Most instructions execute in a single cycle (200 ns at 20 MHz). The internal oscillator is factory-calibrated to \u00b11% and supports software-selectable frequencies from 8 MHz down to 125 kHz, enabling dynamic clock switching for power optimization. The nanoWatt technology achieves 50 nA standby current in Sleep mode. The dual comparators can be configured with an internal programmable voltage reference (CVREF) derived from VDD, eliminating external reference components. The EUSART supports full-duplex asynchronous communication with LIN 2.0\/2.1 protocol support, auto-baud detection, and auto-wake on start bit for low-power serial communication. The 10-bit ADC uses a successive approximation register (SAR) with 8 multiplexed input channels. The Interrupt-on-Change feature on select pins enables efficient event-driven processing without polling.","pin_description":"<table>\n<tr><th>Pin Group<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>Power<\/td><td>VDD (1), VSS (14)<\/td><td>Power<\/td><td>Supply (2.0-5.5V) and ground<\/td><\/tr>\n<tr><td>Reset<\/td><td>MCLR\/VPP (4)<\/td><td>Input<\/td><td>Master clear \/ programming voltage<\/td><\/tr>\n<tr><td>OSC<\/td><td>OSC1\/CLKIN (2), OSC2\/CLKOUT (3)<\/td><td>I\/O<\/td><td>External oscillator or clock<\/td><\/tr>\n<tr><td>ADC<\/td><td>RA0\/AN0-RA3\/AN3, RC0\/AN4-RC3\/AN7<\/td><td>I\/O<\/td><td>8 analog input channels<\/td><\/tr>\n<tr><td>Comparator<\/td><td>RA0\/C12IN0+, RA1\/C12IN1-, RC0\/C2IN+, RC1\/C2IN-<\/td><td>I\/O<\/td><td>Dual comparator inputs<\/td><\/tr>\n<tr><td>EUSART<\/td><td>RC4\/TX\/CK, RC5\/RX\/DT<\/td><td>I\/O<\/td><td>Enhanced USART with LIN<\/td><\/tr>\n<tr><td>CVREF<\/td><td>RA2\/VREF<\/td><td>I\/O<\/td><td>Comparator voltage reference output<\/td><\/tr>\n<tr><td>Debug<\/td><td>RA0\/ICSPDAT, RA1\/ICSPCLK<\/td><td>I\/O<\/td><td>ICSP programming (shared with analog)<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>Industrial sensor nodes: digital voltage meters, temperature monitors<\/li>\n<li>Smart appliance controllers with LIN bus communication<\/li>\n<li>Battery-powered portable instruments with nanoWatt sleep<\/li>\n<li>Automotive sub-system controllers with LIN\/RS-485<\/li>\n<li>Simple motor and actuator control with comparator feedback<\/li>\n<\/ul>","alternative_models":"<table>\n<tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr>\n<tr><td>Microchip<\/td><td>PIC16F688-I\/ST<\/td><td>TSSOP-14<\/td><td>Same die, thinner package<\/td><\/tr>\n<tr><td>Microchip<\/td><td>PIC16F1829-I\/SL<\/td><td>SOIC-14<\/td><td>Enhanced mid-range, more peripherals<\/td><\/tr>\n<tr><td>Microchip<\/td><td>PIC16F1783-I\/SL<\/td><td>SOIC-14<\/td><td>With DAC and op-amp, more analog<\/td><\/tr>\n<tr><td>Microchip<\/td><td>ATtiny404-SSN<\/td><td>SOIC-14<\/td><td>AVR alternative, 20MHz, 4KB<\/td><\/tr>\n<tr><td>TI<\/td><td>MSP430G2553IRSA16<\/td><td>QFN-16<\/td><td>16-bit ultra-low-power alternative<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6685","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=6685"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6685\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6685"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6685"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6685"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6685"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
