Overview
The AT24C02D-MAHM-T is a 2Kbit serial EEPROM (Electrically Erasable Programmable Read-Only Memory) chip manufactured by Microchip Technology. This device is designed for applications requiring non-volatile memory storage and features a 256 x 8 organization, meaning it can store 256 bytes of data, each byte consisting of 8 bits. The AT24C02D-MAHM-T is compatible with the I2C (Inter-Integrated Circuit) interface and supports clock frequencies up to 1 MHz. It is packaged in an 8-pin UDFN (Ultra Dual Flat No-Lead) package, making it suitable for space-constrained designs.
