Spear-1310 - Dual Cortex-A9 for embedded applications 

ST,Cortex-A9

"The new microprocessor combines the unrivalled low power and multi-processing capabilities of the ARM Cortex-A9 processor core with innovative Network-on-Chip (NoC) technology. The dual ARM Cortex-A9 processors support both fully symmetric and asymmetric operations, at speeds of 600MHz/core (industrial worst-case conditions) for 3000 DMIPS equivalent. NoC is a flexible communications architecture that enables multiple different traffic profiles while maximizing data throughput in the most performance- and power-efficient way."

The evolution of phase-change memory

The evolution of phase-change memory

"Phase-change memory (PCM) is a term used to describe a class of nonvolatile memory devices that exploit the ability of certain materials to rapidly change phase between two stable physical states. Phase-change memory blends the attributes commonly associated with NOR-type flash memory, NAND-type flash memory, EEPROM memory, and DRAM (Figure 1) and is a leading candidate for the next generation of nonvolatile memory (NVM), expanding the use of NVM in computing and storage systems. As traditional electron storage-based memories such as NOR and NAND flash begin to encounter scaling difficulties, PCM is considered to be the best candidate to continue the scaling of NVM."

DC-voltage doubler reaches 96% power efficiency

DC-voltage doubler reaches 96% power efficiency

Design Idea, ADG888, AD8617

"The voltage-doubler circuit in Figure 1 can convert 2.5V dc to 5V dc or 1.8V to 3.3V. Most voltage doublers use an inductor, but this circuit doesn't need one. The circuit uses a capacitor, C, by charging it through serially connected switches. The charge switches let capacitor C charge, and the discharge switches are open. In the subsequent discharging phase, the charge switches are off, and the discharge switches close. The two discharge switches now connect capacitor C between the source of the input voltage, VS, and the output capacitor, COUT. This connection scheme lets the applied voltages combine. Thus, the voltage at the output terminal has a value close to 2VS."

Making mobile chips – a sneak peek at wafer manufacturing

GlobalFoundries, ARM

"The process of making a wafer can take two to three months and involves a number of steps including film deposition (Oxidation, DCVD & PVD), chemical mechanical polishing (CMP), photolithography, etching, cleaning technology, implantation and diffusion. Each of these is a process in and of itself, and can be repeated several times in fixed order."

Need intelligent power solution?

IDT offers P95020 with an impressive list of system power regulation and management functions integrated on a single chip, including:

General purpose MCU, Li-Ion/Li-Poly charger, Buck and Boost DC-DC converters,  three 150mA LDOs, four 50mA LDOs , always-on 10mA  LDO, Class D amplifier, 4 channel CODEC, Touch Screen Controller, Real Time Clock and I2C interface.

MCU is  a bit of mystery though and does not seem to be any of the Cortex-M type.
