Product details
Overview
24LC16SC/S15K from Microchip Technology is a 16 Kbit I²C-compatible serial EEPROM organized as 2,048 × 8 bits, operating from 2.5V to 5.5V, with 16-byte page write capability, 400 kHz maximum clock frequency, and 1 million write/erase cycles endurance. It is used for nonvolatile storage of configuration data in embedded systems such as industrial controllers and consumer electronics.
For engineers reviewing the 24LC16SC/S15K datasheet, 24LC16SC/S15K pinout, 24LC16SC/S15K application, or 24LC16SC/S15K equivalent, key selection criteria include I²C bus compatibility, SOIC-8 packaging, write-protect functionality, page-write timing (5 ms), and industrial temperature grade (–40°C to +85°C).
Technical Context
This device implements a standard two-wire I²C interface with slave address support (7-bit addressing), ACK/NACK handshaking, and sequential read/write operations. It features hardware write protection via the WP pin and supports both byte-write and page-write modes.
The memory array is divided into 128 pages of 16 bytes each, enabling efficient bulk writes within a single page boundary. Internal address auto-increment simplifies multi-byte transfers without external address management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Kbit (2,048 × 8 bits) - provides sufficient space for firmware parameters, calibration data, or user settings in compact embedded designs. |
| Interface | I²C (Two-wire serial) - enables simple, low-pin-count connection to microcontrollers with minimal PCB routing overhead. |
| VCC Range | 2.5V to 5.5V - ensures interoperability with legacy 5V logic and modern 3.3V systems without level-shifting. |
| Page Size | 16 bytes - allows up to 16 bytes to be written in a single operation, reducing bus transactions and improving write efficiency. |
| Write Cycle Time | 5 ms max per page - defines worst-case latency for persistent storage updates; critical for real-time logging or state-save operations. |
| Endurance | 1,000,000 write/erase cycles - supports long-term reliability in applications requiring frequent parameter updates, such as energy metering or sensor calibration. |
| Temperature Grade | Industrial (–40°C to +85°C) - validated for stable operation across extended ambient conditions in factory automation and outdoor equipment. |
Pinout & Package
24LC16SC/S15K is housed in an 8-lead SOIC package (150 mil width), with gull-wing leads and RoHS-compliant Pb-free plating. The package meets JEDEC MS-012 standards and is suitable for reflow soldering per Microchip's recommended profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Address Input | LSB of 7-bit slave address; tied high/low to select one of eight possible I²C addresses on shared bus. |
| A1 | Address Input | Second LSB of slave address; enables multiple devices on same I²C bus with unique addressing. |
| A2 | Address Input | MSB of slave address; completes 3-bit hardware address selection (A2–A0). |
| VSS | Ground | Reference return path for all internal circuitry and I/O signals. |
| SDA | Serial Data | Open-drain bidirectional I²C data line; requires external pull-up resistor (typically 2.2–10 kΩ). |
| SCL | Serial Clock | Input-only I²C clock line; synchronizes all data transfers between master and slave. |
| WP | Write Protect | Active-high input that disables all write operations when asserted; enables hardware-level data integrity control. |
| VCC | Power Supply | Primary supply voltage input (2.5–5.5V); powers EEPROM core and I/O buffers. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware Write Protection | WP pin provides immediate, pin-level disable of all write commands - prevents accidental overwrites during power transitions or firmware faults. |
| Page Write Capability | 16-byte page buffer enables burst writes within a single page, reducing I²C transaction count and improving system-level throughput. |
| Low-Voltage Operation | 2.5V minimum VCC supports integration with 3.3V microcontrollers and battery-powered systems without voltage translation. |
| High Endurance | 1 million write cycles exceeds typical requirements for configuration storage, enabling robust field deployment in industrial environments. |
| Industrial Temperature Range | –40°C to +85°C operation verified per AEC-Q100 stress testing - suitable for automotive body electronics and factory floor equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24LC16B-I/SN | Same density, page size, and I²C interface; differs only in package marking (SN = standard SOIC vs. S15K = 150-mil SOIC variant) and minor date-code formatting. | No functional difference; identical electrical and timing behavior across industrial temperature range. | Select 24LC16B-I/SN if standard SOIC-8 footprint and broad distributor availability are prioritized over specific tape-and-reel labeling conventions. |
| 24AA16-I/SN | Wider VCC range (1.8–5.5V); otherwise identical density, page size, and I²C timing; shares same SOIC-8 package. | Enables use in 1.8V logic domains (e.g., ultra-low-power MCUs) where 24LC16SC/S15K cannot operate below 2.5V. | Choose 24AA16-I/SN for battery-powered or mixed-voltage systems requiring sub-2.5V operation; otherwise 24LC16SC/S15K offers optimal cost/performance for 3.3V/5V designs. |
Compared with 24LC16B-I/SN, the 24LC16SC/S15K offers identical functionality in a functionally equivalent package, while 24AA16-I/SN extends voltage flexibility at no penalty to endurance or timing - making it preferable for next-generation low-power platforms.

Does the 24LC16SC/S15K include hardware write protection?
Yes, the 24LC16SC/S15K includes a dedicated WP (Write Protect) pin. When driven high, this pin disables all write operations-including byte-write, page-write, and write-enable instructions-providing deterministic hardware-level data security independent of firmware control.
What package type is used for the 24LC16SC/S15K?
The 24LC16SC/S15K uses an 8-lead SOIC package with 150-mil body width (standard JEDEC MS-012 outline). It features gull-wing leads, RoHS-compliant Pb-free plating, and is qualified for reflow soldering per IPC/JEDEC J-STD-020.
Is the 24LC16SC/S15K rated for industrial temperature operation?
Yes, the 24LC16SC/S15K is specified for industrial temperature operation from –40°C to +85°C. This rating is validated through extended temperature cycling, high-temperature operating life (HTOL), and data retention testing per Microchip's quality protocol.
How many write/erase cycles does the 24LC16SC/S15K guarantee?
The 24LC16SC/S15K guarantees a minimum of 1,000,000 write/erase cycles per memory location. This endurance specification is measured per JEDEC Standard No. 22-A117 and applies across the full industrial temperature range and VCC operating window.
