Matsushita Launches Power Management IC for the New Intel PXA210 and PXA250 Applications Processor; Small, Low Power Consumption Suitable for Portable Wireless Devices.Business/High Tech Editors OSAKA, Japan--(BUSINESS WIRE)--Feb. 12, 2002 Matsushita Electric Industrial Co., Ltd., known worldwide for its Panasonic brand of consumer electronics and digital communications Transmitting text, voice and video in binary form. See communications. products, announced today that it will launch a power management IC (Product Code: AN32500A) for portable wireless devices based on the Intel(R) PXA210 and Intel(R) PXA250 Applications Processor. The new IC, which only requires a low supply voltage and operates with a software controllable voltage management in accordance to CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. (1) performance, is slated for mass production in the 3rd Quarter of 2002. As the market for portable wireless devices such as PDAs(1) and cellular phones increases, so will the number of functions needed to satisfy customer demands for these products. There has been an increasing need for a power management IC that allows the CPU to operate at a low supply voltage and controls the power supply voltage in accordance to CPU performance, thereby decreasing total power consumption in the device. Matsushita has developed an IC with a low voltage Low voltage is an electrical engineering term that broadly identifies safety considerations of an electricity supply system based on the voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains circuit of +0.8V in the regulator, and by creating a new voltage control system to obtain a stable power supply. "The Intel PXA210 and PXA250 Applications Processor features industry-leading performance to support multimedia at the highest level, using less power. We appreciate that Panasonic will introduce the power management IC, a device which will benefit users through its small size and relatively low power consumption," commented Mark Casey, director of marketing for Intel's Handheld Computing Division. "Panasonic is committed to supporting a digital network society with key device technology. Our new power management IC will help expand applications of the new Intel PXA210 and PXA250 Applications Processor for advanced wireless devices," states Mr. Hideo Kawasaki, Director, Analogue LSI LSI: see integrated circuit. (Large Scale Integration) Between 3,000 and 100,000 transistors on a chip. See SSI, MSI, VLSI and ULSI. Division, Matsushita's semiconductor company. Matsushita plans to ship over 100,000 new IC's per month at a sample price of 500 yen. Features 1. High integration of power control circuits by built-in 4 channels regulators. For power control in the mobile information handsets with the Intel(R) PXA210/ PXA250 Applications Processor, 4 channels of power regulator circuits were integrated. Especially for the regulators except the boost-up channel, output transistors are embraced, which will help making those equipments smaller and lighter. 1 Channel: Power supply for CPU core Enables to setup output voltage from +0.8V to +1.3V. Output voltage can be set between +0.8 and +1.3V. Maximum output current is 300mA. 2 Channels: Power supply for memory and peripheral components Adjustable by external variable resistance from +1.8V to +3.3V Maximum output current is 300mA and 400mA for each. 1 Channel: boost-up converter Output voltage is +5V. Maximum output current is 500mA (OK) Software controllable voltage can be set via IIC See infranet. bus. As the power control on PDAs with Intel(R) PXA210/ PXA250 Applications Processor is performed by this power management IC, it contributes to reduce the power consumption and downsize Downsize Reducing the size of a company by eliminating workers and/or divisions within the company. Notes: When a company downsizes, it is attempting to find ways to improve efficiency and increase profitability. It is sometimes referred to as trimming the fat. the equipment. 2. Synchronous Refers to events that are synchronized, or coordinated, in time. For example, the interval between transmitting A and B is the same as between B and C, and completing the current operation before the next one is started are considered synchronous operations. Contrast with asynchronous. rectification rectification /rec·ti·fi·ca·tion/ (rek?ti-fi-ka´shun) 1. the act of making straight, pure, or correct. 2. redistillation of a liquid to purify it. system(3) achieved the low power consumption. By adopting the synchronous rectification system, high electric power conversion efficiency (4) is achieved. By combining with software controllable voltage management, it can contribute to low power consumption of mobile equipment greatly. Moreover, since the operation frequency is fixed, the measure against a noise can be performed easily. 3. Mounted in leadless and thin type package (HQFN) It is carried in the thin shape 64 pin HQFN package with 8.2mm2 size.

Glossary (1)CPU Central Processing Unit See CPU. (architecture, processor) central processing unit - (CPU, processor) The part of a computer which controls all the other parts. Designs vary widely but the CPU generally consists of the control unit, the arithmetic and logic unit (ALU), registers, temporary buffers , the central part of a computer which manages the data processing data processing or information processing, operations (e.g., handling, merging, sorting, and computing) performed upon data in accordance with strictly defined procedures, such as recording and summarizing the financial transactions of a , control, judgement, etc. Especially the device which constitutes CPU in a single LSI is called a microprocessor. (2)PDA (Personal Digital Assistant) A handheld computer for managing contacts, appointments and tasks. It typically includes a name and address database, calendar, to-do list and note taker, which are the functions in a personal information manager (see PIM). It is the abbreviation abbreviation, in writing, arbitrary shortening of a word, usually by cutting off letters from the end, as in U.S. and Gen. (General). Contraction serves the same purpose but is understood strictly to be the shortening of a word by cutting out letters in the middle, of Personal Digital Assistance, which has the function of personal information management such as own schedule, address book, TO DO lists and so on. Usually the palm-top electronic equipment which performs some of the major functions of personal computers.
