25LC512 in 25LCxx / AT25 SPI EEPROM Family
The 25LC512 is a 512-Kbit serial Electrically Erasable PROM (EEPROM) family primarily manufactured by Microchip Technology. Operating over a wide voltage range, these devices utilize the Serial Peripheral Interface (SPI) bus for high-speed data transfer. They are engineered for non-volatile storage in space-constrained embedded systems where byte-level flexibility and high endurance are critical for maintaining configuration data, calibration tables, and user logs without the page-erase overhead typical of Flash memory.
Variants in This Sub-Family
Variants within the 25LC512 series primarily differ by packaging type and temperature rating. Common packages include 8-lead PDIP, SOIC, and SOIJ, as well as space-saving TSSOP and DFN options. Temperature grades range from industrial (-40C to +85C) to extended/automotive (-40C to +125C). Certain suffixes also denote tape and reel packaging versus tube delivery, or lead-free (Pb-free) finish compliance for RoHS regulatory requirements.
