EP20K200BC356-1 - APEX-20K 200K-Gate FPGA | Altera
MPN: EP20K200BC356-1 ✗ Cuối đờiEP20K200BC356-1 Tóm tắt
An FPGA is an integrated circuit whose logic fabric can be configured after manufacture. Devices in the APEX-20K series integrate look-up-table logic and embedded memory on the same die, making them programmable logic devices (PLDs) positioned between CPLDs and ASICs in the semiconductor hierarchy. This was one of Altera's early families to advertise system-on-a-programmable-chip (SOPC) integration with dense routing resources.
The headline specifications are 8320 logic elements, 106496 RAM bits, 277 user I/Os and a 250 MHz -1 speed grade. The part is manufactured in 0.22 um CMOS and operates from a 2.5 V core supply. The 356-ball BGA package provides a compact surface-mount solution for board-level designs that need substantial glue logic, wide-bus decoding, state machines and small FIFOs without external logic parts.
From a silicon architecture standpoint, APEX-20K devices combine LUT-based logic with embedded memory blocks. The 106496 RAM bits can be used for small packet buffers, line-rate FIFOs, register files, or lookup tables, reducing component count in legacy designs. The 277 user I/Os can serve parallel busses and memory interfaces. The -1 speed-grade variant is the faster standard grade offered for this package; related speed-optimized and lead-free versions exist in the same 356-BGA footprint.
The primary applications are legacy industrial controllers, telecom line-card glue logic, video-processing controls, and military/aerospace sustainment programs where the original APEX-20K design must be reproduced without a PCB redesign. Because the device is obsolete, procurement should go through Rochester Electronics or an authorized surplus distributor rather than Intel/Altera direct.
One key design consideration is configuration storage: this SRAM-based FPGA must be configured from an external EEPROM/FLASH device or JTAG controller at every power-up. Also, since -2 or -3 speed-grade variants are slower, timing margins must be re-evaluated before substituting a slower speed grade into a design intended for 250 MHz operation.
This page synthesizes distributor pricing, drop-in same-family alternatives, practical design notes, and compliance markers not found on the original manufacturer datasheet, so engineers can quickly make sourcing and replacement decisions for this obsolete FPGA.

Ứng dụng tiêu biểu
EP20K200BC356-1 phù hợp cho 6 Áp dụngs: Legacy Industrial Control and Motion Logic, Telecom and Line-Card Bridging, Video and Image Processing Control, Defense and Aerospace Legacy Sustainment, Medical Instrument I/O Bridging, Obsolete FPGA Replacement and Refurbishment.
Legacy Industrial Control and Motion Logic
The EP20K200BC356-1 fits legacy industrial controller boards because it provides 8320 logic elements and 277 user I/O pins for wide bus decoding, parallel glue logic, encoder counters, PWM generation and custom timing state machines. Its APEX-20K embedded memory of 106496 bits can replace external SRAM for small FIFOs and lookup tables in older designs. The 2.5 V core matches late-1990s/2000s industrial modules, allowing reuse of existing power rails rather than adopting a high-density new FPGA. At 250 MHz, the -1 speed grade is usually sufficient for 10-50 MHz industrial clocks. For RoHS rework, select the EP20K200BC356-1N variant; for timing-critical paths, EP20K200BC356-1X can offer extra clock margin in the same physical footprint.

Telecom and Line-Card Bridging
In telecom line cards, the EP20K200BC356-1 can perform address decoding, framer interfacing, control-plane protocol logic and serial-to-parallel conversion. Its 8320 logic elements are well suited to implement dozens of small state machines or time-division multiplexed channel handlers. The 277 user I/Os allow connection of wide parallel busses to framers and switch fabrics, while 106496 RAM bits provide a small shared memory for per-channel counters or FIFO status. The 250 MHz clock grade is useful for UTOPIA/POS-PHY and other legacy cell/packet interfaces. For a lead-free assembly, use the -1N or -1XN part; if the original design needs more timing margin, the -1X variant is a direct replacement in the same 356-ball BGA package.

Video and Image Processing Control
The EP20K200BC356-1 can act as a sync generator, frame-buffer address generator, or video timing controller when placed ahead of external SDRAM or VRAM. Its 8320 logic elements are enough for horizontal/vertical counters, blanking insertion and I2C-like configuration logic, while 106496 RAM bits can hold small line buffers or look-up tables for gamma correction. The 277 I/Os allow connection to an external video bus, microcontrollers and memory address/data buses in parallel. For standard-definition video clocks below 27 MHz, the -1 speed grade is generally adequate. Replacing a failed FPGA on an existing video board is straightforward because the 356-BGA footprint is identical across the -1/-1X/-1N/-1XN variants.

Defense and Aerospace Legacy Sustainment
Military and aerospace programs often need to sustain an original Altera APEX-20K FPGA design for 20+ years after production. The EP20K200BC356-1 provides 8320 logic elements, 277 user I/Os and 106496 RAM bits in a 356-BGA package that matches existing defense circuit cards. Because the part is obsolete, design-for-obsolescence strategies should include purchasing date-code-locked inventory and evaluating the lead-free EP20K200BC356-1N or EP20K200BC356-1XN when RoHS restrictions apply. The commercial temperature grade is normally 0 to 85 C, so a full military-temperature extension should be confirmed against the exact datasheet grade code used by the original program. Use Rochester Electronics or an approved supply chain partner to maintain traceability.

Medical Instrument I/O Bridging
In legacy medical imaging and patient-monitoring instruments, the EP20K200BC356-1 can bridge an embedded CPU bus to custom sensor interfaces, motor controllers, or display panels. Its 8320 logic elements allow implementation of bus timing, interrupt control, and device-select logic without adding a second CPLD. The 106496 RAM bits are useful for small parameter look-up tables or temporary command queues. The 277 user I/Os let the FPGA connect directly to 8/16-bit microcontrollers, ADCs, DACs, and parallel LCD interfaces. For RoHS-compliant medical equipment repairs, select the EP20K200BC356-1N variant; if the FPGA is required to provide faster internal clocking, the EP20K200BC356-1X version may be ordered in the same BGA package.

Obsolete FPGA Replacement and Refurbishment
For contract manufacturers and repair depots, the EP20K200BC356-1 is frequently used to refurbish boards in telecom, industrial and test equipment that cannot be redesigned. The 356-LBGA package is soldered directly onto the original board, so the replacement part must be the same APEX-20K device family and speed grade. The original non-N EP20K200BC356-1 is appropriate for SnPb rework, while EP20K200BC356-1N is preferred when lead-free assembly is required. The -1X and -1XN variants add speed margin and can be used as drop-in upgrades when timing is tight. Because this is a SRAM FPGA, the replacement device must be configured with the same bitstream; verify that the configuration device or JTAG chain is still functional.

Ghi chú thiết kế
EP20K200BC356-1 requires a 2.5 V core supply. Estimated: an 8320-logic-element device operating near 250 MHz can draw well over 1 A core current under high toggle; actual current should be obtained from an APEX-20K power calculator or a representative bitstream. Place 0.1 uF ceramic decoupling capacitors near each power ball and add 10-47 uF bulk capacitance on the 2.5 V rail. Keep the decoupling loop area small because 356-ball BGA vias add inductance to the power-delivery path.
The 356-ball BGA ball map must be taken from the APEX-20K Family datasheet; do not use generic BGA pinouts because power, ground, configuration, and user I/O ball assignments are device-specific. For clocks and high-speed parallel buses above 100 MHz, match trace lengths and provide solid ground return vias beneath the package. If the board uses vias-in-pad, confirm that the solder paste and stencil design are compatible with a 356-ball component during rework.
APEX-20K devices are supported by legacy Altera/Intel Quartus II device support, not by newer Intel Quartus Prime releases unless the legacy device support pack is installed. Keep the original project environment if you only need to regenerate a bitstream. Before substituting a -2 or -3 speed-grade variant into a board designed for the -1 EP20K200BC356-1, re-run timing closure because the slower guaranteed speed grade can fail a 250 MHz design.
Thông tin tuân thủ
The verified data does not list RoHS/REACH compliance for the non-N EP20K200BC356-1. N-suffix variants such as EP20K200BC356-1N/-1XN are generally identified as lead-free in Altera's ordering nomenclature. No AEC-Q100 data was found for this FPGA. For RoHS-required assemblies, use the N-suffix versions and confirm with the distributor's certificate of compliance.
