Product details
Overview
M24C01-RMN6TP from STMicroelectronics is a 1-Kbit (128-byte) I²C-compatible serial EEPROM organized as 128 × 8 bits, operating with supply voltage from 1.8 V to 5.5 V and supporting Fast Mode (400 kHz) and Standard Mode (100 kHz) I²C bus protocols. It features hardware write protection via WC pin, 16-byte page write capability, and operates across –40 °C to +85 °C for industrial embedded control and sensor calibration storage.
For engineers reviewing the M24C01-RMN6TP datasheet, M24C01-RMN6TP pinout, M24C01-RMN6TP application, or M24C01-RMN6TP equivalent, key selection considerations include its 1.8 V minimum VCC support, ECOPACK2-compliant UFDFPN5 (1.7 × 1.4 mm) package, 4 million write cycles, 200-year data retention at 55 °C, and hardware-based full-array write disable functionality.
Technical Context
The M24C01-RMN6TP implements a slave-only I²C interface with start/stop detection, ACK/NACK handshaking, and internal address counter auto-increment. Its block diagram integrates HV generator + sequencer, page latches, X/Y decoders, and sense amplifiers to enable byte- and page-write operations without external high-voltage programming.
It supports three read modes - random address, current address, and sequential - all independent of WC state, and uses a power-on-reset (POR) circuit to prevent spurious writes during power-up. The DFN5 package omits E0–E2 pins, fixing device address to 1010000x, requiring exclusive bus allocation for that address range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 1-Kbit (128 × 8 bits), sufficient for firmware ID, calibration coefficients, or configuration flags in space-constrained designs. |
| I²C clock frequency | Up to 400 kHz (Fast Mode), enabling ~400-byte/s write throughput with page writes and reducing bus occupancy vs. Standard Mode. |
| Supply voltage range | 1.8 V to 5.5 V - supports direct interfacing with 1.8 V logic, 3.3 V microcontrollers, and 5 V legacy systems without level shifters. |
| Page size | 16 bytes - allows efficient bulk parameter updates (e.g., 16-channel sensor offsets) in one I²C transaction, minimizing protocol overhead. |
| Data retention | 200 years at 55 °C - ensures long-term reliability for unattended equipment like utility meters or remote sensors. |
| Write endurance | 4 million cycles at 25 °C - supports daily reconfiguration over >10 years in field-upgradable devices such as industrial HMI or IoT edge nodes. |
| Operating temperature | –40 °C to +85 °C - qualified for automotive cabin modules, industrial PLC I/O modules, and outdoor environmental monitors. |
| ESD protection | ±3000 V HBM - enhances robustness in handling-sensitive assembly environments and electrostatic-prone end-user installations. |
Pinout & Package
Package: UFDFPN5 (ECOPACK2), 1.7 mm × 1.4 mm, 0.5 mm pitch, RoHS-compliant and halogen-free. Pin 1 marked by top-side 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 arbitration. |
| 2: SCL | Serial Clock Input | Master-generated clock synchronizing all data transfers; rising edge samples SDA, falling edge drives SDA transitions. |
| 3: WC | Write Control Input | Active-high hardware lock: when high, disables all write operations (byte/page) while still acknowledging device address and read requests. |
| 4: VCC | Supply Voltage | 1.8–5.5 V DC input; requires local 10–100 nF ceramic decoupling capacitor placed adjacent to pin for noise immunity and stable POR behavior. |
| 5: VSS | Ground Reference | System ground return for all signals and internal circuitry; must be low-impedance connection to minimize ground bounce during write cycles. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware write protection | WC pin disables entire memory array writes without software overhead-critical for preventing corruption during brown-out or firmware update failures. |
| 16-byte page write | Reduces I²C transaction count by up to 16× vs. byte writes, lowering CPU load and bus contention in real-time systems. |
| Address flexibility (E0–E2) | Omitted in UFDFPN5 package; fixes I²C address to 1010000x, simplifying bus topology but requiring dedicated address slot on shared I²C lines. |
| POR and latch-up immunity | Integrated power-on-reset prevents spurious writes during ramp-up; enhanced latch-up protection meets industrial system reliability requirements. |
| ECOPACK2 packaging | Halogen-free, RoHS-compliant 1.7 × 1.4 mm DFN enables ultra-compact PCB layouts in wearables, medical patches, and miniaturized industrial sensors. |

FAQ
What is the function of the WC pin on M24C01-RMN6TP?
The WC (Write Control) pin is an active-high hardware lock that disables all write operations-including byte and page writes-when driven high. It does not affect read operations. This provides deterministic, zero-software-overhead protection against accidental or malicious memory corruption during power transients, firmware updates, or system resets.
Does M24C01-RMN6TP support I²C clock stretching?
No, the M24C01-RMN6TP does not implement clock stretching. As a slave device, it relies on internal timing (tW ≤ 5 ms max) and expects the master to manage bus timing. Masters must poll the ACK bit after a write command to detect completion before issuing subsequent commands, rather than holding SCL low.
Can M24C01-RMN6TP be used with a 1.2 V microcontroller I/O?
No. Although the device operates down to 1.8 V VCC, its I²C interface requires logic-high input thresholds of ≥0.7×VCC and logic-low thresholds of ≤0.3×VCC. With VCC = 1.8 V, minimum valid high input is 1.26 V - below typical 1.2 V GPIO high levels. Level-shifting is required for interoperability with true 1.2 V systems.
How is device addressing handled in the UFDFPN5 package?
In the UFDFPN5 package, E0–E2 pins are not bonded out, fixing the device select code to 1010000x (where x = R/W bit). This eliminates address configuration flexibility but guarantees deterministic addressing. No other I²C device using address 1010xxxx may share the same bus segment without conflict.
