Product details
Overview
M24C08-FCT6TP/T from STMicroelectronics is an 8-Kbit I²C-compatible serial EEPROM organized as 1 K × 8 bits, operating 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 includes 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-FCT6TP/T datasheet, M24C08-FCT6TP/T pinout, M24C08-FCT6TP/T application, or M24C08-FCT6TP/T equivalent, key selection criteria include supply voltage range (1.7–5.5 V), I²C clock compatibility (up to 400 kHz), page size (16 bytes), write endurance (4 million cycles), and package-specific pin mapping (TSSOP8 with E2/SDA/SCL/WC/VCC/VSS).
Technical Context
The M24C08-FCT6TP/T 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 (auto-incremented), and sequential (multi-byte stream with roll-over). Write control (WC) disables all writes when high; E2 sets b3 of device address and is unconnected in TSSOP8 variant per DS9362 Rev 7 Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 8 Kbit (1024 × 8), sufficient for firmware configuration, sensor calibration tables, or device ID storage in space-constrained designs. |
| I²C speed | Up to 400 kHz fast-mode operation, enabling sub-250 µs address+data transfer for single-byte writes in real-time systems. |
| Page size | 16 bytes per page - defines maximum contiguous write length before wrap-around; critical for optimizing write latency in logging applications. |
| Write time | ≤5 ms max for byte or page write - determines minimum interval between successive write commands; impacts system responsiveness during parameter updates. |
| Supply range | 1.7 V to 5.5 V (full temp range), supporting direct interface with 1.8 V logic, 3.3 V microcontrollers, and 5 V legacy systems without level shifters. |
| Data retention | 200 years at 55 °C - ensures long-term reliability for medical, industrial, or infrastructure equipment with infrequent field maintenance. |
| Endurance | 4 million write cycles at 25 °C - allows daily reconfiguration over >10 years in embedded controllers managing dynamic settings. |
Pinout & Package
Package: TSSOP8 (DW), 169 mil width, RoHS-compliant and halogen-free (ECOPACK2). Pin 1 marked by notch or dot; pin numbering follows standard counter-clockwise layout from top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E2) | Chip enable input | Sets b3 of 7-bit device address (1010b); tied to VSS or VCC to select one of four possible I²C addresses on shared bus. |
| 2 (SDA) | Serial data I/O | Open-drain bidirectional line - requires external pull-up; shares bus with other I²C slaves; handles address, data, and ACK/NACK signaling. |
| 3 (SCL) | Serial clock input | Master-generated clock (≤400 kHz); sampled on rising edge for data input; controls timing of all read/write transfers. |
| 4 (WC) | Write control input | Active-high hardware lock - disables all write operations (byte/page) when driven high; floating or low enables writes. |
| 5 (VSS) | Ground reference | Return path for all signals and internal circuitry; must be low-impedance and decoupled near package pins. |
| 6 (NC) | No connect | Not bonded internally; left unconnected on PCB; no electrical function or routing required. |
| 7 (VCC) | Supply voltage | Power source (1.7–5.5 V); requires local 10–100 nF ceramic decoupling capacitor to suppress noise during internal write cycles. |
| 8 (NC) | No connect | Not bonded internally; left unconnected on PCB; no electrical function or routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.7–5.5 V) | Enables direct integration with mixed-voltage systems (e.g., 1.8 V MCU + 5 V analog front-end) without level-shifting circuitry. |
| Hardware write protection (WC pin) | Prevents accidental overwrites during power transients or firmware bugs - critical for safety-critical calibration data integrity. |
| 16-byte page write | Reduces I²C bus occupancy vs. byte writes - cuts total transaction time by ~85% when storing 16-byte sensor records or network keys. |
| Enhanced ESD/latch-up immunity | Withstands ±3 kV HBM ESD and operates reliably under industrial noise conditions - reduces need for external protection components. |
| 200-year data retention | Validated at 55 °C; ensures stored parameters remain intact over full product lifecycle in uncooled enclosures or remote deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial 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 1 MHz I²C fast-mode-plus; lacks WC pin - write protection relies on software lock or external GPIO. | Preferred where higher throughput is needed and MCU firmware can manage write-enable sequencing. | Select if system already uses Microchip EEPROM portfolio and requires faster bus speeds; verify SDA/SCL drive strength compatibility. |
| BR24G08NUX-10 (ROHM) | 8 Kbit, 1.6–5.5 V, supports 1 MHz I²C; includes WP pin (functionally identical to WC) and built-in write cycle interrupt (INT pin) not present in M24C08-F. | Suitable for designs needing hardware notification of write completion without polling ACK. | Choose when reducing CPU overhead during EEPROM writes is critical; note BR24G08NUX-10 uses DFN8 package - check board layout compatibility. |
Compared with AT24C08D-SSHM-T and BR24G08NUX-10, the M24C08-FCT6TP/T offers proven industrial temperature stability and ECOPACK2 compliance out-of-box, while trading off interrupt signaling and ultra-fast I²C for lower cost and broader legacy design reuse.

FAQ
What is the function of the E2 pin on M24C08-FCT6TP/T?
The E2 pin sets bit b3 of the 7-bit I²C device address (1010b), allowing up to four M24C08 devices on the same bus. In the TSSOP8 package, it must be hard-wired to VSS or VCC - floating is not recommended as it reads as low. This pin is unconnected in DFN5 and WLCSP variants.
Can M24C08-FCT6TP/T operate at 1.6 V?
No - the M24C08-FCT6TP/T is rated for 1.7 V to 5.5 V across the full –40 °C to +85 °C range. While the base M24C08-F supports 1.6 V under restricted temperature conditions (e.g., TA ≥ 0 °C for write operations), this specific TSSOP8 variant (CT6TP/T) does not guarantee 1.6 V functionality per DS9362 Rev 7 Tables 8 and 16.
How does the WC pin affect read operations?
The WC pin has no effect on read operations: reads proceed normally regardless of WC state (high, low, or floating). Only write instructions (byte or page) are blocked when WC is driven high; read instructions always return valid data and increment the internal address counter.
Is the TSSOP8 package of M24C08-FCT6TP/T pin-compatible with SO8N?
No - although both are 8-pin packages, TSSOP8 (DW) and SO8N (MN) have different pinouts. In TSSOP8, pins 6 and 8 are NC; in SO8N, those positions carry functional signals. Direct PCB replacement requires layout revision. Refer to DS9362 Figure 2 (TSSOP8) vs. Figure 19 (SO8N) for exact mapping.
