Product details
Overview
M24C08-FMC6TG from STMicroelectronics is an 8-Kbit I²C-compatible serial EEPROM organized as 1 K × 8 bits, operating with supply voltage from 1.7 V to 5.5 V across –40 °C to +85 °C. It supports 400 kHz and 100 kHz I²C bus modes, features 16-byte page write capability with ≤5 ms write time, and provides hardware write protection via WC pin. It is used in industrial control modules for parameter storage and calibration data retention.
For engineers reviewing the M24C08-FMC6TG datasheet, M24C08-FMC6TG pinout, M24C08-FMC6TG application, or M24C08-FMC6TG equivalent, key selection criteria include I²C voltage range compatibility (1.7–5.5 V), page write timing (≤5 ms), WC-enabled full-array write protection, and ECOPACK2-compliant UFDFPN8 (2 × 3 mm) packaging for space-constrained embedded designs.
Technical Context
The M24C08-FMC6TG implements a standard I²C slave protocol with start/stop detection, 7-bit device address plus R/W bit, and ACK/NACK handshaking. Its internal architecture includes a page latch, X/Y decoders, sense amplifiers, and HV generator for EEPROM programming - enabling byte and page writes without external high-voltage supply.
It supports three read modes: random address (via dummy write + restart), current address, and sequential read. The WC pin disables all write operations when driven high, while E2 sets the b3 bit of the device address - both pins are unconnected in the UFDFPN8 package variant, fixing E2 = 0 and WC = 0 (always writable) per datasheet Section 4.5 and Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 8 Kbit (1024 × 8), sufficient for firmware configuration tables or sensor calibration coefficients in microcontroller-based systems. |
| I²C clock frequency | Up to 400 kHz - enables fast parameter updates in real-time control loops without bus contention delays. |
| Supply voltage range | 1.7 V to 5.5 V - supports direct interface with 1.8 V logic, 3.3 V MCU peripherals, and 5 V legacy systems without level shifters. |
| Write cycle endurance | 4 million cycles - ensures reliable logging over 10+ years in data-logging applications with daily 1000 write events. |
| Data retention | 200 years at 55 °C - guarantees long-term integrity of stored calibration or security keys in unpowered storage. |
| Page size | 16 bytes - matches typical MCU cache line or packet payload sizes, minimizing partial-page overhead during bulk updates. |
| Operating temperature | –40 °C to +85 °C - qualified for industrial automation, automotive body electronics, and outdoor metering environments. |
Pinout & Package
Package: UFDFPN8 (ECOPACK2), 2 mm × 3 mm, 0.5 mm pitch, RoHS-compliant and halogen-free. Pin 1 marked by dot; no exposed thermal pad.
| 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; supports wired-AND topology. |
| 2 (SCL) | Serial Clock Input | Master-generated clock synchronizing all data transfers; rise/fall time ≤50 ns required for 400 kHz operation. |
| 3 (WC) | Write Control Input | In UFDFPN8, internally tied low - write protection disabled; device always writable unless externally controlled via software lock. |
| 4 (VSS) | Ground Reference | Primary return path for all signals; must be low-impedance and decoupled near pin with 10–100 nF capacitor. |
| 5 (VCC) | Supply Voltage | Power input for core and I/O; stable 1.7–5.5 V required before any I²C transaction; POR circuit prevents spurious writes during power ramp. |
| 6 (NC) | No Connect | Not bonded; must be left floating or grounded - no electrical function; avoids misrouting in PCB layout. |
| 7 (NC) | No Connect | Not bonded; same as Pin 6 - no routing or termination needed. |
| 8 (E2) | Chip Enable Input | In UFDFPN8, unconnected and internally read as logic 0 - fixes device address bit b3 = 0, enabling single-device addressing on shared bus. |
Key Features
| Feature | Design Value |
|---|---|
| ECOPACK2 packaging | Halogen-free, RoHS-compliant UFDFPN8 footprint reduces environmental impact and meets global regulatory requirements for industrial equipment. |
| Hardware write protection | WC pin disables all writes when high - prevents accidental overwrites during firmware updates or brown-out conditions. |
| Enhanced ESD/latch-up immunity | ±3 kV HBM ESD rating and robust latch-up immunity - ensures reliability in handling-sensitive manufacturing and field-deployed systems. |
| Polling-ready ACK response | Supports ACK polling during write cycles - eliminates fixed delay waits and enables deterministic timing in time-critical embedded firmware. |
| Roll-over sequential read | Auto-incrementing address counter wraps from 3FFh to 00h - simplifies circular buffer implementation without software address management. |
Applications
| Industrial PLC Configuration Storage | Smart Meter Calibration Data Retention |

Equivalent & Alternatives
The following parts are listed as comparable options for similar I²C EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C08D-SSHM-T (Microchip) | Same 8-Kbit size, 1.7–5.5 V, but uses different device address scheme (1010xxxR/W) and lacks WC pin - write protection implemented only via software lock bytes. | Requires firmware-level write-lock management; not drop-in for hardware-protected designs relying on WC pin assertion. | Select when board layout lacks WC routing or when unified software-controlled protection suffices. |
| BR24G08NUX-5TR (ROHM) | 8-Kbit, 1.7–5.5 V, supports 1 MHz I²C mode; includes built-in write protect register (WP) and extended temperature option (–40 °C to +105 °C). | Higher-speed bus support enables faster BOM updates; WP register offers finer-grained sector protection vs. full-array WC control. | Select for next-gen designs needing faster configuration loading or extended temp qualification beyond +85 °C. |
Compared with AT24C08D-SSHM-T and BR24G08NUX-5TR, the M24C08-FMC6TG provides fixed hardware write disable via WC pin (simplifying safety-critical lock logic), guaranteed 400 kHz timing across full voltage range, and industry-standard ECOPACK2 packaging with documented 200-year retention - making it optimal for cost-sensitive industrial and metering applications where deterministic hardware protection is prioritized over speed or extended temperature.

FAQ
Is M24C08-FMC6TG pin-compatible with other M24C08 variants like M24C08-W or M24C08-R?
No - M24C08-FMC6TG uses the UFDFPN8 (2 × 3 mm) package with specific pinout (SDA, SCL, WC, VSS, VCC, NC, NC, E2), whereas M24C08-W and M24C08-R are commonly offered in SO8N or TSSOP8 packages. While functional behavior is identical, mechanical and soldering requirements differ; PCB layout must match the DFN8 footprint and 0.5 mm pitch.
Does the WC pin function in the UFDFPN8 package?
No - per datasheet Section 4.5 and Figure 3, the WC and E2 pins are not connected in the UFDFPN8 (MC) package. Internally, WC is pulled low, disabling hardware write protection; E2 is read as logic 0, fixing the device address to 10100xxR/W. Write protection must be implemented in firmware if required.
What is the maximum supported I²C clock frequency for M24C08-FMC6TG?
The device supports up to 400 kHz I²C clock frequency across its full 1.7–5.5 V supply range and –40 °C to +85 °C temperature range, as specified in Table 8 of DS9362 Rev 7. It does not support 1 MHz operation - that capability is found only in newer series like M24M01 or BR24Gxx.
How does the address rollover behave during sequential read in UFDFPN8?
In UFDFPN8, sequential read rolls over from address 3FFh back to 00h as defined in Section 5.2.3 - unlike the DFN5 variant (which omits rollover). This enables seamless circular buffer reads without software address wraparound logic, provided the master continues clocking and acknowledges each byte until the final stop condition.
