nRF24LE1 Preliminary Product Specification
The nRF24LE1 uses the same 2.4GHz GFSK RF transceiver with embedded protocol engine (Enhanced
ShockBurst™) that is found in the nRF24L01+ single chip RF Transceiver. The RF Transceiver is designed
for operation in the world wide ISM frequency band at 2.400 - 2.4835GHz and is very well suited for ultra
low power wireless applications.
The RF Transceiver module is configured and operated through the RF transceiver map. This register map
is accessed by the MCU through a dedicated on-chip Serial Peripheral interface (SPI) and is available in all
power modes of the RF Transceiver module.
The embedded protocol engine (Enhanced ShockBurst™) enables data packet communication and sup-
ports various modes from manual operation to advanced autonomous protocol operation. Data FIFOs in
the RF Transceiver module ensure a smooth data flow between the RF Transceiver module and the
nRF24LE1 MCU.
The rest of this chapter is written in the context of the RF Transceiver module as the core and the rest of
the nRF24LE1 as external circuitry to this module.
