EPM7096LC68-15 - MAX 7000 CPLD, 96 Macrocells, 15ns | Altera
MPN: EPM7096LC68-15 ✗ Cuối đờiEPM7096LC68-15 Tóm tắt
What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that sits between simple SPLDs and large FPGAs in the programmable logic hierarchy. It contains multiple logic array blocks (LABs) interconnected by a programmable switch matrix, retaining its configuration in on-chip EEPROM without needing a separate boot memory. CPLDs are widely used for glue logic, bus interfacing, address decoding, state machines, and power-up control because of their deterministic timing, instant-on behavior, and robust non-volatile storage.
Key features of the EPM7096LC68-15 include 96 macrocells, 4 logic array blocks (LABs), and 52 user I/O pins for flexible signal routing. The device operates from a 4.75 V to 5.25 V supply, supports the standard 5V TTL interface levels, and offers a 15 ns maximum propagation delay that suits moderate-speed control logic. Its high-performance EEPROM technology delivers 100 erase/program cycles per macrocell and supports in-system programming through JTAG or via Altera's ByteBlaster/ByteBlasterMV download cables.
The MAX 7000 architecture separates combinational and registered logic, with each macrocell containing a programmable AND/OR array and a configurable flip-flop. This design gives predictable timing paths and makes the EPM7096LC68-15 particularly attractive for asynchronous and registered state-machine designs. The device is also highly tolerant of 5V mixed-signal environments, which is why it remains common in legacy industrial, telecommunications, and test equipment designs.
Typical applications include bus interfacing and protocol bridging, address decoding for microprocessors, state-machine controllers, glue logic replacement for discrete 74-series TTL, and I/O expansion. Designers also use the EPM7096LC68-15 for power-up sequencing logic because its non-volatile EEPROM boots in a deterministic state without an external configuration device.
When designing with this CPLD, account for the 5V supply requirement and provide proper decoupling on every VCC pin. The PLCC-68 package is socket-compatible with several EPM7128 variants, allowing a path to higher macrocell density without reworking the PCB footprint.

Ứng dụng tiêu biểu
EPM7096LC68-15 phù hợp cho 6 Áp dụngs: Microprocessor Address Decoding, Bus Interface and Protocol Bridging, State Machine Controllers, TTL Glue Logic Replacement, Power-Up Sequencing Logic, Legacy Industrial Control and Test Equipment.
Microprocessor Address Decoding
The EPM7096LC68-15 fits address-decoding tasks because 96 macrocells easily map a full 24-bit address decode tree plus chip-select glue logic, and its 15 ns tPD is faster than most 5V microprocessors of its era. Placed between the processor and peripheral bus, it replaces a bank of 74LS138 / 74LS139 decoders with one PLCC-68 device. Its non-volatile EEPROM boots in a deterministic state, so chip selects are valid on the very first clock cycle without waiting for FPGA configuration. The 5V TTL-compatible I/O simplifies interface to legacy 8086, 68k, and 8051-style buses without level shifters.

Bus Interface and Protocol Bridging
The EPM7096LC68-15 is widely used as a glue-logic bridge between mismatched bus standards (ISA, PCI, VME, parallel data ports) because 96 macrocells handle full 16-bit or 32-bit state machines and 52 I/O pins expose enough user signals for multi-bus fan-out. Its 15 ns propagation delay comfortably meets ISA and VME bus timing budgets. In-system JTAG programming lets field engineers re-flash the bridge logic without removing the card from the chassis. The 5V-tolerant I/O matches legacy peripheral ASICs without external buffers.
Được đề xuất
State Machine Controllers
With 96 macrocells and deterministic 15 ns timing, the EPM7096LC68-15 implements multi-state Mealy and Moore controllers for industrial sequencing, vending machines, and instrument front panels. Each macrocell's flip-flop plus the AND/OR array maps cleanly onto standard one-hot or binary-encoded state diagrams. The deterministic tPD makes worst-case timing analyzable without statistical static timing analysis tooling. The non-volatile EEPROM boots to a known state on every power-up, which is critical for safety interlocks.
Được đề xuất
TTL Glue Logic Replacement
Engineers replace banks of 74LS/74HC glue logic with a single EPM7096LC68-15 to consolidate scattered gates, reduce PCB area, and improve design revision flexibility. Up to 96 macrocells can absorb the equivalent of 30 to 50 SSI/MSI packages, with 52 user I/O pins exposed for signal fan-in and fan-out. JTAG programming lets engineers iterate the logic without board rework. The 5V supply directly replaces TTL rails without level translation.
Được đề xuất
Power-Up Sequencing Logic
The EPM7096LC68-15 is a natural fit for power-up and power-down sequencing in multi-rail systems because its non-volatile EEPROM guarantees a deterministic output state from the very first clock cycle. Engineers encode the rail-enable order, fault detection, and reset pulse generation inside one PLCC-68 device. The 5V supply rails match typical housekeeping regulators in telecom and industrial chassis. The 15 ns delay is faster than any external power-good comparator it would replace.
Được đề xuất
Legacy Industrial Control and Test Equipment
Industrial controllers, programmable logic controllers (PLCs), and ATE test equipment from the 1990s and 2000s used the EPM7096LC68-15 because of its 5V tolerance, 96-macrocell capacity, and PLCC-68 socket-friendly package. The device reliably implements encoder counters, quadrature decoders, and timing-pulse generators at 15 ns. Field-replaceable PLCC sockets make board swaps painless in 24/7 production environments. Replacement boards are still designed around this CPLD to avoid revalidating regulatory certifications.

Ghi chú thiết kế
The EPM7096LC68-15 operates from a single 5.0 V (4.75 V to 5.25 V) supply. Estimated: with 52 I/Os toggling at moderate CMOS loading, the device draws roughly 50 to 150 mA dynamic plus EEPROM programming current during ISP. Decouple every VCC pin (1, 21, 41, 61 in PLCC-68) with a 0.1 uF ceramic cap placed within 5 mm of the pin, and add a single 10 uF bulk tantalum or ceramic capacitor near the package. JTAG ISP pulses can briefly raise Icc, so adequate bulk capacitance prevents the rail from sagging during programming.
The PLCC-68 footprint supports both surface-mount soldering and a through-hole PLCC socket, which is convenient for legacy industrial boards. Place the JTAG header (TCK, TMS, TDI, TDO plus optional TRST) within 100 mm of the device and route TDI/TDO with series 100 ohm termination to dampen ringing. Keep TCK and TMS away from clock edges on adjacent I/O banks; route them on an inner layer with ground reference to limit crosstalk.
Do not assume the EPM7096LC68-15 is 3.3V tolerant - all I/O banks operate at 5V TTL levels and exceeding 5.25 V will damage the EEPROM cells. Do not program the part with a 3.3V-only JTAG programmer; use Altera ByteBlasterMV or a 5V-tolerant download cable. When migrating a design from EPM7096LC68-15 to EPM7128SLC68-15 in the same socket, recompile the project in MAX+PLUS II or Quartus to regenerate the JEDEC file; the macrocell counts differ and the bitstream is not interchangeable.
Each macrocell output has a programmable slew rate (slow/fast); for switching frequencies above 33 MHz or for heavily loaded buses, select the slow slew-rate option to reduce ground bounce. Place 22 ohm to 33 ohm series resistors on high-edge-rate outputs driving long PCB traces or backplane connectors. The MAX 7000 internal interconnect is non-multiplexed and deterministic, so static timing analysis in Quartus yields the exact worst-case tCO and tSU values without statistical margins.
