EPM9320ALC84-10N Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits hierarchically between simple PAL/GAL splds and high-density FPGAs. It provides predictable timing, instant-on operation, and high fan-in macrocell structures, making it ideal for deterministic control logic. CPLDs are typically used for address decoding, peripheral interfacing, bus bridging, and power-sequencing controllers where fixed, low-latency response is required. The MAX 9000 family extends classic EPLD architecture to higher logic densities while retaining the deterministic timing that made the MAX 5000 and MAX 7000 families popular in telecom, industrial, and embedded designs.
Key features of the EPM9320ALC84-10N include 320 macrocells distributed across 16 logic array blocks (LABs), 60 user I/O pins, 5 V core operation (5.0 V nominal VCC), in-system programmability via JTAG (IEEE 1149.1), and a commercial 0C to 70C operating temperature range. The device includes per-macrocell registers, programmable interconnect array (PIA), and dedicated input/output control blocks. The 84-pin PLCC package provides through-hole compatibility for legacy industrial backplanes, retrofit designs, and existing production assemblies where socket replacement is preferable to redesign.
From an architectural standpoint, the EPM9320A uses Altera's classic MAX architecture with EEPROM-based configuration cells, meaning the device retains its programmed logic without external boot memory. Configuration is loaded via JTAG using a ByteBlaster or compatible programmer, and the part can be reprogrammed thousands of times. The 10 ns tPD and 144.9 MHz fCNT make this part suitable for state machines running at moderate clock rates and for pipelined control logic.
Typical applications include legacy industrial control boards, telecom line-card glue logic, address-decoding and chip-select generation, peripheral bus interfacing (ISA, PCI, VME), motor-control state machines, and retrofit/repair scenarios where the original MAX 9000 part must be replaced. The part is also widely used in educational boards, prototype development, and military/aerospace systems where the MAX 9000 family has long design-cycle approval.
When designing with the EPM9320ALC84-10N, observe the recommended 5.0 V VCC tolerance (the A-suffix denotes 5 V operation, not the 3.3 V-compatible LC/RC/QI variants). Decouple each VCC/ground pair with a 0.1 F ceramic capacitor placed within 50 mils of the package pin, and adhere to the JTAG chain layout guidelines for multi-device boundary-scan configurations. The 84-PLCC socket should be a low-profile machine-pin or open-frame type rated for the operating temperature range.

Applications typiques
EPM9320ALC84-10N convient pour 6 applications: Legacy Industrial Control Boards, Telecom Line-Card Glue Logic, Address Decoding and Chip-Select Generation, Peripheral Bus Interfacing (ISA / PCI / VME), Motor-Control State Machines, Retrofit and Repair of Legacy Equipment.
Legacy Industrial Control Boards
The EPM9320ALC84-10N is widely deployed in legacy industrial control boards where its 320 macrocells and 60 I/O pins provide ample capacity for PLC-style glue logic, sensor multiplexing, and actuator control sequencing. With a deterministic 10 ns tPD and 5 V I/O tolerance, it directly interfaces to 5 V TTL/CMOS peripherals, encoder inputs, and opto-isolated feedback lines without level shifters. The 84-PLCC socketed package allows field-replacement on existing backplanes, minimizing downtime for retrofit programs in factory automation lines that have been in service for 15-20 years or longer.
Recommandé
Telecom Line-Card Glue Logic
In telecom line-card and central-office equipment, the EPM9320ALC84-10N serves as deterministic glue logic between framer ICs, TDM switches, and backplane transceivers. Its 144.9 MHz fCNT supports 8 kHz/16 kHz/32 kHz time-slot framing alongside higher-speed E1/T1 clock recovery schemes, while the predictable PIA-based interconnect ensures zero-jitter output timing critical for PDH and SDH tributaries. The JTAG interface enables board-level boundary-scan testing during manufacture and field diagnostics, satisfying the IEEE 1149.1 testability mandates common in telecom-grade hardware. Obsolescence remains a key concern, so redesign programs target MAX II/MAX V equivalents.
Recommandé
Address Decoding and Chip-Select Generation
The EPM9320ALC84-10N is ideally suited for memory and peripheral address decoding on legacy microprocessor boards, generating chip-select signals for SRAM, ROM, and I/O peripherals from a wide address bus. With 10 ns tPD, it produces clean chip-select pulses well within one clock cycle of 25-50 MHz 80x86, 68k, or PowerPC host buses. The 320 macrocells comfortably handle 16-to-24-bit address decoding with multiple active-low and active-high outputs, and the in-system programmability lets engineers iterate decoder maps during prototype without re-spinning the PCB. This application is one of the most common uses for the MAX 9000 family.
Recommandé
Peripheral Bus Interfacing (ISA / PCI / VME)
The EPM9320ALC84-10N acts as a bus-interface bridge between legacy ISA, VME, and simple PCI target peripherals. It implements bus-state decoders, hand-shake sequencers, and interrupt controllers with deterministic 10 ns response, eliminating wait-state unpredictability from discrete TTL logic. The 5 V tolerant I/O connects directly to bus transceivers, while 60 user I/O pins handle address, data steering, and control signal multiplexing. The 84-PLCC socket allows engineers to swap parts for speed-grade upgrades or logic revisions during board bring-up without reworking the PCB.
Recommandé
Motor-Control State Machines
The EPM9320ALC84-10N implements multi-axis stepper and BLDC motor control state machines by sequencing PWM generators, decoding Hall-sensor or quadrature-encoder feedback, and arbitrating direction/inhibit signals. The 10 ns tPD enables sub-microsecond control-loop updates at 50-100 kHz PWM rates, and the 60 user I/O pins handle multiple axes (typically 3-4 steppers or 2 BLDC motors) from a single device. EEPROM-based configuration retains state machine tables across power cycles, and the JTAG interface supports in-circuit debugging via Altera MAX+PLUS II or Quartus signal-tap logic.
Recommandé
Retrofit and Repair of Legacy Equipment
The EPM9320ALC84-10N is primarily sourced today to repair and extend the service life of legacy equipment originally designed in the late 1990s and early 2000s. Medical imaging systems, military radios, industrial CNC controllers, and avionics subsystems all depend on the MAX 9000 family's reliability and 5 V tolerance. The PLCC socket mounting is critical here - it allows technicians to swap parts without specialized rework tools, even in field-deployed units. Authorized obsolete-part brokers maintain traceability documentation (date code, lot, original manufacturer) required by aerospace and medical OEM service contracts.

Notes de conception
The EPM9320ALC84-10N requires a stable 5.0 V VCC supply with a tolerance of +/-5% (4.75 V to 5.25 V). Place a 0.1 uF decoupling capacitor within 50 mils of each VCC pin (the 84-PLCC has multiple VCC and GND pins distributed around the package) to minimize ground bounce and VCC sag during simultaneous switching of high-fanout outputs. Bulk decoupling of 10-47 uF tantalum or aluminum polymer is recommended at the board-level power entry to the device's VCC rail.
The 84-PLCC package is a through-hole socket-mount part. Use a high-quality machined-pin PLCC socket (3M, Mill-Max, or equivalent) rated for the operating temperature range, especially for industrial and military designs. Avoid low-cost stamped sockets which may lose contact after thermal cycling. The PLCC socket footprint must accommodate the J-lead geometry - refer to the JEDEC MO-047 package outline for recommended land pattern dimensions.
Do not confuse the A-suffix (5 V VCC) EPM9320ALC84-10N with the L-suffix (3.3 V VCC) EPM9320LC84-15/20. Applying 5 V to a 3.3 V L-variant will permanently damage the device. The 'A' and 'L' letters in the Altera MAX 9000 nomenclature encode the voltage class, and engineers upgrading or downgrading designs must verify both the voltage and speed-grade suffixes. The 'N' suffix indicates tape-and-reel packaging versus tray.
Route JTAG signals (TMS, TCK, TDI, TDO) as short, parallel traces with a ground return path to avoid crosstalk. Place a 10 kohm pull-up on TCK and TMS to prevent floating inputs that may inadvertently trigger JTAG state-machine transitions. If the device is part of a multi-device JTAG chain, include 4.7 kohm series termination resistors on TDI/TDO between adjacent devices to dampen reflections on longer chains (>6 inches).
Informations de conformité
MAX 9000 family parts from this generation typically use tin-lead (SnPb) PLCC leads and are not RoHS-compliant. Lead-free variants carry the 'N' or other suffix. For new RoHS-compliant designs, modern MAX II/MAX V/MAX 10 CPLD families should be evaluated.
