    Products Detail

    24LC21A/P Overview


    In this case, the memory type of the device can be classified as Non-Volatile. Case Tube is available. An embedded 8-DIP (0.300, 7.62mm) case surrounds memory ics. It is estimated that the memory size on the chip is 1Kb 128 x 8. As with most mainstream devices, this one uses EEPROM-format memory. Due to its wide temperature range of 0°C~70°C TA, this device is well suited to a wide range of applications that require high performance. With 2.5V~5.5V as the supply voltage, it is capable of handling memory ics. It is recommended to mount it in the Through Hole mounting type. It is planted on the chip with 8 terminations. It supports up to 1 functions for comprehensive operation. There is a requirement for 3V to be supplied to this ic memory chip in order to operate. In order to operate effectively, the memory rotates at a clock frequency within a range of 400kHz. A device's base part number, 24LC21A, is often used in order to identify similar components. The ic memory chip comes in a package with 8 pins that allows it to be connected to a computer. The memory device has a total of 8 pins, thus indicating that it has a total of 8 memory locations. This chip uses Through Hole mounting, a straightforward, high-efficiency method of mounting. It is rated 3mA for its nominal supply current when it comes to the memory component. In terms of power requirements, this memory chip uses only 3/5V . It is helpful to carry data to the CPU using the I2C-type serial bus that this memory integrates with.
