8 / 17 page Fusion Device Family Overview 1- 4 Prel i minary v0 .4 Advanced Flash Technology The Fusion family offers many benefits, including nonvolatility and reprogrammability through an advanced flash-based, 130-nm LVCMOS process with seven layers of metal. Standard CMOS design techniques are used to implement logic and control functions. The combination of fine granularity, enhanced flexible routing resources, and abundant flash switches allows very high logic utilization (much higher than competing SRAM technologies) without compromising device routability or performance. Logic functions within the device are interconnected through a four-level routing hierarchy. Advanced Architecture The proprietary Fusion architecture provides granularity comparable to standard-cell ASICs. The Fusion device consists of several distinct and programmable architectural features, including the following (Figure 1-1 on page 1-6): • Embedded memories – Flash memory blocks –FlashROM – SRAM and FIFO • Clocking resources – PLL and CCC – RC oscillator – Crystal oscillator – No-Glitch MUX (NGMUX) • Digital I/Os with advanced I/O standards • FPGA VersaTiles • Analog components – ADC – Analog I/Os supporting voltage, current, and temperature monitoring – 1.5 V on-board voltage regulator – Real-time counter The FPGA core consists of a sea of VersaTiles. Each VersaTile can be configured as a three-input logic lookup table (LUT) equivalent or a D-flip-flop or latch (with or without enable) by programming the appropriate flash switch interconnections. This versatility allows efficient use of the FPGA fabric. The VersaTile capability is unique to the Actel families of flash-based FPGAs. VersaTiles and larger functions are connected with any of the four levels of routing hierarchy. Flash switches are distributed throughout the device to provide nonvolatile, reconfigurable interconnect programming. Maximum core utilization is possible for virtually any design. In addition, extensive on-chip programming circuitry allows for rapid (3.3 V) single-voltage programming of Fusion devices via an IEEE 1532 JTAG interface. |
