Timing Information
Serial Configuration (EPCS) Devices Datasheet
January 2014
Altera Corporation
Figure 19 shows the timing waveform for the read operation of the EPCS device.
Table 17 lists the EPCS device timing parameters for the read operation.
1 Existing batches of EPCS1 and EPCS4 devices manufactured on 0.15 m process
geometry support the AS configuration up to 40 MHz. However, batches of EPCS1
and EPCS4 devices manufactured on 0.18 m process geometry support the AS
configuration only up to 20 MHz. EPCS16, EPCS64, and EPCS128 devices are not
affected.
f For more information about product traceability and transition date to differentiate
between 0.15 m process geometry and 0.18 m process geometry of the EPCS1 and
