Product details
Overview
M24512-RMC6TG from STMicroelectronics is a 512-Kbit (64 Kbyte) I²C-compatible serial EEPROM organized as 64 K × 8 bits, operating from 1.8 V to 5.5 V with 1 MHz clock support. It features 128-byte page write capability, >4 million write cycles, and 200-year data retention. Used in industrial control modules for parameter storage and calibration data backup.
For engineers reviewing the M24512-RMC6TG datasheet, M24512-RMC6TG pinout, M24512-RMC6TG application, or M24512-RMC6TG equivalent, key selection factors include supply voltage range (1.8–5.5 V), I²C bus mode compatibility (100 kHz/400 kHz/1 MHz), write protection via WC pin, ECOPACK2®-compliant TSSOP8 package, and identification page functionality (M24512-D variant only).
Technical Context
The device implements a slave-only I²C interface with hardware-based chip enable (E0–E2) addressing and write control (WC) for full-array lockout. Internal ECC logic operates transparently across groups of four bytes to correct single-bit read errors without protocol modification.
Memory organization supports random, sequential, and current-address read modes, plus byte and page write operations - all synchronized to SCL with ACK/NACK handshaking. The internal address counter auto-increments post-read/write, and roll-over behavior is defined at page and array boundaries.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C512B-SSHL-T (Microchip) | Same 512 Kbit density, but 1.7–5.5 V supply and no WC pin; uses software write protect only. | Lacks hardware-level write disable - unsuitable where fail-safe lockout is required during brown-out. | Select if cost sensitivity outweighs need for hardware write lock and ECC. |
| BR24G512FJ-3GE2 (ROHM) | 512 Kbit, 1.7–5.5 V, includes WC pin and 128-byte page, but rated only to +105 °C (not automotive-grade). | Higher temp rating enables under-hood use, but lacks AEC-Q200 qualification and ECOPACK2® compliance. | Prefer for extended-temperature industrial controls where automotive qualification is unnecessary. |
Compared with AT24C512B and BR24G512FJ, M24512-RMC6TG uniquely combines hardware write control (WC), ECC error correction, ECOPACK2® environmental compliance, and −40 °C to +85 °C operation - making it optimal for safety- and reliability-critical embedded systems.

FAQ
What is the function of the WC pin on M24512-RMC6TG?
The WC (Write Control) pin is an active-high hardware lock that disables all write operations to the entire memory array when driven high. When WC is low or floating, writes are enabled. This provides fail-safe protection against accidental writes during power-up, brown-out, or firmware glitches - independent of software state.
Does M24512-RMC6TG support the identification page feature?
No - the identification page (128-byte locked read-only section) is exclusive to M24512-D order codes. M24512-RMC6TG is the R-version (1.8–5.5 V operation) without identification page functionality. Only M24512-D variants support write/lock/read of the ID page using device select code 1011b.
How does ECC work in M24512-RMC6TG, and does it affect write endurance?
ECC operates transparently across every group of four consecutive bytes, correcting single-bit errors during reads. During writes, ECC logic automatically updates all four bytes in the group - meaning cycling one byte consumes ¼ of the group's 4-million-cycle budget. This is documented in Table 12 of DS6520 Rev 31.
Can M24512-RMC6TG be used in place of M24512-WMC6TG?
Yes, with voltage consideration: M24512-RMC6TG operates from 1.8 V to 5.5 V, while M24512-WMC6TG requires ≥2.5 V. In 3.3 V or 5 V systems, they are functionally and pin-compatible. However, in 1.8 V designs, only the R-version is valid - the W-version will not initialize or respond on the I²C bus.
