BR93G66FVT-3BGE2

Product Overview

The BR93G66FVT-3BGE2 from Rohm Semiconductor is a non-volatile EEPROM memory IC with a 4Kbit capacity and a Microwire interface. It operates from a 1.7V to 5.5V supply and supports a clock frequency of 3 MHz. The device is packaged in an 8-TSSOP-B surface-mount case with a 0.173 inch, 4.40 mm width, and is specified for an operating temperature range of -40°C to 85°C (TA).

Key Features

• Non-volatile EEPROM memory with a 4Kbit capacity and 256 x 16 organization
• Microwire interface with a 3 MHz clock frequency
• Word or page write cycle time of 5 ms
• 1.7V to 5.5V supply voltage range
• Surface-mount 8-TSSOP-B package with 0.173 inch (4.40 mm) width
• Operating temperature range of -40°C to 85°C (TA)

Applications

• Non-volatile storage of configuration data in embedded systems
• Parameter retention during power-off in microcontroller-based designs
• Memory addition for compact surface-mount designs using a Microwire interface

Design & Procurement Notes

When selecting this device, verify that the host controller supports the Microwire interface and can operate with a 3 MHz clock. The 1.7V to 5.5V supply range allows use with 1.7V to 5.5V supply rails, but host input and output compatibility should be checked. The 5 ms word or page write cycle time should be considered in firmware timing and power-loss management. The 8-TSSOP-B surface-mount package requires a matching footprint and soldering profile, and the -40°C to 85°C (TA) operating range should be confirmed against the final system environment.
