L7205 Product Brief
Internet System ProcessorDSP Enhanced
Target Market
L7205 targeted emerging Internet/Information appliance markets. This "system-on-silicon" device delivers high performance, power, highly integrated, cost system solutions. L7205 ideally suited Information/Internet appliances; such wireless Internet terminals, smart phones, Pocket PCs, Webpads, screen phones, low-cost boxes, terminals. L7205 provides easy upgrade path from L7200 maintaining register compatibility.
Architecture
L7205 designed provide highest system performance lowest power dissipation. Separate data busses instruction access (from ROM/Flash) data access (from DRAM) permit on-chip operate highest efficiency without waiting screen refresh cycles. Data transfer operations with DMA-backed on-chip peripherals require minimal intervention, provide high throughput, and, same time, save power. device's architecture permits design very cost systems. example, minimum system built with just SDRAM MultiMediaCard(flash card), without using ROMs.

Overview
L7205 system-on-silicon chip designed provide high performance, low-power solution cost-sensitive applications; such Pocket PCs, smart phones, wireless Internet terminals, Web-pads, screen phones, low-cost box, terminal. L7205 includes on-chip ARM720Tcore with PiccoloDSP coprocessor. ARM720Twith coprocessor RISC with ARM®'s instruction extensions provide high code density required cost consumer products. employs Kbytes on-chip unified cache, write buffer, with 64-entry buffer. core includes engine with instruction cache (512Byte) applications such soft modem, decode, speech compression, JPEG compression other real time applications. chip block diagram above shows major subsystems integrated chip. memory subsystem consists high performance SDRAM controller separate Static Memory Controller. separating SDRAM controller from Static Memory Controller, bandwidth bottleneck, typically present single systems, removed. Thus does have contend with LCDC available memory bandwidth when executing ROM/Flash. separate control subsystems provided. mono controller provides shades gray capable using on-chip SRAM frame buffer power designs. color controller supports larger DSTN panels color, which used mono mode cost systems, well panels more upscale products; such desktop screen phones. L7205 versatility evident support many popular interfaces target market. These interfaces include Motorola SPI/National MicrowireTM, MultiMediaCardTM, Card v2.0, CompactFlashUSB (v1.1), IrDA, Bluetooth-ready UARTs, ACLink (v2.1) LSB/MSB justified serial data interface with many popular audio codecs. addition, chip supports Philips UCB1200 (Modem-Audio-Analog front-end) provide modem audio functions, along with touch screen interface. UART channels allow modem interface wireless communication (IrDA) respectively. support peripheral devices provides fast data transfers even while stopped conserve power. Five power states extensive power management enable design long-life battery-based products.
L7205SDB Features
