Application Notes,

Flash
The HCS12 family of microcontrollers is the next
generation of the highly successful 68HC12 architecture.
Using Freescale Semiconductor's 0.25 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 (I
2
C) and a 10-bit analog
to digital converter (ADC).
