NRF24LE1-F16Q32-R7

The nRF24LE1 is a member of the low-cost, high-performance family of intelligent 2.4 GHz RF transceivers with embedded microcontrollers. The nRF24LE1 is optimized to provide a single chip solution for ULP wireless applications. The combination of processing power, memory, low power oscillators, real-time counter, AES encryption accelerator, random generator and a range of power saving modes provides an ideal platform for implementation of RF protocols. Benefits of using nRF24LE1 include tighter protocol timing, security, lower power consumption and improved co-existence performance. For the application layer the nRF24LE1 offers a rich set of peripherals including: SPI, 2-wire, UART, 6 to 12 bit ADC, PWM and an ultra low power analog comparator for voltage level system wake-up. The nRF24LE1 comes in three different package variants: • An ultra compact 4×4mm 24 pin QFN (7 generic I/O pins) • A compact 5×5mm 32 pin QFN (15 generic I/O pins) • A 7×7mm 48 pin QFN (31 generic I/O pins) The 4×4mm 24 pin QFN is ideal for low I/O count applications where small size is key. Examples include wearable sports sensors and watches. The 5×5mm 32 pin QFN is ideal for medium I/O count applications such as wireless mouse, remote controls and toys. The 7×7mm 48 pin QFN is designed for high I/O count products like wireless keyboards.
