概述

Description

MAX313LEUE+T is a Maxim/Analog Devices real-time clock (RTC) IC for embedded systems. It provides timekeeping with a calendar, alarms, and a timer, interfacing to microcontrollers via I2C/SMBus. The device typically uses a 32.768 kHz crystal for an accurate time base and supports battery-backup operation with an automatic power-fail switch and, often, a trickle-charge path for a backup source. Other common features include a programmable square-wave output, watchdog/interrupt options, and low-power operation suitable for battery-powered devices. The +T suffix usually indicates Tape-and-Reel packaging; UE denotes a specific package/temperature option (check the datasheet for exact details). Applications include data loggers, wearables, industrial controllers, and any system requiring persistent timekeeping when primary power is unavailable. For exact electrical specs, timing, and packaging, consult the latest MAX313LEUE+T datasheet.

Features

I don’t have the exact MAX313LEUE+T datasheet on hand, but typical features of MAX313xx RTCs include:
- 32.768 kHz crystal oscillator input with optional calibration
- Battery-backup operation (VBAT) and automatic power‑loss switching
- Full calendar/timekeeping: seconds, minutes, hours, day, date, month, year with leap-year support
- Alarms and programmable timer
- Interrupt outputs and programmable square-wave output
- Serial interface (I2C- or SPI-like 3-wire) for access to timekeeping registers
- Low current in RTC mode (low-power operation with fast wake-up options)
- Wide voltage range and extended temperature range for industrial/automotive use
- Small RoHS-compliant packaging (suffix LEUE/T indicates packaging)
Note: Please consult the official MAX313LEUE+T datasheet for exact specifications (voltage ranges, current consumption, interface mode, temperature range, and package details).

Package

Package: 8-pin MSOP (MSOP-8), RoHS-compliant. +T indicates Tape & Reel packaging.

Pinout

Pin count: 8 pins (8-pin package).
Function: Real-Time Clock/Calendar (RTC) with I2C/SMBus interface, often with alarm/timer features, 32 kHz output, and battery-backup for timekeeping when power is off.

Manufacturer

Manufacturer: Maxim Integrated Products (now part of Analog Devices, Inc.)
What kind of company: A semiconductor company that designs and manufactures analog, mixed-signal, and related integrated circuits (ICs).

Application

- Real-time clock/calendar for microcontroller systems needing low power and battery backup
- Data logging/meters with time-stamped measurements
