EPC144TC32

EPC144TC32 - Altera 440kb OTP Configuration PROM | 32-TQFP

The Altera (now Intel FPGA) EPC144TC32 is a one-time programmable (OTP) configuration memory device designed to store FPGA configuration bitstreams, providing 440,800 bits of storage in a 32-pin TQFP (7x7 mm) surface-mount package. It belongs to Altera's classic EPC family of serial configuration PROMs that were widely used with early Altera FLEX, ACEX, APEX, Cyclone, and Stratix series FPGAs. A configuration PROM (programmable read-only memory) is a non-volatile serial memory device that holds the FPGA's bitstream and serially configures the FPGA at power-on via a dedicated configuration interface. The EPC1xx family follows the hierarchy: configuration PROM -> serial memory -> non-volatile memory -> programmable logic support device. These devices replace EPROM/EEPROM-based configuration solutions and streamline FPGA boot logic by integrating the configuration controller, oscillator, and bitstream storage in a single chip. Key features of the EPC144TC32 include 440,800-bit storage capacity (sufficient for mid-density Altera FPGA bitstreams), a dedicated serial configuration interface (compatible with Altera FLEX/ACEX configuration schemes), low-power CMOS process technology, and an operating voltage range that aligns with classic 5V/3.3V Altera FPGA families. The 32-pin TQFP (7x7) package provides a compact footprint with surface-mount compatibility for volume manufacturing. Typical applications include Altera FLEX 10K, FLEX 6000, ACEX 1K, APEX 20K, and early Cyclone FPGA configuration storage in telecom, industrial control, networking, and embedded systems designs. The EPC144TC32 is most commonly found in legacy Altera-based designs and is often specified in long-lifecycle industrial and aerospace programs. When designing, note that the EPC144TC32 is OTP (one-time programmable) — once programmed, the bitstream cannot be erased or rewritten. For designs that require field re-programmability, the EPC2 or EPC4 erasable PROMs in the same TQFP-32 footprint should be considered. Verify that the specific Altera FPGA configuration mode (PS, AS, or JTAG) supports this device, as the EPC144 family targets older serial configuration schemes.

EPC144TC32N

EPC144TC32N - Enhanced Configuration Device, 32-pin TQFP | Intel (Altera)

The Intel (formerly Altera) EPC144TC32N is an Enhanced Configuration (EPC) device in a 32-pin TQFP package, used to configure SRAM-based LUT devices such as the FLEX 8000 and FLEX 10K FPGA families. The EPC1441 device stores 440,800 bits of configuration data in serial EEPROM and supports in-system programmability via IEEE Std 1149.1 (JTAG) boundary-scan test, enabling designers to program, verify, and re-program FPGAs on the board without removing the device. An EPC (Enhanced Configuration) device is a serial-configuration memory that boots an SRAM-based FPGA at power-up. It sits on a dedicated serial configuration chain (typically 4- or 5-wire: nSTATUS, CONF_DONE, nCONFIG, DCLK, DATA0) and serially shifts the bitstream into the FPGA on every reset. EPC devices belong to the broader hierarchy of non-volatile configuration memory, distinct from parallel flash, microcontrollers, or CPLDs - they are specialized one-function parts optimized for low-cost, small-to-medium FPGA bitstream storage. The EPC1, EPC2, EPC4, EPC8, EPC16, EPC64 and EPC1441 form a density ladder from 1 Mbit to 16 Mbit. Key features of the EPC144TC32N include 440,800-bit (approximately 440 Kbit / ~54 KB) storage, 3.3 V core supply, in-system programmability through JTAG (IEEE 1149.1), a 4-pin JTAG interface (TMS, TCK, TDI, TDO), and industrial operating temperature range. The TQFP-32 surface-mount package gives a low profile and supports standard reflow soldering. Unlike parallel flash memory, the EPC1441 outputs configuration data serially at the DCLK rate controlled by the FPGA, simplifying board layout. Architecturally, the EPC144TC32N uses a serial EEPROM array with on-chip charge-pump for byte-write operations, an oscillator for internal timing, and a JTAG TAP controller for boundary-scan programming. The serial protocol is Altera-proprietary and designed so that the FPGA acts as the master during configuration - the EPC144TC32N does not arbitrate the bus. Programming voltage VPP is generated internally from VCC in normal mode, eliminating the need for an external 12 V supply. Typical applications include configuring Altera (now Intel) FLEX 8000, FLEX 10K, ACEX 1K, APEX 20K, Mercury, and older APEX II FPGAs in production hardware, prototype boards, and industrial control systems. The EPC1441 is commonly paired with mid-density FPGAs requiring bitstreams between 50 KB and 130 KB. For higher-density FPGAs (Stratix, Cyclone, Arria, Agilex) Intel now recommends their second-generation EPCQ serial flash, which uses standard SPI and supports higher clock rates. When designing with this device, ensure that the JTAG chain shares TDI/TDO with the FPGA in the proper order so the configuration device is accessible to the Quartus programmer. Decoupling (100 nF + 10 uF close to VCC and VPP pins) is required to keep the charge-pump stable during ISP. The EPC1441 supports both 3.3 V and 5 V tolerant I/O on the FPGA-facing pins, but VCC must remain within 3.0 V-3.6 V.

EPC144TI32

EPC144TI32 - 32-Pin TQFP Altera Configuration Device | Intel FPGA

The Altera (Intel) EPC144TI32 is a serial configuration PROM from the EPC144 family, providing 441,000 bits of one-time-programmable serial configuration storage in a 32-pin TQFP package. Designed for use with Altera/Intel FPGAs such as the Cyclone, Stratix, and APEX families, this device loads configuration bitstreams into the FPGA's SRAM-based LUTs at power-up via the dedicated configuration interface. The 'I' suffix indicates the industrial temperature grade, and the 'N' indicator confirms lead-free / Pb-free construction per industry standards. A configuration PROM is a non-volatile memory device purpose-built for storing FPGA configuration bitstreams. In the Altera configuration hierarchy, the EPC family sits below SRAM-based LUTs (which must be re-loaded at every power-up) and above the host processor or JTAG chain. The PROM bitstream is shifted into the target FPGA's configuration RAM through a serial daisy-chain, with the FPGA's nCONFIG, nSTATUS, CONF_DONE, and DCLK signals orchestrating the handshake. Key features of the EPC144TI32 include 441,000 configuration-bit density (sufficient for mid-density FPGAs), a TQFP-32 surface-mount footprint, single-supply operation (typically 3.3 V VCC), in-system programmability through the JTAG-compatible interface, and industrial operating temperature range. It is pin-to-pin compatible with other EPC144 TQFP-32 variants, allowing design reuse across the EPC144 family and between industrial- and commercial-grade versions of the same density. Designers also benefit from drop-in compatibility with higher-density EPC devices (EPC1, EPC2, EPC4) in many reference designs, easing migration as design complexity grows. From an architectural standpoint, the EPC144TI32 uses a memory cell optimized for fast serial output rather than random-access read performance. Programming is performed in-system through the IEEE 1149.1 JTAG chain shared with the target FPGA. Device endurance is rated for one-time-programmable (OTP) operation; for in-application reconfigurability Altera recommends the EPCS-series (Serial Configuration) devices instead. Typical applications include FPGA configuration memory for industrial controllers, factory automation, telecommunications line cards, and test-and-measurement instruments that require reliable, compact, one-time-programmed FPGA boot storage. The TQFP-32 industrial-grade part also supports -40C to +85C ambient operation, suiting outdoor and uncontrolled-environment deployments. When designing with this device, ensure that the JTAG chain routing keeps the PROM-to-FPGA DCLK trace short and well-terminated to avoid configuration errors. VCC decoupling requires a 0.1 uF ceramic capacitor placed within 5 mm of the VCC pin. For designs that may require future bitstream updates, consider the EPCS-series instead. This page synthesizes distributor pricing, drop-in alternatives, application guidance, and practical design notes not found in the original EPC144 datasheet, giving engineers a single source for evaluating the EPC144TI32 against modern configuration PROM options.

EPC1604PC8

EPC1604PC8 - 5V/3.3V 64K-bit Serial Config EPROM DIP-8 | Altera

The Altera EPC1604PC8 is a 64 Kbit (64K x 1) serial CMOS configuration EPROM designed to store configuration bitstreams for Altera FLEX-class SRAM-based FPGAs. Housed in an 8-pin PDIP through-hole package, it operates from a single 5.0 V or 3.3 V supply, provides a simple 4-pin serial interface (nCS, DCLK, DATA, OE), and enters near-zero standby current once configuration completes. Maximum supply voltage is 5.25 V and maximum access time is 75 ns. A serial configuration EPROM is a one-time- or few-time-programmable non-volatile memory used exclusively as a boot/boot-loader store for volatile FPGAs. Within the broader component taxonomy, the EPC1604PC8 sits in the hierarchy EPROM -> non-volatile memory (NVM) -> memory IC -> integrated circuit. Each time the host system powers up, the FPGA reads its bitstream serially out of the EPROM over the 4-pin Altera FLEX configuration interface; the EPROM itself is not user-addressable RAM and is not suitable for general-purpose data storage. Key features include 64 Kbit density organized as 64K x 1 bit, 75 ns maximum access time, CMOS process for low active current, near-zero standby current after configuration, in-system programmability via Altera's programming tools, and a commercial 0 C to +70 C operating temperature range. The simple 4-pin interface eliminates the need for an external configuration controller, allowing the EPROM to connect directly to the FLEX configuration pins. Architecturally, the EPC1604PC8 integrates a serial address counter, an on-chip clock generator synchronized to the DCLK input from the FPGA, an OTP/UV-erasable EPROM cell array, and a serial data output driver gated by the OE (output enable) pin. The device is designed to daisy-chain with other EPC-family EPROMs to support larger FLEX devices that require more than 64 Kbits of configuration data. Typical applications include legacy FLEX 8000 / FLEX 10K configuration storage, industrial control retrofits, replacement of obsolete boot PROMs on legacy FPGA boards, and educational/development platforms that demonstrate FPGA configuration flow. Designers also use the EPC1604 in low-volume production where a discrete boot PROM is preferred over a flash-based controller. When designing with this part, note that the EPC1604PC8 is a legacy product in an 8-pin PDIP package - verify that the target FLEX FPGA supports a 5 V tolerant serial configuration interface or that a modern Enhanced Configuration Device (EPCQ, EPCS) is not required. Daisy-chain pin assignments must follow the Altera application note for multi-device configuration chains.

EPC160C100

EPC160C100 - Altera Enhanced Configuration Device | Intel FPGA

The Altera EPC160C100 is an Enhanced Configuration Device (EPC) designed to configure SRAM-based look-up table (LUT) FPGAs in the Altera/Intel family, providing non-volatile storage for FPGA configuration bitstreams in a 100-pin package form factor. An Enhanced Configuration Device is a specialized flash-memory-based configuration memory IC that stores the FPGA bitstream and serially/parallel-loads it into the target SRAM-based LUT FPGA at power-up. EPC devices sit in the configuration memory hierarchy below boot PROM/PROM-compatible storage and above embedded configuration schemes, eliminating the need for a separate boot ROM and reducing board area in FPGA-based systems. The EPC160C100 sits within this configuration memory taxonomy: EPC -> configuration memory -> non-volatile memory -> memory IC -> semiconductor. Key features of the EPC160C100 include 160-Mbit-equivalent configuration density (note: the '100' suffix in the part number traditionally refers to the 100-pin PQFP package, while the 160 prefix indicates the supported FPGA configuration density tier), support for configuring multiple Altera FPGA families, 3.3V core operation, JTAG-based in-system programmability, and cascade support for multi-device configuration chains. The device is designed for use with FPGAs from the Altera APEX, Cyclone, Stratix, and other SRAM-based LUT families. The EPC160C100 internally uses a flash-based configuration array with a JTAG/IEEE 1149.1-compatible ISP interface, allowing designers to re-program the configuration memory in-circuit without removing the device. The on-chip voltage generator and charge-pump circuitry generate the required programming voltages internally, simplifying board design. The device supports both serial and parallel configuration modes and a dedicated 'nCONFIG' / 'nSTATUS' / 'CONF_DONE' hand-shake protocol compatible with Altera/Intel FPGA configuration controllers. Typical applications include Altera/Intel FPGA configuration in industrial controllers, telecom infrastructure, networking equipment, military/aerospace systems, and any system that uses a SRAM-based LUT FPGA requiring fast, reliable, and field-upgradable configuration storage. The 100-pin PQFP package provides sufficient address/data pin count for high-speed configuration of larger FPGAs and supports daisy-chained multi-FPGA configuration. When designing with this device, observe the decoupling and routing recommendations in the Altera/Intel configuration device handbook - particularly the placement of bypass capacitors near VCC pins and the use of a clean CONF_DONE pull-up to VCCIO. Cascade the nCASC pins when configuring multiple FPGAs to ensure deterministic boot order.

EPC160I100

EPC160I100 - Altera Enhanced Configuration Device, QFP-100 | Intel FPGA

The Altera EPC160I100 is a 3.3V Enhanced Configuration (EPC) device designed to configure SRAM-based Altera LUT devices including APEX II, APEX 20K, Mercury, ACEX 1K, FLEX 10K, and FLEX 10KE families. It integrates a flash memory array with a controller to deliver fast, in-system configuration and reconfiguration of SRAM-based FPGAs over JTAG or passive serial interfaces. Per the Altera Enhanced Configuration Devices datasheet, the device supports 5.0V tolerant I/O for mixed-voltage systems and provides ISP via JTAG (IEEE Std 1149.1) plus dual-purpose data/address multiplexing for flexible design-in. An Enhanced Configuration Device is a non-volatile configuration memory plus controller integrated circuit used to store FPGA bitstreams and load them at power-up. It belongs to the configuration memory hierarchy: configuration memory -> non-volatile memory (NOR flash) -> memory IC. Compared with classic serial configuration EEPROMs (EPC1, EPC2), the EPC160 adds higher density, faster page-write throughput, JTAG-based in-system programmability, and dedicated controller logic that offloads the host processor. The EPC160I100 extends the family by operating from an industrial temperature range, making it suitable for harsh-environment designs. Key differentiating features include 1.6 Mb of configuration storage, parallel/byte-wide data interface, 5.0V tolerant inputs while operating at 3.3V core, JTAG (IEEE 1149.1) ISP, and an industrial temperature rating of -40C to +85C. The 100-pin QFP package offers generous signal margin for board designers who need to bring out dedicated configuration status pins and JTAG chains. Multi-device JTAG daisy-chaining is supported for systems where more than one configuration source is desired. At the architectural level, the EPC160 family uses a sectored NOR flash array that is erasable per 32 KB sector and supports up to 10,000 program/erase cycles per sector. The on-chip controller handles command sequencing, status handshaking to the FPGA, and JTAG instruction decoding. Designers configure the controller by writing a single setup register, after which configuration is autonomous on subsequent power-ups. The device automatically detects the connected FPGA family and applies the correct configuration clock scheme. Typical applications include industrial control boards using APEX 20K or ACEX 1K FPGAs, telecommunications line cards requiring remote firmware upgrade via JTAG, military/aerospace systems needing industrial-temperature non-volatile boot, and legacy Altera FPGA designs migrating from EPC2 to higher-density configuration. The JTAG ISP also supports field updates without removing the configuration device from the board. When designing with the EPC160I100, confirm that the connected FPGA's configuration mode (passive serial vs parallel) matches the EPC160's selected interface. Place a 0.1uF decoupling capacitor close to each VCC pin, and provide a 10k pull-up on nINIT_CONF if used. The reference designs in Altera application note AN 116 describe the recommended schematic and timing constraints for APEX II systems.

EPC164C88N

EPC164C88N - Altera/Intel Configuration Device for SRAM FPGAs

The Intel EPC164C88N is a member of the Altera Enhanced Configuration Device (EPC) family, a 16-Mbit in-system programmable configuration memory designed to load the SRAM-based look-up tables of the Cyclone, Cyclone II, Cyclone III, Stratix, Stratix II, Stratix III, Stratix GX, Stratix II GX, and HardCopy II device families. Housed in an 88-pin Ultra FineLine BGA (UBGA) measuring 11x8 mm, the part provides non-volatile configuration storage with a dedicated FPGA configuration interface, eliminating the need for external boot PROMs or microcontroller-based configuration schemes in production hardware. According to the EPC family datasheet, this device family supports 1.8V, 2.5V, 3.3V, and 5.0V FPGA core and I/O voltages, allowing it to interface directly with Altera SRAM FPGAs without level shifters. A configuration PROM is a non-volatile memory specifically optimized to deliver the FPGA configuration bitstream to the SRAM-based configuration cells of an FPGA at power-up. These devices sit in the broader hierarchy of memory ICs (non-volatile memory -> PROM/EPROM/Flash -> configuration memory) and are designed for one-time or in-system reprogrammable FPGA configuration rather than general-purpose data storage. Unlike a generic SPI flash, an EPC device implements the Altera-specific configuration controller (passive serial, fast passive parallel, or FPP modes) so that no external host processor is required to load the FPGA. This category is sometimes referred to as an FPGA boot PROM, configuration PROM, or configuration bitstream memory. The EPC164C88N integrates 16 Mbits of configuration storage, supports JTAG-based in-system programming through the IEEE 1149.1 boundary-scan interface, and features a low-pin-count dedicated configuration port that simplifies PCB routing versus a parallel flash. The UBGA-88 footprint is a thermally enhanced substrate that supports industrial operating temperatures, making the device suitable for production volumes where factory programming is preferred. Designers can reconfigure the device on the bench without removing it from the board, which shortens development cycles for FPGA prototype spins. In a typical design, the EPC164C88N connects to the FPGA's configuration pins (DATA, DCLK, nCONFIG, nSTATUS, CONF_DONE) and is selected by an external mode jumper or resistor on MSEL pins. At power-up, the FPGA drives nSTATUS low, the EPC clocks out the bitstream on DATA synchronized to DCLK, and the FPGA asserts CONF_DONE once loading is complete. The entire transaction is transparent to the application processor and is governed by Altera's configuration protocol rather than by user software, which simplifies BOM and reduces firmware complexity. Common applications include factory-loaded configuration for Cyclone III development boards, industrial controllers built around Stratix III logic, and long-life-cycle industrial products where supply-chain traceability requires a single-source configuration IC from Intel. When designing with this part, ensure that the MSEL[2..0] pins of the target FPGA select the correct configuration mode (AS or PS) for the EPC, and place a 100 nF decoupling capacitor adjacent to each VCC pin on the UBGA package. Designers should also confirm the supported FPGA voltage mode (3.3V or 1.8V) before mixing EPC164C88N with newer low-voltage FPGA families.

Conceptually it sits between generic serial PROMs (small bitstream storage) and full embedded memory controllers (large, multi-device solutions). EPC devices are purpose-built companions to Altera FPGAs, exposing a serial configuration interface that the FPGA masters at power-up. The EPC16 variant adds density, higher programming throughput, and cascade support relative to EPC4 and EPC8 predecessors. Key features include 16,777,216 bits (16 Mb) of configuration storage, cascadable architecture that allows two EPC devices to be chained for larger FPGA bitstreams, and a low-pin-count serial interface that frees board space. The device operates over the industrial temperature range and supports in-system programming, allowing firmware upgrades without removing the FPGA from the board. Technically, the EPC1664PI8 uses a 3.3 V supply and exposes a four-signal serial configuration bus (DATA, DCLK, nCONFIG, CONF_DONE plus JTAG). Programming algorithms are defined by the Altera Quartus II toolchain; the device appears as a JTAG-accessible target for boundary-scan and ISP. Read-back and verify operations are supported, simplifying board-level bring-up. Typical applications include factory programming stations for Altera/Intel Stratix and Cyclone boards, production programming of FPGA-based industrial controllers, telecom line cards, and legacy FPGA-based designs where board rework is undesirable. The PDIP-8 form factor also supports through-hole prototype sockets and easy rework in engineering builds. When designing in this part, ensure that the FPGA's MSEL pins select the EPC configuration mode, that nCONFIG and CONF_DONE are pulled correctly, and that the JTAG chain order matches the Quartus generated SOF/JIC file. Designers moving from 3.3 V to 1.8 V FPGAs should re-validate the level-shifter on the serial data path.

Key features include 16 Mb of flash storage, in-system programmability via JTAG, support for Fast Passive Parallel (FPP), Passive Serial (PS), Passive Parallel Asynchronous (PPA), and Passive Parallel Synchronous (PPS) configuration schemes, plus a 3.3V core / 1.8V-3.3V I/O interface. The device also supports compression for Stratix/Stratix II, multi-device configuration via daisy-chaining, and remote update through dedicated configuration schemes. The EPC16C100T uses a dedicated configuration controller that handles handshaking with the host FPGA. Its 100-pin PQFP package offers a through-hole-friendly footprint with standard 0.65 mm lead pitch, and the JTAG chain allows board-level in-system programming using the IEEE 1149.1 boundary-scan infrastructure without removing the device from the board. Typical applications include Stratix-series FPGA configuration in telecommunications line cards, industrial control boards, and military/aerospace embedded systems where field-upgradeable firmware and reliable single-chip boot are essential. The remote-update feature enables fail-safe firmware revision management in remote, unattended installations. When designing with this device, ensure that nCONFIG, nSTATUS, and CONF_DONE follow Altera reference design guidelines. The JTAG chain must be correctly ordered to avoid back-drive contention, and the decoupling network (typically 0.1 uF + 10 uF bulk) must be placed close to VCC pins.

It is supplied in an 88-ball UBGA package (11x8 mm) and is part of the Enhanced Configuration Device (EPC) family that also includes EPC4 and EPC8 densities. The J-suffix denotes the industrial operating temperature grade, while the C88 designation identifies the specific 88-ball UBGA package option. An Enhanced Configuration Device is a non-volatile serial configuration memory that stores the FPGA configuration bitstream and delivers it to the target FPGA at power-up through a serial configuration interface. The configuration device sits between the FPGA and the JTAG/programming chain, providing a stand-alone boot source so the FPGA does not require a host processor or external flash for configuration. Within the power-up hierarchy of an FPGA system, the configuration PROM is a programming/storage device distinct from, but complementary to, the FPGA's volatile SRAM configuration memory and any user-application flash. Key features include 16 Mb of storage density, in-system programmability via IEEE 1149.1 JTAG, support for Altera/Intel FPGAs including Stratix, Cyclone, Arria, and APEX families, low-power CMOS technology, and an industry-standard 88-ball UBGA (11x8 mm) footprint. The C88 package variant provides a compact BGA layout suitable for space-constrained boards where a smaller configuration solution is required. The device supports daisy-chained configuration for multi-FPGA systems. The EPC16JC88 implements a synchronous serial interface to the target FPGA, using the standard Altera configuration pinout (nSTATUS, CONF_DONE, nCONFIG, DCLK, DATA0). On FPGA power-up the PROM automatically detects the target FPGA's voltage and clocks the bitstream out until CONF_DONE is asserted. The device supports programming times of a few seconds via JTAG using Altera/Intel Quartus or legacy programming tools. Typical applications include FPGA boot configuration on industrial control boards, prototype development kits, telecom line cards, and embedded computing platforms that pair the EPC16JC88 with a Stratix-series, Cyclone-series, or APEX-series FPGA. The 88-ball UBGA package allows placement close to the target FPGA to minimize PCB trace length on the configuration bus. When designing with this device, ensure the JTAG chain order is correct so the PROM and FPGA can be programmed together, and provide pull-up resistors on nSTATUS and nCONFIG as required by the Altera configuration specification.

The Altera EPC16Q100 is a 16-megabit in-system programmable Configuration PROM designed to store configuration data for high-density Altera FPGAs such as the Stratix, Cyclone, and APEX families. It uses a 100-pin PQFP (Plastic Quad Flat Pack) package, offers a 3.3V core supply, and provides a single-device, high-speed configuration solution for very high-density FPGA designs. An FPGA configuration PROM is a non-volatile memory device that holds the bitstream loaded into an SRAM-based FPGA at power-up. Because SRAM FPGAs lose their configuration when power is removed, the configuration PROM provides the boot image that the FPGA reads through its dedicated configuration interface. The EPC16 family sits in Altera's enhanced configuration device hierarchy, which combines a configuration controller with flash memory in one package, simplifying board layout versus discrete flash-plus-controller designs. Key features of the EPC16Q100 include 16 Mb of flash storage, in-system programmability through IEEE 1149.1 (JTAG), support for multiple I/O voltages (3.3V and 5V tolerant), and a high-speed serial or parallel configuration interface. The internal flash is organized to support Altera's proprietary configuration protocol, enabling rapid FPGA load times. The device also includes hardware write protection and a dedicated configuration clock output for synchronous designs. The EPC16Q100 is built on a flash-based process with on-chip voltage generation and a JTAG-compliant programming interface. Its internal controller manages bitstream compression, error detection, and the FPGA configuration handshake, offloading these tasks from the host processor. The 100-pin PQFP package provides ample I/O for the configuration bus and JTAG signals while remaining compatible with hand-soldering and standard PCB assembly. Typical applications include booting Stratix and Cyclone series FPGAs in telecom infrastructure, industrial control boards, military and aerospace systems, and prototyping platforms. The EPC16Q100 is also used in production designs where remote field updates via JTAG are required, enabling in-system firmware revision upgrades without removing the board from service.

It supports multi-bit configuration data compression, an 8/16-bit data width, and serial configuration via the Altera enhanced controller block, delivering fast, single-device configuration for very-high-density FPGAs such as Stratix, APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K families. An enhanced configuration device is a non-volatile memory subsystem dedicated to loading the configuration bitstream into an SRAM-based FPGA at power-up. Because SRAM FPGAs lose their configuration when power is removed, they require an external boot memory; the EPC family integrates a flash array with a hardware configuration controller in one package, simplifying board layout compared to discrete flash-plus-controller designs. Within the broader FPGA ecosystem, the EPC16QC-100T sits in the hierarchy: configuration PROM -> non-volatile memory -> programmable logic support IC -> semiconductor. Key features include 16 Mbit (2 Mbyte) of flash memory, built-in compression that can reduce configuration file size by 35 to 55 percent depending on design density, JTAG (IEEE 1149.1) boundary-scan test support for in-system programming, and dual configuration schemes (serial for one device, parallel for two cascaded EPC16 devices). The device operates from a 3.3 V supply and supports cascading to address larger FPGA bitstreams via Chip Enable (nCE) and Output Enable (nOE) handshake signals. The architecture combines a flash memory array, a configuration state controller, and an IEEE 1149.1 JTAG interface on a single die. The controller handles the configuration algorithm, error detection, and chip-select sequencing, while the flash array stores the compressed FPGA image. Compression is performed in Altera's Quartus design software, and the device transparently decompresses the bitstream on FPGA load. Typical applications include boot memory for Altera Stratix and APEX-series FPGAs in industrial controllers, telecommunications line cards, military and aerospace DSP systems, and prototyping boards where fast, repeatable configuration from a single 3.3 V flash source is required. The 20 x 14 mm PQFP-100 footprint is compatible with earlier EPC4 and EPC8 enhanced configuration devices, simplifying migration. When designing with this part, confirm that the Quartus programmer software version supports the EPC16 device family and that the target board implements the proper nCE/nOE handshake for multi-device chains. The PQFP-100 package is surface-mount but uses a 0.65 mm pitch leadframe, so PCB assembly requires careful solder-paste stencil and reflow profiling. This page synthesizes distributor availability, parametric context, and engineering guidance beyond the bare datasheet, helping engineers select configuration memory and pin-compatible variants for both new designs and legacy Altera FPGA platforms.

EPC16QC100 - 16Mb FPGA Configuration PROM, 100-PQFP | Altera

The Altera EPC16QC100 is a 16-Mbit in-system programmable Flash configuration PROM designed to store and deliver configuration bitstreams to high-density Altera FPGAs. Housed in a 100-pin PQFP (20x14 mm) package, it operates with a 33 MHz configuration clock and supports a wide 3.0V to 3.6V supply range, providing a single-device, high-speed configuration solution that eliminates external boot memory. A configuration PROM (sometimes called a configuration memory or boot PROM) is a non-volatile serial memory dedicated to storing an FPGA's bitstream. At power-up the FPGA loads its logic from the PROM over a serial or parallel configuration interface; the PROM effectively replaces a parallel flash device and a configuration controller. Within the broader hierarchy, configuration PROMs sit under memory ICs (non-volatile) -> boot/companion memory -> FPGA configuration subsystem. Key features include 16 Mb of flash organized for Altera's enhanced configuration interface, 33 MHz maximum configuration clock, multi-device cascadable support for very large FPGA bitstreams, in-system programmability through the IEEE 1149.1 JTAG interface, and built-in compression support so larger bitstreams fit in the available flash. Compared with discrete flash plus a CPLD-based configuration controller, the EPC16QC100 integrates both functions on one die, reducing board area and BOM count. Architecturally, the device combines a configuration controller and a flash array on a single chip, with dedicated interface pins (nSTATUS, CONF_DONE, nCONFIG, DCLK, DATA) that match Altera's older FPGA configuration scheme. It supports Stratix, APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K device families. Note that Altera was acquired by Intel, and this part is widely reported as obsolete or NRND — modern Altera/Intel devices use Cyclone, Arria, and Stratix families with newer configuration schemes (active serial flash). Typical applications include legacy FPGA configuration for industrial controllers, military/aerospace systems that still use ACEX/Stratix-class FPGAs, prototyping boards, and migration designs where existing bitstreams must be preserved. Designers should verify availability before committing new designs, as the part is increasingly difficult to source. Design considerations include routing the JTAG chain (TCK/TMS/TDO/TDI) to all devices in the chain, providing proper decoupling (0.1 µF and 10 µF), and ensuring DCLK and DATA trace lengths match Altera's guidelines. Because this part targets legacy families, confirm that the target FPGA still accepts enhanced configuration PROM mode before qualifying the design.

EPC16QC100-TAAC80

EPC16QC100-TAAC80 - 16Mb FPGA Config PROM, 100-PQFP | Altera

The Altera EPC16QC100-TAAC80 is a 16-Mbit enhanced configuration device designed as a single-chip, in-system programmable solution for very high-density SRAM-based FPGAs. Housed in a 100-pin PQFP (Plastic Quad Flat Pack) package measuring 20x14 mm, this Altera/Intel configuration PROM delivers configuration bitstreams to companion FPGAs such as Stratix, APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K device families via a dedicated configuration controller and embedded flash memory array. Key headline parameters include a 16-Mbit flash storage density, multi-mode configuration (FPP, PS, AS, JTAG), compression support that reduces configuration file size by 30-55%, and supply voltage of 3.3 V (core) with 5 V tolerant I/O. An FPGA configuration PROM is a non-volatile serial/parallel memory device whose role is to load the SRAM-based LUT fabric of an FPGA at power-up. Because SRAM FPGAs lose their configuration on power-down, the host board requires an external boot memory - the configuration PROM - to store the bitstream. The enhanced configuration family (EPC4, EPC8, EPC16) integrates both the configuration controller and the flash array on a single die, eliminating the need for an external controller and reducing board complexity versus older EPROM-based EPC1/EPC2 devices. Key differentiating features of the EPC16QC100 include built-in data compression (which reduces configuration time and storage requirements), JTAG 1149.1 boundary-scan support for in-system programming, multi-voltage I/O (1.8 V, 2.5 V, 3.3 V, 5 V) for compatibility with all supported FPGA families, and a dedicated nSTATUS/nCONFIG handshaking interface. The 'QC100' suffix indicates the 100-pin PQFP package; the '-TAAC80' suffix designates tape-and-reel packaging with a specific date/lot code per Altera ordering nomenclature. The EPC16QC100 internally separates the configuration controller logic from the flash memory block, with the controller handling the bitstream handshake (DCLK, DATA, nCS, OE), decompression, and error checking. Configuration modes supported include Passive Serial (PS), Fast Passive Parallel (FPP), JTAG, and Active Serial (AS) when cascaded with a serial configuration device, enabling flexible design-in across Altera FPGA families. Typical applications include Stratix and APEX 20K FPGA boot storage, industrial control systems requiring reliable SRAM FPGA configuration, networking line cards with high-density FPGAs, military and aerospace FPGA-based processing boards, and any design that needs a robust, in-system programmable configuration memory for legacy Altera SRAM FPGAs. The compression feature is particularly valuable in cost-sensitive designs that need to minimize configuration storage. When designing with the EPC16QC100-TAAC80, verify that the target FPGA's configuration mode matches the PROM's supported modes. For JTAG programming, connect TCK, TMS, TDI, and TDO through the device's JTAG chain; the EPC16 will appear as a single JTAG device with its own BYPASS instruction. The nINIT_CONF and OE pins must be tied correctly to the target FPGA's nCONFIG/nSTATUS pins to enable clean handshake during multi-device configuration cascades.

EPC16QC100DM

EPC16QC100DM - 16Mb FPGA Config PROM, 100-Pin QFPA | Intel

The Intel EPC16QC100DM is a 16-Mbit serial configuration memory device designed to store configuration bitstreams for Intel (formerly Altera) FPGA families including Stratix, Cyclone, and APEX series in 100-pin QFPA packaging. The device supports multi-voltage I/O (3.3V/2.5V) operation and uses a serial peripheral interface (SPI) to deliver configuration data to the host FPGA at speeds up to 40 MHz. Housed in a 100-pin Plastic Quad Flat Pack (PQFP-100), the EPC16QC100DM targets industrial temperature ranges and provides high-density, single-chip configuration storage for mid-to-large FPGA designs. A Configuration PROM (or FPGA configuration memory) is a non-volatile serial memory specifically designed to load configuration bitstreams into SRAM-based FPGAs at power-up. Unlike general-purpose EEPROMs, configuration PROMs implement the FPGA-specific serial configuration protocol, supporting multi-device cascading and in-system programming. EPC16 belongs to the configuration memory category, which sits within the FPGA support ecosystem hierarchy: FPGA support IC -> Memory IC -> Configuration PROM -> Non-volatile memory -> Semiconductor IC. Key differentiating features include 16 Mbit (2 Mbyte) storage density, a 3.3V core supply with 2.5V/3.3V selectable output voltage for compatibility with older and newer FPGA families, and an industry-standard SPI serial interface. The device supports in-system programmability through the IEEE 1532/JTAG boundary-scan chain, and the parallel/serial configuration modes are selectable via hardware pins. Internal 3.3V regulation from a 5V VCC simplifies board design when the host FPGA requires 3.3V I/O. Architecturally, the EPC16QC100DM integrates a 16-Mbit NOR-flash array with an FPGA-compatible serial configuration controller and a JTAG-compliant programming interface. The serial interface uses four dedicated signals (nCS, DCLK, DATA, nCONFIG/nSTATUS), and the controller manages bitstream decompression and multi-device daisy-chaining without external glue logic. Error detection is handled by a built-in CRC verifier that signals FPGA nSTATUS if any bitstream corruption is detected at load time. Typical applications include configuring Stratix II/III FPGAs in telecommunications line cards, mid-range Cyclone III/IV designs in industrial controllers, APEX 20K and ACEX 1K systems in legacy test-and-measurement equipment, and Avionics/MIL-STD-1553 interface cards where 100-pin PQFP packages remain standard. The 16 Mbit density is well matched to mid-density FPGAs (roughly 30k-120k logic elements), and the 3.3V/2.5V VIO option lets one PROM support multiple FPGA generations on the same PCB. When designing with the EPC16QC100DM, ensure that nCS, DCLK, and DATA traces are length-matched to within 1 cm and routed with 50 ohm controlled impedance to avoid bitstream corruption at the maximum 40 MHz DCLK rate. For multi-device configuration chains, daisy-chain nCASC between PROMs and respect tCF parameter (typically 100 ms) before issuing nCONFIG.

EPC16QC100II

EPC16QC100II - 16Mb FPGA Configuration PROM, 100-PQFP | Altera (Intel)

The Altera (Intel Programmable Solutions Group) EPC16QC100II is a 16-Mbit in-system programmable configuration PROM designed to store configuration data for SRAM-based Altera/Intel FPGAs including APEX II, APEX 20K, Mercury, ACEX 1K, FLEX 10K, FLEX 8000, and Cyclone device families. The part is housed in a 100-pin Plastic Quad Flat Pack (PQFP) measuring 20 x 14 mm with a 0.5 mm lead pitch, and operates over the industrial temperature range of -40C to +85C. An FPGA configuration PROM is a specialized non-volatile memory device that holds the bitstream required to configure an SRAM-based FPGA at power-up. Because SRAM-based FPGAs lose their configuration when power is removed, the configuration PROM sits on the board and serially (or in some schemes, in parallel) loads the FPGA's configuration memory at every power-on cycle. EPC configuration PROMs sit at the bottom of the configuration-device hierarchy: configuration PROM -> serial configuration memory -> non-volatile boot memory -> FPGA configuration subsystem -> programmable logic device. Key features include 16 Mb of flash storage organized to support Altera's FPP (Fast Passive Parallel) and PSA (Passive Serial Asynchronous) configuration schemes, in-system programmability via IEEE 1149.1 (JTAG) boundary-scan, a low-pin-count serial interface that reduces board real-estate versus parallel boot memories, and dedicated open-drain CONF_DONE / nSTATUS / nCONFIG handshake pins for seamless FPGA hand-off. The "II" suffix denotes the industrial-grade temperature variant. The EPC16QC100II uses a 3.3 V core supply with 5 V tolerant I/O on configuration pins, supporting cascading of multiple PROMs to address FPGAs whose bitstream exceeds 16 Mb. Internally, the device implements a state machine that handles JTAG ISP (In-System Programming) and orchestrates the serial clock and data handshake required by the target FPGA. Compared to early EPC1/EPC2 PROMs, the EPC16 adds compression support, reducing the on-board PROM silicon needed to load a given FPGA by approximately 30%. Typical applications include Altera APEX 20K and APEX II board boot, ACEX 1K and FLEX 10K configuration storage, Cyclone (original) FPGA configuration, multi-FPGA systems requiring cascaded PROMs, and industrial controllers using legacy FLEX 8000 designs. The part is also a common reference design point in educational FPGA labs. Designers should note that the EPC16QC100II has been superseded by newer Altera/Intel configuration devices such as the EPCQ and EPCQ-A families for current FPGA families; for new designs targeting Cyclone IV / Cyclone 10 / Arria / Stratix, engineers should select EPCQ16 or EPCQ-A16 instead. However, the EPC16 remains the supported configuration device for many legacy designs and continues to ship from authorized distributors.

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.

It provides non-volatile storage of FPGA configuration bitstreams and supports high-speed serial or parallel configuration via Altera's passive-serial, passive-parallel-synchronous, and passive-parallel-asynchronous modes. The "SS" suffix designates the 3.3V VCC device variant in the EPC16 family, optimized for low-power operation. A configuration PROM is a specialized serial-interface memory IC that retains the FPGA's bitstream when the system is powered down and re-loads it into the FPGA's SRAM configuration cells on power-up. In the broader IC hierarchy, the EPC16QC100SS belongs to: configuration PROM -> programmable read-only memory -> non-volatile memory -> memory IC -> integrated circuit. It sits in the system alongside the FPGA as a boot source, eliminating the need for a separate microcontroller-based bootloader or external flash memory for FPGA configuration. Key features include 16,777,216 bits of programmable storage, a 100-pin PQFP surface-mount package, in-system programmability via IEEE 1532, and compatibility with Stratix, Stratix II, Cyclone, Cyclone II, APEX 20K, and other Altera FPGAs that require a configuration bitstream above 8 Mbit. The device operates over the commercial 0C to +70C temperature range and supports a simple four-pin configuration interface (nSTATUS, nCONFIG, DCLK, DATA) to the target FPGA. Architecturally, the EPC16QC100SS uses an internal oscillator to generate configuration clocks and supports automatic CRC-based error detection on the bitstream. Its multi-voltage I/O (VCCSEL pin) is selectable between 3.3V and 2.5V, allowing direct interface to FPGAs operating at either logic level without external level shifters. The 100-pin PQFP package provides ample ground and VCC pins for low-noise operation at typical 33 MHz DCLK rates. Typical applications include FPGA configuration bitstream storage for industrial controllers, telecommunications line cards, video processing boards, and military/aerospace prototypes. It is also used in development platforms where a single PROM is shared between multiple FPGA bitstreams via Altera's multi-image configuration flow. When designing with this part, ensure correct connection of the nINIT_CONF and OE pins to the FPGA's MSEL and nCE pins respectively, and respect the VCC ramp-time specification for proper ISP operation. Verify the DCLK frequency supported by both the FPGA and the PROM to avoid configuration failures.

A configuration PROM is a non-volatile memory device that holds the FPGA bitstream and serially transfers it to the FPGA during the configuration phase, before the FPGA begins user-mode operation. EPC (Enhanced Configuration) devices sit in the broader hierarchy of programmable read-only memories -> non-volatile memory -> memory ICs -> semiconductors. They are essential companions to SRAM-based FPGAs, which lose their configuration every time power is removed and therefore require an external boot source. Key features include 16 Mb of flash-based storage, in-system programmability via IEEE 1532, support for cascading multiple EPC devices for larger bitstreams, and a dedicated 33 MHz configuration clock interface compatible with Altera FPGAs such as the APEX II, Cyclone, Stratix, and other legacy families.

The Altera (now Intel) EPC16QI100T is a 16-Mbit enhanced configuration device (PROM) designed to configure SRAM-based LUT FPGAs such as Stratix, APEX II, APEX 20K, Mercury, ACEX 1K, and FLEX 10K devices. Housed in a 100-pin Plastic Quad Flat Pack (PQFP) measuring 20x14 mm and shipped on Tape and Reel (suffix T), it provides single-device, high-speed, advanced configuration support for very high-density Altera FPGAs. A configuration PROM (Programmable Read-Only Memory) is a non-volatile flash memory that stores the bitstream image of an FPGA. At FPGA power-up, the PROM loads the bitstream serially or in parallel into the FPGA's SRAM configuration cells, defining the FPGA's logic, routing, and I/O behavior. Enhanced configuration devices divide the silicon into two blocks: a configuration controller that manages the FPGA handshake (nSTATUS, CONF_DONE, nCONFIG) and a flash memory array that holds the bitstream. Key features include 16 Mbit of flash memory, compression support that lets a smaller PROM hold a larger FPGA bitstream (decompression happens in the FPGA), in-system programmability via IEEE 1149.1 JTAG, page-mode configuration for fast multi-device daisy chains, and 3.3V single-supply operation. The device uses the Altera EPC16 controller IP and supports both serial and parallel (8-bit) configuration data widths depending on FPGA connection mode. Architecturally, the EPC16QI100T combines a flash core, a configuration state machine, JTAG TAP controller, and I/O buffers. The compression feature reduces external storage requirements; a 16 Mb PROM can effectively configure FPGAs whose uncompressed bitstreams exceed 16 Mb because the data is compressed in the PROM and decompressed by the FPGA's built-in decoder. Typical applications include factory programming of Stratix-series FPGA prototypes, OEM production boards using ACEX 1K and FLEX 10K designs, industrial controller platforms, and any legacy Altera FPGA-based system that requires non-volatile boot storage. It is also used in military and aerospace retrofits where original configuration PROMs have aged out. When designing with this part, ensure the FPGA's configuration mode (serial vs parallel) matches the PROM's data-width interface. Verify JTAG chain ordering when the PROM shares the JTAG bus with the FPGA, and observe VCC ramp-time limits during power-up sequencing.

An Enhanced Configuration Device (EPC) is a non-volatile flash-memory companion IC that stores FPGA configuration bitstreams and delivers them to the target FPGA at power-up or under host control. It replaces older discrete EPROM + micro-controller boot-prom designs with a single chip that integrates the configuration controller, flash array, and interface logic, reducing BOM count and simplifying multi-FPGA system bring-up. Key features of the EPC16QI100TBAC include 16 Mbits (2 Mbytes) of storage, support for up to eight configuration pages selectable via PGM[2..0] pins, dynamic in-system reconfiguration, 3.3V single-supply operation, and a 100-pin PQFP package. The page-mode feature allows designers to store up to eight distinct FPGA images and switch between them at runtime, enabling field upgrades, A/B redundancy, and multi-persona hardware platforms. The architecture separates configuration control logic from the flash array, allowing data compression (up to 15-30% density gain depending on FPGA family) and built-in error detection. The IC supports JTAG (IEEE 1149.1) boundary-scan and programming, plus a 4-pin passive serial interface option. Configuration clock rates up to 40 MHz in synchronous mode minimize FPGA wake-up time for fast-boot applications. Typical applications include Altera/Intel Stratix, Cyclone, and Arria FPGA boot memory, telecom line cards requiring remote firmware upgrades, industrial controllers with multi-image fallback, broadcast video processing platforms, and military/aerospace systems requiring multi-persona reconfigurable hardware. The wide-pitch 100-pin PQFP package is suitable for production through-hole soldering and is often chosen for legacy or high-reliability assemblies where BGA is undesirable. When designing with the EPC16QI100TBAC, ensure the 3.3V supply rail is decoupled with 0.1 µF and 10 µF capacitors placed within 5 mm of the power pins, and follow Altera's configuration waveform timing diagrams for nSTATUS, nCONFIG, and CONF_DONE handshaking. For multi-page designs, allocate PGM[2..0] to GPIO outputs on a host MCU or CPLD to allow runtime page selection. The IC is rated for the industrial temperature range and is lead-free.

EPC16SI16N

EPC16SI16N - 16Mb Enhanced Configuration Device, 16-SOIC | Altera / Intel

The Intel (Altera) EPC16SI16N is a 16-Mbit enhanced configuration device supplied in a 16-pin SOIC package, designed to store and deliver configuration bitstreams to Altera SRAM-based FPGAs such as the Stratix II and Cyclone series. It provides 16 Mb of non-volatile flash memory, supports the enhanced serial (FAST passive parallel-style) configuration interface, and operates from a single 3.3 V supply with an industry-standard 4-wire serial interface plus dedicated configuration control pins (nCS, nRESET, nSTATUS, DCLK, DATA). An enhanced configuration device (EPC family) is a specialized flash-memory IC whose sole function is to retain FPGA configuration bitstreams between power-cycles so that an SRAM-based LUT FPGA can self-load at power-up. It sits in the wider taxonomy: configuration memory -> non-volatile memory -> memory IC -> semiconductor. Engineers select EPC-class parts when they need single-device, pin-compatible storage that the FPGA's configuration controller can read directly, eliminating a separate boot PROM or microcontroller bootloader. Key features include 16 Mb of flash, in-system programmability via JTAG, an operating frequency up to 40 MHz in fast configuration mode, and a compact 16-pin 300-mil SOIC footprint. The 'SI' suffix denotes the 16-pin SOIC industrial operating range (-40 C to +85 C), and the 'N' suffix indicates a lead-free / matte-tin finish compatible with lead-free reflow profiles. Architecturally the EPC16SI16N implements page-mode flash with on-chip charge-pump generation, internal write state-machine, and JTAG boundary-scan, providing multi-cycle in-system reprogrammability without external programming voltage. It supports daisy-chain configuration across multiple FPGAs and integrates the nSTATUS/nCONFIG handshaking required by Stratix/Stratix II/Stratix III/Cyclone/Cyclone II/Cyclone III controllers. Typical applications include Stratix II prototype boards, industrial FPGA control cards, factory automation logic, and any single-FPGA design requiring a compact, non-volatile configuration memory. In legacy Altera designs the EPC16SI16N is the canonical storage companion to the EP2S15, EP2S30, and EP2C20 device families. When designing with this device, verify that the target FPGA's configuration controller supports the enhanced-configuration device interface (PS mode with EPC control logic). PCB layout should keep DCLK traces short and add a 0.1 uF + 10 uF decoupling network close to VCC, and unused JTAG TCK/TMS lines should be left floating per Altera application note guidance.
