8-bit PICs boost analog features

29 May 2013 DSP, Micros & Memory

Microchip announced an expansion of its 8-bit PIC16F178X enhanced Mid-Range core microcontroller (MCU) family with increased Flash memory densities; intelligent analog and digital peripherals, such as on-chip 12-bit analog-to-digital converters (ADCs), 16-bit PWMs, 8-bit and 5-bit digital-to-analog converters (DACs), operational amplifiers and high-speed comparators with 50 ns response time; in addition to EUSART (including LIN), I²C 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. They also feature eXtreme Low Power (XLP) 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, in combination with advanced analog and digital integration, make the MCUs ideal for LED and other lighting applications, battery management, digital power supplies, motor control and general-purpose applications.

Available in 28- and 40-pin packages, the devices’ intelligent analog 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, 2-16 K Words (3,5–28 K Bytes) of Flash, 256-2 K Bytes of RAM and 256 Bytes of data EEPROM.
