MPN: EPM7128SLC84-15 ⚠ Lần mua cuốiEPM7128SLC84-15 Tóm tắt
What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that sits between simple PAL/GAL devices and large SRAM-based FPGAs in the programmable logic hierarchy. CPLDs are typically used for glue logic, bus decoding, state-machine control, and I/O expansion because they offer deterministic timing, instant-on configuration (no boot PROM required), and predictable pin-to-pin delays across the whole device. Within that hierarchy, MAX 7000S is one of the longest-running Altera CPLD families, predating the modern MAX II / MAX V series.
Key features of the EPM7128SLC84-15 include 128 macrocells (2,500 usable gates), 68 user I/Os in the 84-pin PLCC footprint, a maximum internal operating frequency of up to 76.9 MHz (the -15 speed grade supports roughly 125 MHz fMAX in commercial temperature), and 4.5 ns propagation delay per pin as reported on third-party datasheet mirrors. The device is built on a 5V-tolerant CMOS EEPROM process and supports multi-volt I/O for interfacing with 3.3V and 5V logic. Programming is performed through the built-in JTAG port using Quartus or MAX+PLUS II toolchains.
Typical applications include industrial PLC and process-control glue logic, telecommunications backplane bus bridges, address decoding and wait-state generation in legacy x86 embedded systems, and ASIC-prototype logic replacement. The 84-PLCC package makes the part attractive for socketed legacy boards and field-replacement scenarios.
When designing with this device, ensure that the JTAG chain is correctly ordered if multiple devices are cascaded, and observe the I/O bank's 5V VCCIO requirement when interfacing with legacy TTL logic. The instant-on EEPROM configuration is a key advantage over SRAM-based FPGAs in safety-critical systems.

Ứng dụng tiêu biểu
EPM7128SLC84-15 phù hợp cho 6 Áp dụngs: Industrial PLC Glue Logic, Legacy x86 Embedded Bus Decoding, Telecommunications Backplane Bridging, ASIC Prototype Logic Replacement, Medical Device Interface Logic, Test & Measurement Instrument Front End.
Industrial PLC Glue Logic
The EPM7128SLC84-15 fits industrial PLC glue-logic applications because its 128 macrocells provide ample capacity to implement address decoding, bus arbitration, and custom state machines between the CPU, I/O modules, and communication ASICs, while its 5V-tolerant I/O bank eliminates level-shifters when bridging legacy TTL peripherals. The 15 ns pin-to-pin propagation delay (76.9 MHz fMAX) supports deterministic timing for scan-path control and deterministic interrupt handling in ladder-logic translation. Instant-on EEPROM configuration is critical for PLC boot sequences where SRAM-based FPGAs would require a separate boot PROM and add milliseconds to startup. Compared with a discrete 74HC logic implementation, a single EPM7128SLC84-15 replaces dozens of packages and reduces PCB area by 60-80 percent.
Được đề xuất
Legacy x86 Embedded Bus Decoding
The EPM7128SLC84-15 is ideal for legacy x86 embedded bus-decoding applications such as ISA-bus chip-select generation, wait-state insertion, and DRAM address multiplexing, where the 128 macrocells can implement wide combinational decoder logic in a single device. Its 5V VCCINT and 5V-tolerant I/O directly interface with ISA-bus signal levels without level shifters, and the 15 ns tPD provides the timing margin needed for 8 MHz and 16 MHz ISA cycles. The 84-PLCC socket-friendly package simplifies field replacement and legacy board bring-up. Compared with PAL/GAL decoding trees, the MAX 7000S reduces chip count by 5-10x and adds JTAG-reprogrammability that speeds up address-map revisions.
Được đề xuất
Telecommunications Backplane Bridging
The EPM7128SLC84-15 fits telecommunications backplane-bridging roles by providing deterministic glue logic between line cards, framer ASICs, and TDM bus switches, where the 68 user I/Os handle multi-drop backplane signals and the 5V I/O tolerance matches legacy telecom -48V-isolated logic levels. The 15 ns tPD delivers the timing margin required for T1/E1 framing strobes and HDLC control signals, and the JTAG port enables in-system firmware updates without removing line cards from service. Compared with discrete TTL, a single EPM7128SLC84-15 implements 50-100 gates of bridge logic and supports last-minute protocol revisions through JTAG reprogramming.
Được đề xuất
ASIC Prototype Logic Replacement
The EPM7128SLC84-15 functions as an ASIC prototype replacement when designers need to validate system architecture before taping out an ASIC, because the 2,500-gate capacity and JTAG-reprogrammability allow rapid architecture-iteration cycles without fab mask costs. The 15 ns tPD approximates typical ASIC gate delays, providing a realistic timing model for pre-silicon validation, while the non-volatile EEPROM ensures the prototype boots identically on every power cycle. Compared with breadboard discrete logic, the MAX 7000S shortens prototype cycles from weeks to days and provides JTAG visibility into internal nodes for debug. The 84-PLCC package also simplifies socket-swapping between prototype builds.

Medical Device Interface Logic
The EPM7128SLC84-15 supports medical device interface-logic applications such as patient-monitor front-panel controllers, infusion-pump keypad scanners, and diagnostic-instrument display drivers, where the deterministic timing and instant-on configuration are required for FDA/IEC 62304 risk-management workflows. The 5V I/O tolerance interfaces with legacy medical-instrument analog front ends, while the JTAG-reprogrammability allows field firmware updates through validated service-port procedures. Compared with discrete CMOS logic, the integrated CPLD reduces board space for portable medical devices and simplifies IEC 60601-1 EMC compliance by consolidating many logic-edge transitions into a single controlled device.
Được đề xuất
Test & Measurement Instrument Front End
The EPM7128SLC84-15 fits test-and-measurement instrument front-end designs such as oscilloscope trigger controllers, logic-analyzer pattern generators, and bench-top DMM range-switching logic, where the deterministic 15 ns pin-to-pin delay supports precise trigger-event timing and the 68 user I/Os handle multi-channel switching matrices. The 5V I/O tolerance interfaces with legacy op-amp signal-conditioning chains, while the JTAG-reprogrammability lets the OEM update trigger firmware over the instrument's existing service port without disassembling the chassis. Compared with discrete logic, the integrated CPLD reduces instrument front-end BOM by 30-40 percent and provides single-chip upgrade paths for new trigger features.

Bảo phân biệt quan trọng
- Instant-on non-volatile EEPROM configuration (no boot PROM) (vsSRAM-based FPGAs (e.g., Cyclone, Spartan families))
- 5V-tolerant multi-volt I/O directly interfaces with legacy TTL/CMOS logic (vs3.3V-only MAX V / MAX 10 CPLDs)
- Deterministic 15 ns pin-to-pin propagation delay across all 128 macrocells (vsMAX 7000E EPM7128ELC84-20)
Ghi chú thiết kế
The EPM7128SLC84-15 requires a stable 5V VCCINT supply with a recommended 100 nF decoupling capacitor within 5 mm of each VCCINT pin (pins 21 and 68) and a bulk 10 uF tantalum or ceramic capacitor on the supply rail. VCCIO (pin 48) must be tied to the same 5V rail or a 3.3V rail for multi-volt I/O operation; both supplies must ramp together within 100 ms to avoid partial-configuration latch-up. The device draws approximately 150-300 mA ICC during continuous operation depending on logic-utilization and toggle rate; budget accordingly for 5V regulators.
Place all four JTAG pins (TDI pin 1, TCK pin 43, TMS pin 63, TDO pin 83) on a dedicated JTAG header with 4.7 kΩ pull-ups on TCK and TMS per IEEE 1149.1 recommendations. Keep JTAG traces short (under 50 mm) and shielded with ground pours to prevent spurious boundary-scan entry during in-system programming. If multiple MAX 7000 devices share the JTAG chain, order TDI-to-TDO carefully and ensure the chain length does not exceed the JTAG programmer's drive capability (typically 8-16 devices).
Estimated: do not assume the EPM7128SLC84-15 is bitstream-compatible with MAX 7000AE or MAX 7000E variants. Although the 84-PLCC pinout is identical across the family, the JTAG instruction-register length and ISP (in-system programming) algorithm differ between MAX 7000, MAX 7000E, and MAX 7000S. Programming a MAX 7000S image into a MAX 7000E socket (or vice versa) will fail the IDCODE verification step. Verify the device suffix matches the compiled Quartus/MAX+PLUS II project target before production programming.
Although the 84-PLCC package has modest thermal resistance (~30 C/W junction-to-ambient with socket), the 5V VCCINT combined with high internal toggle rates can produce noticeable self-heating. Estimated: at full 76.9 MHz fMAX across all 128 macrocells, internal power dissipation may reach 0.5-0.8 W, raising junction temperature by 15-25 C above ambient. For enclosed industrial enclosures without forced airflow, derate the toggle rate or specify the industrial-temperature EPM7128ELI84-20 variant for -40C to +85C operation.
