The Great Search – Replacement SPI FRAM #TheGreatSearch #DigiKey @DigiKey @Adafruit
(Video) We think FRAM chips are the most underrated storage chips engineers can use – they’re excellent for datalogging! They also solve the biggest frustration when people try to stream data to EEPROM, SD card or Flash memory: erase times for blocks can stretch to hundreds of milliseconds, and you often need to write a whole block at a time. SRAM is nice but will erase itself when power is lost. If you need to burst-write data to a reliable storage medium that is OK with having power cut – FRAM is great. We have a few FRAM breakouts but we’ve found some chips are discontinued/obsolete.
Let’s see what options we have for replacements – a good lesson in how to read and understand PCNs.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
