The Feature-Rich Solution

That Makes Your Job Easier

The MCF5407 includes a rich array of

memory and integrated peripheral features

that help accelerate system design time

and reduce system cost. For example, two

programmable, full-duplex UARTs provide

serial communications channels. Four

channels of DMA enable fast data transfer

using a programmable burst mode independent

of processor execution. Two 16-bit multimode

timers provide separate input and output

signals. Other features include chip selects,

interrupt control, bus arbitration, a background

debug module (BDM) and an IEEE

1149.1

JTAG module. Available in a 208-pin QFP, this

device is pin-compatible with the MCF5307

and requires a 1.8-volt and 3.3-volt power

supply. It’s available right now, along with the

recommended M5407C3 evaluation board.
