It talks I²C to the host MCU, keeps time down to 0.885 µA at 3.3 V, and runs on anything from 0.9 V to 5.5 V. That means it can ride a coin cell through a power loss and still tick when the main rail is dead. On-chip alarm, leap-year compensation, and a watchdog timer save you an external supervisor IC and a few passives. No NRND or EOL flags on record. No minimum-buy pressure for prototype quantities; volume pricing is a conversation.","metaTitle":"NXP PCF85263ATL/AX RTC Clock/Calendar, I2C, 0.885µA, 10-DFN","metaDescription":"NXP PCF85263ATL/AX real-time clock with I²C interface, 0.885 µA timekeeping at 3.3 V, alarm, watchdog, industrial temp range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Clock/Calendar","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Alarm, Leap Year, Watchdog Timer","Interface":"I²C, 2-Wire Serial","Date Format":"YY-MM-DD-dd","Time Format":"HH:MM:SS:hh (12/24 hr)","Mounting Type":"Surface Mount","Package / Case":"10-XFDFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"0.9V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"10-DFN (2.6x2.6)","Voltage - Supply, Battery":"0.9V ~ 5.5V","Current - Timekeeping (Max)":"0.885µA @ 3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.27","priceTiers":[{"qty":1,"price":"$1.27000","currency":"USD"},{"qty":10,"price":"$1.13800","currency":"USD"},{"qty":25,"price":"$1.08040","currency":"USD"},{"qty":100,"price":"$0.88740","currency":"USD"},{"qty":250,"price":"$0.82952","currency":"USD"},{"qty":500,"price":"$0.73306","currency":"USD"},{"qty":1000,"price":"$0.57873","currency":"USD"},{"qty":4000,"price":"$0.54015","currency":"USD"},{"qty":8000,"price":"$0.51314","currency":"USD"},{"qty":12000,"price":"$0.49385","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/51b4befd785da2ada9fdcbdb3fa40815.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/PCF85263ATL%2FAX/alternatives.json"},"ai":{"faq":[{"question":"Does PCF85263ATL/AX have an alarm output?","answer":"Yes, the part includes an Alarm feature.
