Microchip Expands Low Pin Count, General-Purpose 8-bit PIC® Microcontroller Family for Safety-Critical Applications
CHANDLER, Ariz. --(Business Wire)--
Microchip Technology (News - Alert) Inc. (NASDAQ: MCHP), a leading provider of
microcontroller, mixed-signal, analog and Flash-IP solutions, today
announced from Embedded World an expansion of its 8-bit PIC®
microcontroller (MCU) portfolio, with the peripheral-rich, low pin count PIC16(L)F161X
family. These new MCUs expand the offering of Microchip's Core
Independent Peripherals (CIP), which offload timing-critical and
core-intensive tasks from the CPU, allowing it to focus on other
application tasks. Additionally, this family integrates fault-detecting
hardware features to assist engineers in developing safety-critical

The PIC16(L)F161X family offers a variety of key features, including the
Windowed Watchdog Timer (WWDT), which monitors proper software operation
within predefined limits, improving reliability. The Cyclic Redundancy
Check with Memory Scan (CRC/SCAN) detects and scans memory for corrupted
data. This family also includes a Hardware Limit Timer (HLT), which
detects hardware fault conditions (stall, stop, etc.), simplifying
closed-loop-control applications. These peripherals make it easier for
designers to implement safety standards (e.g., UL & class B) or
In addition to the HLT, the PIC16(L)F161X features the unique, 24-bit
Signal Measurement Timer (SMT). The SMT performs high-resolution
measurements of any digital signal, in hardware, resulting in more
precise and accurate measurements. This is ideal for speed control,
range finding and RPM indicators. Both timers are designed to reduce
design complexity, by eliminating the need for additional code and
This high level of integration makes these MCUs appealing to a broad
range of applications, such as monitoring and fail-safe systems (e.g.,
industrial machinery, power supplies), and products with variable-speed
motor control (e.g., fans, home appliances). Additionally, these are the
first PIC MCUs to offer hardware Zero Cross Detect (ZCD), which is
essential for designers looking to simplify TRIAC control and increase
system robustness by minimizing the EMI caused by switching transients.
A Complementary Waveform Generator (CWG), comparators, 10-bit ADC (News - Alert), 8-bit
DAC and Capture/Compare PWM are also integrated, to enable design
flexibility and overall cost reduction. The CWG can generate
complementary waveforms with fine control of key parameters, such as
polarity, dead band and emergency-shutdown states. It provides a
cost-effective solution for half-bridge and full-bridge drive control,
which saves both board space and component cost when driving FETs in
motor-control and power-conversion applications. All of these features
are provided in small-form-factor packages, ranging from 8 to 14 pins.
"The implementation of safety and control in an embedded system often
requires extensive code and additional components," said Steve Drehobl,
vice president of Microchip's MCU8 Division. "The PIC16F161X family
helps alleviate that complexity, by integrating specialized and flexible
features that speed designs while reducing system cost."
The PIC16(L)F161X family is supported by Microchip's standard suite of
world-class development tools, including the MPLAB®
ICD 3 (part # DV164035, $189.99) and PICkit™
3 (part # PG164130, $44.95) programmer/debuggers, along with the PICkit™
3 Low Pin Count Demo Board (part # DM164130-9, $25.99).
Pricing & Availability
The PIC12(L)F1612 MCUs are available today for sampling and volume
production in 8-pin PDIP, SOIC, and 3 mm x 3 mm DFN and UDFN packages.
The PIC16(L)F1613 MCUs are also available today in 14-pin PDIP, SOIC,
TSSOP, and 4 mm x 4 mm UQFN and QFN packages. Pricing for the family
starts at $0.53 each, in 10,000-unit quantities.
