LPC2292/LPC2294

16/32-bit ARM microcontrollers with external memory interface

[1]

SSP interface available on LPC2292/2294/01 only.

6.6 Pin connect block

The pin connect block allows selected pins of the microcontroller to have more than one

function. Conﬁguration registers control the multiplexers to allow connection between the

pin and the on chip peripherals. Peripherals should be connected to the appropriate pins

prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any

enabled peripheral function that is not mapped to a related pin should be considered

undeﬁned.

6.7 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-bit, 16-bit, or 32-bit wide.
