LPC2292/LPC2294

16/32-bit ARM microcontrollers with external memory interface

6.3 On-chip SRAM

On-chip SRAM may be used for code and/or data storage. The SRAM may be accessed

as 8-bit, 16-bit, and 32-bit. The LPC2292/LPC2294 provide 16 kB of SRAM.

6.4 Memory map

The LPC2292/LPC2294 memory maps incorporate several distinct regions, as shown in

Figure 4.

In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in either

ﬂash memory (the default) or on-chip static RAM. This is described in Section 6.19

“System control”.
