Preliminary data sheet Rev. 01 — 22 June 2006 13 of 34 Philips Semiconductors LPC2880; LPC2888 16/32-bit ARM microcontrollers with external memory interface The flash is 128 bit wide and includes buffering to allow 3 out of 4 sequential read operations to operate without wait states. 6.1.3 On-chip static RAM The LPC2880/LPC2888 includes 64 kB of static RAM that may be used for code and/or data storage. 6.1.4 On-chip ROM 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: 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 6.2 Memory map The LPC2880/LPC2888 memory map incorporates several distinct regions, as shown in Figure 3. When an application is running, the CPU interrupt vectors are remapped to allow them to reside in on-chip SRAM. |
