EPM9400RC240-20 概要

The Altera EPM9400RC240-20 is a 400-macrocell (MC), 20 ns pin-to-pin delay member of the MAX 9000 family of high-performance CMOS EEPROM-based Complex Programmable Logic Devices (CPLDs), housed in a 240-pin RQFP (32x32 mm) package with exposed thermal pad. It operates from a single 4.75 V to 5.25 V supply and is part of the MAX architecture that integrates multiple Logic Array Blocks (LABs) interconnected by the third-generation Multiple Array MatriX (MAX) programmable interconnect, delivering high-density glue-logic integration with predictable timing.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the deterministic timing of PAL/PLA architecture with the integration scale of a small FPGA, making it ideal for address decoding, bus interface, state-machine, and control-logic functions. Within the broader taxonomy, a CPLD belongs to programmable logic devices (PLD) -> logic ICs -> integrated circuits, and complements SRAM-based FPGAs by providing instant-on non-volatile configuration with high I/O counts at low power.

Key features of the EPM9400RC240-20 include 400 macrocells distributed across LABs, 5.0-V in-system programmability (ISP) via a built-in IEEE Std. 1149.1 JTAG interface, 20 ns tPD (pin-to-pin delay), and an I/O count consistent with the 240-RQFP pinout. The 5-V tolerant I/Os interface directly with TTL and CMOS logic, and the device supports JTAG boundary-scan testing per IEEE 1149.1 for board-level testability. Non-volatile EEPROM cells retain configuration without an external boot PROM.

The MAX 9000 architecture combines a programmable interconnect, dedicated input registers, and configurable I/O cells, enabling designers to implement wide combinatorial and registered logic functions. The third-generation MAX matrix reduces interconnect delay variance compared with first-generation MAX devices, allowing deterministic timing closure across wide logic blocks. A global clear and per-macrocell clocking network simplify sequential designs and clock-domain control.

Typical applications include address decoding and bus-interface logic for embedded processors, peripheral glue logic between microcontrollers and external memories, industrial control boards, and legacy 5-V system upgrade paths where non-volatile instant-on logic is required. The 240-RQFP package provides ample I/O for wide datapath and address-bus interfaces typical of 8/16/32-bit embedded designs.

When designing with the EPM9400RC240-20, ensure the 5 V supply rails rise monotonically per the Operating Requirements for Altera Devices Data Sheet. Inputs may undershoot to -2.0 V or overshoot to 7.0 V only for periods shorter than 20 ns under no-load conditions; DC input must remain within -0.5 V on I/O pins and -0.3 V on the four dedicated input pins. A JTAG chain must observe TCK/TMS/TDO/TDI ordering if multiple 1149.1 devices are present.

This page synthesizes distributor pricing, drop-in alternatives from the same MAX 9000 family, and practical design notes that go beyond the manufacturer datasheet, including JTAG programming guidance and supply-rail monotonicity requirements for robust in-system programming.

EPM9400RC240-20 の用途: 6 件s: Address Decoding and Bus Interface Logic, Industrial Control and PLC Logic, Legacy 5 V System Upgrade Paths, Peripheral Glue Logic for Microcontrollers, JTAG Boundary-Scan Test Integration, Telecommunications Backplane Glue Logic.

🔧

Address Decoding and Bus Interface Logic

The EPM9400RC240-20's 400 macrocells and 240 I/O pins make it well suited for address-decoding and bus-interface glue logic in 5 V embedded systems, including ISA, PC/104, and custom 8/16/32-bit microprocessor buses. Its 20 ns tPD comfortably meets typical memory and peripheral chip-select timing budgets, while the deterministic MAX interconnect provides consistent propagation delay across all I/O pins. Programmed via JTAG ISP, the device can be reconfigured on the board during prototyping without removing the part, accelerating firmware bring-up.

🏭

Industrial Control and PLC Logic

In industrial control boards and PLCs, the EPM9400RC240-20 provides deterministic non-volatile glue logic that retains configuration through power cycles without an external boot PROM. Its 5 V tolerant I/Os interface directly with industrial 5 V logic families, and the 240-RQFP package provides ample I/O for sensor multiplexing, relay drive control, and encoder interface. The third-generation MAX interconnect reduces signal-integrity concerns on long PCB traces, while EEPROM configuration eliminates boot-time delays inherent to SRAM-based FPGAs.

✈️

Legacy 5 V System Upgrade Paths

The EPM9400RC240-20 is widely used in legacy 5 V system upgrades where newer 3.3 V CPLDs cannot interface directly with 5 V logic. Its 4.75 V to 5.25 V supply range matches TTL/CMOS 5 V rails, and the EEPROM-based non-volatile configuration ensures instant-on behavior at power-up - critical for safety-sensitive or time-deterministic embedded applications. Designers of medical, aerospace, and military systems often select this part for long-life-cycle products where field-proven reliability matters more than modern feature density.

🖥️

Peripheral Glue Logic for Microcontrollers

When interfacing microcontrollers to external peripherals (DRAM, FPGAs, ADCs, DACs), the EPM9400RC240-20 handles custom timing, bus-format conversion, and chip-select generation in a single non-volatile device. The 400 macrocells can absorb entire state machines and bus-multiplexing logic that would otherwise consume many discrete TTL packages, reducing BOM cost and PCB area. JTAG ISP allows firmware engineers to update peripheral timing without removing the part, simplifying late-stage design changes.

🧩

JTAG Boundary-Scan Test Integration

The built-in IEEE Std. 1149.1 JTAG interface of the EPM9400RC240-20 enables seamless boundary-scan integration on boards using JTAG for manufacturing test. The part supports JTAG chain inclusion alongside other 1149.1-compliant devices, allowing shared TCK/TMS routing and a unified BSDL test pattern. The 240-RQFP package brings dedicated JTAG pins and four dedicated input pins, simplifying chain design while preserving I/O flexibility for application logic.

🌐

Telecommunications Backplane Glue Logic

In telecom backplanes and access-network equipment, the EPM9400RC240-20 implements line-card interface logic, clock-distribution control, and alarm-handling state machines with predictable 20 ns timing. Its non-volatile configuration eliminates boot-time variability, essential for carrier-grade equipment requiring fast restart after power events. The 240-RQFP footprint provides sufficient I/O for 16-bit data buses plus extensive control signals typical of T1/E1 and DSLAM architectures.

What is the EPM9400RC240-20?
The EPM9400RC240-20 is a 400-macrocell, 20 ns pin-to-pin delay member of the Altera MAX 9000 family of EEPROM-based CPLDs, supplied in a 240-pin RQFP package (32x32 mm) with an exposed thermal pad. It operates from a single 4.75 V to 5.25 V supply and supports 5.0-V in-system programmability through a built-in IEEE Std. 1149.1 JTAG interface, making it a classic high-density 5-V glue-logic device for embedded designs.
What is the macrocell count and pin-to-pin delay of the EPM9400RC240-20?
The EPM9400RC240-20 integrates 400 macrocells (encoded as '400MC' in the MPN suffix) with a 20 ns tPD (pin-to-pin delay). According to the MAX 9000 datasheet, this combination delivers deterministic timing suitable for address decoding, bus arbitration, and high-frequency state-machine logic in 5 V embedded systems.
What supply voltage does the EPM9400RC240-20 require?
The EPM9400RC240-20 requires a single 4.75 V to 5.25 V supply (5 V nominal). The Operating Requirements for Altera Devices Data Sheet mandates that VCC rise monotonically during power-up to ensure reliable ISP operation; input DC levels must remain within -0.5 V (I/O) and -0.3 V (four dedicated inputs) for continuous operation.
Where can I download the EPM9400RC240-20 datasheet PDF?
The EPM9400RC240-20 datasheet is published by Altera (now Intel) as part of the MAX 9000 Device Family datasheet, available at intel.com/content/dam/www/programmable/us/en/pdfs/literature/ds/m9000.pdf. Mirrored copies also appear on DigiChip and distributor product pages; the datasheet contains macrocell tables, timing specifications, and 240-RQFP pinout.
What is the pinout of the EPM9400RC240-20?
The EPM9400RC240-20 uses the 240-pin RQFP (32x32 mm) package with exposed thermal pad. Pin assignments are defined in the MAX 9000 datasheet section covering the 240-pin RQFP pin-out table, including dedicated JTAG pins (TCK, TMS, TDI, TDO), four dedicated input pins, I/O banks, and power/ground pins. Pin 1 orientation follows the standard RQFP top-left marker convention.
Is the EPM9400RC240-20 still in production or obsolete?
The EPM9400RC240-20 is currently classified as NRND (Not Recommended for New Designs) per Altera/Intel product lifecycle status. Distributors including Heisener, Nantian, and Xecor still list stock as of 2026-09-13; the part is supported by Altera/Intel but no longer recommended for new designs - new designs should evaluate MAX II or MAX V CPLDs as replacements.
Where can I buy the EPM9400RC240-20 and what is the price?
The EPM9400RC240-20 is available through authorized distributors including DigiKey, Heisener, Nantian, Xecor, QTreeic, and Octopart-listed suppliers. Heisener reports in stock and QTreeic lists 2,129 pieces as of 2026-09-13; unit pricing requires a quote for 1-piece breaks but typical 100-piece pricing ranges near USD 29-33, declining to approximately USD 23-26 at 1000 pieces.
What is the lead time for the EPM9400RC240-20?
Lead time for the EPM9400RC240-20 is reported as immediate shipment by Heisener (Sep 9 - Sep 14 delivery window, as of 2026-09-13). Stock is also available at Nantian, QTreeic, and several other distributors; for large production volumes, requesting a quote directly from authorized Intel/Altera channels is recommended to confirm availability.
What is the difference between EPM9400RC240-20 and EPM9400RC240-15?
The EPM9400RC240-20 has a 20 ns pin-to-pin delay (tPD), while the EPM9400RC240-15 has a faster 15 ns tPD. Both share the same 400 macrocells and 240-RQFP (32x32 mm) package, so they are pin-compatible drop-in alternatives - choose the -20 for cost-sensitive designs and the -15 when a tighter timing budget is required, with no PCB changes.
Can EPM9400RC240-15 replace EPM9400RC240-20 directly?
Yes, the EPM9400RC240-15 is a direct drop-in replacement for the EPM9400RC240-20 on the same 240-RQFP footprint. Both parts have 400 macrocells, identical I/O count, and identical power/ground pin assignments; the only difference is 15 ns vs 20 ns tPD, meaning the -15 is functionally faster and interchangeable in any 240-RQFP design.
What is the best drop-in replacement for EPM9400RC240-20?
The best drop-in replacement for EPM9400RC240-20 in the same 240-RQFP package is the EPM9400RC240-15 (same 400 macrocells, 240-RQFP, only tPD differs). For applications where 5-V tolerance is not required, MAX II or MAX V CPLDs are recommended for new designs; however, they require a different package footprint and are not pin-compatible drop-ins.
EPM9400RC240-20 vs EPM9320RI208-20 - which is better for my design?
The EPM9400RC240-20 has 400 macrocells and 240 pins, while the EPM9320RI208-20 has 320 macrocells and 208 pins. Choose EPM9400RC240-20 when you need the higher macrocell count and larger I/O budget for wide datapath interfaces; choose EPM9320RI208-20 when a smaller 208-pin RQFP footprint and 320 macrocells are sufficient. Both are MAX 9000 family, 5 V, JTAG-ISP parts.
What is the difference between MAX 9000 and MAX II CPLDs?
MAX 9000 is a 5 V EEPROM-based CPLD family with macrocell counts up to 560, while MAX II is a 3.3 V (with 5 V tolerant I/O options) SRAM-based CPLD family using look-up tables (LUTs) and non-volatile flash configuration memory. MAX II consumes less power and is recommended for new designs, but uses a different package footprint and is not pin-compatible with MAX 9000.
How is the EPM9400RC240-20 programmed in-system?
The EPM9400RC240-20 is programmed in-system via the built-in IEEE Std. 1149.1 JTAG interface, which connects TCK, TMS, TDI, and TDO to a JTAG programmer or download cable (ByteBlaster, MasterBlaster, USB-Blaster compatible). VCC must rise monotonically during programming; the JTAG chain supports read-back of EEPROM configuration for verification and boundary-scan testing per IEEE 1149.1.
What are the key specifications of EPM9400RC240-20 that engineers should know?
The key specifications of EPM9400RC240-20 are: 400 macrocells, 20 ns pin-to-pin delay (tPD), 4.75 V to 5.25 V single supply, IEEE 1149.1 JTAG in-system programmability, EEPROM non-volatile configuration, 240-RQFP (32x32 mm) package with exposed thermal pad, third-generation MAX interconnect architecture, and surface-mount mounting. The part is classified NRND but remains in distributor stock as of 2026-09-13.

選定ガイド

Choose the EPM9400RC240-20 when you need a 5 V-tolerant, 400-macrocell CPLD with JTAG in-system programmability in a 240-RQFP package for legacy or industrial 5 V designs. Choose the EPM9400RC240-15 when the same 240-RQFP footprint is acceptable and a faster 15 ns tPD tightens the timing budget (drop-in replacement on existing PCBs). Choose the EPM9400RC208-20 when you need 400 macrocells in a smaller 208-RQFP package (different footprint, not drop-in). Choose EPM9320RI208-20 for lower-density MAX 9000 designs with 320 macrocells in 208-RQFP. For new designs, evaluate MAX II or MAX V CPLDs as modern alternatives, noting they require a different PCB footprint and are not pin-compatible with MAX 9000.

設計ノート

The EPM9400RC240-20 requires a single 5 V supply (4.75 V to 5.25 V). Per the Operating Requirements for Altera Devices Data Sheet, VCC must rise monotonically during power-up to ensure reliable ISP operation. Inputs may undershoot to -2.0 V or overshoot to 7.0 V only for periods shorter than 20 ns under no-load conditions. DC input levels must remain within -0.5 V on I/O pins and -0.3 V on the four dedicated input pins. Decoupling: place 0.1 uF ceramic capacitors close to every VCC/GND pair on the 240-RQFP package to suppress switching noise.

Route JTAG signals (TCK, TMS, TDI, TDO) as a clean daisy chain if multiple 1149.1 devices share the same JTAG bus. Keep JTAG traces short and isolated from switching signals; add 10 kohm pull-ups on TMS and TDI to prevent spurious test-mode entry. The exposed thermal pad on the 240-RQFP must be soldered to a ground plane for mechanical stability and thermal dissipation, even though the MAX 9000 family is CMOS-low-power.

Do not assume the EPM9400RC240-20 is still recommended for new designs - it is classified NRND by Altera/Intel. For new designs, evaluate MAX II or MAX V CPLDs, which offer lower power and modern features but require a different PCB footprint (not pin-compatible). Also, when migrating an existing design to the EPM9400RC240-15 (faster 15 ns tPD), verify the Quartus II/MAX+PLUS II timing simulation still meets all setup/hold requirements under worst-case conditions.
