Chairman and Chief Executive Officer Christopher Galvin announced beginning of October that the company intends to separate its semiconductor operations into a publicly traded company. Motorola has not finalized details of the transaction but is considering an initial public offering (IPO) of a portion of SPS, followed by a distribution of remaining shares to shareholders in a tax-free manner, subject to Motorola board approval, favorable market conditions, regulatory approvals and other customary conditions.
To help improve the performance, efficiency and cost of future embedded applications, Motorola licensed StarCore LLC's portfolio of DSP cores and subsystems. Motorola plans to use StarCore's DSP technology as an integral part of future embedded system offerings targeted toward a variety of next-generation products that require efficient, high- performance processing capabilities.
Motorola has also extended it licensing agreement with ARM to include the ARM1136J-S™ core and the ARM1136JF-S™ core to create ARM1136™ core-based, feature-rich wireless devices. Motorola also announced that they will integrate the ARM926EJ-S™ core, incorporating ARM® Jazelle® Java acceleration technology, into their i.MX21 processor for mobile multimedia handheld devices.
Philips announced two new members of its high performance, low cost ARM-based microcontroller (MCU) family, the new LPC2114 and LPC2124. Key features of the devices include up to 256K bytes of embedded Flash memory, 10-bit A/D converters, 16K of SRAM, pulse width modulation (PWM) timers, UARTS, serial peripheral interface (SPI) and up to 46 General-Purpose Input/Outputs in a small outline 64-pin package.
The LPC21xx family uses a 0.18-micron CMOS embedded Flash process enabling 1.8V voltage operation. The new devices operate at 60MHz (54 Dhrystone MIPs) and offer 128-bit wide zero wait-state Flash memory.
Philips announced a new TriMedia™ Central Processing Unit (CPU) core to be used in the next-generation of Philips' Nexperia™ media processors. Philips' new super-pipelined TriMedia CPU achieves over 500 Megahertz (MHz) speed with a fully synthesizable design. Philips is targeting its next-generation of media processors for connected home entertainment applications, including connected high-definition (HD) displays, home media servers, personal video recorders (PVRs) and video over wireless 802.11 network adaptors.
The TriMedia CPU is C-programmable and can support all leading audio and video standards, including MPEG-2, MPEG-4, DV, H.263, and DivX-5. New instructions specifically optimize H.264 decoding. It supports video encoding into MPEG-2, MPEG-4, and DivX formats, making it ideal for PVRs. The ability to transcode from one video format to another supports the design of media gateway products. Furthermore, HDTV decoding with simultaneous picture-in-picture (PIP) display is enabled using a dedicated HD accelerator. Uniquely, the TriMedia CPU can decode HDTV video while simultaneously encoding an MPEG stream. This allows the design of the HDTV displays with Flash card-based PVR capability.
Philips announced two new series of I˛C General Purpose I/O expanders (PCA953x and PCA955x) optimized for controlling LED dimming and blinking. These new 2, 4, 8 and 16 bit devices represent an innovation in I˛C capabilities, allowing designers an easier way to build systems with more dimming or blinking LEDs than previously possible using just basic General Purpose I/Os (GPIO) or microcontrollers (MCUs).
The PCA953x LED Dimmers have a frequency range of 160 Hz to once every 1.6 seconds, with a duty cycle range of completely off to 99.4pct on allowing both dimming and blinking of LEDs. The PCA955x LED Blinkers have a frequency range of 40 Hz to once every 6.4 seconds with a duty cycle range of 0.6pct off to completely on, that allows designers to set, for example, a 4 second blink rate with the LED on for 1 second and then off for 3 seconds. Output drive strength is 25 mA per bit at 5 V operation and 100 mA for 8 bit groups, which is much more than the amount of current typically allowed by a MCU. The devices operate between 2.3 V and 5.5 V and up to a 400 kHz I˛C bus speed. Any I/O pins not used as outputs can be configured and used as normal general-purpose inputs.
The 8-pin PCA9550 2-bit LED Blinker, 16-pin PCA9551 8-bit LED Blinker, 24-pin PCA9552 16-bit LED Blinker/PCA9532 16-bit LED Dimmer and 8-pin PCA9553 4-bit LED Blinker are available now. The 8-pin PCA9530 2-bit LED Dimmer, 16-pin PCA9531 8-bit LED Dimmer and 8-pin PCA9533 4-bit LED Dimmer are sampling now with releases through the end of the year.
