BU9890GUL-WE2 Overview

In this case, the memory type of the device can be classified as Non-Volatile. In addition, memory ics is available in a Tape & Reel (TR) case as well. In the case of 6-UFBGA, CSPBGA, it is embedded within the case. There is an 32Kb 4K x 8 memory capacity on the chip. This device uses a EEPROM-format memory, which is of mainstream design. Featuring an extended operating temperature range of -40°C~85°C TA, this device allows it to be used in a variety of demanding applications. A voltage of 1.7V~3.6V is possible to be applied to the supply. It is recommended to mount it in the Surface Mount mounting type. The chip is terminated with 6 terminations. There is a clock frequency rotation of the memory within a 400kHz range. When choosing similar parts, BU9890 is frequently referred to as the device's base part number. This memory device is enclosed in a 6-pin package. In this chip, the Surface Mount mounting method is used, a straightforward, high-efficiency mounting method. The power supply needed for this memory chip is only 1.8/3.3V . The I2C-type serial bus this memory integrates with is helpful for transferring data to the CPU. In order for it to operate properly, memory ics requires a maximum supply current of 0.0041mA .
