EPC1441LC20 - 440 kb FPGA Configuration PROM | Altera | FPGA
Altera EPC1441LC20 is a 440 kb, one-time-programmable configuration PROM for SRAM-based FPGA and LUT devices, with a stated 8 MHz configuration-related performance figure and a 20-pin PLCC package measuring 9 mm by 9 mm. According to the supplied distributor and manufacturer-data references, the device provides nonvolatile storage used to reload configuration data when an FPGA powers up, when the system initializes, or when new configuration data is required. It is an integrated-circuit memory device in the configuration-PROM category and is associated with a 0 °C to 70 °C commercial temperature range in the supplied search data.
A configuration PROM is a specialized nonvolatile memory IC that stores the bitstream required by an SRAM-based programmable logic device. Because SRAM-based FPGAs lose their logic configuration when power is removed, the configuration controller reads the PROM during startup and transfers the stored data to the target device. The hierarchy is configuration PROM -> nonvolatile memory -> FPGA configuration memory -> FPGA and CPLD support component. EPC1441LC20 belongs to Altera’s EPC14 configuration-device family, historically used for SRAM-based LUT devices.
The principal identified feature is 440 kb of configuration memory, supplied in a 20-PLCC (9x9) package. Search references identify an 8 MHz configuration-memory performance value, while one distributor listing describes the device as a serial configuration memory. The one-time-programmable nature allows the configuration image to be stored before system operation, after which the PROM can provide the startup bitstream without a separate external programming port during normal operation. These characteristics make the part relevant to legacy FPGA boards, replacement systems, and designs requiring deterministic configuration storage.
In a typical design, the EPC1441LC20 is connected to the FPGA configuration interface and selected during the device’s configuration cycle. The FPGA configuration controller reads the serial data and writes it into the SRAM-based logic fabric. The 8 MHz figure is a useful system-level timing reference, but the final configuration time depends on the target FPGA, interface mode, PROM setup, board loading, and controller behavior. Engineers should therefore use the complete device documentation and target-FPGA configuration timing information rather than treating the PROM figure as the only end-to-end timing value.
Common applications include SRAM-based FPGA configuration, industrial control equipment with legacy Altera devices, communications or test equipment using programmable logic, and board-level replacement or repair. The 20-pin PLCC package is important for legacy footprints and should be checked against the PCB land pattern and pin numbering before procurement. Commercial-temperature operation from 0 °C to 70 °C is explicitly reported in the supplied Kynix listing, but voltage, current, interface voltage, programming procedure, and absolute maximum ratings require confirmation from the manufacturer datasheet.
For new designs, verify whether the FPGA can use a compatible configuration source, whether the EPC1441LC20 has sufficient capacity for the generated bitstream, and whether the board provides the required reset, configuration-clock, data, and handshake signals. The package and pinout must be cross-checked against the original design and the latest manufacturer documentation. Pricing and availability are time-sensitive; the supplied distributor search result states “Buy now, ships today,” but current stock and lead time should be confirmed with the distributor before release to production.
This product data combines verified web specifications, package and temperature information, pricing availability signals, application context, and engineering considerations. It is intended to support component selection, legacy-board maintenance, and informed sourcing while marking unverified electrical characteristics as data-needed rather than guessing them.
