24VL014T/SN

Memory IC Overview

The Microchip Technology 24VL014 is a 1 Kbit Serial Electrically Erasable PROM organized as a single block of 128 x 8-bit memory. It operates on a single supply ranging from 1.5V to 3.6V with a maximum clock frequency of 400 kHz, or 100 kHz when VCC is below 1.8V. The device features low-power CMOS technology with a maximum active current of 400 μA and standby current of 1 μA. It supports I2C-compatible 2-wire serial interface communication.

Memory IC Feature Summary

• Hardware write protection for the entire array via the WP pin
• Page write buffer capability for up to 16 bytes
• Schmitt trigger inputs for noise suppression
• Output slope control to eliminate ground bounce

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• I2C bus expansion using cascaded devices
• Battery-powered applications due to low standby current
• Industrial environments benefiting from Schmitt trigger noise immunity

Memory IC Procurement Notes

Verify the specific package type (PDIP, SOIC, TSSOP, MSOP, TDFN, or SOT-23) matches your board design requirements. Confirm that the voltage range of 1.5V to 3.6V aligns with your system's power supply. Ensure the I2C pull-up resistor values are appropriate for the selected clock speed and bus capacitance. Check for RoHS compliance if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM capacity is sufficient for the application. Choose based on the required operating voltage range and available package styles. Consider the SOT-23 package only if four devices are needed on the bus, as it lacks the A2 address pin. Verify that the hardware write protection feature meets security requirements for the memory array.

Memory IC Part Context

The 24VL014 belongs to Microchip's 24-series of serial EEPROMs. It provides a compact solution for storing configuration data or small amounts of user information in space-constrained designs. The device is compatible with standard I2C protocols, allowing easy integration with microcontrollers and other digital controllers supporting the 2-wire serial interface.

Memory IC Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers within the 24-series family. Ensure any replacement maintains compatibility with the 1.5V to 3.6V operating range and I2C interface specifications.
