Product Details
PT7C4337WEX – Diodes Incorporated Low-Power I2C Real-Time Clock / Calendar IC
PT7C4337WEX is a Diodes Incorporated low-power serial real-time clock and calendar IC designed for timekeeping, date tracking, alarm generation and square-wave output functions in embedded electronic systems. With I2C / 2-wire serial interface, external 32.768kHz crystal support, 12-hour and 24-hour time format, seconds, minutes, hours, day, date, month and year counters, two programmable alarms, programmable square-wave output, 1.8V to 5.5V operating range and 8-SOIC package, it is suitable for control boards, security devices, consumer electronics, industrial modules, data logging systems and general timekeeping designs.
Engineering note: Confirm 32.768kHz crystal load capacitance, I2C pull-up resistor values, alarm interrupt routing, square-wave output setting, timekeeping voltage range and the latest Diodes Incorporated datasheet before production approval.
Component Overview
PT7C4337WEX belongs to the Diodes Incorporated PT7C4337 family of low-power I2C real-time clock devices. It provides clock and calendar information through a 2-wire serial interface and supports automatic adjustment for months with fewer than 31 days, including leap-year correction. The device is useful when a microcontroller, processor or embedded system needs reliable time and date tracking without using many host pins.
Circuit Function & Design Role
Maintains seconds, minutes, hours, date, day, month and year information for embedded systems.
Uses a 2-wire serial bus to reduce host pin count while providing RTC register access.
Supports programmable alarm functions for time-based wake-up, event timing or system notification.
Provides a programmable square-wave output that can be used for timing or reference clock functions.

TomatoElec Quality & Supply Notes
As an in-stock independent distributor and electronic components supplier, TomatoElec supports PT7C4337WEX sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For RTC and timing ICs, correct manufacturer, package code, reel suffix, date code, moisture handling and original sourcing are important because the device affects timekeeping accuracy, firmware compatibility and long-term system reliability.
- Original component sourcing: support sourcing of original Diodes Incorporated RTC and timing IC products.
- Inventory support: help confirm available stock, package condition, date code and shipment schedule.
- Package verification: confirm W / 8-SOIC package and X tape-and-reel ordering information before shipment.
- BOM matching: verify interface, supply range, timekeeping current, alarm functions, package and temperature range before approving any substitute.
Replacement & BOM Matching Guidance
PT7C4337WEX should not be replaced only by matching "I2C RTC." Engineers should compare register map, alarm behavior, oscillator circuit, square-wave output, supply voltage, timekeeping current, package footprint and firmware compatibility.
