64Kb FRAM with 64-bit unique ID, Single Wire SDQ™ interface compatible with 1-Wire® protocol

The TMF0064 is a

64Kbit serial non-volatile memory (NVM) device containing a unique

factory-programmed 48-bit identification number and an 8-bit family code. The memory

is FRAM-based and has high endurance (106 R/W cycles) in comparison to

alternate NVM technologies.

The device communicates over an SDQ™ single wire serial interface compatible with

1-wire® protocol and supports both 15.4kbps and 90kbps speeds. The

SDQ™ single wire serial

interface pin acts as both the communication and power pin for the

device. The memory is organized as 253 memory pages with 256 bits

per page. Data is first written to a 32-byte scratchpad. The data is

verified before copying to FRAM memory.

The device operates at two supply voltage ranges,

3.3V ±5% and 5V ±5%, and is specified from -10°C to 85°C. The operating range covers

most applications and enables peak design for low-cost development.
