Product details
Overview
AT24C04N-10SC from Microchip Technology (formerly Atmel) is a 4-kbit (512 × 8) I²C-compatible serial EEPROM with 2.7V to 5.5V supply operation, 100 kHz clock frequency at 2.7V, write-protect pin for hardware data protection, and 16-byte page write capability. It serves as nonvolatile configuration storage in embedded microcontroller systems requiring low-power, space-constrained memory.
For engineers reviewing the AT24C04N-10SC datasheet, AT24C04N-10SC pinout, AT24C04N-10SC application, or AT24C04N-10SC equivalent, key selection factors include its 2.7V–5.5V operating range, 16-byte page write mode, WP pin functionality, endurance of 1 million write cycles, and JEDEC SOIC-8 package compatibility with industrial temperature grade (-40°C to +85°C).
Technical Context
The AT24C04N-10SC implements a two-wire I²C interface with Schmitt-triggered, noise-filtered SDA and SCL inputs, supporting standard-mode (100 kHz) timing at 2.7V. Its internal architecture organizes 4096 bits into 32 pages of 16 bytes each, using a 9-bit word address for random access.
Device addressing uses A2 and A1 pins (A0 is NC), enabling up to four AT24C04N-10SC devices on a single bus. Write protection is controlled exclusively by the WP pin-tied to VCC to lock the full 4K array, or GND for normal read/write operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4096 bits (512 × 8), sufficient for firmware calibration tables or device ID storage in compact systems |
| Supply Voltage Range | 2.7V to 5.5V - supports direct interfacing with 3.3V and 5V microcontrollers without level shifting |
| I²C Clock Frequency | 100 kHz max at 2.7V - ensures reliable communication under low-voltage conditions with standard-mode timing compliance |
| Page Write Size | 16 bytes per page - enables efficient bulk writes while minimizing bus occupancy and host CPU overhead |
| Write Endurance | 1,000,000 cycles - guarantees long-term reliability in applications with frequent parameter updates (e.g., metering, sensor logging) |
| Data Retention | 100 years at +25°C - ensures persistent storage integrity across product lifetime without refresh |
| Operating Temperature | -40°C to +85°C - qualified for industrial environments including factory automation and outdoor equipment |
Pinout & Package
AT24C04N-10SC is housed in an 8-lead JEDEC SOIC (8S1) package, 0.150" wide, with gull-wing leads and standard 1.27 mm pitch. The package is RoHS-compliant and suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect | Not used in AT24C04 - left unconnected; no effect on device addressing or operation |
| A1 | Device Address Input | Hard-wired to set one bit of 2-bit device address (A1/A2), allowing up to four devices on same I²C bus |
| A2 | Device Address Input | Hard-wired to set second bit of 2-bit device address (A1/A2); determines unique I²C slave address |
| GND | Ground Reference | Return path for VCC and all logic signals; must be low-impedance to ensure noise immunity during I²C communication |
| VCC | Power Supply | Primary power input (2.7–5.5V); powers internal EEPROM array, control logic, and I/O buffers |
| WP | Write Protect Control | Hardware-enforced lock: tied to VCC disables all write operations to entire 4K memory array |
| SCL | Serial Clock Input | Positive-edge sampled clock for synchronous data transfer; open-drain compatible with I²C bus pull-up |
| SDA | Serial Data I/O | Bi-directional, open-drain data line shared across I²C bus; requires external pull-up resistor |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-triggered, filtered inputs | Suppresses EMI-induced glitches on SDA/SCL lines, eliminating false start/stop detection in noisy industrial environments |
| 16-byte page write mode | Reduces required I²C transactions by 16× versus byte-write for contiguous data, lowering bus contention and host processing load |
| Self-timed write cycle (≤10 ms) | Removes need for host polling delay management - device asserts acknowledge only after internal write completion |
| Hardware write protection via WP pin | Prevents accidental overwrites during power-up/down or firmware faults without software intervention or register configuration |
| 1 million write cycles endurance | Supports daily parameter updates for >27 years - eliminates wear-leveling firmware complexity in data-logging applications |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C04D-SSHM-T | Same 4K capacity, 1.7–5.5V supply, TSSOP-8 package; lacks -10SC's industrial temp rating (-40°C to +85°C) | Targeted at commercial-grade consumer electronics where ambient temperature stays below +70°C | Select when footprint compatibility with TSSOP is required and extended temperature operation is not needed. |
| M24C04-RMN6TP | 4K I²C EEPROM from STMicroelectronics; 1.8–5.5V, SOIC-8, industrial temp; 400 kHz max clock at 5V (vs. 100 kHz for AT24C04N-10SC at 2.7V) | Better high-speed performance at 5V but identical 2.7V timing; different device address mapping (A0–A2 all used) | Choose for designs needing faster write throughput at 5V or requiring ST's qualification pedigree in automotive subsystems. |
Compared with AT24C04N-10SC, AT24C04D-SSHM-T trades industrial temperature support for smaller TSSOP packaging, while M24C04-RMN6TP offers higher 5V speed and alternate addressing but requires layout review for A0–A2 pin usage and voltage-specific timing validation.

FAQ
What is the maximum clock frequency supported by AT24C04N-10SC at 2.7V?
The AT24C04N-10SC supports a maximum I²C clock frequency of 100 kHz when operated at 2.7V. This is specified in the AC Characteristics table under "2.7-, 2.5-, 1.8-volt" column for parameter fSCL. At 5.0V, it supports up to 400 kHz, but the -10SC suffix denotes the 2.7V–5.5V voltage grade with 100 kHz guaranteed timing at the lower end. The AT24C04N-10SC must meet tLOW ≥ 4.7 µs and tHIGH ≥ 4.0 µs under these conditions.
How many AT24C04N-10SC devices can share the same I²C bus?
Up to four AT24C04N-10SC devices can be addressed on a single I²C bus. This is enabled by hard-wiring the A2 and A1 pins to VCC or GND to configure a unique 2-bit device address; A0 is a no-connect. Each combination of A2/A1 yields a distinct 7-bit slave address (1010xx0), allowing concurrent operation without address conflict. The AT24C04N-10SC does not use A0 for addressing.
Does AT24C04N-10SC support partial page writes?
Yes, the AT24C04N-10SC supports partial page writes: the host may transmit fewer than 16 bytes within a single page write sequence, and the device will auto-increment the internal address pointer for each byte received. The remaining bytes in the 16-byte page retain their prior values. This behavior is explicitly documented in the "Page Write" section and applies identically to the AT24C04N-10SC as part of the AT24C04 family.
What is the function of the WP pin on AT24C04N-10SC?
The WP (Write Protect) pin on AT24C04N-10SC provides hardware-level write inhibition: when pulled high to VCC, it disables all write operations-including byte, page, and sequential writes-to the entire 4K memory array. When grounded, normal read/write functionality is restored. This feature operates independently of software commands and remains active during power transitions, making the AT24C04N-10SC suitable for safety-critical parameter locking.
Is AT24C04N-10SC rated for industrial temperature operation?
Yes, the AT24C04N-10SC is qualified for industrial temperature operation from -40°C to +85°C. This is confirmed by its ordering code suffix "-10SC-2.7", where "-2.7" indicates the 2.7V–5.5V voltage grade and "SC" denotes SOIC package with industrial temperature range. The datasheet specifies DC and AC characteristics across this full range, and the device undergoes screening per industrial-grade reliability standards.
