STMicroelectronics has announced the launch of first two logic devices in a new high-speed, radiation-hardened family that brings 150MHz+ performance to space applications.
The QML-V qualified RHFOSC04 (SMD15962F20207) integrated oscillator driver/divider and RHFAHC00 (SMD 5962F18202) quad NAND gate have more than twice the gate speed of typical rad-hard logic ICs to ensure faster response in high-frequency circuits.
Designed with ST’s proprietary 130nm CMOS technology already proven throughout the space industry, the new devices combine their speed advantage with low operating current and a best-in-class radiation hardness with an RHA (Radiation Hardness Assurance) qualified TID2 at 300 krad (Si) and immunity to SEL and SET3 up to 125 MeV.cm2/mg.
Their supply-voltage range of 1.8V-3.6V helps meet the tight power and energy restrictions typical on-board satellites and space vehicles.
The RHFOSC04 combines the roles of multiple discrete logic components to drive a crystal oscillator directly, which simplifies circuit design and enhances stability while saving board space and increasing system reliability. The divider adds flexibility by providing nominal-frequency, divide-by-2, divide-by-4, and divide-by-8 outputs.
The devices are available as bare die ready for System-in-Package (SiP) integration in customers’ applications or packaged as ceramic hermetic Flat 14 (RHFAHC00) and Flat 10 (RHFOSC04) devices.
