LPC2420/2460
Flashless 16-bit/32-bit microcontroller
The Thumb set’s 16-bit instruction length allows it to approach higher density compared to
standard ARM code while retaining most of the ARM’s performance.
7.2 On-chip SRAM
The LPC2420/2460 includes a SRAM memory of 64 kB reserved for the ARM processor
exclusive use. This RAM may be used for code and/or data storage and may be accessed
as 8 bits, 16 bits, and 32 bits.
A 16 kB SRAM block serving as a buffer for the Ethernet controller (LPC2460 only) and a
16 kB SRAM associated with the second AHB can be used both for data and code
storage, too. The 2 kB RTC SRAM can be used for data storage only. The RTC SRAM is
battery powered and retains the content in the absence of the main power supply.
7.3 Memory map
The LPC2420/2460 memory map incorporates several distinct regions as shown in
Table 5
and
Figure 4
.
In addition, the CPU interrupt vectors may be remapped to allow them to reside in either
boot ROM or SRAM (see
Section 7.25.6
).
