Revision History Refer to each chapter for its own specific revision history. For information on when each chapter was updated, refer to the Chapter Revision Dates section, which appears in the complete handbook. Altera Corporation Section I.
Introduction Chapter 2. Cyclone II Architecture Chapter 3. Reference designs, system diagrams, and IP, found at www. The EP2C5A is only available in the automotive speed grade. Automotive-Grade Table 1—3. Altera Corporation February — — — — — — — — Updated Table v1. Mbps for outputs. LUT for unrelated functions. When using register packing, the LAB-wide synchronous load control signal is not available. Register Chain LEs in normal mode support packed registers and register feedback.
The Altera Corporation February Register feedback and register packing are supported when LEs are used in arithmetic mode. Figure 2—5 Figure 2—5. The LE directly supports an asynchronous clear function.
Each LAB supports up to two asynchronous clear signals labclr1 and labclr2. Cyclone II Device Handbook, Volume 1 Register chain interconnects within an LAB C4 interconnects traversing a distance of four blocks and down direction C16 interconnects for high-speed vertical routing through the device Figure 2—9 shows the register chain interconnects.
Altera Corporation February For LAB interconnection, a primary LAB or its LAB neighbor see interconnects can drive each other to extend their range as well as drive row interconnects for column-to-column connections.
Figure 2— 1 Each C4 interconnect can drive either up or down four rows. Table 2—1 Table 2—1. DPCLK pins are dual-purpose clock pins. Table 2—2. There are four clock control blocks on each side. Figures 2—11 and 2— Internal logic can be used to enabled or disabled the global clock network in user mode. IN Altera Corporation February IOE clocks are associated with row or column block regions. Only six global clock resources feed to these row and column regions. Table 2—3. The signal enables and disables the PLLs.
The pfdena signal controls the phase frequency detector PFD output with a programmable gate. If the C2 output is not Altera Corporation February The M4K memory blocks include input registers that synchronize Memory writes and output registers to pipeline designs and improve system performance. The output registers can be bypassed, but input registers cannot. This applies to both read and write operations. Memory initialization file. Altera Corporation February summarizes the features supported by the M4K memory.
Simultaneous read and write from an empty FIFO buffer is not supported. Description Altera Corporation February M4K block outputs can also connect to left and right LABs through each 16 direct link interconnects.
Altera Corporation February summarizes the different clock modes supported by the M4K Description In this mode, a separate clock is available for each port ports A and B The total number of multipliers for each device is not the sum of all the multipliers. Multiplier Modes Table 2—12 multipliers can operate in.
Table 2— R4 Interconnects Embedded Multiplier Control 36 [ The Quartus II software automatically duplicates a single OE register that controls multiple output or bidirectional pins. You can use IOEs as input, output, or bidirectional pins. There are two paths available for combinational or registered inputs to the logic array.
Each path contains a unique programmable delay chain. All registers share sclr and aclr, but each register can individually disable sclr and aclr. Programmable delays decrease input-pin-to-logic-array and IOE input register delays.
The Quartus II Compiler can program these delays to automatically minimize setup time while providing a zero hold time. The system clock is used to clock the DQS write signals, commands, and addresses.

When using on-chip series termination, programmable drive strength is not available. Changes Made 2— File via an embedded processor. Table 3—1. Manufacturer Identity 11 Bits and 3—3 show the 1, 1, 1, LSB 1 Bit Altera Corporation February Cyclone II devices are configured at system power-up with data stored in an Altera configuration device or provided by a system controller.
The bank CCIO selects whether the configuration inputs are 1. Hot-Socketing requirements. V planes. This condition can lead to latch-up and cause a low-impedance path from V a large amount of current, possibly causing electrical damage. CC parameters will determine the initialization time. July v2. February Removed ESD section. Altera Corporation February ramp time requirement, you must CC shows the revision history for this document.
Changes Made section. Additionally, device operation at the absolute maximum ratings for extended periods of time may have adverse effect on the device reliability. During transition, the inputs may undershoot to —2. This value is specified for normal device operation. The value may vary during power-up. This applies for all V settings 3. V ICM 3 The p — n waveform is a function of the positive channel p and the negative channel n.
Characteristics Table 5— Capacitance is sample-tested only. Capacitance is measured using time-domain reflectometry TDR. Refer to typical I standby specifications. Timing Specifications You should select power supplies and regulators that can supply the amount of current required when designing with Cyclone II devices. Table 5— The second row represents the minimum timing parameter for commercial devices.

Low-to-high transmission time. High-to-low transmission time. Lock time for high-speed transmitter and receiver PLLs. Refer to Figure 5—4 CO Figure 5—5. CO Figure 5—6.
