The Stratix? III family provides one of the most architecturally advanced,high-performance, low-power FPGAs in the marketplace.Stratix III FPGAs lower power consumption through Altera’s innovative Programmable Power Technology, EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780 which provides the ability to turn on the performance where needed and turn down the power consumption for blocks not in use. Selectable Core Voltage and the latest in silicon process optimizations are also employed to deliver the industry’s lowest power, high-performance FPGAs.Specifically designed for ease of use and rapid system integration, the Stratix III FPGA family offers two variants optimized to meet different application needs: EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780
■ The Stratix III L family provides balanced logic, memory, and multiplier ratios for mainstream applications. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780
■ The Stratix III E family is memory- and multiplier-rich for data-centric applications. Modular I/O banks with a common bank structure for vertical migration lend efficiency and flexibility to the high-speed I/O. Package and die enhancements with dynamic on-chip termination, output delay, and current strength control provide best-in-class signal integrity. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780 Based on a 1.1-V, 65-nm all-layer copper SRAM process, the Stratix III family is a programmable alternative to custom ASICs and programmable processors for high-performance logic, digital signal processing (DSP), and embedded designs.Stratix III devices include optional configuration bit stream security through volatile or non-volatile 256-bit Advanced Encryption Standard (AES) encryption. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780 Where ultra-high reliability is required, Stratix III devices include automatic error detection circuitry to detect data corruption by soft errors in the configuration random-access memory (CRAM) and user memory cells.

Electrical Characteristics
This chapter describes the electrical characteristics, switching characteristics, and I/O timing for Stratix? III devices. Electrical characteristics include operating conditions and power consumption. Switching characteristics include core performance specifications and periphery performance. A glossary is also included for your reference. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780
Operating Conditions
When Stratix III devices are implemented in a system, they are rated according to a set of defined parameters. To maintain the highest possible performance and reliability of Stratix III devices, system designers must consider the operating requirements described in this chapter. Stratix III devices are offered in both commercial and industrial grades. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780 Commercial devices are offered in –2 (fastest), –3, –4, and –4L speed grades. Industrial devices are offered only in –3, –4, and –4L speed grades. 1 In this chapter, a prefix associated with the operating temperature range is attached to the speed grades; commercial with a “C” prefix and industrial with an “I” prefix. For example, commercial devices are indicated as C2, C3, C4, and C4L per respective speed grades. Industrial devices are indicated as I3, I4, and I4L.

Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for Stratix III devices. The values are based on experiments conducted with the device and theoretical modeling of breakdown and damage mechanisms. The functional operation of the device is not implied at these conditions. Conditions beyond those listed in Table 1–1 may cause permanent damage to the device. Additionally, device operation at the absolute maximum ratings for extended periods may have adverse effects on the device. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780
All Stratix III devices support vertical migration within the same package (for example, you can migrate between the EP3SL50 and EP3SL70 devices in the 780-pin FineLine BGA package). Vertical migration allows you to migrate to devices whose dedicated pins, configuration pins, and power pins are the same for a given package across device densities. To ensure that a board layout supports migratable densities within one package offering, enable the applicable vertical migration path within the Quartus? II software.

This minimizes the cost of vertical migration. lists the Stratix III FineLine BGA (FBGA) package sizes. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780
Stratix III devices are hot-socketing compliant. Hot socketing is also known as hot plug-in or hot swap, and power sequencing support without the use of any external devices. Robust on-chip hot-socketing and power-sequencing support ensures proper device operation independent of the power-up sequence. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780 You can insert or remove a Stratix III board in a system during system operation without causing undesirable effects to the running system bus or the board that was inserted into the system. The hot-socketing feature makes it easier to use Stratix III devices on PCBs that also contain a mixture of 3.3-V, 3.0-V, 2.5-V, 1.8-V, 1.5-V, and 1.2-V devices. With the Stratix III hot socketing feature, you do not need to ensure a specific power-up sequence for each device on the board. EP3SL70F780C3N Altera IC Stratix III Logic 70K FBGA780
