Product details
Overview
M24C04-FMC6TG from STMicroelectronics is a 4-Kbit I²C-compatible serial EEPROM organized as 512 × 8 bits, operating at up to 400 kHz clock frequency with 1.7 V to 5.5 V supply voltage (full temperature range) and -40 °C to +85 °C ambient operation. It features 16-byte page write capability, hardware write protection via WC pin, and >4 million write cycles. Used in industrial control modules for parameter storage and calibration data retention.
For engineers reviewing the M24C04-FMC6TG datasheet, M24C04-FMC6TG pinout, M24C04-FMC6TG application, or M24C04-FMC6TG equivalent, key selection considerations include I²C voltage compatibility (1.7 V min), DFN5 package footprint constraints, WC-controlled full-array write protection, and guaranteed 200-year data retention at 55 °C.
Technical Context
The M24C04-FMC6TG implements a standard I²C slave protocol with start/stop detection, ACK/NACK handshaking, and 7-bit device addressing (1010xxxR/W). Its internal architecture includes a page latch, X/Y decoders, sense amplifiers, and HV generator for EEPROM programming - enabling byte and page writes within ≤5 ms.
It supports three read modes: random address (via dummy write + restart), current address (auto-incremented), and sequential (ACK-driven streaming). The WC pin disables all write operations when high, while E1/E2 pins are unconnected in the UFDFPN5 (DFN5) package - fixing device address bits b3–b2 to 00 per Table 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Kbit (512 × 8 bits) - sufficient for firmware configuration, sensor calibration tables, or device ID storage in space-constrained designs. |
| I²C clock frequency | Up to 400 kHz - enables fast parameter updates without requiring high-speed MCU peripherals or custom timing logic. |
| Supply voltage range | 1.7 V to 5.5 V (full temp range); 1.6 V to 5.5 V (restricted temp) - supports direct interfacing with 1.8 V logic and legacy 5 V systems. |
| Write endurance | 4,000,000 cycles at 25 °C - ensures reliable field recalibration or logging over multi-year product lifetimes. |
| Data retention | 200 years at 55 °C - guarantees long-term integrity of stored calibration coefficients or security keys without refresh. |
| Page size | 16 bytes - aligns with common MCU cache line sizes and simplifies firmware buffer management during bulk writes. |
| Operating temperature | -40 °C to +85 °C - qualified for industrial automation, automotive body electronics, and outdoor metering applications. |
Pinout & Package
Package: UFDFPN5 (DFN5), 1.7 mm × 1.4 mm, 5-pin, RoHS-compliant and halogen-free (ECOPACK2). Pin 1 marked by dot; no exposed thermal pad. E1 and E2 pins are not connected - device address fixed to 101000xx.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SDA | Serial Data I/O | Open-drain bidirectional bus line; requires external pull-up; shares bus with other I²C slaves. |
| 2: SCL | Serial Clock Input | Master-generated clock; rising edge samples SDA; falling edge allows SDA transition. |
| 3: WC | Write Control Input | Active-high hardware lock: disables all write operations when driven high; floating or low enables writes. |
| 4: VCC | Supply Voltage | 1.7–5.5 V power input; decoupling capacitor (10–100 nF) required near pin for stable write cycles. |
| 5: VSS | Ground Reference | Return path for all signals and internal charge pump; must be low-impedance connection to system GND. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware write protection | WC pin disables entire memory array from writes - eliminates need for software-level lock bits or firmware validation. |
| Extended low-voltage operation | 1.7 V minimum supply across full -40 °C to +85 °C range - enables direct integration with ultra-low-power MCUs and battery-backed systems. |
| Enhanced reliability | 4M write cycles and 200-year data retention - reduces field failure risk in infrequently updated but mission-critical storage (e.g., energy meter tariffs). |
| Small-footprint packaging | UFDFPN5 (1.7 × 1.4 mm) - saves PCB area in wearables, IoT sensors, and compact industrial controllers where board space is premium. |
| Robust I/O protection | ESD rating ≥3 kV HBM and latch-up immunity per JEDEC JESD78 - improves manufacturing yield and field robustness in noisy environments. |

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 (Microchip) | Same 4-Kbit capacity, 1.7–5.5 V, but uses 8-pin SOIC/TSSOP; no WC pin - write protection relies on software or external logic. | Larger footprint; lacks hardware write lock - unsuitable where physical tamper resistance is required. | Select if SOIC mounting is preferred and WC functionality is unnecessary. |
| BR24G04NUX-3TR (ROHM) | 4-Kbit, 1.6–5.5 V, DFN6 package (2.0 × 2.5 mm); includes WP pin (functionally identical to WC) but supports 1 MHz I²C mode. | Wider DFN6 footprint; higher speed - beneficial for high-throughput logging but increases layout complexity. | Select if 1 MHz I²C bandwidth is needed and board area permits larger DFN6. |
Compared with AT24C04D-SSHM-T and BR24G04NUX-3TR, the M24C04-FMC6TG uniquely combines DFN5 miniaturization, guaranteed 1.7 V operation across full temperature range, and dedicated WC pin - making it optimal for space- and voltage-constrained industrial and automotive edge nodes.

FAQ
What is the function of the WC pin on M24C04-FMC6TG?
The WC (Write Control) pin is an active-high hardware lock that disables all write operations to the entire 4-Kbit memory array when driven high. When WC is low or floating, writes are enabled. This provides deterministic, glitch-immune protection against accidental overwrites during power transients or firmware errors - independent of software state.
Does M24C04-FMC6TG support I²C clock stretching?
No, the M24C04-FMC6TG does not support clock stretching. As a standard I²C slave EEPROM, it relies on internal timing for write cycles (≤5 ms) and responds with ACK/NACK only. During internal write operations, it ignores SCL/SDA until completion - requiring the master to poll ACK or wait tW before issuing new commands.
Can M24C04-FMC6TG be used with 1.6 V supply?
Yes, but only under restricted temperature conditions: 1.6 V operation is permitted only when ambient temperature is ≥0 °C for write operations and ≥-20 °C for read operations. Full-spec operation (1.7 V to 5.5 V) applies across the full -40 °C to +85 °C range - consult Section 7 of DS9387 Rev 6 for exact derating limits.
How is device addressing handled in the DFN5 package?
In the UFDFPN5 (DFN5) package, E1 and E2 pins are not connected. Per Table 2 of DS9387, this fixes bits b3–b2 of the 7-bit device address to 00, resulting in a base address of 101000xx. No external pull-up/down resistors are needed for E1/E2, and no other device with address 1010xxxx may share the same I²C bus segment.
