What are the key features of M24C64-FMN6TPP?
- 64 Kbit (8192 x 8-bit) EEPROM density providing ample non-volatile storage for configuration data, calibration tables, and firmware parameters in embedded systems
- I2C Fast mode interface at up to 400 kHz enabling rapid read/write access from any I2C-capable microcontroller or processor
- Hardware write-protect pin and page-write capability (up to 32 bytes per write cycle) reducing programming time and protecting critical data from accidental overwrite
- SO-8 150 mil package with RoHS-compliant construction ensuring broad PCB compatibility and compliance with environmental regulations
What is M24C64-FMN6TPP used for?
The M24C64-FMN6TPP is used in embedded systems to store non-volatile configuration data, sensor calibration coefficients, and boot parameters that must survive power cycles without a battery. It is common in industrial sensor nodes, HVAC controllers, and consumer electronics where 8 Kbytes of I2C-accessible EEPROM provides sufficient storage for device identity records, usage logs, and system settings. The SO-8 package and standard I2C interface make it a direct drop-in for designs already using I2C peripherals, minimizing firmware changes when upgrading from smaller-density EEPROMs.

Frequently Asked Questions
What is the storage capacity and I2C speed of the M24C64-FMN6TPP, and how does page write work?
The M24C64-FMN6TPP provides 64 Kbit (8192 bytes) of EEPROM storage organized as 8-bit words, accessible via I2C at up to 400 kHz Fast mode. Page write operations allow up to 32 bytes to be written in a single I2C transaction, reducing total write time for large blocks of calibration or configuration data compared to byte-by-byte programming.
How does the hardware write-protect feature of the M24C64-FMN6TPP protect critical data in field-deployed systems?
The M24C64-FMN6TPP includes a dedicated write-protect (WP) pin that, when pulled high, blocks all write operations to the full 64 Kbit memory array. This hardware protection prevents accidental or malicious overwriting of calibration constants, device serial numbers, or firmware configuration records stored in EEPROM, which is especially important in industrial sensor nodes or medical devices where data integrity is safety-critical.
When upgrading a design from a 32 Kbit I2C EEPROM to the M24C64-FMN6TPP, what software changes are required?
Upgrading to the M24C64-FMN6TPP from a 32 Kbit I2C EEPROM typically requires only a change to the 16-bit memory address range in the driver, since the M24C64 uses 2-byte internal addresses to access all 8192 locations across its 64 Kbit array. The I2C device address (set by A0, A1, A2 pins) and 400 kHz Fast mode timing remain compatible with standard I2C EEPROM drivers, making the upgrade straightforward with minimal firmware modification.
