BR25L320F-WE2

Memory IC Overview

The BR25L320F-WE2 is a serial EEPROM from the BR25Lxxx-W series manufactured by ROHM Semiconductor. It features an SPI bus interface with a storage capacity of 32 kbit organized as 4K x 8 bits. The device operates on a single power source ranging from 1.8V to 5.5V and supports a maximum clock frequency of 5MHz. It offers data retention for 40 years and endurance up to 1,000,000 rewrite cycles. The component is housed in an SOP-8 package and functions within an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports page write mode for efficient initial value writing at factory shipment
• Includes wait function via HOLD terminal to temporarily suspend command communications
• Features write mistake prevention mechanisms including write prohibition at power-on and low voltage protection
• Allows memory arrays to be set as read-only areas via program commands

Memory IC Applications

• Battery-powered devices requiring low current consumption
• Systems needing non-volatile data storage with high-speed SPI access
• Applications requiring configurable write-protection blocks

Memory IC Procurement Notes

Verify the specific suffix 'F' against official documentation to confirm package type and material specifications. Confirm supply status as the BR25L series may have designated 'Not Recommended for New Designs' variants. Ensure compatibility with required voltage levels and interface timing constraints before procurement.

Memory IC Selection Notes

Select this component for applications requiring 32 kbit SPI EEPROM with wide voltage operation. Consider the SOP-8 package dimensions for PCB layout. Evaluate the need for hardware write protection via the WP pin and the availability of block protection settings for security requirements.

Memory IC Part Context

This part belongs to the BR25Lxxx-W series of standard SPI Serial EEPROMs produced by ROHM Semiconductor. The series includes densities from 1K to 64K bits. The BR25L320F-WE2 specifically represents the 32K bit variant in the SOP-8 package format, designed for general-purpose non-volatile memory storage.
