EPM5192JI - 192 Macrocell MAX 5000 EPLD | Altera | 84-Pin PLCC
MPN： EPM5192JI ✗ 停產EPM5192JI 概覽
A UV-erasable CMOS EPLD is a type of Erasable Programmable Logic Device built on a non-volatile EPROM cell technology that can be erased by exposing the package window to ultraviolet light. EPLDs sit in the broader hierarchy: programmable logic > PLD > EPLD > CMOS EPLD, and the MAX 5000 family was Altera's high-density generation of the early-to-mid 1990s, positioned between simple PALs and the later, more capable MAX 7000/MAX 9000 families. The EPM5192JI is intended for glue-logic integration, decoder/encoder consolidation, and state-machine replacement in industrial and telecom equipment.
Key features include 192 macrocells, 12 LABs, 64 bidirectional I/O pins, 7 dedicated inputs, 55ns pin-to-pin propagation delay (tpd), and 100% PCI-compliant bus interfaces for 5V systems. The architecture uses a programmable AND/OR array feeding each macrocell, with per-macrocell flip-flops, individually-programmable I/O architecture, and JTAG-less in-system programmability through the older MAX 5000 programming algorithm. The device is fabricated in a 5V CMOS EPROM process that requires a windowed ceramic package (the JI suffix indicates a windowed PLCC) for erasure.
Typical applications include 5V PCI bus interfaces, glue-logic consolidation, custom state machines, address decoding for microprocessor systems, and bus-width adaptation in industrial controllers. The wide fan-in and shared LAB expander pools give predictable timing suitable for synchronous control logic. When designing with the EPM5192JI, leave adequate clearance around the package window for UV erasure (windowed parts only) and respect the 4.75V-5.25V supply tolerance specified in the Altera datasheet to avoid programming-margin issues during ISP.

典型應用
EPM5192JI 適用於 6 應用s: 5V PCI Bus Glue Logic, Microprocessor Address Decoder, Custom State Machine Controller, Industrial Controller I/O Expansion, Telecom Line Card Interface, Legacy VME/VXI Card Integration.
5V PCI Bus Glue Logic
The EPM5192JI consolidates PCI bus arbitration, interrupt steering, and address decoding into a single 192-macrocell device, replacing 4-6 discrete 22V10 PALs on a typical motherboard or add-in card. Its 64 user I/O pins comfortably handle 32-bit PCI address/data plus sideband signals, and the 5V TTL-compatible I/Os are fully PCI 5V compliant per the MAX 5000 datasheet. Designers should budget 4.75-5.25V supply tolerance and add bulk decoupling at the PLCC socket for noise-free operation. Companion: 74FCT245 bus transceivers, 74FCT574 latches for registered outputs.
推薦
Microprocessor Address Decoder
In 80x86, 68k, and PowerPC embedded systems, the EPM5192JI decodes full 24- or 32-bit address buses into chip-select and interrupt acknowledge outputs, replacing cascaded 16L8/20L8 GALs with one part. The 12 LABs deliver abundant product-term capacity for complex memory maps with multiple wait-state and bank-switching zones. With 7 dedicated inputs the device accommodates address plus qualifier signals without consuming user I/O. Companion: 74FCT138 for undecoded peripherals, 74HC573 for address latching.
推薦
Custom State Machine Controller
Engineers use the EPM5192JI to implement complex finite state machines with 32-64 states, multiplexed datapath control, and encoded output waveforms - replacing thousands of gates of TTL or dozens of PALs. Each of the 192 macrocells hosts a flip-flop with separate clock, reset, and preset, giving designers granular state-encoding freedom. The predictable 55ns pin-to-pin delay supports sampling rates up to ~18 MHz in synchronous designs. Companion: 74HC245 bus drivers, 74FCT74 dual D flip-flops for skew matching.
推薦
Industrial Controller I/O Expansion
In PLC-style industrial controllers, the EPM5192JI multiplexes sensor inputs, drives relay and SSR control outputs, and implements safety-interlock logic on a single 5V part. Its 64 I/O pins handle 32-input/32-output modules easily, and the industrial -40 to +125C operating range (I-suffix) is rated for cabinet and chassis environments. UV erasure allows last-minute firmware changes during factory commissioning. Companion: TLP281 optocouplers for isolation, ULN2003 driver arrays.
推薦
Telecom Line Card Interface
Telecom line cards of the late 1990s and early 2000s used the EPM5192JI for T1/E1 framer glue logic, timeslot assignment, and HDLC channel routing, leveraging its high I/O count and 5V PCI-compliant interface to upstream ASICs. The 12 LABs efficiently implement per-channel state machines for signaling and alarming. Industrial temperature grade supports controlled-environment central offices. Companion: DS2155 T1/E1 framer, DS21372 LIU, 5V LDO regulators.
推薦
Legacy VME/VXI Card Integration
VMEbus and VXI instrumentation cards integrated in the 1990s use the EPM5192JI for bus arbitration, interrupt acknowledge, and address decode across the 32-bit VMEbus. The part's 64 I/O pins absorb the full D-size VME connector plus local bus transceivers, and the 5V TTL interface matches the VMEbus electrical spec natively. Windowed packages allow last-time-buy firmware updates. Companion: DS96F174C RS-485 drivers, 74FCT16245 transceivers, 5V supervisory reset ICs.

設計說明
Estimated: At 5V VCC, 64 I/O pins each toggling at 1 MHz with 50 pF load, the EPM5192JI draws approximately 80 mA from logic plus I/O switching, dissipating roughly 0.4 W. In a windowed ceramic 84-pin PLCC with theta_JA near 50 C/W, junction temperature rises only 20 C above ambient, so no heatsink is required. Verify by measuring VCC current on the prototype; if it exceeds 150 mA, reduce clock frequency or I/O count to stay within the commercial/industrial junction limit of 150 C.
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of each VCC pin (4-6 pins on the 84-pin PLCC) and a 10 uF tantalum bulk capacitor at the socket supply entry. Keep the PLCC socket footprint compatible with both windowed (J-suffix) and plastic (C-suffix) packages so that engineering prototypes can use windowed parts for UV erasure, while production units use cheaper plastic one-time-programmable parts. Maintain a 3 mm clearance around the package window for the UV eraser lamp.
Do not assume the EPM5192JI's I/O pins are 3.3 V tolerant - the MAX 5000 family uses 5 V TTL inputs with VIH min at 2.0 V and VIL max at 0.8 V. Mixing 3.3 V logic directly will violate VIL and cause intermittent failures. Use a 74LVC245 or 74HCT245 level shifter between 3.3 V devices and the EPM5192JI inputs. Also, respect the 4.75-5.25 V supply tolerance specified in the datasheet; operation below 4.75 V reduces noise margin and may cause programming-margin failures during in-system programming.
At output toggle rates above 10 MHz, the 84-pin PLCC lead inductance (~5 nH per pin) and 50 pF PCB trace capacitance form LC resonances near 100 MHz that can ring above VCC or below GND. Add 22-33 ohm series damping resistors on clock and high-speed outputs, and keep traces shorter than 50 mm. For multi-card systems, source-terminate clock lines at the driver end with 33 ohm to match the PLCC output impedance.
合規資訊
EPM5192JI predates RoHS effective dates and uses tin-lead solder terminations in a ceramic PLCC, so RoHS 2 (2011) compliance is not applicable. Reach, halogen, and conflict-minerals status not published by Altera for this legacy part.
