The TMF0020 is a 20K bit 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) compared to other NVM technologies.
The device communicates over an SDQ™ single-wire
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 pin
and power pin for the device. The memory is organized as 80 memory pages with 256
bits per page. Data is first written to a 32-byte scratchpad. Then 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.
