16/32-bit ARM microcontrollers
time (no matter whether the CRP is on or off). Removal of CRP is achieved by erasure of
full on-chip user flash. With the CRP off, full access to the chip via the JTAG and/or ISP is
restored.
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 LPC2212/2214 provide 16 kB of static RAM.
6.4 Memory map
The LPC2212/2214 memory maps incorporate several distinct regions, as shown in the
following figures.
In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in either
flash memory (the default) or on-chip static RAM. This is described in Section 6.18
“System control”.
