Philips Semiconductors Introduces One Chip PDA, A Single Chip Embedded Processor For LCD Handheld Devices; One Chip PDA Provides Superior Integration in a Modular Solution for PDA Applications.SUNNYVALE, Calif.--(BUSINESS WIRE)--Nov. 27, 1995--Philips Semiconductors today unveiled its One Chip 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). , a single-chip highly-integrated solution designed specifically for LCD-based handheld devices. Based on the powerful MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. R3000 core - a full 32-bit RISC processor - the new device features high processor performance, the highest level of system integration available today, low power consumption, and minimal external components requirements. The One Chip PDA is expected to be the preferred choice for consumer handheld devices where price, size, power consumption and performance play important roles. The One Chip PDA is designed for portable handheld devices with LCD screens accessed either by direct touch or by keyboard. Applications particularly well-suited for the embedded processor are PDAs, smart telephones, organizers, handheld games, electronic books, and data collection devices. Although created for LCD handheld devices, the One Chip PDA is equally adaptable to other products where a highly-integrated, low power, cost-effective processor is required. Unique to the One Chip PDA is a modular design philosophy that provides for a cost-effective migration path to next-generation Philips Semiconductors embedded processors. Modules currently on the One Chip PDA include: LCD and Video Modules - Features bit-mapped graphics; support for multiples screen sizes, a main-memory resident video buffer with DMA (1) (Digital Media Adapter) See digital media hub. (2) (Document Management Alliance) A specification that provides a common interface for accessing and searching document databases. data transfers; monochrome 4- or 8-level gray, or 8-bit color modes; time-based dithering Simulating more colors and shades in a palette. In a monochrome system that displays or prints only black and white, shades of grays can be simulated by creating varying patterns of black dots. This is how halftones are created in a monochrome printer. algorithm; and support for 4-bit or 8-bit split and non-split screens. Touch-Screen Module - Utilizes a 10-bit ADC (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. to digitize touch-screen measurements and allows for measurements of position. Not only can the processor be interrupted when touch is sensed, but a unique approach to analog multiplexing allows measurements of other analog signal levels (e.g. battery level). Sound Generation Module - An 8-bit DAC See D/A converter and discretionary access control. DAC - Digital to Analog Converter with built-in amplifier for direct connection to speakers. Allows the generation of a single tone of programmable frequency, amplitude and duration; allows for digital to analog conversion of sound samples stored in memory. Realtime Module - Clock generation from a 32.768 KHz XTAL XTAL Crystal XTAL External ; 48-bit counter for permanent date and time; 48-bit alarm register; 16-bit periodic timer; interrupts on alarm each one second and periodic timer. RC5, RC6/lrDA Compatible Infrared Module - Compatible with the consumer electronic protocols (transmit and receive such as Philips RC5/RC6). Also compatible with the new lrDA high-speed infrared protocol. Provides for up to 1000 bits/sec at 10M using consumer mode, and up to 115 Kbits/sec at 1M using lrDA. High-Speed UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice - A basic serial communications channel - provides full-duplex UART; programmable baud-rate and DMA support for receive or transmit. The One Chip PDA provides an analog on-chip reference for all modules, and contains an 8-bit DAC used to generate analog voltages for general purpose usage. Packaged in a 160-pin Low Profile Quad Flat Pack (LQFP See QFP. ), the 3.3V device features fully static CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology. All peripheral modules can be individually powered down (running, dozing, sleeping, and coma). According to Cees Hartgring, Philips Semiconductors' general manager of Communication Multimedia Group, "The OneChipPDA modular approach allows for functional units to be replaced, modified, or redesigned in the future to provide next-generation capabilities to our customers. The superior integration of this product is unique - its functionality, flexibility, and low-power requirements, all at a low cost, represent an important breakthrough by Philips." Samples of the One Chip PDA will be available in January 1996, with production scheduled for Q2. Pricing will be under $20.00 each in quantities of 100,000.
