| PRELIMINARY 1.28 Gbit SDRAM ELECTRONICS 3DSD1280-323H 1.28 GBit Synchronous DRAM - Hermetic package Features Organized as 40M x 32-bit. Single +3.3V 0.3V power supply Two stacks of ten 64 MBit SDRAM mounted on ceramic hermetic package Fully synchronous; all signals registered on positive edge of system clock. Internal pipelined operation; column address can be changed every clock cycle. Programmable burst lengths: 1, 2, 4, 8 or full page. Auto Precharge, includes Concurrent Auto Precharge, and Auto Refresh Modes. Self Refresh Mode LVTTL - compatible inputs and outputs Vcc and Vss are decoupled with four 10nF and four 100nF capacitors inside the module MIL-STD-883D Class S screening temperature range : -15C to +80 Pin configuration for 3DSD1024-0863S GND NC/A12* DQM BS1 BS0 A11 A10 A9 A8 GND NC Vcc A7 A6 A1 A0 Vcc A0-A12* 64 63 General Description The 3DSD1280-323H is a highly integrated Synchronous Dynamic Random Access Memory ceramic module, containing 1,342,177,280 bits. It is organized with ten banks of 128 Mbit. Each Bank has a 32-bit interface, and is selected with specific CS#. All other signals are common to the twenty 64 MBit SDRAM memories. It is particularly well suited for use in high performance and high density aerospace applications, such as solid state recorder for airbornes and satellites. The 3DSD1280-323H is packaged in a 84-pin CQFJ.
