EPM7128SQC160-15N 개요
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on characteristics of PAL/GAL architecture with the density of a small FPGA. Within the broader programmable-logic taxonomy, CPLDs sit between discrete PALs (small, simple, fast) and FPGAs (large, register-rich, SRAM-based). The MAX 7000 family was Altera's second-generation CPLD architecture (succeeding the classic MAX 5000/9000) and introduced the multi-matrix interconnect plus ISP (in-system programmability) via JTAG, features that made it the de-facto industry standard for glue logic from the mid-1990s onward.
Key features of the EPM7128SQC160-15N include 128 macrocells arranged in 8 logic array blocks (LABs), 100 user I/O pins, 15ns combinatorial propagation delay, a maximum internal counter frequency of 76.9 MHz, and 5V-tolerant I/O supporting both 3.3V and 5V mixed-voltage systems. The device is non-volatile (EEPROM-based) so the configuration is retained without an external boot PROM, and it supports in-system programming via the JTAG-compatible 4-pin interface. Programmable interconnect allows wide AND-OR logic functions across LABs with predictable timing.
The architecture uses Altera's classic MAX (Multiple Array matriX) routing structure: each LAB contains 16 macrocells that share a programmable interconnect array, and LABs communicate through the PIA (Programmable Interconnect Array). This gives the EPM7128SQC160-15N deterministic, pin-locked timing that does not change with routing density - a property that distinguishes CPLDs from SRAM-based FPGAs where delay varies with placement.
Typical applications include bus-interface bridging (PCI/ISA glue logic), address decoding and chip-select generation, power-up sequencing and reset distribution, motor control peripheral logic, industrial PLC I/O expansion, and replacement of multiple discrete TTL/CMOS logic packages. The wide 5V I/O tolerance is especially valued when interfacing legacy microcontrollers or bus transceivers to modern 3.3V ASICs.
When designing with this device, note that the PQFP-160 footprint has longer lead lengths than modern BGA/QFN packages, which limits high-speed signal edge rates above ~50 MHz. For new designs above 100 MHz I/O, consider migrating to a MAX V, MAX 10, or MAX II CPLD in a smaller QFN package while preserving the MAX 7000 logic architecture.

일반적인 애플리케이션
EPM7128SQC160-15N 적합 용도: 7 애플리케이션s: PCI / ISA Bus Glue Logic, Address Decoding & Chip-Select Generation, Power-Up Sequencing & Reset Distribution, Motor Control Peripheral Logic, Industrial PLC I/O Expansion, Legacy TTL / CMOS Logic Replacement, Embedded System Peripheral Bridging.
PCI / ISA Bus Glue Logic
The EPM7128SQC160-15N fits PCI/ISA bus glue-logic roles because its 128 macrocells provide ample AND-OR decoding capacity for chip-select generation, address decoding, and bus-cycle control. Its 15 ns tPD comfortably meets the 33 MHz PCI clock-to-output timing (minimum 30 ns cycle budget allows ~15 ns combinational delay), and the 100 user I/Os support the wide bus and interrupt/grant signals of legacy PC architectures. The non-volatile EEPROM configuration eliminates boot-PROM overhead - critical for instant-on BIOS extension ROMs and adapter cards. Compared to discrete 74LS/74FTTL gates, a single EPM7128SQC160-15N replaces dozens of packages, reducing PCB area and BOM cost while preserving deterministic, pin-locked timing.
추천
Address Decoding & Chip-Select Generation
The EPM7128SQC160-15N is widely deployed as an address decoder in microcontroller and embedded systems. Its wide AND-OR product-term architecture can decode large address ranges - up to the full 24- or 32-bit address space - in a single device, producing chip-select strobes for memory banks, peripherals, and I/O expanders. The 15 ns propagation delay ensures chip-selects are valid before the CPU's first memory-access cycle, eliminating wait-state insertion. Non-volatile EEPROM programming means the decoding map is fixed at power-up with no bootloader overhead. Compared to discrete 74HC138/139 decoders, the CPLD approach supports custom, non-power-of-two decode regions and reduces part count.
추천
Power-Up Sequencing & Reset Distribution
Power-up sequencing in multi-rail systems benefits from the EPM7128SQC160-15N's deterministic timing and instant-on behavior. The MAX 7000S EEPROM configuration is valid within microseconds of VCC ramp, allowing the CPLD to drive early-stage enables such as the core voltage regulator's PG (Power Good) handshakes before the main CPU resets. With 100 I/Os, it can fan out independent reset and enable signals to multiple ASICs, FPGAs, and analog rails, each gated by its own programmable time delay built from internal macrocell counters. The 5V-tolerant I/O and 3.3V/5V mixed-voltage support make it ideal for sequencing mixed-voltage boards. This usage remains common in industrial PLC backplanes and telecom line cards.
추천
Motor Control Peripheral Logic
Industrial motor drives use the EPM7128SQC160-15N as peripheral glue between a microcontroller/DSP and the power stage. Typical functions include PWM dead-time insertion, fault-input synchronization, encoder quadrature decoding, and gate-driver enable logic - all of which require deterministic, sub-microsecond timing that the 15 ns tPD comfortably provides. The 100 user I/Os interface to multiple Hall-effect sensors, encoder channels, and isolated gate drivers, while the 5V-tolerant I/O directly accepts 5V Hall/encoder signals without level shifters. The non-volatile EEPROM configuration survives factory-programmed motor profiles that must persist across power cycles. The MAX 7000S SameFrame footprint lets designers migrate to higher-density 256-macrocell MAX 7000S parts as control complexity grows.
추천
Industrial PLC I/O Expansion
PLC backplanes use the EPM7128SQC160-15N as a flexible I/O expansion and isolation interface between the central processor and field-side drivers. Its 100 user I/Os can scan a multi-module backplane, debounce mechanical contacts in hardware (via macrocell flip-flops), and present a clean register-mapped interface to the CPU. The EEPROM-based configuration lets OEMs re-flash I/O maps via JTAG without changing firmware, accelerating line-rebuild. The 5V-tolerant I/O tolerates noisy 24V field-side signals after simple resistive dividers. Industrial customers value the part's long lifecycle, wide operating range, and SameFrame migration path, even though the silicon is NRD.
추천
Legacy TTL / CMOS Logic Replacement
A classic use of the EPM7128SQC160-15N is consolidating dozens of discrete 74LS/74HC/74FTTL packages into a single programmable device, simplifying PCB layout and BOM. Its 128 macrocells typically replace 20-40 SSI/MSI packages while preserving exact logic function and timing. This reduces PCB layer count, assembly cost, and test time. The 5V I/O is directly compatible with legacy TTL thresholds, eliminating level translation. This use case is especially valuable in aerospace, defense, and industrial OEMs maintaining production of legacy systems where re-spinning a board for a different CPLD family would require re-certification. The EEPROM configuration is also more reliable than soldered-in discrete logic.
추천
Embedded System Peripheral Bridging
Bridging mismatched peripherals - for example, an 8-bit microcontroller to a 16-bit LCD bus, or a SPI master to a parallel ADC - is a natural fit for the EPM7128SQC160-15N. With 128 macrocells, the CPLD can implement protocol converters, bus-width adapters, and FIFO-like flow-control logic with deterministic timing. The 15 ns tPD easily keeps up with typical 8- and 16-bit microcontroller peripheral speeds (tens of MHz), and the 100 I/Os provide ample headroom for parallel buses. The non-volatile configuration means the bridge starts working at first power-up, even before the main CPU boots. This pattern is common in custom instrumentation and medical-device embedded boards.

설계 노트
PQFP-160 packages have long lead lengths (~3 mm) and significant lead inductance. Place at least one 0.1 µF decoupling capacitor per VCC pin, within 5 mm of the package body. Use a continuous ground plane on the layer directly beneath the CPLD to control return-current paths and EMI. Avoid routing high-speed signals (>50 MHz) under the PQFP body to limit crosstalk into the device's analog substrate.
Each EPM7128SQC160-15N user I/O can source/sink up to 25 mA DC and supports 5V TTL thresholds. When driving long PCB traces or cables, add a 33 Ω series resistor near the CPLD pin to dampen ringing. Inputs from noisy buses should be filtered with a 100 ns RC network or a Schmitt-trigger input buffer. Do not exceed the absolute maximum DC input voltage of 7V; undershoot below -2V for >100 mA / >20 ns is also prohibited.
Do not confuse the speed-grade suffix: -10 / -10N are faster than -15N. Note that VCC must rise monotonically for EPM7128A / EPM7256A devices only - this constraint does NOT apply to the non-A MAX 7000S EPM7128SQC160-15N. For ISP via JTAG, ensure TCK is not floating during board power-up; tie TCK to GND through a 10 kΩ pull-down. Always re-verify the configuration after reflow because EEPROM retention is sensitive to thermal exposure above 150 °C.
The PQFP-160 package has a thermal resistance (θJA) of approximately 35-40 °C/W on a standard 4-layer PCB. The EPM7128SQC160-15N typically dissipates 0.5-1.5 W depending on toggle frequency and IO loading. Estimate: at full 76.9 MHz toggle with 100 I/Os at 20 pF each, ICC ≈ 150-300 mA and P ≈ 0.75-1.5 W, giving a junction rise of ~30-60 °C above ambient. Ensure ambient remains below 70 °C to keep Tj within the 125 °C commercial limit.
