BR93G46FJ-3GTE2

Product Overview

The Rohm Semiconductor BR93G46FJ-3GTE2 is a non-volatile EEPROM memory IC with a 1Kbit memory size organized as 64 x 16. It uses a Microwire memory interface and supports a clock frequency of 3 MHz. The device operates from a supply voltage range of 1.7V to 5.5V and is specified for an ambient operating temperature range of -40°C to 85°C (TA). The device package is 8-SOP-J, with surface-mount mounting and an 8-SOIC (0.154", 3.90mm Width) package/case. The write cycle time for word or page operations is 5ms.

Design & Procurement Notes

When selecting this device, verify that the host controller supports a Microwire interface and that the system clock does not exceed 3 MHz. Confirm that the available supply voltage remains within 1.7V to 5.5V and that ambient conditions stay within -40°C to 85°C (TA). The 1Kbit capacity and 64 x 16 organization define the available data structure; account for the 5ms word/page write cycle time in update timing. The 8-SOP-J surface-mount package with 8-SOIC (0.154", 3.90mm Width) dimensions should be checked against the PCB footprint and assembly process.
