Product details
Overview
AT24C04N-10SU-2.7 from Microchip Technology is a 4-kbit (512 × 8) two-wire serial EEPROM with 2.7V to 5.5V supply operation, 16-byte page write capability, 400 kHz I²C clock compatibility at 2.7V+, and hardware write protection via the WP pin. It serves as nonvolatile configuration storage in embedded control systems requiring low-power, industrial-temperature operation.
For engineers reviewing the AT24C04N-10SU-2.7 datasheet, AT24C04N-10SU-2.7 pinout, AT24C04N-10SU-2.7 application, or AT24C04N-10SU-2.7 equivalent, key selection criteria include its 2.7V–5.5V VCC range, 16-byte page write mode, WP-enabled hardware data lock, SOIC-8 package footprint, and guaranteed 1 million write cycles with 100-year data retention.
Technical Context
The AT24C04N-10SU-2.7 implements a standard I²C-compatible two-wire interface with open-drain SDA and edge-triggered SCL, supporting bidirectional data transfer and Schmitt-trigger filtered inputs for noise immunity. Its internal address space is organized as 32 pages of 16 bytes each, requiring a 9-bit word address for random access.
Write protection is enforced by the dedicated WP pin: tied to VCC, it locks the full 4K array; tied to GND, full read/write functionality is enabled. The device enters low-power standby mode after STOP condition receipt and supports acknowledge polling to detect write cycle completion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4096 bits (512 words × 8 bits), enabling storage of firmware calibration tables or device configuration registers |
| Supply Voltage Range | 2.7V to 5.5V - compatible with 3.3V and 5V logic domains without level shifting |
| I²C Clock Frequency | Up to 400 kHz at VCC ≥ 2.7V - supports high-speed parameter updates in real-time control loops |
| Page Write Size | 16 bytes per page - reduces write transaction overhead vs. byte-write-only devices |
| Endurance & Retention | 1 million write cycles / 100 years data retention - suitable for field-updatable systems with infrequent but critical writes |
| Operating Temperature | –40°C to +85°C - validated for industrial and automotive under-hood environments |
| Write Protect Function | Hardware-enforced full-array lock via WP pin - prevents accidental overwrites during power transients or firmware faults |
Pinout & Package
AT24C04N-10SU-2.7 is packaged in an 8-lead JEDEC SOIC (8S1), 0.150" wide, RoHS-compliant green package with NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No-connect (NC) for AT24C04 | Internally disconnected; may be tied to GND or left floating without functional impact |
| A1 | Device address input | Hardwired to set one of four possible I²C slave addresses (A2/A1 only used; A0 unused) |
| A2 | Device address input | Hardwired to select among four AT24C04 devices on same I²C bus (A2/A1 define 2-bit address) |
| GND | Ground reference | Return path for VCC and signal currents; must be low-impedance for noise immunity |
| VCC | Power supply | 2.7V–5.5V main supply; decoupling capacitor required within 1 cm of pin |
| WP | Write protect control | Active-high hardware lock: VCC = full-array write disable; GND = normal R/W operation |
| SCL | Serial clock input | Positive-edge sampled clock; requires external pull-up; max 400 kHz at 2.7V+ |
| SDA | Serial data I/O | Open-drain bidirectional line; shared across multiple I²C devices; requires external pull-up |
Key Features
| Feature | Design Value |
|---|---|
| Two-wire serial interface | Reduces PCB routing complexity vs. SPI; shares SCL/SDA lines across multiple peripherals |
| Schmitt-trigger, filtered inputs | Enables reliable operation in electrically noisy industrial environments (e.g., motor drives, PLCs) |
| 16-byte page write mode | Cuts firmware update time by up to 15× vs. byte-write for contiguous 16-byte blocks (e.g., sensor calibration sets) |
| Hardware write protection (WP) | Eliminates need for software-based lock mechanisms; prevents corruption during brown-out or reset |
| 100-year data retention | Supports maintenance-free deployment in infrastructure equipment (e.g., smart meters, base stations) |

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, SOIC-8, 1.7V–5.5V VCC range; uses newer "D" series die with enhanced ESD robustness (4kV HBM) | Preferred for new designs targeting extended voltage margin and higher ESD immunity in handheld medical devices | Select when upgrading legacy designs requiring improved latch-up immunity and broader VCC headroom |
| M24C04-RMN6TP | 4K I²C EEPROM in SOIC-8; 1.8V–5.5V operation; 1M endurance; identical pinout but different device address mapping (A0/A1/A2 all active) | Requires firmware address reconfiguration; suited for STMicro-based platforms already using M24Cxx family | Choose for ST ecosystem alignment or where A0/A1/A2 address flexibility is needed for multi-device bus expansion |
Compared with AT24C04N-10SU-2.7, AT24C04D-SSHM-T offers wider voltage tolerance and better ESD resilience, while M24C04-RMN6TP provides identical capacity and package but demands address logic adaptation-both serve as drop-in replacements only after validation of timing, voltage, and addressing behavior.

FAQ
What is the maximum I²C clock frequency supported by AT24C04N-10SU-2.7?
The AT24C04N-10SU-2.7 supports up to 400 kHz I²C clock frequency when operated at VCC ≥ 2.7V. At lower voltages (e.g., 1.8V), the maximum rated speed drops to 100 kHz. This specification is confirmed in Table 5 of the official datasheet and applies directly to the AT24C04N-10SU-2.7 variant with -2.7 suffix.
Is AT24C04N-10SU-2.7 pin-compatible with other AT24Cxx EEPROMs in SOIC-8 package?
Yes, AT24C04N-10SU-2.7 shares identical SOIC-8 pinout (8S1) and I²C interface signaling with AT24C01A, AT24C02, AT24C08A, and AT24C16A in the same package. However, memory size, page length, and device addressing differ - e.g., AT24C04N-10SU-2.7 uses only A2/A1 for addressing (A0 is NC), unlike AT24C02 which uses A2/A1/A0.
How does the Write Protect (WP) pin function on AT24C04N-10SU-2.7?
On AT24C04N-10SU-2.7, the WP pin enables hardware-level write protection: when pulled high to VCC, it disables all write operations to the entire 4K memory array; when grounded, full read/write access is restored. This behavior is electrically enforced and remains active regardless of I²C command state - a key safety feature for AT24C04N-10SU-2.7 in fail-safe systems.
What is the endurance and data retention specification for AT24C04N-10SU-2.7?
The AT24C04N-10SU-2.7 guarantees 1 million write/erase cycles and 100 years of data retention at +25°C, as specified in Table 5 and the Features section of the datasheet. These values are characterized and validated across the full industrial temperature range (–40°C to +85°C), making AT24C04N-10SU-2.7 suitable for long-lifecycle infrastructure applications.
Does AT24C04N-10SU-2.7 support partial page writes?
Yes, AT24C04N-10SU-2.7 supports partial page writes: up to 16 bytes can be written in a single transaction, and fewer than 16 bytes may be sent - the internal address counter increments automatically, wrapping within the current 16-byte page boundary. This capability is explicitly documented for the AT24C04 in the "Page Write" section and applies to AT24C04N-10SU-2.7.
