Data Sheet: JN5142-J01
JenNet-IP Wireless Microcontroller
Overview
The JN5142-J01 is an ultra low power, high performance wireless
microcontroller suitable for use in JenNet-IP Smart Devices. The JN5142
features an enhanced 32-bit RISC processor offering high coding efficiency
through variable width instructions, a multi-stage instruction pipeline and low
power operation with programmable clock speeds. It also includes a 2.4GHz
IEEE802.15.4 compliant transceiver, 128KB of ROM, 32KB of RAM, and a
comprehensive mix of analogue and digital peripherals. The JenNet-IP
network stack is embedded in the device ROM. The operating current is
below 18mA, allowing operation direct from a coin cell.
The peripherals support a wide range of applications. They include a 2-wire
serial interface, which operates as either master or slave, a two channel
ADC with battery and temperature sensors. A large switch matrix of up to 81
elements can be supported for remote control applications. The best in
class radio current and a 0.6µA sleep timer give excellent battery life.
