LPC2101/02/03

Single-chip 16-bit/32-bit microcontrollers

6.3 On-chip static RAM

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.

6.4 Memory map

The LPC2101/02/03 memory map incorporates 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 6.17

“System control”.
