LPC2141/42/44/46/48
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-bit, 16-bit, and 32-bit. The LPC2141, LPC2142/44 and LPC2146/48
provide 8 kB, 16 kB and 32 kB of static RAM respectively.
In case of LPC2146/48 only, an 8 kB SRAM block intended to be utilized mainly by the
USB can also be used as a general purpose RAM for data storage and code storage and
execution.
6.4 Memory map
The LPC2141/42/44/46/48 memory map incorporates several distinct regions, as shown
in
Figure 5
.
In addition, the CPU interrupt vectors may be remapped 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”
.
