• Manufacturer Part Number: nRF24E1
• Description: 2.4Ghz RF Transceiver With Embedded 8051 Compatible Microcontroller And 9 Input, 10 Bit ADC
• Manufacturer: Nordic VLSI

PRODUCT SPECIFICATION
The converter is by default configured as 10 bits. For special requirements, the AD
converter can be configured by software to perform 6, 8 or 12 bit conversions. The
converter may also be used in differential mode with AIN0 used as inverting input and
one of the other 7 external inputs used as noninverting input. In that case the
conversion time can be reduced to approximately 2 µs.
The transceiver part of the circuit has identical functionality to the nRF2401 single
chip RF transceiver. It is accessed through an internal parallel port and / or an internal
SPI. The data ready signals for each DuoCeiver™ receiver output can be programmed
as interrupts to the microcontroller or polled via a GPIO port.
nRF2401 is a radio transceiver for the world wide 2.4 - 2.5 GHz ISM band. The
transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a
modulator and two receiver units. Output power and frequency channels and other RF
parameters are easily programmable by use of the RADIO register, SFR 0xA0. RF
current consumption is only 10.5 mA in TX mode (output power -5dBm) and 18 mA
in RX mode. For power saving the transceiver can be turned on / off under software
control. Further information about the nRF2401 chip can be found at our website
