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.
