Intelligent Analog Summary With Microchip’s Intelligent Analog solutions, engineers can reduce their component count, design smaller, more cost effective boards, and benefit from simplified, higher performance designs and easier procurement of components. In addition, designers benefit from increased flexibility like analog topology agility, utilizing the MCU’s programmable analog interconnects and programmability. To simplify your next design, Microchip has integrated the following Analog Peripherals. Op Amps A basic building block in electronic design. Integrating op amps into the Microcontroller offers increased flexibility and reliability while reducing BOM costs and board space. High Speed Comparators Comparators have be in the PIC Microcontroller lineup for many years. We are now offering feature rich High Speed (50 nS) variants to enable faster responding/more efficient closed loop feedback designs. Fixed Voltage Referrence Fixed Voltage Ref provides an integrated stable voltage reference, independent of VDD. Analog to Digital Conversion ■ 16, 12, 10 and 8-bit ADCs available in our 8-bit offering Digital to Analog Conversion ■ 9,8, and 5-bit DAC options available in our 8-bit offering High Current Sink/Source Pins High Current Sink/Source pins with the ability to sink/source 50 mA the high currents pins enable direct MOSFET drive from the microcontroller. Zero Cross Detect Enables the micro to be connected directly to the AC Featured Intelligent Analog Product Families Family Pins Flash Memory SRAM (Bytes) Intelligent Analog Core Independent Peripherals Additional Features PIC16F527/570 20/28 1.5K–3K 64–132 8-bit ADC (8), Comparator (2), Op amp (2) - PIC16F75X 8/14 1.75 KB–3.5 KB 64–128 10-bit ADC (4), 5/9-bit DAC (1), Comparators (2), Op amp (1), High Current Pins (2) CWG/COG Internal Shunt: providing high voltage input capability PIC16(L)F170X 14/20 3.5 KB–14 KB 256 B–1 KB 10-bit ADC (8-12), 8-bit DAC (1), Op amps (2), Comparators (2), Zero Cross Detect CLC,COG I2C™/SPI, UART PIC16(L)F171X 28/40/44 7 KB–28 KB 512–2 KB 10-bit ADC (17–28), 5 & 8-bit DAC, Op amps (2), Comparators (2), Zero Cross Detect CLC, NCO, COG I2C/SPI, UART PIC16(L)F178X 28/40/44 2K - 16K 256 - 2K 12-bit ADC (11–14), Comparators (3–4), Op amps (2–3), 8-bit DAC, 5-bit DAC (0–3) PSMC I2C/SPI, UART www.microchip.com/intelligentanalog input via a current limiting resistor. The ZCD will flag the micro when the Zero Cross is approaching so any required switching can be synchronized to reduce power and eliminate any switching related artifacts/noise.
