TMF0008
- 7680 Bits of FRAM for storage of user-programmable configuration data partitioned into multiple pages
- Single-wire interface to reduce circuit board routing
- Communicates at 15.4Kbps (standard Speed) and 90Kbps (overdrive Speed)
- Switch-point hysteresis and filtering embedded in the device to improve performance in the presence of noise
- IEC 61000-4-2 level 4 ESD protection (±8kV contact, ±15kV air, typical)
- Factory-programmed unique 64-bit identification number
- Operating temperature range: -10°C to 85°C
- Operating voltage range: 5V ±5% (standard and overdrive speed)
- Operating voltage range: 3.3V ±5% (standard speed only)
- Available in TO-92 (LP), WSON (DRS) and SO (PS) packages
The TMF0008 is an 8K bits serial Non-Volatile Memory (NVM) device containing a unique factory-programmed 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.
