The JN5169 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 ??A 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 2-wire compatible I2C-bus and SPI-bus which can operate as either master or slave, a 6-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.
