3 Description
The TMF0008 is an 8K bits serial Non-Volatile
Memory (NVM) device containing a unique factoryprogrammed
48-bit identification number and 8-bit
family code. The memory is FRAM-based and has
higher endurance (106 R/W cycles) compared to other
NVM technologies.
The device communicates over a SDQ™ single-wire
interface and supports both 15.4Kbps and 90Kbps
speeds. The SDQ pin acts as communication and
power for the device. The memory is organized as
thirty memory pages of 256 bits each. Data is written
to a 32-byte scratchpad for verification before being
copied 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 range. This operating range covers most
applications and at the same time enables optimized
design for low-cost development.
