Flash Memory for the BS2p+ and Propeller

xanatos

Got a notification today of a new Farnell product, Flash Memory chips, available in 4, 8, 16, 32 & 64 meg varieties, SPI, 3.3v, SOIC 8 pin configuration. Very tiny nonvolatile memory - if that would be useful to anyone, here's the address for more info:

They're cheap (looks like about $1 USD to about $4 USD, depending on how the currencies convert), no minimum quantities... Could these possibly be something useful enough for Parallax to buy a stock of?

Just thought I'd let folks know.

These look like the ones used in the C3 and some 3rd party boards and made by Microchip and Winbond as well as others. The Winbond driver in the Object Exchange should work although the chips probably identify themselves differently from what's coded in the table in the start routine for the Winbond driver. The driver uses the identification information to tell how big they are.

Excellent. Another QuadSPI source. I have 2x 4 bit wide Propeller objects for the Winbond parts using for the JCACHE interface and a simpler program/read object. The XBASIC language is now running programs which are stored in the flash. C language compilers are also being ported.

Propeller based SpinSocket-Flash modules using these parts are available for $50 each with 4MB Flash with choice of low power battery operation or higher power LDO regulator. A simple PropPlug based development board is also available with 2 empty stackable sockets for $50.

Can't wait for QuadSPI SRAM to show up Until then I have limited quantities of an 8 chip solution.
