1.2. Features
EPCQ devices offer the following features:
• Serial or quad-serial FPGA configuration in devices that support active serial (AS)
x1 or AS x4 configuration schemes
(2)
• Low cost, low pin count, and non-volatile memory
• 2.7-V to 3.6-V operation
• Available in 8- or 16- small-outline integrated circuit (SOIC) package
• Reprogrammable memory with up to 100,000 erase or program cycles
• Write protection support for memory sectors using status register bits
• Fast read, extended dual input fast read, and extended quad input fast read of the
entire memory using a single operation code
• Write bytes, extended dual input fast write bytes, and extended quad input fast
write bytes of the entire memory using a single operation code
• Reprogrammable with an external microprocessor using the SRunner software
driver
• In-system programming (ISP) support with the SRunner software driver
• ISP support with Intel FPGA Download CableIntel FPGA Download Cable II, Intel
FPGA Ethernet Cable
•
By default, the memory array is erased and the bits are set to 1
• More than 20 years data retention
