Parallax Propeller Memory Card

The Propeller Memory Card is a great platform for developing memory-intensive Propeller programs that can benefit from flash, SRAM, or a microSD card. The 13-pin SIP package works well in a breadboard or plugs directly into a Human Interface board for the P8X32A Propeller Quickstart. The flash memory is nonvolatile, and the SRAM is volatile, but has an optional solder connection to a battery.

Key Features:

  • 32 megabit (4 megabyte) non-volatile flash memory in 4 kilobyte sectors
  • 1 megabit (128 kilobyte) static RAM
  • Card slot for microSD or microSDHC card
  • Compatible with sockets on the Propeller Demo Board, or a Human Interface Board for the P8X32A Propeller Quickstart
  • Can be used with a breadboard or through-hole board for prototyping or custom projects

Note: microSD card not included; available separately.

Technical Details:

  • Voltage requirements: 3.3 VDC

  • Current requirements: 45 mA max, not including a microSD card

  • Communication: Serial Quad Interface (SQI), Quad Peripheral Interface (QPI), and Serial Peripheral Interface (SPI), including dual- and quad-SPI

  • Dimensions: 1.4 x 1.4 x 0.2 in (36 x 36 x 5 mm)

  • Operating temperature range: -40 to +185 °F (-40 to +85 °C)

Application Ideas:

  • Explore tradeoffs between different memory types
  • S
tore images and frame buffers for user interfaces

  • Store multiple files and programs
  • Execute code from external memory

  • Log large amounts of data
