onsemi Memory NV25040DWHFT3G

The NV25040DWHFT3G is a 4 Kbit EEPROM memory device from Lingto Electronic Limited, designed for automotive applications with an operating temperature range of -40¬8C to +150¬8C. It is organized as 512x8 bits and supports the Serial Peripheral Interface (SPI) protocol with a maximum clock frequency of 10 MHz. The device features a 16-byte page write buffer, allowing for efficient data writing. This EEPROM includes both hardware and software write protection mechanisms, including block write protection options for 1/4, 1/2, or the entire memory array. It also incorporates on-chip Error Correction Code (ECC) to enhance data reliability by correcting single-bit errors. The NV25040DWHFT3G operates with a supply voltage range of 2.5 V to 5.5 V and has a data retention capability of up to 200 years. The device is available in both SOIC and TSSOP 8-lead packages and is compliant with RoHS standards, being Pb-free and halogen-free. Its endurance ratings indicate it can withstand up to 600,000 write cycles at 125¬8C and 300,000 cycles at 150¬8C, making it suitable for high-reliability applications.
