概要

Description

24LC1025-I/P is Microchip’s 1-Mbit I2C serial EEPROM in an 8-pin package (Industrial temperature range, Plastic package). It provides non-volatile storage for microcontrollers with random and sequential access.
Key points:
- Capacity and organization: 1,048,576 bits ≈ 128 kBytes of storage.
- Interface: I2C two-wire bus (SCL/SDA); supports standard and fast I2C modes.
- Addressing: Uses 16-bit memory addressing to access the full array.
- Features: Page write and sequential read support; hardware write-protect (WP) pin to guard memory; low-power operation.
- Packaging: Available in common 8-pin packages; the –I/P suffix denotes Industrial temperature range and Plastic packaging.
Typical uses: storing configuration data, calibration parameters, logs, or any non-volatile data that must survive power cycles.
For exact electrical specs, timing, pinout, and device addressing details, consult the Microchip 24LC1025 datasheet.

Features

Here are concise features of 24LC1025-I/P (Industrial temp, Plastic package):
- 1 Kbyte (1024 × 8) I2C Serial EEPROM
- I2C two-wire interface; standard mode (100 kHz) and fast mode (400 kHz)
- 128-byte page write capability (writes within a page; wrap at page end)
- A0–A2 hardware address pins for multiple devices on the same bus (base address 0x50–0x57)
- WP (Write Protect) pin for hardware protection of memory
- Endurance: ~1,000,000 write cycles; data retention ~40 years
- Write cycle time: about ~5 ms; device supports ACK polling during write
- Industrial temperature range: -40°C to +85°C
- 8-pin Plastic package (I/P suffix indicates Industrial temp, Plastic package)
- Low-power operation with standby/idle modes
Note: specifics like exact voltage range and access times are per datasheet; ensure compatibility with your system.
