Product details
Overview
M24512-DRMB6TG from STMicroelectronics is a 512 Kbit (64 Kbyte) I²C-compatible serial EEPROM with three Chip Enable inputs (E0, E1, E2), Write Control (WC) pin, and an additional lockable 128-byte Identification Page. It operates across 1.8 V to 5.5 V, supports I²C Fast-mode Plus (1 MHz), and delivers ≤5 ms byte/page write times. It is used in industrial control modules for secure device identification and configuration storage.
For engineers reviewing the M24512-DRMB6TG datasheet, M24512-DRMB6TG pinout, M24512-DRMB6TG application, or M24512-DRMB6TG equivalent, key selection criteria include I²C bus speed compatibility (1 MHz/400 kHz/100 kHz), triple CE addressing flexibility, WC-enabled hardware write protection, and Identification Page lockability for production-line parameter binding.
Technical Context
The M24512-DRMB6TG implements a slave-only I²C interface with full protocol compliance across Standard, Fast, and Fast-mode Plus speeds. Its memory array is organized as 64 K × 8 bits with 128-byte page boundaries, and it includes dedicated logic to decode device select codes using external E0–E2 pins for multi-device bus addressing.
It features dual operational modes: standard memory array access (device address 0xA0–0xA7) and Identification Page access (device address 0xB0–0xB7), both requiring explicit WC = 0 for writes and supporting ECC-assisted write cycling. The WC pin provides hardware-level inhibition of all memory writes when driven high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 512 Kbit (64 Kbytes) EEPROM, enabling storage of firmware patches or calibration data in space-constrained embedded systems. |
| I²C speed support | Up to 1 MHz (Fast-mode Plus), allowing high-throughput configuration updates without CPU intervention in real-time control loops. |
| Write time | ≤5 ms per byte or per 128-byte page, minimizing bus occupation and enabling deterministic timing in time-critical boot sequences. |
| Supply voltage | 1.8 V to 5.5 V operation, supporting direct interfacing with 1.8 V microcontrollers and legacy 5 V industrial backplanes. |
| Identification Page | 128-byte dedicated page with permanent lock capability (via WC + specific command), used to store immutable device serial numbers or manufacturing lot codes. |
| Data retention | ≥40 years at 25 °C, ensuring long-term reliability for infrastructure equipment with 10+ year service lifecycles. |
| Endurance | 1 million write cycles per memory location, sufficient for daily firmware update logging over 27 years. |
Pinout & Package
Package: SO8 (MW), 208 mils body width, ECOPACK2® RoHS-compliant and halogen-free plastic small outline package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E0 | Chip Enable input | LSB of 3-bit device address; tied high/low to configure unique I²C slave address among up to 8 devices on same bus. |
| E1 | Chip Enable input | Mid-bit of 3-bit device address; enables flexible topology design without address conflicts in modular systems. |
| E2 | Chip Enable input | MSB of 3-bit device address; allows single-bus management of multiple sensor nodes or power modules. |
| SDA | Serial Data bidirectional line | Open-drain I/O requiring external pull-up; supports wire-OR with other I²C peripherals for shared bus arbitration. |
| SCL | Serial Clock input | Master-synchronized clock input; tolerates open-drain or push-pull drivers depending on system synchronization needs. |
| WC | Write Control input | Hardware write lock: high = all memory writes inhibited, including Identification Page; critical for preventing field corruption. |
| VCC | Supply voltage | 1.8–5.5 V power rail; decoupling capacitor (10–100 nF) required near pin for stable internal write cycle execution. |
| VSS | Ground reference | Return path for VCC; must be low-impedance connection to avoid noise-induced ACK failures during I²C transactions. |
Key Features
| Feature | Design Value |
|---|---|
| Triple Chip Enable addressing | Enables up to eight identical M24512-DR devices on one I²C bus without software address remapping or bus switches. |
| Lockable Identification Page | 128-byte page can be permanently locked to Read-only after programming, preventing overwrite of factory-set device IDs or calibration constants. |
| Noise-immune inputs | Schmitt-trigger SCL/SDA and input noise filters suppress >50 ns glitches, ensuring robust operation in electrically noisy industrial environments. |
| Enhanced reliability | Integrated ECC and >1M write cycles + 40-year data retention meet IEC 61508 SIL-2 requirements for safety-critical storage. |
| Wide voltage range | 1.8 V to 5.5 V operation eliminates level-shifting components when interfacing with mixed-voltage SoCs or legacy controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C512-SSHL-T (Microchip) | 400 kHz max I²C speed; no Identification Page; single CE pin; 1.7–5.5 V supply. | Lacks hardware lockable ID page and triple CE addressing; suitable only for simple configuration storage without production-line binding. | Select when bus speed ≤400 kHz suffices and device identification is handled in software or external secure element. |
| BR24G512FJ-3GE2 (ROHM) | 1 MHz I²C; 128-byte page; no dedicated WC pin; write protection via software command only. | Relies on software-controlled lock instead of hardware WC pin; vulnerable to firmware bugs or reset-induced corruption. | Choose only in cost-sensitive consumer designs where hardware write lock is not mandated by safety or security standards. |
Compared with AT24C512-SSHL-T and BR24G512FJ-3GE2, the M24512-DRMB6TG uniquely combines 1 MHz I²C, triple CE addressing, hardware WC pin, and lockable Identification Page-making it the only option meeting industrial traceability and functional safety requirements for production-line parameter binding.

FAQ
What is the function of the WC pin on M24512-DRMB6TG?
The WC (Write Control) pin is a hardware-level write inhibit input. When driven high, it disables all write operations-including byte, page, and Identification Page writes-regardless of I²C commands sent. This prevents accidental or malicious overwrites during power transients, EMI events, or firmware errors. WC is internally pulled low when unconnected, enabling normal write functionality.
How does the Identification Page differ from the main memory array?
The Identification Page is a dedicated 128-byte memory region accessible only via I²C device address 0xB0–0xB7 (vs. 0xA0–0xA7 for main array). It supports write and lock commands not available in the main array. Once locked, its contents become permanently read-only-even after power cycles-and cannot be erased or rewritten, making it ideal for immutable device identity data.
Can M24512-DRMB6TG operate reliably at 1.8 V while sustaining 1 MHz I²C communication?
Yes. The device is fully specified for 1.8 V to 5.5 V operation and supports 1 MHz Fast-mode Plus I²C at all voltages in this range. At 1.8 V, AC timing parameters-including tLOW, tHIGH, and tBUF-meet I²C specification limits per Table 15 of the datasheet, provided bus capacitance and pull-up resistor values comply with Figure 6 guidelines.
What package type does M24512-DRMB6TG use, and what does "MB6TG" signify?
M24512-DRMB6TG uses the SO8 (MW) package: 8-lead plastic small outline, 208 mils body width, ECOPACK2®-compliant. In ST's part numbering scheme, "MB6TG" indicates SO8W package (MB), industrial temperature grade (6), tape-and-reel packaging (T), and RoHS/Green compliance (G). Pin 1 marking follows standard SO8 orientation with notch or dot.
