Jennic’s JN5139 brings 32-bit computing to ZigBee Pro. It’s built around a 32-bit, 16 MIPS RISC core, 96 kbytes of RAM, and 192 kbytes of ROM. Developers can use the JenNet stack, 6LoWAPAN IP, or ZigBee Pro protocol stack. Peripherals include 21 GPIO, I2C, SPI, two serial ports, a four-channel, 12-bit analog-to-digital converter (ADC), and dual 11-bit digital-toanalog converters (DACs). A 48-byte one-time programmable (OTP) eFuse stores the MAC ID. The chip supports 128-bit AES encryption. On-chip voltage regulation handles 2.2- to 3.6-V inputs. The JN5139 comes in an 8- by 8-mm, 56-lead quad flat no-lead (QFN) package. It can be found on the four modules in the JN5139 development kit, which includes a GNU-based toolchain and a copy of Daintree Networks’ Sensor Network Analyser. The JN5139-EK000 development kit costs $449.
