CHANDLER, Ariz. -- March 25, 2013

Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of
microcontroller, mixed-signal, analog and Flash-IP solutions, today announced
a new addition to its PIC12/16F15XX 8-bit microcontroller (MCU) family. The
low-cost, low pin count PIC12LF1552 is Microchip’s smallest (2x3 mm UDFN
package) and lowest-cost PIC^® MCU with hardware I^2C™ support, and includes a
four channel 10-bit Analog-to-Digital Converter (ADC) with hardware Capacitive
Voltage Divider (CVD) support for capacitive touch sensing. Additionally, this
new MCU features 3.5 KB Flash program memory, 256 Bytes RAM, a 32 MHz internal
oscillator, low-voltage operation from 1.8V to 3.6V, and low power consumption
for active and sleep currents of 50 µA/MHz and 20 nA, respectively.

The hardware CVD enables a more efficient implementation of capacitive sensing
for touch applications. This “Core-Independent Peripheral” includes additional
control logic that enables automated sampling, which reduces software size and
minimizes CPU usage. It also provides automatic control of guard-ring drive
and a programmable sample-and-hold capacitance, to better match larger touch
or proximity sensors. These capabilities, combined with the low cost and small
footprint of the PIC12LF1552, make it well suited for applications such as
temperature-monitoring devices, small remote controls (e.g., garage doors and
window blinds), smartphone buttons (e.g., input interfaces for Android™ and
Windows^® 8 phones utilizing hardware CVD), room light control (e.g.,
switching and dimming, both taking advantage of hardware CVD), and
coffeemakers (e.g., input interfaces and water-level monitoring, which both
could utilize the hardware CVD and the integrated communication capabilities),
among others.

“The low-cost PIC12LF1552 extends Microchip’s PIC12/PIC16F15XX family by
providing I^2C in our most compact 8-pin package, to address a wide variety of
space-constrained and cost-sensitive applications,” said Steve Drehobl, vice
president of Microchip’s MCU8 Division. “Designers can also make use of the
integrated hardware CVD to improve their design’s efficiency if capacitive
touch or proximity sensing is required.”

Development Support

Microchip’s full suite of development tools support the PIC12LF MCUs,
including the MPLAB^® X Integrated Development Environment (IDE), and PICkit™
3 (part # PG164130, $44.95), MPLAB REAL ICE™ In-Circuit Emulator (part #
DV244005, $499.98), and MPLAB^® ICD 3 (part # DV164035, $189.99) programmers.
Additionally, the MPLAB XC8 Compiler for 8-bit PIC MCUs  now supports this


The PIC12LF1552 MCU is offered in 8-pin PDIP, SOIC, MSOP and 2x3x0.5 mm UDFN
packages. It is available today for sampling and volume production.
