PICs get more analogue integration

May 09, 2013 // By Graham Prophet
8-bit MCUs from Microchip feature on-chip 12-bit ADC, Op Amps, high-performance 16-bit PWMs and high-speed comparators; advanced analogue and digital integration is combined with low power consumption, enabling self-sustaining smart control loops with minimal CPU intervention: use them in LED and other lighting applications, battery management, digital power supplies, motor control and general-purpose applications.

Microchip has announced an expansion of its 8-bit PIC16F178X enhanced Mid-Range core microcontroller (MCU) family with increased Flash memory densities; intelligent analogue and digital peripherals, such as on-chip 12-bit Analogue-to-Digital Converters (ADCs), 16-bit PWMs, 8-bit and 5-bit Digital-to-Analogue Converters (DACs), operational amplifiers, and high-speed comparators with 50 nsec response time; in addition to EUSART (including LIN), I 2C and SPI interface peripherals. The PIC16F178X are the first PIC MCUs to implement the new Programmable Switch Mode Controller (PSMC), which is an advanced 16-bit Pulse-Width Modulator (PWM) with 64 MHz operation and high-performance capabilities. This combination of features enables higher efficiency and performance, combined with cost and space reductions. The new MCUs also feature eXtreme Low Power (XLP) technology for active and sleep currents of 32 µA/MHz and 50 nA, respectively, helping to extend battery life and reduce standby current consumption. Low power consumption, in combination with advanced analogue and digital integration, make the PIC16F178X MCUs suitable for LED and other lighting applications, battery management, digital power supplies, motor control and general-purpose applications. In 28- and 40-pin packages, the MCUs’ intelligent analogue integration paired with Core Independent Peripherals, inclusive of the PSMC, DACs, Op Amps, high-speed comparators and 12-bit ADC, enable self-sustaining smart control loops with minimal CPU intervention. This allows for optimal application control while freeing the CPU to provide incremental application value, such as system health monitoring, communications, or human-interface control. Additionally, the MCUs feature a 32 MHz internal oscillator, 2 - 16K Words (3.5 - 28K Bytes) of Flash, 256 - 2K Bytes of RAM and 256 Bytes of data EEPROM.

Initial evaluation and development can begin with the F1 PSMC 28-pin Evaluation Board Platform (164130-10) priced at $19.99, as well as Microchip’s standard suite development tools.
