Key Features
- 64 Kbit (8 KB) dual-interface EEPROM accessible via both NFC ISO 15693 RF and I2C at 400 kHz, enabling contactless data read/write
- RF energy harvesting from NFC field allows memory access even when the host system is powered off, ideal for smart packaging and asset tagging
- Password-protected memory segments with configurable read/write access rights for secure data storage up to 64 Kbit
- Compact TSSOP-8 package with operating voltage from 1.8 V to 5.5 V, suitable for battery-constrained wearables and IoT nodes
- Endurance of 1,000,000 write cycles and data retention of 40 years ensuring long-term reliability in industrial and consumer applications
Applications
The M24SR64-YDW6T/2 is used in smart packaging, healthcare wearables, and industrial asset tracking where contactless NFC programming of 8 KB configuration or calibration data is needed without powering the host system. Its dual I2C interface at 400 kHz allows the connected microcontroller to read sensor logs or update device parameters at runtime while an NFC reader retrieves the same data wirelessly. The device also fits electronic shelf labels, medical disposables, and consumer electronics accessories requiring secure, non-volatile parameter storage in a space-constrained TSSOP-8 footprint.

Frequently Asked Questions
What is the memory capacity and interface speed of the M24SR64-YDW6T/2?
The M24SR64-YDW6T/2 provides 64 Kbit (8,192 bytes) of EEPROM storage organized as 8 KB of 8-bit words. The I2C interface operates at up to 400 kHz in Fast mode, while the NFC RF interface complies with ISO 15693 allowing contactless read/write access at 13.56 MHz carrier frequency from a typical read range of up to 10 cm.
How does the dual-interface design of the M24SR64-YDW6T/2 benefit IoT and smart packaging applications?
The dual-interface design lets a host microcontroller update 8 KB of configuration or sensor data over I2C at 400 kHz while an NFC reader retrieves or writes the same memory contactlessly via ISO 15693 RF at 13.56 MHz without any wired connection. In smart packaging this means a factory programmer can initialize 64 Kbit of product data over NFC during final assembly while the embedded MCU reads calibration constants over I2C at runtime, eliminating a dedicated programming connector.
What write endurance and data retention does the M24SR64-YDW6T/2 guarantee for industrial designs?
STMicroelectronics specifies a minimum write endurance of 1,000,000 erase/write cycles per byte and a data retention period of 40 years at 55°C. These figures make the device suitable for industrial configuration registers and calibration tables that are updated frequently but must retain values reliably over the product lifetime. The wide supply range of 1.8 V to 5.5 V also accommodates both 3.3 V and 5 V system rails without level shifters.
Can the M24SR64-YDW6T/2 be read via NFC when the host board is unpowered?
Yes. The M24SR64 family includes RF energy harvesting from the 13.56 MHz NFC field, which supplies the internal logic with enough power to respond to ISO 15693 commands and transfer up to 8 KB of stored data even when the host PCB's VCC rail is off. This capability is critical for medical disposables and smart labels that must deliver device history or configuration data to an NFC reader before being inserted into powered equipment.
What package does the M24SR64-YDW6T/2 use and what are the supply voltage limits?
The device is housed in an 8-pin TSSOP package with a 4.4 mm body width and 0.65 mm pin pitch, occupying minimal PCB area. It operates from 1.8 V to 5.5 V supply voltage and across a temperature range of -40°C to +85°C, covering both consumer and industrial operating conditions. The compact TSSOP-8 footprint and low standby current below 5 µA make it well suited for coin-cell-powered or energy-harvesting nodes.
