The PIC24F16KA family of four 16-bit microcontroller
products forms part of Microchip's growing nanoWatt XLP portfolio. This family
provides designers with high-performance, feature-rich low-power 16-bit
MCUs. The PIC24F16KA parts feature many
integrated peripherals, including a 10-bit ADC, Analog Comparators, Real-Time
Clock and Calendar (RTCC), capacitive touch sensing, and also on-chip
EEPROM. This industry-leading
combination of low power consumption and functionality makes these PIC MCUs
ideal for any battery-powered or power-constrained application. With
the April 2009 introduction of the PIC24F16KA family of 16-bit
microcontrollers, featuring nanoWatt XLP eXtreme Low Power Technology,
Microchip is providing microcontrollers with power consumption that is below long-standing
industry minimums, including sleep currents as low as 20 nA, which
enables battery life of up to 20 years. Additionally, they integrate peripherals not
commonly found in low-power microcontrollers, such as capacitive touch
sensing. The PIC24F16KA family has the
following features that make them the most battery-friendly MCUs in the world
according to the company: sleep modes
down to 20 nA; watchdog timer modes down to 370 nA; real time clock and calendar
mode down to 510 nA; low-power active mode down to 8 ÂµA; 1.8 to 3.6V operating
voltage for all on-chip analog and digital peripherals; max speed (32 MHz) at a
battery friendly 3.0V; higher speeds at lower, more battery-friendly voltages;
and higher instruction-set efficiency for lower power consumption. The company
says the low-power PIC24F16KA family is the most battery friendly MCUs in the
world for its maximum battery life for alkaline cells and lithium coin cells;
maximum performance from a battery; and its instruction-set efficiency improves
battery life. Two-speed startup also saves battery power.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
