This ARMee-Board differ from earlier publications that instead of being based on an 8-bit device such as a PIC [1], AVR [2] or 8051 [3] controller, this design will use a 32-bit ARM microcontroller: the LPC210x from Philips Semiconductors. This device has just about everything you could want from a microcontroller, see the ‘ARMee & LPC210x Main Features’ inset. However, we should also mention that it lacks any ADC interface and an external bus interface. But then the LPC210x is a true microcontroller and has no external bus interface to extend the memory capabilities using external Flash or SRAM chips, or add new peripherals.
