Differences Between Stratix IV and HardCopy IV Devices
■ The HardCopy IV device family supports full high-speed differential I/O and
DPA mapping from the Stratix IV family. Both families are designed with identical
dedicated circuitry and thus support the same I/O standard, implementation
guidelines, and performance.The HardCopy IV family does not offer a 1760-pin
package.
■ The Stratix IV E 780-pin package offers 56 Rx + 56 Tx or 112 eTX channels, while
the HC4E25W 780-pin wire-bond packages offer 48Rx+48Tx channels on the row
(left and right) I/O banks.
■ The Stratix IV E 780-pin package offers 64 Rx + 64 eTx or 128 eTx channels, while
the HC4E25W 780-pin wire-bond packages offer 24 Rx + 24 eTx or 48 eTx channels
on the column (top and bottom) I/O banks.
■ The HardCopy IV E 1517-pin package offers 88Rx+88Tx channels, while the
EP4SE530 and EP4SE820 1517-pin packages offer 112 Rx + 112 Tx or 224 eTx
channels on the row (left and right) I/O banks.
