Product data sheet
6.3 On-chip static RAM
6.4 Memory map
On-chip static RAM may be used for code and/or data storage. The SRAM may be
accessed as 8-bits, 16-bits, and 32-bits. The LPC2101/02/03 provide 2 kB, 4 kB or 8 kB of
static RAM.
The LPC2101/02/03 memory map incorporates several distinct regions, as shown in
Figure
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
“System
