5114 NVRAM Module

5114 NVRAM Module

No More Batteries!

This is a premium quality Battery Eliminator / NVRAM replacement for the 5114 RAM used in arcade machines & might work for the 6514 RAM used in Zaccaria Generation 2 machines. Once installed, you can remove the batteries from your machine and your high scores / settings will be saved for many years to come!

Replaces a 2114, 5114, 5514, 6514, 9114 or compatible pinout 1024 x 4 SRAM. These modules use CYPRESS F-RAM nvram ICs rated at 151-year data retention & 100 trillion reads/writes. Module installs easily into any IC socket.

Please note some games may require removal of the existing RAM and installation of a 28-pin IC socket (included) to use this nvram module.
See the COMPATIBILITY LIST below for more info.

WHY REPLACE YOUR EXISTING RAM WITH NVRAM?
Batteries leak. Even brand new batteries from major brands have leaked a year or two later for no apparent reason and cause hundreds of dollars in repairs or replacement of boards and components affected. Upgrading to NVRAM will save you time, money and any future worry of battery damage. It's one of the best mods you can do to your games.

ARCADE GAME COMPATIBILITY

The 5114 Module should work with many arcade games that used a 2114, 5114, 5514, 6514, 9114, etc. Note that the F-RAM chips latch each address on the falling edge of the /CE (chip enable) line, so in the hardware being upgraded the /CE line must be toggled for every read/write (not tied to GND). There may also be timing or other hardware incompatibilities to take into consideration. The chip enable circuit can be verified via schematic, but the toggling of the chip enable line on every read/write would need to be verified via logic analyzer. Some games may require a 4700uf-12000uf 25v filter capacitor across the 12v power supply if the power supply is a switching supply (where the power collapses quicker than a linear supply when the game is turned off).

A few arcade games that the 5114 NVRAM is compatible with:

• Berzerk (replace RAM at location 1E and set W11 jumper for "6514" per manual)
• Blaster
• Bubbles (needs 2x of these nvram modules to replace RAM at locations 0B & 1C)
• Frenzy (replace RAM at location 1E and set W11 jumper for "6514" per manual)
• Joust
• Joust2
• Qix
• Robotron
• Sinistar
• Splat
• Stargate
• Zookeeper

*Note: Use the 5101 nvram module for Defender.

Please let us know if you've used this module successfully in other arcade games so we can add them to the list!

PINBALL COMPATIBILITY

For pinball machines, download the "Pinball NVRAM Game List" PDF document to find what type of NVRAM you need for each game you'd like to upgrade. This will also help identify what games are plug-and-play and which require soldering for installation.
