EPM9400RC240-15 - 400-Macrocell MAX 9000 CPLD, 15ns, 240-RQFP | Intel
MPN: EPM9400RC240-15 ✗ Akhir HidupEPM9400RC240-15 Ringkasan
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.

Aplikasi Umum
EPM9400RC240-15 cocok untuk 6 aplikasis: 5V Bus Decoding and Address Mapping, Industrial Control Glue Logic, Telecom Backplane Interface Logic, Legacy I/O Expansion and Peripheral Interface, Test and Measurement Instrumentation, Automotive Aftermarket and Hobbyist Retro Computing.
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.

Catatan Desain
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.
Informasi Konformitas
Compliance status not explicitly stated in the provided data; EPM9400RC240-15N suffix variant is typically Pb-free per Altera/Intel legacy nomenclature, but confirm with distributor before Pb-free reflow assembly.
