Features

Benefits

> 25 MHz operation at 3.3 V for 40 nsec

minimum instruction cycle time

> Object code compatible with the 68HC11

and 68HC12

> C-optimized architecture produces extremely

compact code

High-Performance 16-bit HCS12 CPU Core

> Single-wire background debug mode

> On-chip trace buffer with nine flexible trigger

modes and multiple hardware breakpoints

> Nonintrusive emulation

> Real-time emulation of MCU functions at full

operating voltage and frequency range

without the limitations of traditional emulators

> Real-time in-circuit emulation and debug

without expensive and cumbersome

“box” emulators

> Read/write memory and registers while

running at full speed

> Bus state analysis without the expense of a

traditional emulator

On-Chip Debug Interface

> In-application reprogrammable

> Self-timed, fast programming

• Fast Flash page erase—20 µs (512 bytes)

• Can program 16 bits in 20 µs while in

burst mode

> Internal program/erase voltage generation

> Flash granularity—512 byte Flash erase/

2 byte Flash program

> Flexible block protection and security

> Flexibility to change code in the field

> Efficient end-of-line programming

> Total program time for 64K code is less than

five seconds

> Reduces production programming cost

through ultrafast programming

> No external high voltage or charge

pump required

> Virtual EEPROM implementation, Flash

array usable for EE emulation

Application Notes,

Evaluation Boards and

Flash

The HCS12 family of microcontrollers is the next

generation of the highly successful 68HC12 architecture.

Using Freescale Semiconductor’s 0.25µ Flash, the

MC9S12NE64 provides an upward migration path from the

68HC08, 68HC11 and 68HC12 architectures for

applications that need larger memory, more peripherals and

higher performance.

The MC9S12NE64 provides a total Ethernet connectivity

solution in one microcontroller unit (MCU) with its integrated

Ethernet Media Access Controller (EMAC), 10/100

Ethernet physical layer (EPHY) and on-chip Flash memory.

Other features include two serial communications interfaces

(SCIs), a four-channel timer, a serial peripheral interface

(SPI), an inter-integrated circuit (I2C) and a 10-bit analog

to digital converter (ADC).
