nRF24LE1 Preliminary Product Specification
The nRF24LE1 contains two separate RAM blocks. These blocks are used to save temporary data or pro-
grams.
The MCU internal RAM (IRAM) is the fastest and most flexible, but with only 256 bytes it is very limited.
To accommodate more temporary storage of data or code the nRF24LE1 has an additional 1024x8bit
(1kB) SRAM memory block default located in the XDATA address space from address 0x0000 to 0x03FF.
The location of the SRAM blocks in the MCU address space can be changed, see
A special feature of the nRF24LE1 SRAM block is that it is composed of two physical 512 byte blocks
called DataRetentive (lower 512 bytes) and DataNonRetentive. DataRetentive, in contrast to DataNonRe-
tentive, keeps its memory content during the Memory Retention power down modes (see
page
7.1
It is possible to configure the location in address space of each SRAM block as described in
Revision 1.1

102).
