Microchip Technology Inc recently
launched several new 8-bit PIC®
microcontrollers (MCUs) from the
Embedded Systems Conference in Boston.
The new MCUs feature configurable logic
and a high level of peripheral integration in
6- to 20-pin packages. The
PIC10F(LF)32X and PIC1XF(LF)150X
MCUs also incorporate new peripherals,
including Configurable Logic Cells
(CLCs), Complementary Waveform
Generators (CWGs) and Numerically
Controlled Oscillators (NCOs),
enabling functionality that was not
possible before with low pincount
MCUs. These general-purpose
MCUs enable designers to enhance
functionality, reduce design size, and
decrease the cost and power
consumption of products in the
appliance (e.g. small kitchen
appliances); automotive (e.g. interior
lighting); consumer (e.g. power
tools); and industrial markets (e.g.
utility meters), among others.
The CLC peripherals on the
PIC10F(LF)32X and PIC1XF(LF)150X MCUs
enable software control of combinational and
sequential logic, which increases the onchip
interconnection of peripherals and I/Os,
thereby reducing external components,
saving code space and adding functionality.
The CWG peripheral works with multiple
peripherals to generate complementary
waveforms with dead-band control and auto
shutdown, which provides improved
switching efficiencies. Additionally, the NCO
peripheral enables linear frequency control
and high resolution, which is required for
applications such as lighting ballast, tone
generation and other resonant control
circuits. The MCUs also feature low power
consumption, with currents of less than 30
µA/MHz in active mode, and less than 20 nA
in sleep; as well as an on-chip 16 MHz
internal oscillator, Analog-to-Digital
Converter (ADC), and up to 4 Pulse-Width
Modulation peripherals. An integrated
temperature-indicator module enables
low-cost temperature measurements.
"These new MCUs expand the reach
of the PIC10F, PIC12F and PIC16F
families, enabling new applications
for microcontrollers that didn't exist
before," said Steve Drehobl, vice
president of Microchip's Security,
Microcontroller and Technology
Development Division, in a release.
"They provide an unmatched
combination of unique functionality,
power consumption, size and cost."
