Key Features
- 64-Kbit (8 KB) I2C EEPROM with 8192 x 8-bit word organization for configuration and parameter storage
- Rated for 105°C extended temperature operation supporting industrial and automotive accessory applications
- 1 million write endurance cycles with 40-year data retention for reliable long-term non-volatile storage
Applications
The M24C64-DRDW8TP/K serves as non-volatile configuration storage in industrial sensors, smart meters, and automotive body control modules requiring reliable data retention at temperatures up to 105°C. Its 8 KB capacity is sufficient for calibration tables, device identity records, and boot configuration parameters in embedded systems. The standard I2C interface with hardware address pins allows up to 8 devices on a single 2-wire bus for multi-zone data logging applications.

Frequently Asked Questions
How much data can the M24C64-DRDW8TP/K store and what typical embedded use cases fit within 8 KB?
The M24C64-DRDW8TP/K provides 65536 bits organized as 8192 x 8-bit words (8 KB total), which accommodates up to 64 calibration coefficients at 4 bytes each, a 4 KB firmware configuration table, device serial numbers, or several hundred sensor log entries at 16 bytes per record.
How many M24C64-DRDW8TP/K devices can share a single I2C bus and how are they differentiated?
Up to 8 M24C64-DRDW8TP/K devices can share one I2C bus simultaneously, with each addressed via a 3-bit hardware address set by the A0, A1, and A2 pins tied to V CC or GND, giving addresses from 0x50 to 0x57 within the standard I2C 7-bit address space.
What write endurance and data retention figures does the M24C64-DRDW8TP/K guarantee for industrial long-life applications?
The M24C64-DRDW8TP/K guarantees a minimum of 1 million write cycles per byte location and 40 years of data retention at 55°C, which translates to over 15 years retention at 105°C under Arrhenius acceleration modeling, supporting industrial equipment with 10 to 20 year service life requirements.
Why is the M24C64-DRDW8TP/K's 105°C temperature rating significant for automotive accessory or under-hood sensor designs?
Automotive under-hood and HVAC zone environments regularly reach 85°C to 100°C ambient. The 105°C operation rating of the M24C64-DRDW8TP/K provides the necessary 5°C to 20°C thermal margin above those ambient levels, whereas standard commercial-grade 85°C EEPROMs would fail to meet reliability targets without costly thermal enclosures.
