LPC2114/2124

Single-chip 16/32-bit microcontrollers

However, the ISP ﬂash erase command can be executed at any 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 LPC2114/2124 provide 16 kB of static RAM.

6.4 Memory map

The LPC2114/2124 memory maps incorporate several distinct regions, as shown in

Figure 3.

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 6.17

“System control”.
