Chipset improves memory for ATM port
control
GD Technik has introduced a new White Electronic Designs chipset family that provides a complete memory solution for the Lucent LUCTAPC640 ATM port controller (APC).
GD Technik has introduced a new White Electronic Designs chipset family that provides a complete memory solution for the Lucent LUCTAPC640 ATM port controller (APC) When used together, the two BGA devices in the family are able to replace up to eight monolithic memory products that are normally used to satisfy the APC memory requirements

Mono display enhanced for handheld applications
An enhanced version of Hitachi's popular 5.6 inch 1/4 VGA monochrome display is now available for use in industrial instrumentation and communications equipment.
This yields a 63% saving in board space.
The WED9LAPC2C16V4BC is housed in a 21 x 21mm 192 BGA package.
The device is configured as a 512K x 32bit synchronous pipeline SRAM and a 512K x 64bit synchronous DRAM array.
This provides the memory required for the control memory (CRAM) and virtual connection memory (VCRAM) ports of the APC.
The second of the two devices in the family is the WED9LAPC2B16P8BC it is configured as a 4M x 32bit synchronous DRAM and a 2M x 8bit synchronous DRAM array.
Packaged as a 153 BGA it provides the memory required for the buffer memory (BRAM) and the pointer memory (PRAM) ports.
An additional benefit of the two devices is in reducing the capacitance loading on the APC chip by over 50%, thereby improving performance and reducing I/O power.
Both devices operate from a 3.3V supply and are available in both commercial (0 to +70degC) and industrial (-40 to +85degC) operating temperature range formats.
