概述

Description

ISL12022MIBZ-T is an I2C real-time clock/calendar from Renesas/Intersil. It provides timekeeping (seconds to year) and calendar functions, typically using an external 32.768 kHz crystal. It features battery-backup operation with automatic switchover to VBAT, so timekeeping continues when main power is lost. It also includes non-volatile RAM (NV data), allowing storage of user data that is preserved during power outages. The device supports alarms and a programmable square-wave output, and is designed for low-power operation. The MIBZ part code refers to an 8-pin package, with the “-T” suffix indicating tape-and-reel packaging. Suitable for data loggers, meters, embedded systems, and other applications needing reliable timekeeping with power-fail protection.

Features

Key features of ISL12022MIBZ-T (brief):
- I2C real-time clock/calendar
- 32.768 kHz crystal input for accurate timekeeping with leap-year support
- Battery-backed operation to maintain time/data during power loss
- On-chip non-volatile RAM for user data storage
- Alarm and timer functions with programmable interrupt outputs
- Programmable square-wave output
- 8-pin MIBZ package; broad operating voltage and low power consumption
- Suitable for low-power embedded systems requiring reliable timekeeping and data retention

Package

The ISL12022MIBZ-T is supplied in an 8‑lead μSOP/MSOP package (compact 8‑pin small‑outline) and is packaged on a tape‑and‑reel (–T) for automated assembly.

Pinout

The ISL12022MIBZ-T is a 6-pin I²C real-time clock (RTC). Pin functions (typical):
- VCC: main supply input
- VBAT: backup battery input (battery-switched backup)
- GND: ground
- SDA: I²C data (bidirectional)
- SCL: I²C clock
- INT/SQW (ALARM/OUT): programmable interrupt/alarm or square‑wave output
For exact pin numbering, electrical characteristics and timing, refer to the ISL12022 datasheet.

Manufacturer

Manufacturer: Renesas Electronics Corporation (part number originally from Intersil; Intersil was acquired by Renesas in 2017).
What kind of company: Renesas is a multinational semiconductor company that designs and manufactures microcontrollers, analog and power devices, mixed-signal ICs, and system-on-chip solutions for automotive, industrial, and consumer embedded applications.

Application

Typical application areas: battery-backed timekeeping in portable and embedded systems, data logging and timestamping, consumer electronics (cameras, set-top boxes, wearables), medical devices requiring low-power RTC, industrial controls and metering, automotive electronics for time-stamping and wake-up scheduling, network equipment for event logging, and any system needing accurate, low-power I2C RTC.
