24LC512-I/ST

24LC512-I/ST is a 512-kbit I2C serial EEPROM (64 KB) from the 24LC family. The I/ST suffix usually denotes industrial-temperature grade (and ST-style variant); verify in the datasheet for exact temp range and packaging.
Key points:
- Interface: I2C two-wire, standard and fast modes.
- Addressing: uses A0–A2 hardware pins for bus addressing; memory accessed with a 16-bit word address.
- Memory organization: 64 KB of non-volatile storage; supports random byte reads and sequential reads.
- Writes: page writes up to 128 bytes; typical write cycle a few milliseconds (tWC ~5 ms); endurance ~1,000,000 write cycles.
- Power: single supply 2.5–5.5 V; WP pin for hardware write protection.
- Package options: common 8-pin packages (SOIC, PDIP, etc.).
- Applications: configuration data, calibration data, small data logging in microcontroller-based systems.
Use it when you need persistent small data storage on I2C with moderate write endurance; always check the exact temp range, pinout, and page size in the specific datasheet you purchase.

24LC512-I/ST is a 512 Kbit (64 Kbyte) I2C serial EEPROM. Key features:
- 512 Kbit memory organized as 64 Kbytes
- I2C two-wire interface; standard (100 kHz) and fast mode (400 kHz)
- 16‑bit word addressing for full 64Kbyte address space
- Random and sequential read; current-address read supported
- Page write up to 128 bytes per operation; tWC up to ~5 ms
- Endurance: ~1,000,000 write cycles; data retention about 40 years
- Hardware write-protect (WP) input
- Industrial temperature range: typically -40°C to +85°C
- Wide supply range: about 2.7–5.5 V
- Small 8-pin packages; RoHS compliant; low power consumption with standby modes
- A0/A1/A2 pins for device addressing on the I2C bus (allows multiple devices on same bus)
Note: exact voltage and temperature specs may vary by package variant; consult the datasheet for your specific part/date code.

8-pin device. Available in standard 8-pin packages: DIP-8 and SOIC-8 (plastic). Some listings also show MSOP/TSSOP variants.

- Pin count: 8 pins (DIP-8/SO-8/TSSOP-8).
- Function: 512 Kbit I2C serial EEPROM (64K × 8) memory. Uses a 2-wire I2C interface, with A0–A2 address pins for selecting the device on the bus (up to 8 devices). Access uses a 16-bit memory address; supports random/read operations and page writes; non-volatile data storage.

Manufacturer: Microchip Technology Inc. It is a multinational semiconductor company based in Chandler, Arizona, USA, that designs and manufactures microcontrollers, memory devices (including EEPROMs like the 24LC512), analog ICs, and related components.

Typical applications of 24LC512-I/ST (I2C 512-kbit serial EEPROM) include:
- Non-volatile storage for microcontrollers (parameters, calibration constants, configuration data)
- Data logging and buffering (sensor readings, event counters)
- Firmware/boot data or update parameters
- Device identification and security keys
- Small file storage for consumer electronics, automotive instruments, industrial control, medical devices, and telecom equipment

Common equivalents (512 Kbit I2C EEPROM, 8-pin):
- ST: M24C512 (e.g., M24C512-W)
- NXP: CAT24C512
- Microchip: 24LC512 / 24AA512
- Cypress: FM24C512 (if available)
These are cross-compatible 2‑wire I2C 512‑Kbit serial EEPROMs. Pinouts and timing are generally compatible, but verify exact package/version.
