Cost-effective advanced analog, digital integration to 8-bit PIC microcontrollers

New Microchip MCUs feature On-Chip 12-bit ADC, 8-bit DAC, Op Amps, high-speed comparators, eXtreme low power technology; 16-bit PWM offers advanced control.


MicrochipMicrochip Technology Inc. announced from Design West in San Jose, Calif.,  the expansion of its 8-bit PIC16F(LF)178X enhanced Mid-range core microcontroller (MCU) family to include advanced analog and integrated communication peripherals, such as on-chip 12-bit Analog-to-Digital Converters (ADCs), 8-bit Digital-to-Analog Converters (DACs), operational amplifiers, and high-speed comparators, along with EUSART (including LIN), I2C and SPI interface peripherals.  The MCUs also feature the industry’s best level of advanced PWM control and accuracy via the new Programmable Switch-Mode Controllers (PSMCs).  This combination of features enables higher efficiency and performance, along with cost and space reductions in applications such as closed-loop control in power supplies, and lighting.  The “LF” versions of the MCUs feature eXtreme Low Power Technology, for active and sleep currents of just 32 µA/MHz and 50 nA, respectively, helping to extend battery life and reduce standby current consumption.  Low power consumption and advanced analog and digital integration make the general-purpose PIC16F(LF)178X MCUs ideal for LED lighting, battery management, digital power supply, motor control and other applications.

Environmental concerns and “green” initiatives have led to the rise of new energy-consumption legislation around the world. The PIC16F(LF)178X MCUs enable designers to create better products that consume less power.  Microchip’s enhanced Mid-range 8-bit core brings more performance, with 32 MHz operation, automatic context save for faster interrupt handling, more efficiency in the instruction set with better code density, plus faster and more direct-port control capabilities.  Available in 28- and 40-pin packages, the MCUs’ advanced analog integration includes an on-chip 12-bit ADC for very small voltage measurements, as well as enabling mTouch capacitive sensing; and an 8-bit DAC for high-resolution voltage references.  Also included on-chip are fast analog comparators with 50 nS response time, Capture Compare Peripherals, and I2C™, SPI and EUSART interfaces for communications.  Additionally, the MCUs feature a 32 MHz internal oscillator, 2 - 8K Words (3.5 - 14K Bytes) of Flash, 128 – 512 Bytes of RAM, and 256 Bytes of data EEPROM.  The PSMC peripherals are 16-bit Pulse-Width Modulators (PWMs) with 64 MHz operation and advanced control capabilities.

"The PIC16F(LF)178X family integrates considerable analog peripherals along with a versatile 8-bit PIC MCU,” said Steve Drehobl, vice president of Microchip’s Security, Microcontroller and Technology Development Division.  “This high analog integration enables designers to bring a new level of intelligence and flexibility to an ever-expanding assortment of applications, including those in the power-supply, power-management, motor-control and lighting markets, among others.”

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
