Descripción
Each module can send and receive, at least 2 can be used. nRF24LE1 is NORDIC's latest 1 low-cost and high-performance RF transceiver single chip embedded with microprocessors. NRF24LE1 is a single-chip wireless transceiver system designed for ultra-low power wireless applications. The chip integrates high-performance microprocessors (compatible with 8051 instructions),16KB Flash memory, 1KB data space (on-chip RAM),1KB NV nonvolatile memory space, 512 bytes NV nonvolatile data storage, low power oscillator, real-time counter, AES hardware encryption and other module functions, as well as a variety of power modes designed for low power consumption, support for hardware debugging, NRF24LE1 provide an ideal wireless protocol platform, with seamless connection protocol, high security, low power consumption and excellent performance of anti-interference.
high speed 8 bit processor:
The chip is embedded with a high-speed 8-bit processor that is compatible with Intel 805 instructions. It uses CCB's quality cycle, which is 12 times faster than traditional 8051.
Memory:
16KB Flash memory for treatment encryption function; 1KB on-chip RAM; 1KB non-volatile data memory; 512 bytes of rewritable non-volatile data memory
Multi-function I/O pin
With 15 IO pin ports, many on-chip hardware resources can be realized through programmable multi-function I/O, such as GPIO.SPI master, SPI slave, master-slave 2-wire interface, full duplex serial interface, PWM,ADC, strong analog, external interrupt, timer interrupt input
