BU9891GUL-WE2 Overview

As far as its memory type goes, it falls into the Non-Volatile category. You can get memory ics in a Tape & Reel (TR) case. 6-UFBGA, CSPBGA case encloses it. There is 4Kb 256 x 16 of memory on the chip. The device uses a mainstream EEPROM-format memory. Suitable for use in a wide range of demanding applications, this device offers an extended operating temperature range of -40°C~85°C TA. There is a voltage range of 1.7V~5.5V for the supply voltage. It is recommended that the mounting type be Surface Mount. There are 6 terminations on the chip. There are 1 functions supported by this part as part of the comprehensive working process. It has a clock frequency of 2MHz. When choosing similar parts, BU9891 is frequently referred to as the device's base part number. It is worth noting that this memory device has 6 pins, which indicates it has 6 memory locations. As a result of the Surface Mount mounting configuration, this chip is designed to be straightforward, high-efficiency, and easy to install. As for the power supply, this memory chip only needs 1.8/5V . Integrated into this memory is a 3-WIRE-type serial bus that facilitates data transmission to the CPU. The device is able to run from a max supply current of 0.003mA , so it can be used in any environment.
