Product details
Overview
M24M02-DRCS6TP/K from STMicroelectronics is a 2-Mbit I²C-compatible EEPROM organized as 256 K × 8 bits, operating from 1.8 V to 5.5 V over –40 °C to +85 °C. It supports 1 MHz/400 kHz/100 kHz I²C bus modes, features a 256-byte page size, and includes an additional write-lockable identification page for secure parameter storage in industrial control and automotive subsystems.
For engineers reviewing the M24M02-DRCS6TP/K datasheet, M24M02-DRCS6TP/K pinout, M24M02-DRCS6TP/K application, or M24M02-DRCS6TP/K equivalent, key selection criteria include I²C speed compatibility, 256-byte page write timing, identification page lockability, supply voltage range, and SO8N ECOPACK2 package footprint for space-constrained PCB layouts.
Technical Context
The device implements a full I²C slave protocol with start/stop detection, ACK/NACK handshaking, and 7-bit device addressing with E2-pin configurable LSB. Its internal architecture includes ECC logic across 4-byte groups, transparently correcting single-bit errors during read operations without software intervention.
Write control (WC) enables hardware-level memory protection: when driven high, it disables all writes to the main array while still acknowledging device select and address bytes. The identification page-exclusive to M24M02-DR variants-is accessible via dedicated 1011b device type identifier and supports permanent lock via a specific byte-write command with A10 = 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory capacity | 2 Mbit (256 Kbyte), directly addressable via 18-bit addressing including A17–A0 |
| I²C bus speed | Up to 1 MHz - enables fast firmware updates and configuration loading in real-time systems |
| Page size | 256 bytes - matches typical MCU flash sector sizes for atomic configuration block writes |
| Write time | ≤10 ms per byte or page - deterministic latency critical for time-sensitive boot or calibration sequences |
| Endurance | 4 million write cycles - supports frequent logging or runtime parameter tuning in industrial edge nodes |
| Data retention | 200 years at +25 °C - ensures long-term reliability in unattended infrastructure monitoring devices |
| Supply voltage | 1.8 V to 5.5 V - interoperable with 3.3 V and 5 V microcontrollers without level-shifting |
Pinout & Package
Package: SO8N ECOPACK2 (150 mil width), RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SDA | Serial data I/O | Open-drain bidirectional bus line requiring external pull-up; supports wired-AND with other I²C slaves |
| 2: SCL | Serial clock input | Master-generated clock synchronizing all data transfers; must meet tHD:DAT and tSU:DAT timing windows |
| 3: DU | Unused terminal | No connection required; if routed, must be tied to VSS to prevent floating node noise coupling |
| 4: VCC | Power supply | Accepts 1.8–5.5 V; requires local 10–100 nF decoupling capacitor adjacent to pin for stable operation |
| 5: VSS | Ground reference | Primary return path for VCC; must be low-impedance and co-located with VCC decoupling |
| 6: WC | Write control input | Active-high hardware lock disabling all writes to main memory array; floats low to enable writes |
| 7: E2 | Chip enable input | Configures LSB of 7-bit I²C address (0 or 1); determines device select code (1010x or 1011x) |
| 8: DU | Unused terminal | No signal connection; ties to VSS if physically connected to avoid ESD susceptibility |
Key Features
| Feature | Design Value |
|---|---|
| Identification page with permanent lock | 256-byte dedicated area for storing calibration coefficients or security keys; irreversible RO lock prevents tampering after deployment |
| ECC on 4-byte groups | Single-bit error correction during reads improves data integrity in electrically noisy environments without firmware overhead |
| Hardware write protection (WC) | Pin-level disable of all memory writes eliminates risk of accidental corruption during power transitions or firmware faults |
| Wide VCC range (1.8–5.5 V) | Eliminates need for external voltage translators when interfacing with mixed-voltage SoCs or legacy 5 V controllers |
| SO8N ECOPACK2 packaging | Standardized 150-mil SOIC footprint enables drop-in replacement and automated assembly compatibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24CM02-SSHD-T | 2 Mbit I²C EEPROM, 1.7–5.5 V, no identification page, max 1 MHz, 1 million write cycles | Lacks hardware-locked ID page and ECC; lower endurance limits use in high-write-frequency logging | Select when cost sensitivity outweighs need for secure parameter storage or extended cycling |
| M95M02-DRMN6TP | 2 Mbit SPI EEPROM, 1.8–5.5 V, 20 MHz SPI interface, no ID page, 3 million write cycles | Uses SPI instead of I²C; incompatible bus protocol requires MCU peripheral reconfiguration | Choose only if system already uses SPI peripherals and board layout cannot accommodate I²C routing |

FAQ
What is the function of the E2 pin on the M24M02-DRCS6TP/K?
The E2 pin sets the least significant bit (b3) of the 7-bit I²C device address. When tied to VCC, it configures the device select code as 10101xx; when tied to VSS, it becomes 10100xx. This allows two M24M02-DR devices to share the same I²C bus without address conflict, enabling dual-parameter storage in compact systems.
Can the identification page be unlocked after it is permanently locked?
No-the identification page lock is irreversible. Once the lock identification page instruction is executed (with A10 = 1 and data byte xxxx xx1x), the page becomes read-only for the lifetime of the device. This one-time programming ensures tamper-proof storage of calibration keys or security credentials in certified applications.
How does the ECC feature affect write endurance distribution?
ECC operates on 4-byte groups: writing any single byte also cycles the other three bytes in its group. Endurance is budgeted per group-not per byte-so the sum of write cycles across all four bytes in a group must not exceed 4 million. This requires firmware-aware allocation of frequently updated parameters across distinct ECC groups.
Is the SO8N package of M24M02-DRCS6TP/K compatible with standard SOIC-8 footprints?
Yes-the SO8N ECOPACK2 package has 150 mil width and standard 1.27 mm pitch, matching JEDEC MS-012AC. Pin 1 marking is a dot or notch; pin numbering follows counterclockwise order from pin 1. No layout adaptation is needed for existing SOIC-8 land patterns.
