LPC2387

Single-chip 16-bit/32-bit microcontroller

7.3 On-chip SRAM

The LPC2387 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 and an 16 kB SRAM

associated with the USB device 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.

7.4 Memory map

The LPC2387 memory map incorporates several distinct regions as shown in Figure 3.

In addition, the CPU interrupt vectors may be remapped to allow them to reside in either

ﬂash memory (default), boot ROM, or SRAM (see Section 7.25.6).
