Memory Module (TWR-FRAM) Compatible with the Freescale Tower System
(3V battery included) 256-Kb I2C Serial F-RAM 256-Kb l2C TCXO/ Processor Companion 256-Kb I2C RTC/ Processor Companion 256-Kb SPI RTC/ Processor Companion Requires use with Tower System processor module and elevator modules (TWR-ELEV) - sold separately 8-bit nonvolatile GPIO State Saver Primary (Functional) Connections
How to build your TWR-FRAM Download software from www.ramtron.com/go/TWR-FRAM Step 1 Download and install software from www.ramtron.com/go/TWR-FRAM. Download Quick Start Guide and supporting files. Step 2 Install 3V lithium battery on the TWR-FRAM board. The clip is rigid; please use care when installing the battery. Step 3 Locate the Elevator Modules (sold separately), identified by the four card-edge connections. Step 4 Identify each Elevator Module as either Primary Elevator (white connections) or Secondary Elevator (black connections). Step 5 Plug primary connections side of the TWR-FRAM board to the Primary Elevator. Place the TWR-FRAM in top position of the Elevator (see inset photo). This provides easy access to the jumper pins. Step 6 Identify the primary and secondary card edges of the Processor Module (TWR-K53N512 or similar device) and any additional modules you add to your tower system. Step 7 Plug the primary card edge of each module into the Primary (functional) Elevator. Step 8 Place the Secondary Elevator module onto the secondary card edges. Step 9 Follow instructions in the Quick Start Guide. read me first
