Description
Introduction (concise)
- 24LC515-I/SM is Microchip’s 512‑Kbit I2C serial EEPROM (nonvolatile memory) in an 8‑pin surface‑mount package.
- Organization: 64 Kbytes of storage, accessed via a two‑wire I2C interface (SCL, SDA).
- Addressing: Uses two‑byte memory addressing with hardware address pins A0–A2 to allow up to eight devices on the bus.
- Variant: “-I” denotes Industrial temperature range; “/SM” indicates surface‑mount packaging.
- Voltage and temp: Typically 2.7–5.5 V supply; −40°C to +85°C operating range.
- Performance and endurance: Typical write cycle ~a few milliseconds; endurance ~1,000,000 write cycles; data retention on the order of decades.
- Features: Random and sequential read, page write capability, hardware write‑protect (WP) option.
- Applications: Data logging, configuration storage, event buffering in embedded systems.
Note: Always confirm exact page size and timing from the specific datasheet revision.
