M24C16-RMN6TP 概要
An EEPROM (Electrically Erasable Programmable Read-Only Memory) is a non-volatile memory that retains data when power is removed, and can be electrically erased and reprogrammed. It is a type of non-volatile memory (NVM) that falls under the broader category of memory ICs, which also includes Flash, SRAM, and DRAM. EEPROMs are commonly used for storing configuration parameters, calibration data, device addresses, and small amounts of firmware that require in-system updates.
Key features of the M24C16-RMN6TP include a 400 kHz I2C interface, a write cycle time of 5 ms, and a write protect (WC) pin for hardware data protection. It supports byte and page write modes (up to 16 bytes per page), and random and sequential read modes. The device has a typical standby current of 1 uA and an active read current of 0.5 mA, contributing to its low-power profile. It is available in a Pb-free, RoHS-compliant SOIC-8 package, with an operating temperature range of -40C to +85C.
The M24C16 uses a standard I2C protocol with a 7-bit device address, where the three least significant bits (E2, E1, E0) are hardware-configurable, allowing up to eight devices on the same bus. The memory array is organized into 128 pages of 16 bytes each. The device includes a noise filter on the SCL and SDA lines to improve bus reliability in noisy environments.
Typical applications include smart meters, industrial control systems, medical devices, and consumer electronics where non-volatile storage of small amounts of data is required. The wide voltage range and low power consumption make it ideal for battery-powered IoT sensors and portable devices.
When designing with this device, ensure that the I2C bus pull-up resistors are properly sized for the bus capacitance and speed. The write protect pin should be tied to ground if not used, and decoupling capacitors should be placed close to the VCC pin to minimize noise.

設計ノート
Place a 0.1 uF decoupling capacitor close to the VCC pin (pin 8) and ground. Ensure the I2C bus pull-up resistors (typically 4.7 kOhm for 400 kHz) are connected between SDA/SCL and VCC. Keep the traces short to minimize bus capacitance and improve signal integrity.
The write protect (WC) pin must be tied to ground if write protection is not needed. Leaving it floating can cause unpredictable behavior. Also, ensure the device address pins (A0, A1, A2) are properly tied to VCC or ground to avoid address conflicts on the I2C bus.
The M24C16-RMN6TP operates from 1.8V to 5.5V. Ensure the supply voltage is within this range and stable. During write operations, the device draws additional current; a bulk capacitor (e.g., 10 uF) on the VCC line can help maintain voltage stability.
