A Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory that allows for the storage of data even when power is removed. It is commonly used in various electronic devices, such as microcontrollers, computers, and consumer electronics.
Part Number: ATMLH412
Function: Two-wire Serial EEPROM, 256K (32,768 x 8)
Package: 8 Pin PDIP, SOIC, dBGA2, TSSOP Type
The ATMLH412 provides 262,144 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 32,768 words of 8 bits each. The device’s cascadable feature allows up to eight devices to share a common two-wire bus. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential.
1. Internally Organized as 32,768 x 8
2. Two-wire Serial Interface
3. Schmitt Trigger, Filtered Inputs for Noise Suppression
4. Bidirectional Data Transfer Protocol
5. 1 MHz (5.0V, 2.7V, 2.5V), and 400 kHz (1.8V) Compatibility
6. Write Protect Pin for Hardware and Software Data Protection
7. 64-byte Page Write Mode (Partial Page Writes Allowed)
8. Self-timed Write Cycle (5 ms Max)
Serial EEPROMs are commonly used to store configuration settings, calibration data, identification information, and other small amounts of non-volatile data in electronic systems. They provide a convenient and reliable solution for applications that require data storage with the ability to modify or update the stored information as needed.
