Sharp's next-generation high-performance 32bit smart card incorporates 1Mbyte of Flash memory.
Faster access for high-density Flash
Sharp Microelectronics Europe reckons its latest high-speed 128Mbit Flash memory features the fastest access time available to date.
High speed is ensured by the latest generation of high speed LEDs with Sharp CMOS driver ICs and Sharp OPIC and BiCMOS components.
Using Sharp's OPIC technology, the integration of the photodiode and the signal processing ICs on a single chip enables cost-efficient production.
High-speed photocouplers are used in factory automation environments, fieldbus applications like Device Net, Profibus and Interbus and in computer data network interfaces, such as RS422 or PS485.
The new components demonstrate outstanding insulation, noise immunity and reliable serial transmission.
The photocouplers' high insulation voltage of up to 3.75kV and high moisture and heat resistance are made possible by Sharp's patented double transfer mould technology, in which the photocells are enveloped with a transparent and a nontransparent high-temperature-resistant epoxy resin of the same basic material in a two-step process.
As the thermal expansion coefficients of the materials employed are identical, the photocouplers are not mechanically sensitive to heating.
Depending on specification, the new high-speed photocouplers work within a temperature range of between -55 and +100C.
In addition, the double transfer mould technology also enables the components to withstand the peak temperatures of 260C to which they are exposed during the reflow and dip soldering processes.
Sharp's high-speed photocouplers comply with worldwide safety standards such as UL, VDE and DIN/EN60747-5-2.
As far as ISO14001 environmental management certification and the RoHS Directive are concerned, Sharp is already offering lead-free versions of these products.
Various package options are available: SOP4/5/8, DIP4/6/8 and a half-pitch package.
The PC412S0NIP0F high speed photocoupler with a transfer rate of 25Mbit/s as well as all the other new photocoupler models are available now.
Photocouplers for temperature ranges from -55 to +100C as well as a 3.3V series will be available from Q3 2005.
