Table 4–25. Timing Parameters for AS Configuration (Part 2 of 2)
Existing batches of EPCS1 and EPCS4 manufactured on 0.15 µm process geometry supports AS configuration up
to 40 MHz. However, batches of EPCS1 and EPCS4 manufactured on 0.18 µm process geometry support only up
to 20 MHz. EPCS16, EPCS64, and EPCS128 are not affected. For information about product traceability and
transition date to differentiate between 0.15 µm process geometry and 0.18 µm process geometry EPCS1 and
EPCS4, refer to PCN 0514 Manufacturing Changes on EPCS Family process change notification on the Altera
website at www.altera.com.

The Quartus II design software provides programming support for serial
configuration devices. After selecting the serial configuration device, the
Quartus II software automatically generates the Programmer Object File
(.pof) to program the device. The software allows users to select the
appropriate serial configuration device density that most efficiently
stores the configuration data for a selected FPGA.
The serial configuration device can be programmed in-system by an
external microprocessor using SRunner. SRunner is a software driver
developed for embedded serial configuration device programming that
designers can customize to fit in different embedded systems. The
SRunner can read RPD file and write to the serial configuration devices.
The programming time is comparable to the Quartus II software
programming time. Note that writing and reading the RPD file to the
EPCS is different from other data and address bytes. The LSB of RPD
bytes must be shifted out first during the read bytes instruction and the
LSB of RPD bytes must be shifted in first during the write bytes
instruction. This is because the FPGA reads the LSB of the RPD data first
during the configuration process.
For more information about SRunner, refer to
Embedded Solution for Serial Configuration Device Programming User Guide
and the source code on the Altera website (www.altera.com).
Serial configuration devices can be programmed using the APU with the
appropriate programming adapter (PLMSEPC-8) via the Quartus II
software, USB Blaster, EthernetBlaster, or the ByteBlaster II download
cable via the Quartus II software. In addition, many third-party
programmers, such as BP Microsystems and System General, offer
programming hardware that supports serial configuration devices.
