PicoROM is an 8-bit ROM emulator in a DIP-32 compatible form factor. The PicoROM can emulate ROMs up to 2MBit (256Kbytes) in size and access times of 70ns. Its size allows it to fit into almost any ROM socket regardless of how crowded the board might be. It uses the standard JEDEC pinout for a 32 pin ROM so it will generally work anywhere something like a 27C020 EPROM would work.

The PicoROM is designed for prototyping and rapid iteration. A new image can be upload in less than a second over the USB connection using a simple command line tool. If you have ever found yourself in a situation where your iteration loop requires you to pull a ROM from its socket, erase it, flash it and put it back in for every code change, then you are who this was designed for.

The PicoROM comes fully assembled and flashed with the latest firmware version. The pins are Aries Electronics coined contact headers that are gentle on sockets and easy to install and remove.

Please follow the source code and documentation links for a more in depth explanation of how the PicoROM works. The YouTube video demonstrates a real world use case. If you have questions about the product or delivery to other countries please feel free to message me.
