BQ3285ES

Overview

The BQ3285ES is a Real-Time Clock (RTC) IC manufactured by Texas Instruments, featuring an integrated 242x8 Non-Volatile Static RAM (NVSRAM). It utilizes a multiplexed bus interface and supports date formats of YY-MM-DD-dd with HH:MM:SS timekeeping in 24-hour mode. The device operates within a supply voltage range of 4.5 V to 5.5 V and functions at temperatures between 0°C and +70°C. Packaged in a 24-pin SOIC, it includes alarm and wake-up capabilities.

Feature Summary

Integrated 242-byte NVSRAM for data retention
Multiplexed parallel bus interface
Alarm and wake-up functionality
Calendar and timer interrupt features

Applications

Systems requiring non-volatile timekeeping and data storage
Industrial equipment with standard temperature requirements
Embedded controllers needing calendar and alarm interrupts

Procurement Notes

This component is designated as End-of-Life (EOL) by Texas Instruments. Production discontinuation notifications have been issued, indicating that the manufacturer will cease production. Verification of current availability should focus on distributor surplus stock or authorized secondary market sources rather than direct factory orders.

Selection Notes

Designers must account for the EOL status when selecting this part. The BQ3285ES requires a 4.5 V to 5.5 V power supply and a 24-pin SOIC footprint. Alternative solutions should be evaluated if long-term supply stability is required, as original manufacturing support is no longer active.

Part Context

The BQ3285ES belongs to the BQ3285E series of real-time clocks. It combines RTC functionality with significant onboard memory capacity compared to basic RTCs, allowing for system state preservation alongside timekeeping in a single package.
