A potential upgrade with 2Mbit memory, but requires review of the slower write cycle time.
Finding a replacement for the M24M01-RMN6TP 1Mbit I2C EEPROM requires matching its wide 1.8V-5.5V supply range and SO8 package. We analyze several alternatives from STMicroelectronics.
Slower write cycle time (10ms vs 5ms) may affect system performance.
Both parts are in a standard SO8 package, likely with compatible pinouts.
Software may need to adapt to a larger memory map and slower write timing.
No exact 1Mbit drop-in was found; the closest is an upgrade to the 2Mbit M24M02-DRMN6TP, which requires review.
Upgrade to M24M02-DRMN6TP for more memory, but validate system timing.
Timing incompatibility due to the M24M02-DRMN6TP's slower write cycle time.

| Feature / factor | M24M01-RMN6TP | M24M02-DRMN6TP | Alt 2 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SO8 | SO8 | SO8 — Form factor matches. | ||
| Interface | I2C | I2C | I2C — Interface protocol matches. | ||
| Voltage | 1.8 V ~ 5.5 V | 1.8 V to 5.5 V | 1.8 V to 5.5 V — Supply voltage range matches. | ||
| Memory Size | 1 Mbit | 2 Mbit | 2 Mbit — Candidate has double the memory capacity. | ||
| Write Cycle Time | 5 ms | 10 ms | 10 ms — Slower write time may impact system timing. |
The M24M02-DRMN6TP is a potential upgrade path, offering double the memory (2Mbit) in the same package and voltage range. However, its slower write time must be verified for your application.
