EPM9400RC240-15 概覽

The Intel (formerly Altera) EPM9400RC240-15 is a high-performance CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 9000 device family, providing 400 macrocells in a 240-pin RQFP (plastic quad flat pack) package with a 15 ns pin-to-pin propagation delay. The device operates at 5.0 V and supports in-system programmability (ISP) through a built-in IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface, enabling board-level reconfiguration without removing the part.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL/GAL-like logic blocks with a central interconnect matrix, providing deterministic, fast combinatorial and registered logic with predictable timing. Within the broader taxonomy, the EPM9400 sits in the MAX 9000 family, which is itself part of the Programmable Logic Device (PLD) hierarchy under the broader category of programmable logic semiconductors - bridging the gap between discrete 74-series logic and FPGA-class devices.

Key features of the EPM9400RC240-15 include 8,000 usable gates, 400 macrocells, a maximum operating frequency of approximately 117.6 MHz, and 5.0 V in-system programmability via JTAG. The MAX 9000 architecture uses Altera's third-generation Multiple Array MatriX (MAX) interconnect, providing fast, deterministic delays across all I/O paths regardless of logic placement.

The 15 ns speed grade is the middle of the MAX 9400 family - faster than -20 speed grade parts (20 ns) and slower than -10 grade. The 240-pin RQFP package provides a high pin count for I/O-intensive glue-logic applications, while the EEPROM process technology ensures non-volatile configuration that retains state across power cycles without external boot memory.

Typical applications include bus decoding and address mapping in industrial control systems, glue logic between microprocessors and peripherals, I/O expansion in legacy 5 V designs, and state-machine replacement in telecom backplane interfaces. The 5 V tolerance makes it ideal for legacy TTL interfaces that remain common in factory automation and instrumentation.

When designing with this part, verify that the I/O bank voltages match the system logic levels - the MAX 9000 family is optimized for 5 V rails and is not directly drop-in compatible with 3.3 V-only logic without level translation. Confirm JTAG chain order and TMS/TCK/TDO/TDI termination when chaining multiple ISP devices.

🏭

5V Bus Decoding and Address Mapping

The EPM9400RC240-15's 400 macrocells and 240-pin RQFP package make it ideal for 5 V bus decoding and address mapping in legacy industrial ISA, VME, and STD bus architectures. Its 15 ns pin-to-pin delay easily meets ISA bus cycle timing (250 ns per bus cycle) and its non-volatile EEPROM configuration removes the need for boot PROMs. The 117.6 MHz fMAX supports high-speed peripheral interfacing while the 5 V TTL I/O directly drives 74LS/74F-series logic without level shifters, simplifying PCB routing and BOM. This application is well-served by the device's deterministic timing, which guarantees that decode outputs are stable within one bus cycle regardless of how many address lines are combined in the AND-OR array.

🏭

Industrial Control Glue Logic

Factory automation controllers, PLCs, and CNC machines benefit from the EPM9400RC240-15's ability to consolidate dozens of 74-series logic chips into a single programmable device. The 400 macrocells handle complex state machines, encoder/decoder logic, and interrupt prioritization, while the JTAG ISP interface supports field firmware updates without dismantling control cabinets. With 5 V tolerance matching legacy optocoupler and relay driver interfaces common to PLC backplanes, the device operates reliably in noisy industrial environments when paired with proper bypass capacitors and PCB guard traces.

Telecom Backplane Interface Logic

Telecom T1/E1, ISDN, and legacy PBX backplanes rely on the EPM9400RC240-15 to implement HDLC framing, channel-associated signaling, and time-slot interchange. The device's 117.6 MHz fMAX comfortably exceeds 8.192 MHz E1 clock rates and 1.544 MHz T1 rates, providing ample timing margin for retiming and elastic-store operations. The 240-pin RQFP exposes enough user I/O for parallel backplane data buses (16-32 bits plus framing overhead) and its deterministic 15 ns delay simplifies timing closure on multi-drop bus designs. The non-volatile EEPROM configuration is particularly valuable in central-office equipment where unpredictable boot delays are unacceptable.

Legacy I/O Expansion and Peripheral Interface

Designing parallel-port expansion cards, SCSI terminator logic, or IDE/ATA interface bridges for legacy x86 motherboards is a classic application for the EPM9400RC240-15. Its 240-pin RQFP package provides enough user I/O to map full 16-bit ISA bus interfaces plus eight peripheral chip-select lines, while its 15 ns timing satisfies 8 MHz ISA bus cycles. The 5 V tolerance matches the TTL logic levels of vintage peripherals without external buffers, and the JTAG ISP enables in-system firmware iteration during prototype debugging - a major productivity advantage over masked ROM or PAL-based solutions.

Test and Measurement Instrumentation

Bench-top instruments such as logic analyzers, protocol analyzers, and signal generators use the EPM9400RC240-15 to implement timing generators, trigger sequencers, and pattern-match logic. The device's deterministic 15 ns timing enables precise trigger alignment within sampling windows, and its 400 macrocells can hold multi-stage trigger state machines spanning thousands of pattern states. The JTAG boundary-scan capability simplifies board-level test integration with other JTAG devices in the instrument, allowing single TAP-chain access during manufacturing test. The 5 V I/O is well matched to legacy GPIB/IEEE-488 interfaces still common in lab equipment.

🚗

Automotive Aftermarket and Hobbyist Retro Computing

The EPM9400RC240-15 remains popular in automotive aftermarket ECU modifications, retro-computing projects (such as Amiga or vintage-PC accelerators), and educational FPGA/CPLD trainers where 5 V tolerance is required. The non-volatile EEPROM configuration means designs boot instantly without bitstream loading - ideal for retro hardware where modern boot ROMs are unavailable. The 240-pin RQFP is easy to hand-solder with a hot-air station or inexpensively socketed for rapid iteration, and the mature MAX+PLUS II / Quartus design flow has extensive legacy design examples and reference designs freely available online.

What is the pin-to-pin propagation delay of the EPM9400RC240-15?

The EPM9400RC240-15 has a maximum pin-to-pin propagation delay (tPD) of 15 ns, indicating its mid-range speed grade within the MAX 9400 family. According to the MAX 9000 datasheet, the device's multiple-array-matrix architecture delivers deterministic timing independent of logic placement, so any registered or combinatorial path from any input pin to any output pin completes within 15 ns under worst-case commercial conditions.

How many macrocells and gates does the EPM9400RC240-15 have?

The EPM9400RC240-15 provides 400 macrocells with approximately 8,000 usable gates, placing it in the upper-mid density tier of the MAX 9000 family. Each macrocell contains a programmable register, product-term array, and I/O control block; 400 macrocells are sufficient for bus decoders, address mapping, peripheral glue logic, and complex state machines typical of 5 V industrial systems.

Does the EPM9400RC240-15 support in-system programming via JTAG?

Yes, the EPM9400RC240-15 supports 5.0 V in-system programmability through a built-in IEEE Std. 1149.1 JTAG interface, per the MAX 9000 datasheet. This allows board-level configuration, reconfiguration, and boundary-scan testing without removing the part from the PCB, provided the TMS, TCK, TDI, and TDO pins are correctly routed to the JTAG header or chain master.

What is the difference between EPM9400RC240-15 and EPM9400RC240-20?

The EPM9400RC240-15 and EPM9400RC240-20 share the same 240-pin RQFP package, 400 macrocells, and 5 V supply; the only difference is the speed grade -15 indicates 15 ns pin-to-pin delay while -20 indicates 20 ns. They are drop-in compatible: you can substitute the -20 with the -15 for higher fMAX (117.6 MHz vs ~83 MHz), or substitute the -15 with the -20 if a slightly slower timing is acceptable.

Where can I buy the EPM9400RC240-15 and what is the current price?

As of 2026-09-13, the EPM9400RC240-15 is in stock at multiple authorized distributors including DigiKey (4162039-ND), QTreeic (2,271 pcs), AIChipLink, Nantian, Jotrin, and Lovechip, with single-unit pricing around $38.50 and volume pricing dropping below $23 at 500 pieces. The Intel/Altera MAX 9000 family is in NRD (Not Recommended for New Design) status, so distributors continue to fulfill existing demand but allocation may tighten over time.

What is the lead time for EPM9400RC240-15 orders?

As of 2026-09-13, the EPM9400RC240-15 typically ships from US and Asian distributors with 1-3 week lead time for moderate quantities. Because the part is NRD (Not Recommended for New Design), inventory is finite and lead time may extend for larger orders; quote-on-request for 1,000+ pieces is recommended through distributors such as QTreeic, Lovechip, or Nantian.

Is the EPM9400RC240-15 a drop-in replacement for EPM9400RC208-15?

No - the EPM9400RC240-15 uses a 240-pin RQFP package while the EPM9400RC208-15 uses a 208-pin RQFP package, so the two parts are not pin-to-pin drop-in compatible despite sharing the same family and speed grade. Migration requires a PCB redesign and pin remapping; if the design supports either pin count, the 240-pin version offers more user I/O while the 208-pin version offers a smaller PCB footprint.

EPM9400RC240-15 vs EPM9320RI208-20 - which is better for 5 V glue logic?

The EPM9400RC240-15 has more macrocells (400 vs 320) and more user I/O via its 240-pin RQFP package compared to the EPM9320RI208-20's 208-pin package, but the EPM9320 is faster (20 ns vs 15 ns is not a fair comparison - check each speed grade). For high-density 5 V glue logic the EPM9400 wins; for compact designs the EPM9320 in the 208-pin footprint is preferable.

When should I choose the EPM9400RC240-15 over an FPGA?

Choose the EPM9400RC240-15 over an FPGA when you need deterministic 15 ns pin-to-pin timing regardless of logic placement, instant-on non-volatile configuration without external boot flash, 5 V I/O tolerance for legacy TTL buses, and a low unit cost under $40 for glue-logic functions. FPGAs are better when you need more than ~8,000 gates, hard IP cores (DSP, transceivers, memory controllers), or sub-10 ns logic delays.

What is the best drop-in replacement for the EPM9400RC240-15?

The best drop-in replacement for the EPM9400RC240-15 is the EPM9400RC240-20 from the same MAX 9400 family, sharing the 240-pin RQFP package, 400 macrocells, and 5 V supply but with a slower 20 ns speed grade - the only meaningful change is fMAX. For tighter performance, the -10 speed grade (EPM9400RC240-10) is also drop-in pin compatible within the same family, though availability may be limited.

Is the EPM9400RC240-15 the same as the EPM9400LC84-15?

No - the EPM9400RC240-15 (240-pin RQFP, 5 V) is not the same as the EPM9400LC84-15 (84-pin PLCC, 5 V). Both belong to the MAX 9400 family with 400 macrocells and 15 ns speed grade, but the packages differ significantly: 240 pins vs 84 pins means very different I/O counts, footprints, and pinouts. Choose RC240 for high-I/O applications, LC84 for compact designs.

Where do I download the EPM9400RC240-15 datasheet PDF?

The official EPM9400RC240-15 datasheet (MAX 9000 Device Family Data Sheet) is available as a PDF from the Altera/Intel literature archive at https://www.altera.com/literature/ds/m9000.pdf - this single datasheet covers the entire MAX 9000 family including the MAX 9400 series. The datasheet includes macrocell architecture, JTAG programming waveforms, electrical characteristics, and 240-RQFP pinout information.

Where can I find the EPM9400RC240-15 pinout diagram?

The EPM9400RC240-15 pinout is documented in the MAX 9000 Device Family Data Sheet (DS-M9000) section covering 240-pin RQFP packages. The pinout assigns dedicated JTAG pins (TMS, TCK, TDI, TDO), dedicated input pins, dedicated I/O pins, and power/ground pins; user I/O pins are arranged in banks around the package periphery following Altera's standard RQFP pin numbering convention.

What are the key specifications of the EPM9400RC240-15 that engineers should know?

The EPM9400RC240-15 is a 400-macrocell CPLD in the MAX 9400 family with 8,000 usable gates, 15 ns pin-to-pin delay (fMAX approximately 117.6 MHz), 5.0 V single supply, IEEE 1149.1 JTAG ISP, and a 240-pin RQFP package. It belongs to the broader category of non-volatile programmable logic, offers deterministic timing independent of logic placement, and is NRD (Not Recommended for New Design) per Intel lifecycle policy as of 2026-09-13.

選型指南

Choose the EPM9400RC240-15 when you need 400 macrocells of non-volatile, deterministic 15 ns glue logic with maximum I/O count in a 240-RQFP package - ideal for 5 V industrial bus decoding, telecom backplane interfacing, and large-scale state-machine replacement. Choose the EPM9400RC240-20 if a slower 20 ns timing is acceptable (typically 15-20% cost savings); choose the EPM9400RC240-10 if you need faster 10 ns timing. Choose a smaller MAX 9000 device (EPM9320, EPM9400LC84-15) when PCB area is constrained and fewer I/O pins suffice. For new designs in 3.3 V systems, consider migrating to MAX II or MAX V CPLDs which offer lower power at 3.3 V; for high-density logic, migrate to Cyclone FPGAs.

設計說明

Estimated: with 5.0 V supply and worst-case I/O toggling at 117 MHz across all 240 I/O pins, typical ICC for the EPM9400RC240-15 is approximately 200-300 mA. Place a 0.1 uF ceramic decoupling capacitor within 5 mm of every VCC/GND pin pair (24 VCC and 24 GND pins total on 240-RQFP), and add a single 10 uF bulk tantalum or ceramic cap on each side of the package to suppress voltage transients during simultaneous switching output (SSO) events.

The 240-RQFP package uses 0.5 mm pitch gull-wing leads with a 32x32 mm body - allocate at least 35x35 mm PCB area and use 4-layer stack-up with continuous ground plane beneath the device to control impedance and reduce SSO ground bounce. Route JTAG signals (TMS, TCK, TDI, TDO) away from high-speed I/O to avoid coupling, and keep TCK trace length under 100 mm to meet IEEE 1149.1 timing requirements.

Do not assume the EPM9400RC240-15 is 3.3 V tolerant - the MAX 9000 family requires 5.0 V VCC and 5.0 V I/O levels. Driving inputs above 5.5 V or below -0.5 V will damage the device. When mixing with 3.3 V logic, use external level shifters such as 74LVC4245A or 74HCT245. Also note that the 240-RQFP requires careful reflow profile: peak temperature 245C for no more than 30 seconds to prevent RQFP package delamination.
