Preliminary data sheet
6.1.3 On-chip static RAM
6.1.4 On-chip ROM
6.2 Memory map
The flash is 128 bit wide and includes buffering to allow 3 out of 4 sequential read
operations to operate without wait states.
The LPC2880/LPC2888 includes 64 kB of static RAM that may be used for code and/or
data storage.
The LPC2880/LPC2888 includes an on-chip ROM that contains boot code. Execution
begins in on-chip ROM after a Reset.
The boot code in this ROM reads the state of the mode inputs and accordingly does one
of the following:
The LPC2880/LPC2888 memory map incorporates several distinct regions, as shown in
Figure
them to reside in on-chip SRAM.
1. Starts execution in internal flash
2. Starts execution in external memory
3. Performs a hardware self-test, or
4. Downloads code from the USB interface into on-chip RAM and transfers control to the
downloaded code
3. When an application is running, the CPU interrupt vectors are remapped to allow
16/32-bit ARM microcontrollers with external memory interface
