From the Freescale WEB documentation:
"If you find yourself needing a little more memory than what the 56F8365 has to offer, or simply need to interface to other devices in your system a parallel fashion, then the 56F8366 is the device for you. Moving to this
144-pin LQFP package allows you to take advantage of its included external memory interface for these additional tasks. You will still enjoy 576 KB of on-chip Flash memory, pulse-width modulation (PWM) outputs, analog-to-digital converter (ADC) inputs and time channels, along with the capability of interfacing with other devices in your system."What is right with this? I hope their silicon designs receive more scrutiny than their WEB site.
