ISL 7202 x. SEH (legacy): RH 3. 3 V CAN Bus Transceiver Family 26 • LBK Logic Input (Pin 5): ISL 72026 SEH – When a “HIGH” level is applied at the LBK pin, the device enters the loopback state. – The transceiver CANH and CANL pins are disconnected from the bus. 27 & 28 – The driver and receiver circuitry of the transceiver remains active for diagnostic testing of the node (ECU). • VREF Output (Pin 5) for Split Termination: ISL 72027 SEH & ISL 72028 SEH – Provides a VCC / 2 output voltage for split mode termination. – Split mode termination technique is shown below. It is used to stabilize the bus voltage at VCC / 2 and prevent if from drifting to high common-mode voltage during periods of inactivity. The technique improves the electromagnetic compatibility of a network. – Split mode termination is put at each end of the bus. – CL capacitor filters unwanted high frequency noise to ground. The capacitance value used is dependent on the signaling rate of the network. A typical value used for a 1 Mbps CAN network is 4. 7 n. F, which generates a 3 d. B point at 1. 1 Mbps. 6 June 2017 Intersil Confidential Information

Intersil Radiation Tolerant Plastic Products Initiative Powering the Next Generation of Satellite Constellations
Introduction • Current Industry Trends and Needs – Innovation in space is being driven more by private industry giving rise to “the business of space” – Emergence of mega-constellations by the use of “small–sats” in low earth orbits • Space. X, One. Web, and Google the most notable examples – Reduce cost to drive reasonable profitability • Industry Solution – Migrating from traditional radiation hardened microcircuits to commercial off the shelf (COTS) • Reduce cost, increase capability by access of modern technology, decrease size (SWa. P) • Industry Misconception – Limited issues will be encountered when qualifying and operating COTS devices in what is commonly thought of to be a benign low earth orbit (LEO) space environment. 13 June 2017 Intersil Confidential Information
Program Profile for Next Generation Satellite Constellations • Program Profile – Expected Life Cycle ≤ 5 years • Satellites will be replaced with system upgrades – Total radiation exposure = 10 - 30 krad(Si) • Margin may be needed, devices may need to meet as high as 60 krad(Si) – SEE expectations = LET of 30 – 43 Me. V∙cm 2/mg • Non-destructive SEE can be typically handled with redundancy, EDAC, filtering, etc. – Adds system level design complexity and cost – May not even be fully effective • Destructive SEE causes early termination of satellite life cycle 14 June 2017 Intersil Confidential Information
The Need for Radiation Tolerant ICs in Next Generation Constellation • Cost – Using COTS devices require up-screening before they are found suitable for space applications • The most notable tests include total ionizing dose (TID), possibly both high dose rate and low dose rate, and Single Events Effects testing. • This testing is very expensive and what seemed a less expensive alternative can end up costing more. • Risk – Radiation testing and characterization of a device today does not indicate the next lot will work • Variations in fabrication or even a change in location can affect performance with regards to radiation tolerance. These changes are often not communicated to the customer as it does not affect the electrical performance of the device. • Reliability – NASA has published reports indicating that a large percentage of “small-sats” are dead on June 2017 or cease operation much before Intersil Confidential Informationlife. Using more reliable devices suited 15 arrival the expected
Radiation Tolerant Plastic Product Line Qualification Criteria • One time characterization to 30 krad(Si) at a dose rate of ≤ 10 mrad/sec. • SEE characterization for destructive and transient events • 2 lot temperature characterization to -55 C and +125 C – To set datasheet limits • Automotive “like” qualification – – – – 16 2000 hours of life test Moisture resistance test (MRT) 500 Temperature Cycles (-55 C to +125 C) Unbiased HAST Biased HAST 1000 hour Storage life +125 C latch-up and ESD Surface mount leaded packages with Ni.
