3 Description

The TMF0064 is a 64Kbit serial non-volatile

memory (NVM) device containing a unique factoryprogrammed

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 a SDQ™ single-wire

interface and supports both 15.4kbps and 90kbps

speeds. The SDQ 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.
