AUSTIN, Texas, Dec 14, 2009 (BUSINESS WIRE) -- Addressing the need for energy efficiency in power-sensitive
applications, Silicon
Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, has introduced the industry's lowest
power microcontroller (MCU) family. Silicon Labs' ultra-low-power
C8051F91x/0x MCUs dramatically increase battery life in portable designs
and other power-sensitive embedded systems. The new F91x/0x MCUs are
ideal for a wide range of applications where low power consumption is
critical such as smart meters, RFID tags, personal medical devices,
sensor interfaces, energy harvesting, home security systems, and smoke
and fire detectors.
Consuming the industry's lowest current in common modes of operation,
the 8-bit F91x/0x MCUs enable the lowest system-level power consumption
in the embedded market. The power-efficient MCUs offer the lowest active
mode current consumption (160 microamps per MHz), which saves power when
the system is running. They also consume the lowest current in sleep
mode, either with an active real-time clock and brown-out detect circuit
(300 nanoamps) or without a real-time clock or brown-out detect circuit
operating (10 nanoamps) while maintaining full RAM retention.
"When evaluating MCU alternatives, power-conscious system designers
should assess a combination of active and sleep mode currents," said
Tony Massimini, chief of technology at Semico Research Corporation.
"Silicon Labs has designed its F91x/0x MCU family to deliver impressive
low power consumption in both modes. In addition, the new MCU family
taps into an extensive code base and offers an ideal memory size and
peripheral set for optimal cost and power efficiencies."
In systems that use sleep modes, a significant amount of power can be
wasted waking up the MCU and preparing it to acquire or process data.
The F91x/0x family has been designed to wake up in an extremely short
amount of time (less than two microseconds), minimizing the amount of
time spent in an energy-wasting state. These industry-leading low-power
specifications enable manufacturers to either extend the battery
lifetime of their end products or potentially use smaller batteries,
saving additional system cost.
"Silicon Labs' F91x/0x family leapfrogs other competitive MCUs by
providing the lowest current in common operating modes without
sacrificing performance, features or specifications," said Mark
Thompson, vice president of Silicon Laboratories. "No other MCU vendor
matches Silicon Labs' best-in-class power consumption in both sleep and
active modes, further establishing our leadership in ultra-low-power
MCUs for power-sensitive applications."
The F91x/0x MCUs expand Silicon Labs' award-winning C8051F9xx
MCU family by offering cost-effective 8 kB and 16 kB flash memory
options while providing 25 MIPS core performance and advanced analog
peripherals such as an on-chip 12-bit analog-to-digital (ADC) converter
with an autonomous power-saving burst mode. Silicon Labs'
ultra-low-power F9xx family MCUs are software and footprint compatible,
enabling developers to use one board layout and code set while migrating
to lower-cost designs.
The F91x/0x MCUs integrate a highly efficient dc-to-dc converter
designed to operate down to 0.9 V, enabling low-cost AA or AAA battery
operation, which supports smaller form factors, reduces system cost and
provides an innovative way to extend battery life. In addition, the
dc-to-dc converter can supply up to 65 mW of output power to drive other
system components such as LEDs, RF transceivers and sensors, creating a
true single-battery system solution. This environmentally friendly,
low-voltage capability ultimately helps consumers save money by reducing
the number of batteries required for a given application by half.
Unparalleled Development Support
Silicon Labs' comprehensive development tools help speed design and
accelerate market entry. The F91x/0x family is supported by the
full-featured C8051F912 development kit, F912-based ToolStick
and optional ToolStick Programming Adapters. C8051F9xx example code and
Silicon Labs' battery
life estimator GUI, a tool that helps designers optimize power, are
also available at www.silabs.com/pr/lowpower
and as part of each CD that ships with the development kit.
The ultra-low-power F91x/0x MCUs can be paired with Silicon Labs' CP240x
liquid crystal display (LCD) drivers for power-sensitive designs that
require LCDs such as thermostat displays, home security systems and
personal medical devices. In addition, developers can combine an F91x/0x
MCU with Silicon Labs' EZRadioPRO(R)
wireless receivers for use in wireless nodes for weather stations,
water and gas meters, home automation and security systems. Silicon Labs
offers an RF-to-USB reference design that demonstrates sub-gigahertz,
USB and low-power technologies for F91x/0x-based platforms.
Pricing and Availability
The C8051F91x/0x family is available in a compact, 24-pin 4x4 mm
package, which is ideal for space-constrained applications. Pricing for
the C8051F91x MCUs starts at $1.69 in 10K quantities, and F90x 10K
