25LC040T/SN Description

Short technical summary and product information.

The Microchip Technology 25LC040T/SN is a 4 Kbit serial Electrically Erasable PROM (EEPROM) that communicates via a Serial Peripheral Interface (SPI) bus. This device offers a memory organization of 512 x 8 bits and supports a maximum clock frequency of 2 MHz.

 

Designed for flexibility, the 25LC040T/SN operates within a voltage range of 2.5V to 5.5V. Key electrical characteristics include a typical write current of 3 mA, a typical read current of 500 μA, and a low standby current of 500 nA. The write cycle time is a maximum of 5 ms. The EEPROM array is organized into pages, with each page containing 16 bytes.

 

This component features built-in write protection mechanisms, including power on/off data protection circuitry, a write enable latch, and a write-protect pin. It also supports sequential read operations. The device is rated for an operating temperature range of 0°C to 70°C (TA) and comes in an 8-SOIC package suitable for surface mounting.

 

With high reliability features such as an endurance of 1M cycles and data retention exceeding 200 years, the 25LC040T/SN is suitable for various embedded applications requiring non-volatile data storage.
