BR93G46FVT-3BGE2

Product Overview

The Rohm Semiconductor BR93G46FVT-3BGE2 is a 1Kbit non-volatile EEPROM memory IC for small-capacity data retention in embedded and electronic systems. It uses a Microwire serial interface and is specified for operation with a 3 MHz clock, with a 64 x 16 memory organization. The device operates from a 1.7V to 5.5V supply and is offered in a surface-mount 8-TSSOP package with a 4.40mm body width. Its rated operating temperature range is -40°C to 85°C.

Key Features

• 1Kbit EEPROM memory capacity with non-volatile data retention
• 64 x 16 memory organization
• Microwire serial memory interface
• 3 MHz clock frequency
• 5ms write cycle time for word or page operations
• 1.7V to 5.5V supply voltage range
• Operating temperature range of -40°C to 85°C
• Surface-mount 8-TSSOP package, 0.173in (4.40mm) width
• 8-TSSOP-B package designation

Applications

• Embedded systems that need to retain small configuration tables after power removal
• Electronic devices storing calibration constants, identifiers, or limited parameter sets
• Access or identification modules requiring non-volatile storage of serial numbers or small configuration records
• Portable or space-constrained electronics where a compact non-volatile memory footprint is needed

Design & Procurement Notes

When selecting the BR93G46FVT-3BGE2, confirm that the host controller supports a Microwire serial interface and that timing is compatible with the 3 MHz clock specification. The 1.7V to 5.5V supply range and -40°C to 85°C operating range should be matched to the system power and ambient conditions. The 5ms write cycle time should be accounted for in firmware when updating word or page data. PCB layout should use a footprint compatible with the surface-mount 8-TSSOP package, 4.40mm width, and 8-TSSOP-B designation.
