> Two msCAN modules implementing the CAN

2.0 A/B protocol

> Ability to link modules for higher

buffer count

• Five receive buffers per module with FIFO

storage scheme

> Programmable bit rate up to 1 Mbps

> FIFO receive approach superior for

event-driven networks

• Three transmit buffers per module with

internal prioritization

Integrated Third-Generation Flash Memory

> In-application reprogrammable

> Flexibility to change code in the field

> Efficient end-of-line programming

> Self-timed, fast programming

• Fast Flash page erase—20 ms

(512 bytes)

> Total program time for 256 KB code is less

than 10 seconds

• Can program 16 bits in 20 µs while

in burst mode

> Reduces production programming cost

through ultra-fast programming

> 5V Flash program/erase/read

> No external high voltage or charge

pump required

HCS12 CPU

> Flash granularity—512 byte Flash

erase/2 byte Flash program

> Virtual EEPROM implementation, Flash array

usable for EE extension

2 x SCI

> Four independently programmable

Flash arrays

256 KB Flash

> Can erase one array while executing code

from another

I²C

3 x SPI

> Flexible block protection and security

12 KB RAM

4 KB EEPROM

4 KB Integrated EEPROM

Vreg

5V to 2.5V

> Flexible protection scheme for protection

against accidental program or erase

> Can erase 4 bytes at a time and program

2 bytes at a time for calibration, security,

personality and diagnostic information
