The JN5169 from NXP Semiconductor is an ultra-low-power, high-performance wireless microcontroller suitable for ZigBee applications. It features 512 kB embedded Flash, 32 kB RAM, and 4 kB EEPROM memory, allowing OTA upgrade capability without external memory. The 32-bit RISC processor offers high coding efficiency through variable width instructions, a multi-stage instruction pipeline, and low-power operation with programmable clock speeds. It also includes a 2.4 GHz, IEEE802.15.4 compliant transceiver and a comprehensive mix of analog and digital peripherals. The best-in-class RX operating current (down to 13 mA and with a 0.7 μA sleep timer mode) gives excellent battery life, allowing operation direct from a coin cell.
The peripherals support a wide range of applications. They include a two-wire, compatible I²C-bus and SPI-bus which can operate as either master or slave and a six-channel ADC with a battery monitor and a temperature sensor. It can support a large switch matrix of up to 100 elements, or alternatively, a 40-key capacitive touch pad.
