Sheffield, UK Jennic has launched its JN513x family of wireless microcontrollers. IEEE802.15.4B
and ZigBee variants of the MCUs are available.
The company touts a sub $3 price target in 100K+ quantities for the MCUs. In addition to achieving this new price threshold the devices provide
performance, price and power improvements over the current JN5121 family.
Coupled with the release of the wireless microcontroller family is a range
of modules, evaluation kits, software and protocol stacks.
The JN513x family second generation wireless microcontrollers realizes a
number of improvements over the existing solution. The devices use a new modem architecture that provides 97dB receive sensitivity, and is more robust in noisier environments with greater tolerance to carrier offset and EVM. Transmit power is also improved to +3dbm. The JN513x family is the only single-chip wireless microcontroller with a 100dB link budget and 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. The memory available 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
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 programme 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 provide 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 are 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
Development tools and support
Developers can lower their tool investments and learning curves using a new
release of Jennic's free, Integrated Developer Environment. This includes a
new C compiler offering a 10 percent code density improvement.
Jennic's full range of application notes, reference designs and protocol
stacks will be fully functional with this second-generation product family
and are publicly available at www.jennic.com/support.
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. For
additional information, contact any Jennic sales representative or
authorized worldwide distributor.
