EPC144L120 - Altera/Intel EPC1441 Configuration Device 120-QFP
MPN： EPC144L120 ✗ 停產EPC144L120 概覽
A Configuration Device is a non-volatile (one-time-programmable, OTP) serial memory specifically architected to stream configuration data into an Altera FPGA during power-up. It connects to the host FPGA through a dedicated serial configuration interface (DATA, DCLK, nCONFIG, nSTATUS, CONF_DONE). Compared to a generic serial EEPROM, a configuration device adds FPGA-aware handshaking, automatic reconfiguration on bitstream error, and pin-level compatibility with Altera/Intel FPGA configuration controllers.
Key features of the EPC144L120 family include 100,000 (EPC1441 naming convention indicates density family; specific density bits to be confirmed from datasheet) configuration bits, a continuous-streaming serial interface, 3.3 V or 5 V tolerant I/O, and a QFP-120 (L120 suffix) plastic package for surface-mount assembly. Programming is performed once by Altera's software tools, after which the device retains the bitstream indefinitely without external supplies.
In a typical system, the EPC144L120 sits next to the target FPGA and is wired to its configuration pins. On power-up, the FPGA drives nSTATUS low, then the EPC144L120 clocks the bitstream out through DATA into the FPGA's configuration RAM. Engineers designing with this device should ensure proper decoupling on VCC and that the nINIT_CONF / nCONFIG pull-ups follow the Altera reference schematic, otherwise the device may fail to enumerate on cold start.

典型應用
EPC144L120 適用於 6 應用s: Legacy FLEX 10K FPGA Configuration, ACEX 1K FPGA Boot Memory, APEX 20K FPGA Configuration, Mercury-class FPGA Configuration, Industrial Control Systems with Altera Legacy FPGAs, Avionics / Defense Legacy Systems.
Legacy FLEX 10K FPGA Configuration
Boots FLEX 10K series FPGAs from a non-volatile bitstream on power-up. The EPC144L120 sits adjacent to the FLEX 10K device and streams the SRAM configuration image through its single-wire DATA pin under the FLEX 10K's native configuration controller handshaking (nCONFIG, nSTATUS, CONF_DONE). Its 100 kbit-class density is sufficient for FLEX 10K bitstreams, and the QFP-120 footprint integrates cleanly on legacy Altera evaluation boards that follow the original reference schematic. For long-life industrial products still running on FLEX 10K, the EPC144L120 remains a recognized configuration solution.
推薦
ACEX 1K FPGA Boot Memory
Provides the configuration bitstream for ACEX 1K series FPGAs in industrial control systems. The ACEX 1K's configuration controller is fully compatible with the EPC144L120's serial DATA/DCLK protocol, so the EPC144L120 can be wired directly to the FPGA's configuration pins with no glue logic. In factory automation and motor-control applications where ACEX 1K is still in service, the EPC144L120 offers the simplest path to retaining a non-volatile boot PROM. Designers should follow the Altera reference schematic for pull-ups on nCONFIG and nSTATUS.
推薦
APEX 20K FPGA Configuration
Streams the APEX 20K device bitstream at power-up. APEX 20K devices have larger configuration images than FLEX 10K, so the EPC144L120 is typically used for lower-density APEX 20K variants where the bitstream fits within the EPC1441 family's storage capacity. The APEX 20K's configuration controller handshakes with the EPC144L120 through the same DATA/DCLK/nCONFIG/nSTATUS/CONF_DONE bus as older FLEX devices, simplifying board design.
推薦
Mercury-class FPGA Configuration
Configures Altera Mercury-class FPGAs in high-speed signal-processing designs. Mercury FPGAs, used in communications and DSP applications, share the same Altera serial configuration interface as FLEX and APEX families. The EPC144L120's serial protocol is directly compatible, but the Mercury device's bitstream may require the larger-density EPC16 or EPC8 device for higher-bitstream-count designs.
推薦
Industrial Control Systems with Altera Legacy FPGAs
Stores the FPGA bitstream in long-life industrial controllers, machine vision, and test equipment that have used Altera FLEX/ACEX/APEX FPGAs for decades. Because the EPC144L120 is one-time programmable and retains the bitstream without external supplies, it provides high reliability in factory-floor applications. The QFP-120 package supports surface-mount assembly suited to high-volume production.
推薦
Avionics / Defense Legacy Systems
Maintains configuration for long-lifecycle defense and avionics platforms that use ACEX 1K or FLEX 10K FPGAs as approved components. Because the EPC144L120 is a one-time-programmable OTP memory, its bitstream is robust against accidental re-programming in fielded equipment. The QFP-120 footprint and Altera-qualified package make it suitable for systems requiring component pedigree and long-term supplier support.

主要差異化特點
- 120-pin QFP-120 package variant for high-pin-count designs (對比EPC1441PI8 (PDIP-8))
- Drop-in compatible with other EPC1441 QFP-120 variants (對比EPC1441L120W)
- Single-wire serial configuration interface for Altera legacy FPGAs (對比EPCQ (active-serial flash))
設計說明
Provide a clean 3.3 V supply to VCC with a 0.1 uF decoupling capacitor placed within 5 mm of the VCC pin. The EPC144L120 draws modest inrush current during configuration streaming; a 10 uF bulk capacitor near the device prevents VCC droop. According to Altera configuration device reference designs, nCONFIG and nSTATUS require pull-up resistors (typically 10 kohm) to VCC.
Place the EPC144L120 as close as practical to the target FPGA's configuration pins. Trace length on the DATA, DCLK, nCONFIG, nSTATUS and CONF_DONE signals should be kept under 50 mm to avoid signal-integrity issues during configuration. The QFP-120 package has a 0.5 mm pitch; follow IPC-7351 land pattern recommendations and use solder paste with Type 3 or finer powder for reliable reflow.
Do not confuse the EPC144L120 with the EPC1441PI8 (PDIP-8) variant when ordering - same silicon family, different packages. The EPC144L120 is NRND, so for new designs Intel recommends migrating to EPCQ or active-serial flash devices. Verify the target FPGA's bitstream fits within the EPC1441 family's storage capacity - for higher-density FPGAs such as APEX 20K400, an EPC8 or EPC16 device is required.
合規資訊
RoHS, REACH, lead-free, and halogen-free status could not be confirmed from the verified web data for the EPC144L120 specifically. The part is NRND per Intel/Altera's product page; designers should request the latest Material Declaration datasheet from the manufacturer.
