• STMicroelectronics’ high-performance logic devices provide faster response in high-frequency circuits
  
• Supply-voltage range of 1.8V-3.6V helps meet the tight power and energy restrictions of onboard satellites and space vehicles

STMicroelectronics has introduced two new logic devices in a high-speed, radiation-hardened family that brings 150MHz+ performance to space applications.

The QML-V qualified RHFOSC04 (SMD 5962F20207) integrated oscillator driver/divider and RHFAHC00 (SMD 5962F18202) quad NAND gate have more than twice the gate speed of typical rad-hard logic ICs, ensuring faster response in high-frequency circuits.

Designed using 130nm CMOS technology, the new devices combine their speed with low operating current and best-in-class radiation hardness with a Radiation Hardness Assurance (RHA) qualified Total Ionising Dose (TID) at 300 krad (Si) and immunity to SEL and SET up to 125 MeV.cm2/mg.

Their supply-voltage range of 1.8V-3.6V helps meet the tight power and energy restrictions that are typical of onboard satellites and space vehicles.

The RHFOSC04 combines multiple discrete logic component functionalities to directly drive a crystal oscillator, 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.
