EPF6024AQI208-2N - FLEX 6000 24K Gate FPGA, PQFP-208 | Altera
MPN: EPF6024AQI208-2N ✗ Akhir HidupEPF6024AQI208-2N Ringkasan
A FLEX 6000 device is a fine-grained reprogrammable logic IC that sits between a complex programmable logic device (CPLD) and a high-density field-programmable gate array (FPGA) in the broader programmable logic hierarchy (CPLD -> FLEX 6000 -> FPGA -> SoC FPGA). The FLEX 6000 family was Altera's first Optically reprogrammable, low-cost, SRAM-based FPGA line optimized for high I/O count glue logic and data-path applications. Compared with CPLDs, the FLEX 6000 offers higher register density and richer routing; compared with modern FPGAs, it provides simpler development but lower logic capacity.
The EPF6024AQI208-2N delivers 171 configurable I/O lines plus 4 dedicated inputs, supporting a wide range of I/O standards including 3.3 V LVCMOS/LVTTL on the I/O banks. The maximum toggle performance of 153 MHz makes it suitable for mid-speed peripheral controllers, bus bridges, and state-machine replacement. Its high I/O count relative to its logic capacity makes it ideal for I/O-intensive glue-logic designs rather than DSP-heavy workloads.
Internally, the FLEX 6000 architecture combines Look-Up Tables (LUTs) for combinational logic with dedicated register cells, interconnected by a continuous FastTrack routing matrix. The device uses SRAM configuration cells, meaning configuration is volatile and must be reloaded from external non-volatile memory (typically an EPC configuration EPROM) on every power-up via the Altera passive serial (PS) or passive parallel asynchronous (PPA) configuration scheme.
Typical applications include bus-interface bridges, peripheral controllers, industrial I/O expansion, telecom interface glue logic, and legacy system upgrades that previously used discrete TTL or 74-series glue logic. The 208-pin PQFP package provides a fine-pitch (0.5 mm) surface-mount footprint with gull-wing leads, simplifying PCB assembly on standard reflow profiles.
When designing with the EPF6024AQI208-2N, ensure a stable 3.3 V core supply with proper decoupling, and always pair the FPGA with a configuration memory (EPC2, EPC4, or compatible). JTAG boundary-scan is supported via the 4-wire IEEE 1149.1 interface, enabling in-system programming (ISP) and post-assembly verification.

Aplikasi Umum
EPF6024AQI208-2N cocok untuk 6 aplikasis: Legacy Bus Interface Bridge, Industrial I/O Expansion, Peripheral Controller / State Machine Replacement, Telecom Line-Card Glue Logic, Test & Measurement Front-End, Embedded System Memory Controller.
Legacy Bus Interface Bridge
The EPF6024AQI208-2N is well suited to legacy bus-interface bridge designs where a microprocessor or microcontroller needs to interface between two mismatched parallel buses (for example, ISA-to-local-bus, PC/104-to-memory, or proprietary 8/16-bit peripheral bus conversion). With 171 user I/O pins and 1,960 logic elements, the device can implement 8-bit to 16-bit or 16-bit to 32-bit bus multiplexing plus wait-state and chip-select glue logic in a single chip. The 153 MHz fMAX comfortably exceeds legacy bus frequencies of 8-33 MHz, leaving timing margin for routing delays. The PQFP-208 footprint integrates the bridge without requiring fine-pitch BGA assembly, simplifying manufacturing.

Industrial I/O Expansion
In industrial control cabinets and PLC backplanes, the EPF6024AQI208-2N provides 171 user I/O lines that can be configured as LVCMOS/LVTTL inputs or outputs to scan switches, drive relays, and buffer sensor signals. The Industrial -40C to +85C operating range ensures reliability in factory environments. Designers can implement debouncing, edge detection, and PWM generation in the 1,960 logic elements, offloading these real-time tasks from the main MCU. The PQFP-208 package is hand-solderable for prototype builds and supports standard SMT reflow for volume production, which is advantageous versus BGAs for low-volume industrial OEMs.

Peripheral Controller / State Machine Replacement
Engineers replacing dozens of 74-series TTL/CMOS glue-logic packages with a single PLD can use the EPF6024AQI208-2N to consolidate complex state machines, FIFOs, and protocol converters. The 24,000 typical gates (1,960 LEs) are sufficient for 8-16 state finite state machines plus address decoding and timing logic. Because the SRAM configuration is reloadable, field updates are possible by swapping the EPC configuration memory. The 153 MHz internal fMAX supports UART (115.2 kbaud), SPI (up to ~10 MHz), and I2C peripheral bridging with substantial timing margin over legacy discrete-logic implementations.

Telecom Line-Card Glue Logic
In legacy TDM telecom line cards and backplane controllers, the EPF6024AQI208-2N provides framing, alarm scanning, and serial-to-parallel conversion for E1/T1 or H.110 bus interfaces. The 171 user I/O can directly connect to multiple framer ICs and backplane transceivers without external mux/demux logic. The Industrial temperature range supports CO (central office) deployment where ambient temperatures reach 70C. Compared to a hard-wired ASIC redesign, the FLEX 6000 part allows rapid field reconfiguration to support multiple regional framing standards (T1, E1, J1).

Test & Measurement Front-End
Test instruments such as logic analyzers, protocol exercisers, and bench-top data acquisition units use the EPF6024AQI208-2N for pattern generation, channel multiplexing, and timing/sequencing logic. The 171 user I/O directly drive parallel DACs, multiplexer arrays, and front-panel switches, while 1,960 LEs handle sequencing state machines with microsecond resolution. Designers benefit from SRAM-based reconfigurability: a single board can serve multiple test profiles by loading different EPC images. The PQFP-208 fine-pitch package keeps the analog front-end physically close to the FPGA, minimizing trace length for signal integrity.

Embedded System Memory Controller
As an SDRAM or SRAM controller in embedded systems, the EPF6024AQI208-2N provides the address multiplexing, chip-select decoding, and refresh timing required to bridge a 32-bit processor bus to standard memory devices. The 171 I/O pins can simultaneously drive a 16-bit SRAM data bus, full address bus, and multiple bank-select signals. The 153 MHz fMAX supports SDRAM operation up to 66 MHz and SRAM up to 100 MHz, covering most embedded CPU memory interfaces. Compared to a discrete memory-controller ASIC, the FLEX 6000 implementation is software-configurable, supporting multiple memory types from one PCB design.

Catatan Desain
The EPF6024AQI208-2N requires a stable 3.3 V VCCINT supply with decoupling of at least 0.1 uF and 10 uF ceramic capacitors near every VCCINT/GND pair (pins 3/6, 19/22, 35/38, etc.). The I/O banks also require a separate VCCIO rail at 3.3 V; if 5 V inputs are present, use external series resistors or level shifters. Estimated core current draw for a fully-utilized design at 100 MHz is approximately 50-100 mA; design the regulator with at least 30% headroom. During configuration, the FPGA pulls transient current bursts up to 200 mA - bulk decoupling on the 3.3 V rail is recommended.
The PQFP-208 package has a 0.5 mm lead pitch, requiring PCB land patterns designed per IPC-7351 guidelines with proper solder mask slivers. Maintain at least 4 oz copper on power planes for VCCINT/VCCIO to handle switching currents. Keep configuration clock (DCLK) trace length under 50 mm and route it away from high-speed switching signals to avoid jitter-induced configuration errors. Provide a ground plane directly under the device for thermal dissipation; the PQFP-208 has a typical theta_JA of approximately 25-30 C/W in still air, but adequate copper pours are still required.
Estimated power-on configuration timing: the FLEX 6000 device enters configuration mode within 5 us of nCONFIG rising; ensure the host controller or EPC memory holds nSTATUS high during this window. A common mistake is leaving the nCONFIG pin floating - this can cause intermittent configuration failures. Always tie nCONFIG to VCCIO through a 10 kohm resistor if not actively driven. Also verify CONF_DONE has a proper pull-up (typically 10 kohm to VCCIO) - without it, the host cannot detect successful configuration completion.
Separate analog and digital ground returns where possible; the 171 user I/O switching edges create ground bounce that can couple into adjacent sensitive analog inputs. Series-terminate output traces longer than 50 mm with a 33-ohm resistor to control overshoot. Place the EPC configuration memory in the same quadrant as the FPGA to minimize DCLK skew. JTAG chain integrity requires TCK termination to ground near the FPGA and short TCK-to-TDI/TMS trace stubs (under 5 mm) to avoid ringback on the scan chain.
