The MCF51CN128 Series Microcontrollers
1.1.1
Definition
The MCF51CN128 series microcontrollers are systems-on-chips (SoCs) that are based on the V1 ColdFire
core and:
•
Operate at processor core speeds up to 50.33 MHz (all peripherals except the SCIs operate at half
of this speed. SCIs are clocked at the CPU rate.)
•
Feature 10/100 BASE-T/TX fast ethernet controller (FEC) with media independent interface (MII)
to connect an external physical transceiver (PHY)
•
Multi-function external bus interface (Mini-FlexBus).
•
A collection of communications peripherals, including UART, IIC and SPI.
•
Integrated 12-bit SAR Analog-to-Digital Converter
These devices are ideal for low-cost ethernet-enabled applications, including smart-sensor applications.
