25C040T/SN Overview

Non-Volatile is its memory type. The case comes in the Tape & Reel (TR) style. It is available in 8-SOIC (0.154, 3.90mm Width) case. This chip has an 4Kb 512 x 8 size of memory on it, so a lot of data can be stored on it. This device utilizes a EEPROM format memory which is of mainstream design. With an extended designed operating temperature of 0°C~70°C TA, this device is capable of lots of demanding applications. The device is capable of handling a supply voltage of 4.5V~5.5V volts. It is recommended that the mounting type be Surface Mount. There are 8 terminations on the chip. In total, this part supports 1 functions. Memory devices such as this one are designed to be powered by 5V and should be used as such. The memory has a clock frequency rotation within 3MHz. Similar parts are frequently selected using the ic memory chip's base part number, 25C040. The memory device is enclosed in a package with an 8-pin connector. The memory device has 8 pins, which means that it has 8 memory locations, which indicates it is an 8-bit device. There is a note stating that this memory chip operates at 5V. In this chip, the Surface Mount mounting method is used, a straightforward, high-efficiency mounting method. This memory chip is rated 5mA for its nominal supply current. In spite of all the merits this chip has, it also features DATA RETENTION > 200 YEARS; 1M ENDURANCE CYCLES to level up system performance. In terms of power requirements, this memory chip uses only 5V . Data is carried and transferred to the CPU by the SPI-type serial bus this memory integrates with.
