The #55 suffix specifically indicates tape-and-reel packaging for automated SMT assembly, while the core electrical specifications are identical to the R5F1026AASP. The RL78 core delivers 31 DMIPS at 24 MHz with class-leading power efficiency of 63 \u00b5A\/MHz in active mode and 230 nA in STOP mode. The device integrates an 11-channel 10-bit ADC, CSI\/UART\/I2C serial interfaces, and multiple 16-bit timers with PWM capability. The 2 KB data Flash supports background operation (BGO), allowing data logging without interrupting the main application. IEC\/UL 60730 Class B compliance libraries are available for household appliance safety certification.","working_principle":"The R5F1026AASP#55 operates identically to the R5F1026AASP. The RL78 16-bit CISC core with a 3-stage pipeline executes instructions at up to 24 MHz. The on-chip oscillator provides factory-trimmed frequencies from 1-24 MHz with \u00b11% accuracy. The ADC uses a successive approximation register architecture with an internal 1.45V reference for sensor measurements. Data Flash BGO allows simultaneous code execution and data Flash erase\/program operations. Multiple low-power modes (HALT, STOP, SNOOZE) minimize current consumption based on application activity level. The #55 suffix only differs in packaging format (tape-and-reel for production line automation) with no functional or electrical differences from the base R5F1026AASP part number.","pin_description":"<table border=\"1\"><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>ICSPCLK\/P12.0<\/td><td>ICSP Clock \/ Port 12 Bit 0<\/td><\/tr><tr><td>2<\/td><td>ICSPDAT\/P12.1<\/td><td>ICSP Data \/ Port 12 Bit 1<\/td><\/tr><tr><td>3<\/td><td>RESET\/P12.2<\/td><td>Reset Input \/ Port 12 Bit 2<\/td><\/tr><tr><td>4-5<\/td><td>P1.0-P1.1<\/td><td>Port 1 I\/O (ADC, timer, UART)<\/td><\/tr><tr><td>6-8<\/td><td>P1.2-P1.4<\/td><td>Port 1 I\/O (ADC, CSI, timer)<\/td><\/tr><tr><td>9<\/td><td>VSS<\/td><td>Ground<\/td><\/tr><tr><td>10<\/td><td>VDD<\/td><td>Supply Voltage (1.8-5.5V)<\/td><\/tr><tr><td>11-14<\/td><td>P1.5-P1.7, P0.0<\/td><td>Port I\/O (ADC, I2C, UART, timer)<\/td><\/tr><tr><td>15-18<\/td><td>P0.1-P0.4<\/td><td>Port I\/O (ADC, timer, CSI, UART)<\/td><\/tr><tr><td>19-20<\/td><td>P0.5-P0.6<\/td><td>Port I\/O (ADC, timer, interrupt)<\/td><\/tr><\/table>","application_scenarios":"<ul><li><b>Mass Production Assembly<\/b>: Tape-and-reel (#55) packaging for automated pick-and-place SMT lines producing high-volume home appliance controller boards<\/li><li><b>Smart Toilet<\/b>: RL78\/G12 sub-MCU controlling seat heater, bidet, and dryer with 230 nA STOP mode extending battery life in wireless models<\/li><li><b>Gas Water Heater<\/b>: 11-channel ADC monitoring thermocouple and gas valve sensors with IEC\/UL 60730 safety compliance for household certification<\/li><li><b>Air Purifier<\/b>: ADC sampling PM2.5 and VOC sensors with data Flash storing calibration curves updated via BGO<\/li><li><b>Smoke Detector<\/b>: Ultra-low-power SNOOZE mode with periodic ADC wake-up for photoelectric smoke sensor sampling<\/li><\/ul>","alternative_models":"<table border=\"1\"><tr><th>Model<\/th><th>Brand<\/th><th>Flash<\/th><th>Core<\/th><th>Package<\/th><\/tr><tr><td>R5F1026AASP<\/td><td>Renesas<\/td><td>16 KB<\/td><td>RL78<\/td><td>LSSOP-20<\/td><\/tr><tr><td>R5F102AAASP<\/td><td>Renesas<\/td><td>8 KB<\/td><td>RL78<\/td><td>LSSOP-20<\/td><\/tr><tr><td>PIC16F18323-I\/SN<\/td><td>Microchip<\/td><td>7 KB<\/td><td>PIC16<\/td><td>SOIC-14<\/td><\/tr><tr><td>STM8S003F3P6TR<\/td><td>ST<\/td><td>8 KB<\/td><td>STM8<\/td><td>TSSOP-20<\/td><\/tr><tr><td>MSP430G2553IPW20<\/td><td>TI<\/td><td>16 KB<\/td><td>MSP430<\/td><td>TSSOP-20<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8519","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=8519"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8519\/revisions"}],"predecessor-version":[{"id":8520,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8519\/revisions\/8520"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=8519"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=8519"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=8519"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=8519"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
