Jennic JN5142 Datasheet

Overview
The JN5142 is an ultra low power, high performance wireless
microcontroller suitable for Remote Control, IEEE802.15.4 and Active RFID
applications. There is also a ROM variant that supports 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 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 0.5µA sleep timer give excellent battery life.
