nRF24LE1 Preliminary Product Specification
The IO pins of the nRF24LE1 are default set to general purpose IO for the MCU. The numbers of available
IOs are 7 for the 24 pin 4x4mm, 15 for the 32 pin 5x5mm and 31 for the 48 pin 7x7mm package. The IO
pins are also shared with IO requirements from peripheral blocks like SPI and 2 wire as well as more spe-
cialized functions like a 32 KHz crystal oscillator and the JTAG interface for the HW debugger. Connections
between these other peripheral blocks and the pins are made dynamically by the PortCrossbar module.
