Functional description
7.1 On-chip flash programming memory
The LPC1315/16/17/45/46/47 contain up to 64 kB on-chip flash program memory. The
flash can be programmed using In-System Programming (ISP) or In-Application
Programming (IAP) via the on-chip boot loader software. Flash updates via USB are
supported as well.
The flash memory is divided into 4 kB sectors with each sector consisting of 16 pages.
Individual pages of 256 byte each can be erased using the IAP erase page command.
7.2 EEPROM
The LPC1315/16/17/45/46/47 contain 2 kB or 4 kB of on-chip byte-erasable and
byte-programmable EEPROM data memory. The EEPROM can be programmed using
In-Application Programming (IAP) via the on-chip boot loader software.
7.3 SRAM
The LPC1315/16/17/45/46/47 contain a total of 8 kB, 10 kB, or 12 kB on-chip static RAM
memory.
7.4 On-chip ROM
The on-chip ROM contains the boot loader and the following Application Programming
Interfaces (APIs):
In-System Programming (ISP) and In-Application Programming (IAP) support for flash
including IAP erase page command.
IAP support for EEPROM
USB API (HID, CDC, and MSC drivers) (LPC1345/46/47 only)
Power profiles for configuring power consumption and PLL settings
Flash updates via USB supported (LPC1345/46/47 only)
7.5 Memory map
The LPC1315/16/17/45/46/47 incorporates several distinct memory regions, shown in the
following figures. Figure 8 shows the overall map of the entire address space from the
user program viewpoint following reset. The interrupt vector area supports address
remapping.
The AHB peripheral area is 2 MB in size and is divided to allow for up to 128 peripherals.
The APB peripheral area is 512 kB in size and is divided to allow for up to 32 peripherals.
Each peripheral of either type is allocated 16 kB of space. This allows simplifying the
address decoding for each peripheral.
