EPC16QC100N Ringkasan

The Altera EPC16QC100N is a 16-Mbit in-system programmable configuration PROM designed to store configuration bitstreams for SRAM-based Altera FPGAs including the ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone, Cyclone II, FLEX 10K, FLEX 6000, Mercury, Stratix, Stratix GX, Stratix II, and Stratix II GX families. Housed in a 100-pin Plastic Quad Flat Pack (QFP) measuring 20x14 mm, the device operates from a single 3.0 V to 3.6 V supply and supports a maximum configuration clock frequency of 33 MHz.

What is an FPGA configuration PROM? An FPGA configuration PROM is a non-volatile flash memory device that stores the bitstream (configuration data) for SRAM-based FPGAs. Because SRAM loses its configuration when power is removed, an external non-volatile store is required to reload the device at every power-up. These configuration PROMs sit in the hierarchy as follows: configuration PROM -> serial/parallel flash memory -> non-volatile memory -> memory IC -> integrated circuit (semiconductor). They expose a dedicated configuration interface (DATA, DCLK, nCONFIG, nSTATUS, CONF_DONE) that handshakes directly with the FPGA during the load sequence.

Key features include 16,777,216 bits of flash memory (16 Mbit), on-chip decompression that supports compressed bitstreams up to twice the memory density, and a fast page-mode configuration interface. The device supports JTAG-based in-system programming via IEEE Std 1149.1, allowing the configuration image to be updated on a populated PCB without removing the PROM. Operating temperature is specified for the commercial 0C to 70C range.

The EPC16QC100N uses a flash-based architecture with a typical 90 ns access time, providing approximately 10 MHz flash read bandwidth. The 16-bit DQ flash data bus delivers up to 160 Mbps of bandwidth, which is more than sufficient for legacy Altera configuration schemes but lower than what modern Stratix FPP (Fast Passive Parallel) modes require at high clock rates.

Typical applications include FPGA configuration storage on industrial control boards, telecommunications line cards using Stratix or Cyclone devices, test and measurement chassis that require in-field bitstream updates, and legacy designs that pair ACEX 1K or APEX 20K devices with a parallel configuration PROM. The wide 3.0V to 3.6V supply range also suits +3.3V system rails common in telecom infrastructure.

When designing with this device, ensure that the configuration mode of the target FPGA is compatible with the EPC16QI100N's supported modes (FPP, PS, AS). The nINIT_CONF pin allows the FPGA to delay configuration start; leave it pulled high through a 10 kohm resistor if unused. Verify that the bitstream fits in 8 Mbit uncompressed or 16 Mbit compressed.
