LPC2478
Single-chip 16-bit/32-bit microcontroller
The Thumb set’s 16-bit instruction length allows it to approach higher density compared to
standard ARM code while retaining most of the ARM’s performance.
7.2 On-chip flash programming memory
The LPC2478 incorporates 512 kB flash memory system. This memory may be used for
both code and data storage. Programming of the flash memory may be accomplished in
several ways. It may be programmed In System via the serial port (UART0). The
application program may also erase and/or program the flash while the application is
running, allowing a great degree of flexibility for data storage field and firmware upgrades.
The flash memory is 128 bits wide and includes pre-fetching and buffering techniques to
allow it to operate at speeds of 72 MHz.
7.3 On-chip SRAM
The LPC2478 includes a SRAM memory of 64 kB reserved for the ARM processor
exclusive use. This RAM may be used for code and/or data storage and may be accessed
as 8 bits, 16 bits, and 32 bits.
A 16 kB SRAM block serving as a buffer for the Ethernet controller and a 16 kB SRAM
associated with the second AHB can be used for data and code storage. The 2 kB RTC
SRAM can be used for data storage only. The RTC SRAM is battery powered and retains
the content in the absence of the main power supply.
