LPC2210/2220
16/32-bit ARM microcontrollers with external memory interface
6.9 External memory controller
The external Static Memory Controller is a module which provides an interface between
the system bus and external (off-chip) memory devices. It provides support for up to four
independently configurable memory banks (16 MB each with byte lane enable control)
simultaneously. Each memory bank is capable of supporting SRAM, ROM, Flash EPROM,
Burst ROM memory, or some external I/O devices.
Each memory bank may be 8, 16, or 32 bits wide.
6.10 General purpose parallel I/O
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back, as well as the current state of the port pins.
6.10.1
Features
Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
6.11 10-bit A/D converter
The LPC2210/2220 contains a single 10-bit successive approximation analog to digital
converter with eight multiplexed channels.
6.11.1
Features
Measurement range of 0 V to 3 V.
Capable of performing more than 400,000 10-bit samples per second.
Burst conversion mode for single or multiple inputs.
Optional conversion on transition on input pin or Timer Match signal.

Controls whether P3.1/A1 is a port pin (0) or an address line (1).
27:25
Controls the number of pins among P3.23/A23/XCLK and P3[22:2]/A2[22:2] that
are address lines:
000 = None
100 = A11:2 are address lines.
001 = A3:2 are address lines. 101 = A15:2 are address lines.
010 = A5:2 are address lines. 110 = A19:2 are address lines.
011 = A7:2 are address lines. 111 = A23:2 are address lines.
