CYPRESS SEMICONDUCTOR FM25W256-G NVRAM, FRAM, 256 Kbit, 32K x 8bit, SPI, SOICThe FM25W256 G is a 256Kbit (32K 8bit) SPI FRAM (Ferroelectric Random Access Memory) device in 8 pin SOIC package. This non volatile memory reads and writes similar to RAM. It provides reliable data retention for 151 years while eliminating complexities, overhead and system level reliability problems caused by serial flash, EEPROM and other non volatile memories. Unlike serial flash and EEPROM, the FM25W256 performs write operations at bus speed. No
The FM25W256-G is a 256Kbit (32K � 8bit) SPI FRAM (Ferroelectric Random Access Memory) device in 8 pin SOIC package. This non volatile memory reads and writes similar to RAM. It provides reliable data retention for 151 years while eliminating complexities, overhead and system level reliability problems caused by serial flash, EEPROM and other non volatile memories. Unlike serial flash and EEPROM, the FM25W256 performs write operations at bus speed. No write delays are incurred. Data is written to the memory array immediately after each byte is successfully transferred to device. The next bus cycle can commence without need for data polling. In addition, the device offers substantial write endurance compared with other non volatile memories. The FM25W256 provides substantial benefits to users of serial EEPROM or flash as hardware drop-in replacement.
- High endurance 100 trillion (10^14) read/writes
- Automotive grade AEC-Q100 qualified
- Advanced high reliability ferroelectric process
- Up to 20MHz frequency
- Sophisticated write protection scheme
- Low power consumption
- Active current of 250�A at 1MHz
- Typical standby current of 15�A
- Wide operating voltage range from 2.7V to 5.5V
- Operating temperature range from -40�C to 85�C

Good for smaller dogs too
Style: Tipsy Rosé
This dog toy states it's for large dogs (50+ lbs) but I bought it for my 12 lbs dog anyway, and Im glad I did because she loves it. Keeps her entertained. So much better than just handing her treats. When I hear it rolling across the floor I know she's busy and I dont need to worry about what she's up to. The hole is a good size for treats to fit in but she still has to work to get them out.

Long lasting high entertainment toy
Style: Tipsy Rosé
I was gifted one of these for my puppy and it is a fabulous toy. I put in dried liver chunks with at least one that is a bit of a tight fit so it drags out the experience for him. It’s highly durable, gets dragged around and pushed under furniture, and shows tooth marks but is still very effective. I also appreciate it’s easy to clean.
