BR93G86F-3GTE2

Product Overview

The BR93G86F-3GTE2 from Rohm Semiconductor is a non-volatile EEPROM memory IC with 16Kbit capacity and a Microwire serial interface. It supports a 3 MHz clock frequency and has a memory organization of 2K x 8 or 1K x 16. The device operates from a 1.7V to 5.5V supply and is specified for an ambient temperature range of -40°C to 85°C (TA). The package is a surface-mount 8-SOP, with an 8-SOIC case width of 4.40 mm (0.173 in).

Key Features

• 16Kbit non-volatile EEPROM memory capacity.
• Microwire serial interface with 3 MHz clock frequency support.
• Memory organization: 2K x 8 or 1K x 16.
• Word/page write cycle time of 5 ms.
• 1.7V to 5.5V supply voltage range.
• Operating temperature range of -40°C to 85°C (TA).
• Surface-mount 8-SOP package; 8-SOIC case, 4.40 mm (0.173 in) width.

Applications

• Non-volatile storage of configuration parameters in embedded systems.
• Retention of calibration values that must remain available after power removal.
• Storage of device identity or serial-number information for embedded hardware.
• Small-data retention or status-flag storage in Microwire-based embedded systems.

Design & Procurement Notes

When selecting the BR93G86F-3GTE2 for a design, verify that the host interface can operate with Microwire at 3 MHz and that the required data width matches either the 2K x 8 or 1K x 16 organization. The 5 ms word/page write cycle time should be included in firmware timing and power-loss sequencing. The 1.7V to 5.5V supply range and -40°C to 85°C (TA) operating range should be checked against the system rail and ambient conditions. The surface-mount 8-SOP package and 4.40 mm (0.173 in) case width should be considered for PCB layout and mounting considerations.
