Product details
Overview
M24512E-FMN6TP from STMicroelectronics is a 512-Kbit (64-Kbyte) I²C-compatible serial EEPROM organized as 64 K × 8 bits, operating from 1.6 V to 5.5 V with support for 1 MHz Fast-mode Plus, 400 kHz Fast-mode, and 100 kHz Standard-mode I²C buses. It features configurable device address (CDA), software write protection (SWP), and a dedicated 128-byte identification page for secure parameter storage - deployed in industrial control modules requiring nonvolatile configuration retention across power cycles.
For engineers reviewing the M24512E-FMN6TP datasheet, M24512E-FMN6TP pinout, M24512E-FMN6TP application, or M24512E-FMN6TP equivalent, key selection criteria include its 4 ms typical page write time, 330 nA standby current, hardware write protection via WC pin, preprogrammable device address, and ECOPACK2-compliant SO8N/TSSOP8/UFDFPN8 packaging for space-constrained embedded systems.
Technical Context
The M24512E-FMN6TP implements a full I²C target interface with open-drain SDA and input-only SCL, supporting standard read/write sequences plus specialized register access (DTI, CDA, SWP, ID page) via unique MSB address prefixes (e.g., 111xxx for DTI, 110xxx for CDA). Its internal HV generator enables byte/page programming without external high-voltage supply.
Write control (WC) provides hardware-level memory lock: when driven high, all data writes are rejected while device select and address bytes remain acknowledged - enabling fail-safe protection during system initialization or fault conditions. The identification page supports permanent read-only locking after programming, ensuring tamper-resistant storage of calibration or security keys.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 512 Kbit (64 K × 8), enabling storage of firmware patches or multi-sensor calibration tables in compact MCU-based nodes |
| I²C speed modes | Supports 1 MHz (Fast-mode Plus), 400 kHz (Fast-mode), and 100 kHz (Standard-mode) - compatible with legacy and high-speed controllers without protocol translation |
| Page size | 128-byte pages allow efficient bulk writes; reduces I²C transaction overhead vs. byte-wise programming |
| Write cycle time | Typical 3.1 ms per byte/page - enables <10 ms configuration updates during system boot or field reprogramming |
| Supply voltage range | 1.6 V to 5.5 V - interoperable with 1.8 V logic, 3.3 V microcontrollers, and 5 V legacy systems without level shifters |
| Data retention | 200+ years at +25 °C - ensures long-term reliability in unattended infrastructure monitoring equipment |
| Endurance | 4 million write cycles - supports frequent logging or dynamic parameter adjustment in test instrumentation |
Pinout & Package
Package: SO8N (150 mil width), TSSOP8 (169 mil width), or UFDFPN8 (2 mm × 3 mm); all ECOPACK2-compliant and RoHS-qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SDA | Serial Data I/O | Open-drain bidirectional bus line; requires external pull-up; supports wired-AND with other I²C devices |
| 2: VSS | Ground Reference | Primary return path for VCC; must be low-impedance and decoupled near package pins |
| 3: SCL | Serial Clock Input | Asynchronous clock input strobing SDA transitions; no internal pull-up; synchronized internally |
| 4: WC | Hardware Write Control | Active-high global write disable; blocks all data writes while permitting address acknowledgment |
| 5–6: NC | No Connect | Unbonded die pads; must remain floating - no routing or termination allowed |
| 7: VCC | Supply Voltage | 1.6–5.5 V DC input; requires 10–100 nF ceramic decoupling capacitor placed adjacent to pin |
| 8: NC | No Connect | Unbonded die pad; electrically isolated - no connection permitted |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Device Address Register (CDA) | 8-bit register with C2/C1/C0 bits allowing up to 8 devices on same I²C bus; DAL bit enables irreversible lock for production stability |
| Software Write Protection (SWP) | Nonvolatile BP1/BP0 bits enable quarter/half/¾/full memory block protection; WPL bit prevents further SWP modification after deployment |
| Identification Page | 128-byte dedicated page with independent lock capability - stores calibrated offsets or cryptographic keys immune to accidental overwrite |
| Enhanced Reliability | 330 nA standby current and <5 μs wake-up time reduce system power budget; >4M endurance and 200-year retention meet industrial lifecycle requirements |

FAQ
What is the function of the WC pin on M24512E-FMN6TP?
The WC (Write Control) pin is an active-high hardware enable that globally disables all write operations to the memory array when driven high. During this state, device select and address bytes are still acknowledged, but data bytes receive no ACK - providing fail-safe protection against unintended writes during power transitions or system faults without requiring firmware intervention.
How does the identification page differ from main memory?
The identification page is a dedicated 128-byte area accessible via unique I²C address prefix (000xxxxx), supporting independent read/write and permanent read-only lock. Unlike main memory, it is designed for sensitive data like calibration constants or security keys - and once locked, no further writes are acknowledged, even if WC is low or SWP is disabled.
Can the configurable device address be changed after delivery?
Yes - the CDA register is writable until the Device Address Lock (DAL) bit is set to 1, which permanently freezes C2/C1/C0 values. Factory-default DAL = 0 allows field reconfiguration; setting DAL = 1 is irreversible and prevents further changes, making it ideal for production-line finalization of I²C addresses in multi-device systems.
What I²C clock frequencies does M24512E-FMN6TP support?
M24512E-FMN6TP supports three standard I²C modes: 100 kHz (Standard-mode), 400 kHz (Fast-mode), and 1 MHz (Fast-mode Plus). All modes operate across the full 1.6–5.5 V supply range and -40 °C to +85 °C temperature range, with timing parameters fully specified in the DS13657 datasheet Rev 5.
