MPN: EPM7160ELC84-20 ✗ Cuối đờiEPM7160ELC84-20 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that combines the architecture of multiple PAL/GAL-like PLDs on a single chip with a programmable interconnect matrix. CPLDs occupy the middle ground between small discrete logic ICs (gates, muxes, flip-flops) and larger FPGAs: they offer deterministic timing, sub-100 ns propagation delays, and zero configuration time at power-up. In the broader system hierarchy, the MAX 7000 CPLD sits between 74-series discrete logic and SRAM-based FPGAs, serving as the ideal integration point for board-level glue logic, address decoding, interrupt steering, and I/O expansion. The MAX 7000 series is a foundational product line that helped popularize ISP and JTAG-based programming in mainstream digital design.
Key features include 3,200 usable gates, 64 I/O pins with 5-V tolerant I/O on most variants, four global clock inputs, and a JTAG-compliant boundary-scan test interface. The device operates from a single 5.0 V supply (VCCINT and VCCIO combined) with low standby current, and supports commercial (0C to +70C) operating temperature ranges. Programming is performed via the JTAG port using the ByteBlaster or BitBlaster download cable, or in-system from a microcontroller-driven JTAG master, eliminating the need for a dedicated programmer.
Typical applications include peripheral glue logic in microprocessor and DSP systems, address decoding and chip-select generation, bus arbitration and interrupt prioritization, register-based I/O expansion, and JTAG-driven board-level test infrastructure. The 84-pin PLCC package is socket-friendly, supporting both production assembly and easy breadboard prototyping for engineering development.
When designing with this device, designers should provide adequate decoupling (typically 0.1 uF per VCC pin plus a 10 uF bulk capacitor) and follow Altera's JTAG chain recommendations when multiple devices share the same programming port. The PLCC-84 footprint is a JEDEC-standard land pattern, but designers migrating to lead-free assemblies should verify the soldering profile against the JEDEC J-STD-020 moisture sensitivity level (MSL) rating.

Ứng dụng tiêu biểu
EPM7160ELC84-20 phù hợp cho 7 Áp dụngs: Microprocessor Gl ue Logic and Chip-Select Decoding, Address Decoding and Memory Bank Selection, Bus Arbitration and Interrupt Steering, Register-Based I/O Expansion, JTAG-Driven Board-Level Test Infrastructure, State Machine and Protocol Conversion, Legacy Industrial Control Replacement.
Microprocessor Gl ue Logic and Chip-Select Decoding
The EPM7160ELC84-20 fits this application because its 160 macrocells and 64 user I/O pins provide ample capacity to integrate scattered 74-series glue logic into a single programmable device. With 20 ns pin-to-pin delay and 5.0-V tolerant I/O, the CPLD directly interfaces with 5-V microprocessors and peripherals without level shifters, while deterministic timing ensures chip-select signals are generated with predictable setup/hold margins. Compared to discrete logic ICs, the EPM7160ELC84-20 reduces board area, simplifies BOM, and allows late-stage design changes via JTAG re-programming. In a typical design it replaces dozens of AND/OR gates, latches, and decoders with one device, while retaining the JTAG-driven ISP that enables field firmware updates.
Được đề xuất
Address Decoding and Memory Bank Selection
The EPM7160ELC84-20 is well suited for address decoding in microprocessor and DSP systems where multiple memory banks, peripherals, or I/O devices must be selected via individual chip-enable lines. Its 64 user I/O pins and 160 macrocells can decode wide address buses (24+ address lines) and generate dozens of unique chip-select outputs, replacing entire decoder ICs. The 20 ns propagation delay is fast enough to keep memory-access wait states at zero for microprocessors running up to approximately 25 MHz. Compared to discrete 74LS138/139 decoders, the CPLD consolidates multiple decode functions into one device and lets designers re-map the memory map via JTAG without board rework.
Được đề xuất
Bus Arbitration and Interrupt Steering
The EPM7160ELC84-20 fits bus arbitration and interrupt-priority encoding in multi-master systems because its macrocell-based architecture provides deterministic, fixed-latency logic with no race conditions. With 64 I/O pins and four global clock inputs, it can monitor multiple bus-request and grant signals simultaneously while steering prioritized interrupts to a host CPU. The MAX 7000 architecture's predictable timing simplifies worst-case latency analysis required for arbitration protocols. Compared to discrete priority encoders and latches, the CPLD adds JTAG visibility into internal states for debug and supports in-system re-tuning of arbitration policies.
Được đề xuất
Register-Based I/O Expansion
The EPM7160ELC84-20 enables register-based I/O expansion for microcontrollers and microprocessors with insufficient native GPIO pins by emulating parallel-port expanders, shift-register chains, or addressable I/O blocks. Each of its 64 user I/O pins can be configured as input, output, or bidirectional, with optional weak pull-ups, supporting direct LED driving, relay control, or button-matrix scanning. With 5.0-V tolerant I/O, the CPLD interfaces directly with 5-V peripherals without external buffers. Compared to dedicated I/O expander ICs, the EPM7160ELC84-20 offers more flexibility in pin assignment and timing behavior via JTAG reconfiguration.
Được đề xuất
JTAG-Driven Board-Level Test Infrastructure
The EPM7160ELC84-20's built-in IEEE 1149.1 JTAG interface makes it a natural boundary-scan controller and test-access port for board-level manufacturing test. By configuring its I/O pins in boundary-scan mode, the CPLD can interconnect nets between JTAG-controlled devices, isolating faults and exercising signals without physical probe access. The 5.0-V ISP capability also lets manufacturers program the device on-board during the assembly flow, eliminating pre-programming steps. Compared to dedicated boundary-scan controllers, the EPM7160ELC84-20 doubles as functional logic plus JTAG infrastructure in one device.
Được đề xuất
State Machine and Protocol Conversion
The EPM7160ELC84-20 fits finite state machine and protocol-bridge applications such as UART-to-parallel, SPI-to-I2C, or parallel-to-PCM conversion because its macrocells are optimized for registered logic with clock-enable and reset control. The 4 Logic Array Blocks partition complex state machines into manageable sections, while 20 ns delay supports protocols up to about 25 MHz. Compared to microcontrollers running state-machine firmware, the CPLD offers deterministic timing unaffected by interrupt latency, and starts executing at power-on without code-boot delays. JTAG ISP allows protocol upgrades in the field.
Được đề xuất
Legacy Industrial Control Replacement
The EPM7160ELC84-20 is commonly used as a form-fit-function replacement for obsolete discrete logic boards in legacy industrial control systems because its PLCC-84 package fits existing sockets and footprints. With 160 macrocells and 64 I/O pins, it can replicate dozens of legacy 74LS/74HC ICs in a single device, simplifying maintenance and reducing downtime. Its commercial temperature grade suits factory-floor environments. Compared to redesigning around modern FPGAs, the EPM7160ELC84-20 enables drop-in retrofits that preserve wiring, connectors, and system behavior while modernizing internal logic.

Ghi chú thiết kế
The EPM7160ELC84-20 requires a stable 5.0 V ±5% supply at VCC pins 21, 41, 61, and 84. Place one 0.1 uF ceramic decoupling capacitor adjacent to each VCC pin and a single 10 uF bulk tantalum or low-ESR ceramic capacitor near the device. Insufficient decoupling can cause ISP programming failures and intermittent logic errors during high-frequency I/O switching. VCC must rise monotonically on power-up for reliable initialization - add a reset supervisor if the upstream regulator has slow or non-monotonic startup.
For PLCC-84 layout, follow the JEDEC standard land pattern with 1.27 mm pitch and exposed pad geometry compatible with both socketed and direct-solder assembly. When using a PLCC socket, retain the socket's recommended PCB pad pattern and ensure mechanical retention clips are present to prevent vibration-induced contact failures. Keep JTAG traces (TDI, TDO, TMS, TCK) short and route them on an inner or outer layer with no stubs; add 10 kohm pull-ups on TMS and TDI per JTAG convention to keep the TAP controller in a known state at power-up.
Do not substitute the EPM7160ELC84-20 with the EPM7160SLC84-6 directly - despite sharing the PLCC-84 footprint, the SL variant operates at 3.3 V and will be damaged by a 5.0 V supply. When migrating to industrial temperature, the EPM7160ELI84-20 is drop-in compatible but has slightly different DC characteristics; verify timing margins across the full -40C to +85C range. For unused I/O pins, configure them as outputs driving low or as inputs with weak pull-ups enabled - never leave them floating to avoid quiescent-current spikes.
The MAX 7000 macrocell output slew rate is approximately 1-2 ns; output pins can generate fast edges that couple into adjacent traces. Maintain at least 3W (where W = trace width to substrate) spacing between high-speed outputs and sensitive analog signals, and use a ground plane on an adjacent layer to provide return-current paths. For clock outputs above 33 MHz, consider adding 22-33 ohm series damping resistors to reduce reflections on longer traces.
