    Products Detail

    24LC21T/SN Overview


    Non-Volatile is the type of memory it has. There is a Tape & Reel (TR) case available. The 8-SOIC (0.154, 3.90mm Width) case contains it. The chip has an 1Kb 128 x 8 memory. This device uses a EEPROM-format memory, which is of mainstream design. A wide operating temperature range makes this device ideal for a variety of demanding applications. A voltage of 2.5V~5.5V can be supplied to memory ics. Its recommended mounting type is Surface Mount. The chip has 8 terminations. For a comprehensive working procedure, this part supports as many as 1 functions. In order to operate this memory device, it must be supplied with 3V of power. It is important to note that the memory has a clock frequency rotation within the range of 400kHz. Similar parts are frequently selected using 24LC21, the device's base part number. The memory device is enclosed in a package with an 8-pin connector. There are 8 pins on this memory device, which indicates it has 8 memory locations in it. In this chip, Surface Mount mounting is used, a straightforward, high-efficiency mounting method. In terms of its nominal supply current, this memory component is rated at 3mA. Despite all its merits, this chip also features 2-WIRE SERIAL INTERFACE; DATA RETENTION > 200 YEARS; 1000000 ERASE/WRITE CYCLES GUARANTEED to boost system performance. When it comes to power supplies, this memory chip only requires 3/5V . Data is carried and transferred to the CPU by the I2C-type serial bus this memory integrates with.
