Jennic's JN513x family provides performance, price and power improvements over its current JN5121 family at a sub $3 price target in 100k+ units.
In addition to the new silicon, Jennic has also released a range of modules, evaluation kits, software and protocol stacks.
Improvements over the existing solution include:
- Extended range thanks to a new modem architecture that provides 97dB receive sensitivity. It also has greater tolerance to carrier offset and EVM. Transmit power is improved to +3dbm. The JN513x family delivers a 100dB link budget and is specified over the full industrial temperature range and wide supply voltage.
- Deep sleep current consumption is 400nA allowing products waiting for a user-event to consume virtually no power. For an active part of a wireless sensor network, with on-chip oscillator and protocol timers running, sleep current consumption is under 2 microA. These sleep power consumption figures, in conjunction with the tight coupling of radio, protocol hardware and software on a single-chip wireless microcontroller provide extremely long battery life.
- Memory has been increased to 192k ROM and 96k RAM allowing full exploitation of the on-chip 32-bit RISC processor for complex applications and algorithms coupled with ZigBee or other mesh protocol stacks. Variants are available with 32k, 16k or 8kB RAM for simpler, low cost applications.
- The on-chip ROM includes the IEEE802.15.4 version B media access protocol layer, provision for a range of external serial EEPROM devices, over-the-air download, hardware abstraction layers and a simple serial interface. Embedding these features in ROM free up memory space for applications and allow simple dongle products at low cost. IEEE802.15.4B and ZigBee variants of the JN513x family are available.
- Each device shipped has a unique MAC address identifier allowing the saving of external FLASH devices. A further 256 bits of one-time-programmable memory is available for customers to programmed on-chip AES security keys and other unique identifiers.
- Package and pin-out of the JN513x remains the same as the first generation JN5121, allowing upgrade of current designs to second generation with no board changes.
A family of modules provides ceramic-antenna, SMA, and UFL connector options.
Standard power and high power modules are also available offering link budgets of 100dB and 119dB respectively. The standard module has demonstrated operation over 1km and the high-power module over 4km in open-space environments. Modules meet FCC, ETSI and TELEC regulations, reducing the effort needed to integrate Jennic devices into end products.
A new generation of evaluation kits is available. These provide a controller and four sensor units with a range of plug-in modules, offering power and antenna options. Users will now be able to evaluate different module types to suit their application and environment, with a range of site survey tools, including a customizable packet error rate measurement routine.
Jennic also offers a free, Integrated Developer Environment (IDE). This includes a new C compiler offering a 10 percent code density improvement.
JN513x products are now available for general sampling in a 56-pin QFN RoHS-compliant package. The JN513x product family includes the JN5139 wireless microcontroller with 192k ROM, 96k RAM at $3.50 in 100k quantities down to the JN5131 with 192k ROM, 8k RAM at $2.95 in 100k quantities.
