Product details
Overview
M24C02-FDW6TP from STMicroelectronics is a 2-Kbit (256-byte) I²C-compatible serial EEPROM organized as 256 × 8 bits, operating as a slave device on standard and fast-mode I²C buses up to 400 kHz, with 1.7 V to 5.5 V supply range over –40 °C to +85 °C, and hardware write protection via WC pin - used for configuration storage in embedded microcontroller systems.
For engineers reviewing the M24C02-FDW6TP datasheet, M24C02-FDW6TP pinout, M24C02-FDW6TP application, or M24C02-FDW6TP equivalent, key selection criteria include its 16-byte page size, 5 ms max write cycle time, DFN5 (UFDFPN5) 1.7 × 1.4 mm ECOPACK2 package, and full compatibility with I²C address 1010000R/W in systems requiring low-voltage operation and high endurance.
Technical Context
The M24C02-FDW6TP implements a synchronous serial interface compliant with Philips I²C-bus specification, supporting both byte and page write modes with automatic address increment and roll-over within pages. Its internal architecture includes a page latch, HV generator for EEPROM programming, and start/stop detection logic.
It features hardware write protection via the WC pin (active-high), fixed device address 1010000R/W for DFN5 packages (E0–E2 unconnected), and a power-on reset circuit ensuring no spurious writes during power-up. The SDA line operates open-drain with required external pull-up, and ACK/NACK protocol governs data flow control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2 Kbit (256 × 8-bit array), enabling storage of firmware flags, calibration data, or user settings in space-constrained designs |
| I²C clock frequency | Up to 400 kHz (Fast mode), allowing efficient data transfer without CPU overhead in real-time embedded systems |
| Supply voltage range | 1.7 V to 5.5 V across full temperature range (–40 °C to +85 °C), supporting direct interfacing with 1.8 V, 3.3 V, and 5 V MCUs |
| Page size | 16 bytes, defining maximum contiguous write length per instruction - critical for minimizing I²C transaction count and write latency |
| Write endurance | 4 million cycles at 25 °C, ensuring reliable reprogramming over product lifetime in field-updatable devices |
| Data retention | 200 years at 55 °C, guaranteeing nonvolatile storage integrity for long-lifecycle industrial and automotive applications |
| Write cycle time | ≤5 ms for byte or page write, setting worst-case delay before next I²C command can be issued |
Pinout & Package
Package: UFDFPN5 (ECOPACK2), 1.7 mm × 1.4 mm, 5-pin DFN with exposed pad (no thermal pad connection specified), RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SDA | Serial Data I/O | Open-drain bidirectional bus line - requires external pull-up resistor; carries address, data, and ACK/NACK signals |
| 2: SCL | Serial Clock Input | Master-generated clock synchronizing all data transfers; rising edge samples SDA, falling edge allows SDA change |
| 3: WC | Write Control Input | Active-high hardware lock - disables all write operations when driven high, preventing accidental memory corruption |
| 4: VCC | Supply Voltage | 1.7–5.5 V DC input; decoupling capacitor (10–100 nF) required near pin for stable operation during write cycles |
| 5: VSS | Ground Reference | System ground return path for all internal logic and EEPROM programming circuits; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| Hardware write protection | WC pin enables system-level immunity to firmware bugs or noise-induced writes - no software dependency required |
| Low-voltage operation | 1.7 V minimum VCC supports direct integration with battery-powered or energy-harvesting subsystems |
| Page write capability | 16-byte burst writes reduce I²C bus occupancy by >90% vs. sequential byte writes for block updates |
| Enhanced reliability | 4M write cycles and 200-year data retention meet industrial-grade requirements for unattended operation |
| I²C address simplification | Fixed 1010000R/W address in DFN5 eliminates external address pin routing and reduces BOM count |
Applications
| Industrial Sensor Calibration | Smart Meter Configuration Storage |
|---|---|
Use Scenario: Storing factory-calibrated sensor offset/gain coefficients and temperature compensation tables in environmental monitoring nodes. IC Role / Device Role / Timing Role: Nonvolatile configuration register accessed at boot via I²C; no timing-critical interaction beyond standard bus handshake.

IC Role / Device Role / Timing Role: Robust EEPROM interfaced directly to 3.3 V MCU I²C port, surviving load-dump transients via system-level protection. Use Value: Qualified for AEC-Q100 Grade 2 (–40 °C to +105 °C ambient), with WC pin preventing corruption during ECU reset sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C02D-SSHM-T | 2-Kbit I²C EEPROM; 1.7–5.5 V; 400 kHz; SO8N/TSSOP8 only - no DFN5 option; 1-million-cycle endurance | Lacks DFN5 footprint - unsuitable for ultra-compact PCBs; lower endurance limits reprogramming frequency | Select if SO8N/TSSOP8 assembly is preferred and endurance >1M cycles is sufficient |
| BR24G02NUX-10 | 2-Kbit I²C EEPROM; 1.6–5.5 V; 1 MHz clock; DFN6 (1.6 × 1.6 mm); 1-million-cycle endurance; built-in error correction | Higher speed but larger footprint; ECC adds complexity for simple storage; not qualified for automotive temp range | Select only if 1 MHz throughput is mandatory and board area permits DFN6 |
Compared with AT24C02D-SSHM-T and BR24G02NUX-10, the M24C02-FDW6TP uniquely combines DFN5 miniaturization, 4-million-cycle endurance, and full –40 °C to +85 °C operation - making it optimal for space- and reliability-critical industrial IoT endpoints.

FAQ
What is the function of the WC pin on M24C02-FDW6TP?
The WC (Write Control) pin is an active-high hardware enable that disables all write operations to the entire memory array when driven high. When WC is low or floating, writes are permitted. This provides fail-safe protection against unintended memory modification during power transitions, firmware errors, or EMI events - independent of software control.
Does M24C02-FDW6TP support standard and fast-mode I²C speeds?
Yes, M24C02-FDW6TP supports both standard-mode (100 kHz) and fast-mode (400 kHz) I²C operation. Its AC characteristics are fully characterized up to 400 kHz under all valid VCC and temperature conditions. No external speed-select configuration is needed - bus clock rate is determined solely by the master controller.
Can M24C02-FDW6TP be used with 1.8 V microcontrollers?
Yes - M24C02-FDW6TP operates reliably from 1.7 V to 5.5 V across its full –40 °C to +85 °C temperature range, making it compatible with 1.8 V logic families. Its input thresholds (0.2VCC/0.8VCC) and output drive strength ensure robust signal integrity when interfaced directly to 1.8 V MCUs without level-shifting circuitry.
Is the DFN5 package of M24C02-FDW6TP lead-free and RoHS-compliant?
Yes, the UFDFPN5 (DFN5) package is ECOPACK2 certified - fully RoHS-compliant (2011/65/EU) and halogen-free. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and supports standard Pb-free reflow profiles, including peak temperatures up to 260 °C.
