Microchip AT24C01D-SSHM-B: A Compact 1K I²C Serial EEPROM Memory Solution
The Microchip AT24C01D-SSHM-B is a 1-Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) device organized as 128 x 8 bits. It is designed for low-power and general-purpose applications where reliable non-volatile data storage is required. This memory chip utilizes the ubiquitous I²C (Inter-Integrated Circuit) serial protocol for communication, making it an ideal choice for interfacing with microcontrollers and processors in space-constrained designs.
A key feature of this EEPROM is its two-wire serial interface, which significantly reduces the number of I/O pins required for communication compared to parallel memory chips. This allows for simpler PCB layouts and lower overall system cost. The device supports a 400 kHz clock frequency, enabling efficient data transfer rates suitable for a wide range of applications, from consumer electronics to industrial systems.
The AT24C01D-SSHM-B operates over a broad voltage range (1.7V to 5.5V) and boasts extremely low active and standby current consumption, which is critical for battery-powered and portable devices. It also features a page write buffer of up to 8 bytes and hardware data protection where the entire memory array can be write-protected by tying the WC pin to VCC. This ensures data integrity by preventing inadvertent writes.
Housed in a space-saving 8-lead SOIC package, this EEPROM is built for reliability and endurance, supporting 1 million write cycles and a data retention period of 100 years. Its industrial temperature range ensures stable performance even in harsh environments.
ICGOOODFIND: The Microchip AT24C01D-SSHM-B is a highly efficient and reliable 1K serial EEPROM, offering an optimal blend of low power consumption, compact packaging, and robust data retention. Its compatibility with the standard I²C bus makes it a versatile and easy-to-integrate memory solution for modern electronic designs.
