BR93G86FV-3AGTE2

Memory IC Overview

The BR93G86FV-3AGTE2 is a 16-kbit Microwire bus EEPROM manufactured by ROHM Semiconductor, organized as 1024 words by 16 bits. It operates within a supply voltage range of 1.7 V to 5.5 V and supports a maximum clock frequency of 3 MHz. The device utilizes an SSOP-B-8 surface-mount package and functions across an industrial temperature range from -40°C to +85°C. Key electrical characteristics include a maximum active read current of 3 mA and a standby current of 2 µA. Data retention is specified for up to 40 years.

Memory IC Feature Summary

• Supports high-speed serial communication via a 3-line Microwire interface with chip select, serial clock, and shared data input/output lines.
• Includes write protection mechanisms such as power-on write prohibition, command-code-based write inhibition, and low-voltage prevention features.
• Features address auto-increment during read operations and automatic program cycle deletion and termination.

Memory IC Applications

• Non-volatile data storage in automotive electronic control units
• Configuration memory for industrial sensor modules
• Parameter storage in consumer electronics devices

Memory IC Procurement Notes

Verify the component status carefully before integration, as this part is classified as Not Recommended for New Designs (NRND). Confirm that existing inventory levels meet project requirements, since future production may be limited or discontinued. Ensure compatibility with current design constraints given the end-of-life designation.

Memory IC Selection Notes

Select this component only if maintaining compatibility with existing designs or sourcing from remaining stock is necessary. Evaluate alternative parts from the same family if new development is planned, considering the NRND status. Verify package dimensions and pinout compatibility against the specific SSOP-B-8 footprint required by the target PCB layout.

Memory IC Part Context

This EEPROM belongs to the BR93G series, which offers various densities ranging from 1-kbit to 16-kbit. The series shares common interface protocols and physical package options, including SOP, SSOP, and TSSOP variants. The BR93G86 specifically denotes the 16-kbit capacity within this lineup, designed for applications requiring reliable non-volatile storage with simple serial connectivity.
