MoSys, Inc. announced that the company's 1T-SRAM memory technology has now been silicon-proven on a 90-nanometer standard logic process. The 1T-SRAM memory uses a 0.61-micron square-bit cell design for an embedded memory density of 1.1 mm square per megabit. The company says this allows designers to integrate over 100-megabits of embedded memory on a standard logic device for SoC products, and that by incorporating MoSys' Transparent Error Correction (TEC) technology as standard for the 90-nanometer implementation of 1T-SRAM memory, the user avoids the cost of laser repair for large embedded memories while maintaining adequate yield, reliability, and low soft error rate. The measured soft error rate for 1T-SRAM test chips on the 90-nanometer process is under 4 Failure-In-Times (FITs) per megabit.
Motorola, Inc.'s Semiconductor Products Sector, announced a flexible IO expansion IC for microcontroller-based systems. The company says the MC33993 combines “flexible input and output features” and may eliminate the need for dozens of discrete and standard linear ICs in a design. Motorola also says that “in many systems, it may be the only device needed besides the MCU and a 3-pin regulator.” The MC33993 interfaces with a MCU through a four-pin serial peripheral interface and uses an analog multiplex feature to send up to 22 analog signals to one MCU A/D input. The 22 IO pins may be configured to detect the status of a switch contact, provide an analog value to a buffered output, drive an LED or the gate of an FET, or provide switched power to a low current sensor. The MC33993 also includes a low-current sleep mode.
National Semiconductor announced the LP387x family of low-noise CMOS low dropout (LDO) switching regulators for low voltage, high current applications. The six new products have output currents of 0.8 A, 1.5 A or 3.0 A, logic-controlled ON/OFF, either an error flag or a separate sense pin, and over-temperature and over-current protection. The typical dropout voltage for the regulators is a low 240 mV at 800 mA, 380 mV at 1.5 A, and 800 mV at 3.0 A load. The new product family includes the LP3871, LP3872, LP3873, LP3874, LP3875, and LP3876, and is characterized by an output voltage accuracy of +/- 1.5% at room temperature over load and line variations, and is guaranteed to be +/- 3.0% over all conditions. In applications where the load is remote from the regulator, the separate output sense pin allows sensing at the load, compensating for PCB trace resistance. The 10 nA quiescent current in shutdown mode permits Sleep or Standby operation. The LP387x family is currently available.
