Altera® MAX® 9000 7000S in-system programmable devices offer designers flexibility, advanced features, high performance price. Combining these features with most complete development tools environment offers designers best solution their design needs. This technical brief focuses programming time, performance, size, power consumption advantages 9000 7000S devices. When choosing in-system programmable device, important evaluate complete solution. effort show benefits 9000 7000S devices, Altera Applications recently compared several aspects Altera Xilinx in-system programmable device families. Programming Times Altera 9000 7000S devices programmed quickly both production development environments. contrast, device programming times Xilinx XC9500 devices times higher development environments than production environments. According Xilinx Application Note XAPP068 In-System Programming Times, this increase overhead spent real-time generation programming vectors from JEDEC bitmap, bandwidth limitations outputting JTAG vectors, time required erase device. Table shows in-system programming times Xilinx XC9500 Altera 7000S devices with comparable densities. Table 7000S XC9500 In-System Programming Times

Size Altera aggressively pursues most advanced manufacturing processes, enabling designers benefit from highest performance devices lowest price. example, Altera migrated 128-macrocell device offerings from 0.8-micron, dual-layer metal process 1992, 0.5-micron, triple-layer metal process 1997. Migrations allow Altera continue providing extremely competitive prices. contrast, Xilinx XC9500 device family manufactured 0.6-micron, dual-layer metal process. Figure compares sizes XC95108, EPM7128E, EPM7128S devices.

addition, Altera plans manufacture next-generation product-term based family, Michelangelo, 0.35-micron, quad-layer metal process beginning early 1998. Thus, Altera continues aggressively pursue most efficient manufacturing process. Power Consumption Altera 7000S device family offers power-efficient interconnect structure. fact, 7000S devices consume less power than XC9500 devices when operating under similar conditions (see Figure Figure 7000S XC9500 Power Consumption
