BR93G46FVT-3GE2

Product Overview

The BR93G46FVT-3GE2 from Rohm Semiconductor is a 1Kbit non-volatile EEPROM memory IC with an EEPROM memory format and a 64 x 16 organization. It uses a Microwire serial interface with a 3 MHz clock frequency and operates from 1.7V to 5.5V. The device is packaged in an 8-TSSOP-B surface-mount package, corresponding to an 8-TSSOP case with a 0.173 inch, 4.40mm width, and has an ambient operating temperature range of -40°C to 85°C.

Key Features

• 1Kbit EEPROM memory capacity with a 64 x 16 organization for serial data storage.
• Microwire serial interface supporting a 3 MHz clock frequency.
• Wide supply voltage range from 1.7V to 5.5V.
• 5ms word/page write cycle time.
• 8-TSSOP-B surface-mount package with 0.173 inch, 4.40mm width.
• Operating temperature range of -40°C to 85°C (TA).
• Surface-mount mounting type for PCB assembly.

Applications

• Nonvolatile configuration storage for embedded controllers.
• Serial parameter retention in compact electronic assemblies.
• Small data storage tasks in systems using a Microwire serial interface.

Design & Procurement Notes

When selecting this device, confirm that the host controller supports Microwire communication and can operate within the 1.7V to 5.5V supply range. The 64 x 16 memory organization and 3 MHz clock frequency should match the system address and timing plan, while the 5ms write cycle time should be considered for update latency. The 8-TSSOP-B footprint and surface-mount mounting style affect PCB layout, and the -40°C to 85°C ambient temperature range should be evaluated against the intended operating environment. Verify that the package dimensions and supply voltage compatibility align with the board design and assembly process.
