25LC256T‑E/SN is a high‑reliability 256‑Kbit serial EEPROM memory chip manufactured by Microchip Technology, organized as 32K × 8‑bit storage and communicating through a standard 4‑wire SPI serial interface. Packaged in the compact surface‑mount 8‑pin SOIC housing with tape‑and‑reel delivery, this low‑power CMOS memory device operates from 2.5 V to 5.5 V supply voltage, supports a maximum 10 MHz clock speed, delivers one‑million erase‑write cycle endurance and over 200‑year non‑volatile data retention, and performs stably over the extended industrial temperature range of ‑40 °C to 125 °C for storing configuration parameters, calibration data and user log information in embedded electronic systems.
Key Features
● 256‑Kbit non‑volatile storage capacity with 32768×8‑bit memory organization for flexible byte‑level and 64‑byte page‑oriented write operations.
● Standard SPI serial communication interface supporting up to 10 MHz maximum clock frequency and sequential‑read mode for fast bulk data fetching.
● Wide 2.5 V‑5.5 V operating voltage range, compatible with both 3.3‑volt and 5‑volt microcontroller power domains.
● Integrated multi‑level hardware protection mechanisms including write‑protect pin, write‑enable latch and power‑on/power‑off data safeguard circuits to avoid accidental data corruption.
● Low‑power consumption with 6 mA typical active read current and 5 µA standby current, well suited for battery‑powered equipment.
Applications
25LC256T‑E/SN is widely adopted for storing system configuration files, sensor calibration coefficients, event log records and user‑setting parameters within industrial control modules, smart home sensor hardware, wearable battery‑operated gadgets, automotive accessory electronics, handheld measurement instruments, consumer home appliances, PLC peripheral boards and embedded IoT sensor nodes that require reliable, low‑cost non‑volatile data storage without high‑speed mass‑memory demands.
FAQ
Q: What function does the WP pin serve?
A: The write‑protect pin locks part or all memory blocks against accidental write‑in operations for critical data protection.
Q: What is the maximum time required for a page write operation?
A: The self‑timed erase‑write cycle finishes within 5 ms maximum after sending valid write commands.
Alternative EEPROM Models
1. 25LC256‑I/SN: Function‑identical 256Kbit SPI EEPROM in SOIC‑8 package with industrial temperature rating, a non‑tape version alternative for small‑batch assembly projects.
2. AT25256B‑SSHL‑T: Atmel‑manufactured 256‑Kbit SPI serial memory with matching capacity and interface, serving as a cross‑brand drop‑in functional replacement.
3. 25LC128T‑E/SN: 128‑Kbit SPI EEPROM with identical package and electrical features, a cost‑effective downgrade choice when smaller storage space satisfies project requirements.
