MPN: EPM9320ALC84-15 ✗ Cuối đờiEPM9320ALC84-15 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that combines multiple PAL-like macrocell blocks with a central interconnect matrix. The MAX 9000 family sits between classic 22V10-style SPLDs and larger FPGAs, targeting designs that need deterministic timing, ISP (in-system programmability) via JTAG, and 100% route-ability at densities up to ~560 macrocells. Compared with an FPGA, a CPLD such as the EPM9320ALC84-15 has lower absolute logic capacity but offers predictable pin-to-pin delays, no external boot PROM, and very low standby current.
Key specifications include 320 macrocells, 6 K usable gates, a tPD of 16 ns, a 5 V ±5% (4.75 V to 5.25 V) supply, 56 user I/O lines, and 84 PLCC J-leads. The device supports IEEE Std 1149.1 JTAG boundary-scan, in-system programming via the JTAG port, and a power-down feature that minimizes standby consumption. The 84-pin PLCC package is through-hole-friendly and easy to hand-prototype, which is one of the reasons this part remains specified in long-lifecycle industrial controllers.
Architecturally, the EPM9320ALC84-15 uses Altera's classic MAX architecture with EEPROM-based configuration cells, a programmable AND array feeding a fixed OR array, and per-macrocell flip-flops with programmable polarity. The interconnect is a continuous, fast-path switch matrix that delivers uniform 16 ns delays across all pins regardless of placement, which is the principal reason designers choose this family over look-alike FPGAs for control-plane logic.
Typical applications include 5 V industrial PLC glue logic, ISA/PCI bus address decoding, motor-control state machines, telecom backplane control, and legacy ASIC replacement in medical and aerospace systems. Designers should also evaluate the EPM9320ALC84-10 (10 ns tPD) when margin is tight, or migrate to MAX II or MAX V CPLDs if lower power is required.
When designing with the EPM9320ALC84-15, pay particular attention to the global clock and clear pin assignments and ensure that the JTAG chain is correctly ordered in multi-device boards. The device requires a single 5 V supply and supports ISP via JTAG; an external configuration PROM is not required.

Ứng dụng tiêu biểu
EPM9320ALC84-15 phù hợp cho 6 Áp dụngs: 5 V Industrial PLC Glue Logic, ISA/PCI Bus Address Decoding & Chip-Select Generation, Motor Control State Machines, Telecom Backplane Control Logic, Legacy ASIC Replacement, Embedded System Glue Logic.
5 V Industrial PLC Glue Logic
The EPM9320ALC84-15 is well-suited to 5 V industrial PLC glue-logic integration: its 320 macrocells and 56 I/O easily absorb address decoding, peripheral chip-select generation, and timer/counter fan-out for legacy PLC backplanes. With a 16 ns worst-case tPD, the part deterministically meets timing of 25 MHz state machines commonly used in PLC scan loops. The 84-pin PLCC socket-mount format supports field-replacement and long-lifecycle industrial maintenance, while JTAG ISP allows firmware updates without removing the board. Compared with stitching multiple 22V10 SPLDs, this CPLD reduces board area and improves noise margin by replacing discrete glue logic with a single 5 V device.

ISA/PCI Bus Address Decoding & Chip-Select Generation
In ISA or PCI bus address decoding, the EPM9320ALC84-15's 56 I/O and 16 LABs provide enough macrocells to decode the full 24-bit address bus and generate 8 to 12 peripheral chip-selects in a single device. Its 16 ns tPD adds minimal latency to bus cycles, and the deterministic interconnect guarantees that any chip-select arrives within the same window regardless of which macrocell synthesizes it. Designers typically pair this part with 5 V-tolerant bus transceivers and use the JTAG port for ISP of updated decode maps. The PLCC-84 socket also makes this a common insertion point for legacy PC/104 and VMEbus controllers where the bus architecture predates modern PLD/FPGA tooling.

Motor Control State Machines
For stepper and BLDC motor control, the EPM9320ALC84-15 synthesizes the commutation state machine, PWM blanking logic, and fault handlers in a single 5 V device. With 16 LABs and 320 macrocells, the design can encode full sinusoidal commutation tables and quadrature decoders without external logic; the 16 ns tPD keeps the loop tight enough for 50 kHz PWM rates. The PLCC-84 package is preferred in motor drives for its thermal headroom at high ambient temperatures. JTAG ISP enables field updates of control firmware, while the deterministic timing ensures uniform PWM edge placement across all channels - critical for low-noise motor operation.
Được đề xuất
Telecom Backplane Control Logic
The EPM9320ALC84-15 integrates backplane control logic in T1/E1 and legacy SDH/SONET systems where 5 V tolerance and deterministic timing are required. Its 56 I/O can absorb clock-distribution trees, alarm-input scanning, and LED-status drivers that would otherwise require multiple PALs. The 16 ns tPD is comfortably fast for backplane housekeeping buses operating below 30 MHz, while the PLCC-84 package withstands the conformal coating and extended temperature of telecom cabinets. JTAG boundary-scan enables in-service board test, an important feature for the long service life of central-office equipment.

Legacy ASIC Replacement
The EPM9320ALC84-15 is a classic ASIC replacement for end-of-life gate arrays in long-lifecycle medical, aerospace, and industrial-control products. With 320 macrocells and 6 K usable gates, it absorbs medium-complexity ASICs from the 1990s, and the JTAG ISP interface allows last-minute design changes without re-spinning masks. The 84-PLCC socket simplifies field service and qualification - legacy ASICs in non-standard packages are notoriously hard to second-source. Designers keep the 16 ns tPD margin for legacy timing budgets while benefiting from a programmable, software-defined implementation that reduces NRE.
Được đề xuất
Embedded System Glue Logic
In embedded designs built around legacy x86, 68k, or PowerPC processors, the EPM9320ALC84-15 consolidates chip-select, wait-state, and interrupt-priority logic in a single 5 V device. The 56 user I/O handle eight to twelve peripheral selects plus interrupt controllers, and the 16 LABs accommodate address-decoding tables up to 16-bit wide. The deterministic 16 ns tPD ensures that processor-side accesses to slow peripherals remain within the bus-cycle budget. The PLCC-84 package is widely supported on embedded SBCs (PC/104, VME), and JTAG ISP allows remote firmware updates via boundary-scan tools in production.

Ghi chú thiết kế
The EPM9320ALC84-15 requires a single 4.75 V to 5.25 V supply with adequate decoupling. Place 0.1 uF ceramic bypass capacitors within 5 mm of each VCC pin (the 84-PLCC exposes VCC on pins 7, 15, 33, 53, 81). A bulk 10 uF tantalum or ceramic cap on the supply rail handles transient switching current during simultaneous I/O toggling. Estimated: at 56 I/O switching at 10 MHz, peak supply current can reach ~150 mA; budget for 300 mA worst case in the regulator. Connect all five GND pins (21, 41, 57, 68) directly to a low-impedance ground plane.
When laying out the 84-pin PLCC socket, fan out the inner ring of pins on the top layer with vias to an inner power/ground split plane. The MAX 9000's deterministic interconnect requires no special signal-integrity routing, but keep JTAG traces (TDI/TDO/TMS/TCK) short and isolated from switching outputs. Estimated: a 4-layer PCB with 1 oz copper and a 0.5 oz inner ground plane comfortably meets the 16 ns timing budget; for 10 ns drop-in operation use 2 oz copper on signal layers. Avoid 90-degree bends on clock pins GCLK1/GCLK2 to preserve duty cycle.
Do not confuse speed grade '15' (16 ns) with '10' (10 ns) or '12' (12 ns) - all three grades share the same 84-PLCC pinout and JTAG, but the tPD differs by up to 60%. For designs migrating from the MAX 7000 family, note that the MAX 9000 uses different programming files; re-compile in MAX+PLUS II or Quartus before loading the JTAG image. Estimated: typical I_OL/I_OH drive is 8 mA per pin in 5 V mode, sufficient for LED drive but inadequate for bus termination - place external buffers for backplane signals. Also note that the 'LC' suffix denotes commercial temperature, not 'lead-free'.
