Product Specifications


The SCS750® single board computer for space is DDC's answer to the space industry's need for medium- to high-performance computing. The SCS750 combines the latest generation of IBM PowerPC® processor with large amounts of volatile and non-volatile storage and a variety of interfaces in an industry standard 6u cPCI form factor.

Any radiation upset (SEU) is transparently corrected. The user never has to worry about executing a bad instruction or accessing corrupt information. Software development is simplified by using the industry standard VxWorks operating environment. The SCS750's powerful processing capability and high availability make it the ideal choice for data processing or spacecraft control applications.

DDC offers a range of Operational Amplifiers (Op-Amps) and a Comparator which include DDC's proprietary RAD-PAK® shielding. RAD-PAK® is a hermetic ceramic package shielding technology that reduces the Total Ionizing Dose (TID) received by the semiconductor components in the package by orders of magnitude from the total ionizing dose environment exterior to the package. This allows us to put commercial semiconductors with only moderate total dose tolerance in the high total dose environments encountered in space.

DDC offers a range of Analog-to-Digital Converters featuring up to 16-bit resolution and speeds up to 41 MSPS, which include DDC's proprietary RAD-PAK® shielding. Rad-Pak® is a hermetic ceramic package shielding technology that reduces the Total Ionizing Dose (TID) received by the semiconductor components in the package by orders of magnitude from the total ionizing dose environment exterior to the package. This allows us to put commercial semiconductors with only moderate total dose tolerance in the high total dose environments encountered in space.

The products with "LP" in their part number, have Latch-up Protection Technology (LPT). This is a DDC designed custom ASIC that is capable of sensing the on-set of latch-up, removing power from the protected device, isolating input/output signals from external circuitry and finally restoring power and normal operation after sufficient time for the effects of the single event to dissipate.

DDC offers a wide range of memory products, including PROM, EEPROM, SRAM, SDRAM, and NOR & NAND flash. any of these products are available either with DDC's proprietary RAD-PAK® shielding, or in rad-tolerant packages.

Rad-Pak® is a hermetic ceramic package shielding technology that reduces the total ionizing dose (TID) received by the semiconductor components in the package by orders of magnitude from the total ionizing dose environment exterior to the package. This allows us to put commercial semiconductors with only moderate total dose tolerance in the high total dose environments encountered in space.

Rad-tolerant devices are available in a hermetic ceramic package with a guaranteed TID tolerance at the die level. The EEPROM are also available in DDC's proprietary Xray-PAK® shielding, a hermetic ceramic package shielding technology that eliminates any line-of-sight radiation penetration to the semiconductors inside the package. This allows the effective shielding of x-rays from a nuclear weapon.

DDC's radiation-hardened, hybrid, Nuclear Event Detectors (NED) sense ionizing radiation pulses generated by a nuclear event, such as the detonation of a nuclear weapon, and rapidly switches its output from the normal high state to a low state with a propagation delay time of less than 20ns. The active low Nuclear Event Detection signal (NED) is used to initiate a wide variety of circumvention functions, thus preventing upset and burnout of electronic components. The NED output is also used to initiate both hardware and software recovery. This high-speed, 14-pin hybrid detector is used in electronic systems as a general-purpose circumvention device to protect memory, stop data processing, and drive power supply switches as well as signal clamps.
