M24C01-RMN6TP - 1Kbit I2C EEPROM, SOIC-8 | STMicroelectronics
MPN： M24C01-RMN6TP ✓ 啟用中M24C01-RMN6TP 概覽
An EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory that can be electrically erased and reprogrammed. It is a key component in the memory hierarchy, sitting between volatile RAM and permanent storage like flash. EEPROMs are used to store small amounts of configuration data, calibration constants, and device parameters that must persist across power cycles. In the broader system, EEPROMs are part of the memory IC category, which includes ROM, RAM, and flash, and are essential for applications requiring data retention without power.
Key features of the M24C01-RMN6TP include a wide operating voltage range (2.5V to 5.5V), I2C interface with clock frequencies up to 400 kHz, and a low-power design with a standby current of 1 uA (typical). The device offers a write cycle time of 5 ms, ensuring fast programming, and supports both byte and page write modes. The SOIC-8 package is industry-standard, making it easy to integrate into existing PCB designs. The device is RoHS compliant and operates over a temperature range of -40C to +85C.
Technically, the M24C01 uses a floating-gate transistor architecture for non-volatile storage, with a built-in charge pump for programming. The I2C interface allows for simple two-wire communication (SCL and SDA), with the device address set via three pins (E0, E1, E2), enabling up to 8 devices on a single bus. The write protect pin (WC) provides hardware protection against accidental writes, and the device supports both sequential and random read operations.
Typical applications include storing calibration data in industrial sensors, configuration parameters in consumer electronics, and system settings in automotive modules. The wide voltage range and low power consumption make it suitable for battery-powered devices, while the I2C interface simplifies integration with microcontrollers.
When designing with this device, ensure proper pull-up resistors on the SCL and SDA lines (typically 4.7 kOhm) and consider the write cycle time when updating data. The WC pin should be tied to ground for normal operation or to VCC for write protection. For high-reliability applications, consider the automotive-grade variant M24C01-RMN6TP/A.

主要差異化特點
- Automotive-grade variant available (對比AT24C01C-SSHM-B)
- Wider page size (16 bytes) (對比AT24C01C-SSHM-B)
- Same-brand family compatibility (對比CAT24C01LI-G)
設計說明
Place pull-up resistors (typically 4.7 kOhm) on the SCL and SDA lines. The pull-up resistors should be connected to the same supply voltage as the EEPROM (VCC). For high-speed I2C (400 kHz), keep the bus capacitance below 400 pF. Place the pull-up resistors close to the EEPROM to minimize trace length and reduce noise.
Ensure the write protect (WC) pin is properly connected. If left floating, it may cause unpredictable write protection. Tie WC to ground for normal operation or to VCC for write protection. Also, respect the write cycle time (5 ms) after each write command; initiating a write before the cycle completes can corrupt data.
Decouple the VCC pin with a 0.1 uF ceramic capacitor placed as close to the pin as possible. This helps filter noise and ensures stable operation. The M24C01-RMN6TP has a standby current of 1 uA, but during write operations, current spikes can occur; the decoupling capacitor helps absorb these transients.
