BR93L66FJ-WE2 Product Details

BR93L66FJ-WE2 Overview


As far as memory types are concerned, Non-Volatile is considered to be its memory type. In addition, memory ics is available in a Tape & Reel (TR) case as well. In the case of 8-SOIC (0.154, 3.90mm Width), it is embedded within the case. A memory chip with a capacity of 4Kb 256 x 16 is used on this device. There is a mainstream memory format used by this device, which is called EEPROM-format memory. This device has an extended operating temperature range of -40°C~85°C TA, so it's perfect for a wide range of demanding applications. It is capable of handling a voltage supply of 1.8V~5.5V. As far as the mounting type is concerned, Surface Mount is recommended. On the chip, there are 8 terminations that are planted. The part supports at least 1 functions to ensure a comprehensive working process. In order to function properly, this ic memory chip should be powered by a voltage of 2.5V. In the memory, there is a clock frequency rotation that ranges 2MHz. The memory device has an 8-pin package, which encloses it in a small package. I have noticed that the memory device has 8 pins, which indicates that it has 8 locations in the memory. According to the datasheet, this memory chip operates at an operating voltage of 5V. The MICROWIRE-type serial bus this memory integrates with is helpful for transferring data to the CPU. As far as the supply current is concerned, it can be operated with a maximum of 0.0015mA of current
