A Recall of 3D PLUS ECO System around FPGA


72b DDRII module 3D2D4G72UB3652

The space community show a big interest to use the new Xilinx

RHBD V-5 (SIRF), which has more powerful computing

capabilities, and also need more speedy memory to work with.

Moreover, The SIRF V5 has built-in ECC hardware to directly

support 72b DDR2 interface with 8-bit ECC on a 64-bit

boundary.

3D2D4G72UB3652 Key Features:

Organized as 64Mx72b

4 chips of 1Gbit + 1 chip for ECC

Jedec standard 1.8V I/0 (SSTL_18 compatible)

Guaranteed Frequency = 333 MHz

8 internal banks per die for concurrent operation

On-Die Termination

191 leaded or lead-free balls.

Available temperature range :

0°C to +70°C

-40°C to +85°C

Or Specific temperature range

Radiation Tolerance:

TID > 75 krad(Si)

SEL LET Threshold > 60MeV.cm²/mg

SEU and SEFI characterized


Key Benefits

The 3D2D4G72UB3478 is packaged in a 191 balls BGA with 1.27mm pitch and leaded balls option for Space application.

Using the 3D2D4G72UB3652 will bring the benefits:

-All boards components can be procured in space grade

-ITAR free to guarantee worldwide delivery

-Qualified radiation tolerant die

-Easy assembly process thanks to space grade BGA with 1.27mm pitch and leaded balls

-Better signal integrity and space saving on the board!

Board area

savings!


The DDR2+DDR2 TR concept

Functional diagram:

Module supply (VDD, VAUX)

Comparators (VTT, VTT sense)

Command and protection

(Enable)

Switches and filter (VTT)

The DDR2 TR is a sink/source Double Data Rate

(DDR) termination regulator specifically designed for

low input voltage, low-noise and high reliability

systems.

Provide a VTT termination voltage to reference DDR2

(3D2D4G72UB3478: 4 chips of 1Gb + 1 chip for ECC)

3D PLUS module.


Source and Sink Current capability up to ±1A

Tight regulation of VTT to REF_IN (ripple ±40mV) – within DDR2 operating frequency limits

Reference voltage can be set externally (REF_IN) and buffered inside the module (REF_OUT)

Standby mode for low-power consumption (Enable)

Thermal protection (in case of internal over temperature or short circuit)

No external input/output filters needed

Compliant with JEDEC standard (JESD8-15A)

Main Features

Radiation Hardened by design:

Total Dose : >50Krad(Si)

SEL,SET Threshold >

80MeV.cm²/mg

Temperature Range -40°C / +105°C

Package SOP24, Size 20x20x14mm

ITAR Free
