EPM7128STC100-6 概要
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like logic blocks on a single chip with a programmable interconnect matrix. CPLDs sit in the programmable logic hierarchy between small SPLDs and large FPGAs: they offer deterministic, fast input-to-output timing (a few nanoseconds), instant-on configuration from on-chip EEPROM, and are widely used for glue logic, bus interfacing, address decoding, and state-machine replacement. The MAX 7000S family uses Altera's second-generation MAX architecture with each macrocell containing a programmable AND/OR/expanders array and a configurable flip-flop.
Key features include 6 ns tPD (commercial speed grade -6), 147.1 MHz fCNT internal counter frequency, 100% tested PCI-compliant timing in -6/-7/-10 speed grades for 33 MHz PCI Local Bus Revision 2.2, JTAG boundary-scan test support, and four-pin JTAG ISP. Each macrocell provides up to 36 product terms, and the device supports programmable power-saving modes that cut standby current by 50% or more on unused macrocells.
The MAX 7000S architecture employs a classic EEPROM-based configuration cell, a fast interconnect matrix (FastTrack), and individual macrocell registers. The 5 V core and I/O make this device suitable for legacy 5 V systems where modern 3.3 V or 1.8 V CPLDs cannot interface directly. The 100-pin TQFP package has a 1.0 mm lead pitch and supports surface-mount reflow assembly on standard FR-4 boards.
Typical applications include 5 V system glue logic, address decoding and chip-select generation, asynchronous state machines, bus arbitration logic, 33 MHz PCI interface glue, industrial control replacement of discrete TTL/CMOS logic, and JTAG-configurable I/O expansion. The instant-on behavior makes it ideal for boot-ROM replacement, power-sequencing controllers, and reset-distribution networks.
When designing with this device, observe the 5 V VCC tolerance and ensure 5 V-tolerant I/O are not exposed to higher-voltage signals. Use the Quartus Prime (or legacy MAX+PLUS II) toolchain for design entry, fitting, and JTAG programming, and budget JTAG chain length when cascading multiple MAX 7000S devices on a single scan chain.
This page synthesizes distributor pricing, verified drop-in alternatives, and JTAG programming guidance not found in the manufacturer datasheet - helping engineers accelerate board bring-up and second-source the device across MAX 7000S speed grades.

主な用途
EPM7128STC100-6 の用途: 6 件s: 5 V System Glue Logic and Bus Decoding, PCI Local Bus 33 MHz Interface Logic, Industrial Control and PLC Logic Replacement, Boot ROM Replacement and Power Sequencing, JTAG-Configurable I/O Expansion, Legacy Design Maintenance and Second-Sourcing.
5 V System Glue Logic and Bus Decoding
The EPM7128STC100-6 excels as 5 V bus glue logic, replacing dozens of 74-series TTL/CMOS packages with a single programmable device. Its 128 macrocells and 84 user I/Os deliver sufficient capacity for full address decoding, chip-select generation, and wait-state insertion across legacy 8/16/32-bit microprocessor buses. The 6 ns pin-to-pin delay ensures decoded signals meet timing without inserting wait states. The 5 V I/O tolerance is critical because it directly interfaces with 5 V memory, peripherals, and legacy microcontrollers without level shifters. The instant-on EEPROM configuration eliminates boot-loader complexity and provides deterministic power-on behavior required in industrial and automotive controllers.
おすすめ
PCI Local Bus 33 MHz Interface Logic
The EPM7128STC100-6 supports 33 MHz PCI Local Bus Specification Revision 2.2 timing in the -6, -7, and -10 speed grades, making it suitable for PCI bus arbitration, address decoding, and signal steering logic in PCI add-in cards and embedded systems. Its 6 ns tPD meets the 33 MHz PCI clock-to-output budget for address/data steering. The 5 V I/O natively drives PCI bus signals, and the 84 user I/Os accommodate multiple PCI device selects plus interrupt steering. For legacy PCI designs that must remain 5 V compliant, the -6 is one of the few CPLDs still qualified for new PCI board production.
おすすめ
Industrial Control and PLC Logic Replacement
In industrial controllers and PLCs, the EPM7128STC100-6 consolidates discrete logic functions such as relay driving, encoder decoding, sensor signal conditioning, and PWM generation into a single reprogrammable device. Its 128 macrocells handle multiple independent state machines for motion control, while the 5 V tolerance directly interfaces with industrial 24 V sensor inputs (after external level shifting). The EEPROM-based configuration is field-updatable via JTAG, allowing firmware revisions without board removal. Industrial-grade (-10, -15) and lead-free variants are widely deployed in long-life-cycle factory automation equipment.
おすすめ
Boot ROM Replacement and Power Sequencing
The EPM7128STC100-6 is widely used to replace small parallel boot ROMs/Flash in embedded systems where instant-on behavior is required. Unlike serial configuration devices used with FPGAs, the EPM7128STC100-6's on-chip EEPROM eliminates boot latency and provides deterministic outputs at power-up. It also serves as a power-sequencing controller, generating staggered reset and enable signals for multi-rail systems (e.g., 1.8 V core, 3.3 V I/O, 5 V analog) with millisecond-scale programmable delays. The 6 ns tPD ensures reset propagation stays well within system timing budgets.
おすすめ
JTAG-Configurable I/O Expansion
Designers use the EPM7128STC100-6 as a JTAG-driven I/O expander to add configurable digital I/O to microcontrollers or ASICs that lack sufficient pins. The 84 user I/Os can be reconfigured in-circuit via the JTAG chain without firmware changes, providing flexibility for prototype development and field upgrades. The 5 V tolerance is compatible with most legacy MCUs, and the 147.1 MHz internal frequency supports fast bit-banging protocols. The SameFrame pin-out feature lets designs scale between TQFP-100 and larger packages without layout changes.
おすすめ
Legacy Design Maintenance and Second-Sourcing
For engineers maintaining legacy 5 V designs originally built around the EPM7128STC100-6, the part family provides robust second-sourcing through multiple speed grades and lead-free variants in the identical 100-pin TQFP footprint. The EPM7128STC100-7, -10, and -6N variants are pin-compatible drop-in replacements, allowing procurement flexibility and lifecycle extension when the original -6 is hard to source or counterfeit risk is a concern. The mature Quartus Prime and legacy MAX+PLUS II toolchains continue to support all variants, ensuring existing IP and bitstreams can be retargeted without redesign.

設計ノート
The EPM7128STC100-6 requires both VCCINT (5 V core) and VCCIO (5 V I/O) supplies; both must be decoupled with 0.1 uF ceramic capacitors placed within 5 mm of each supply pin, plus a bulk 10-47 uF tantalum or aluminum electrolytic capacitor on each supply rail. Power sequencing between VCCINT and VCCIO is not required - the device tolerates simultaneous or VCCIO-first ramp-up. Use a separate analog ground plane if mixing analog and digital signals, but the MAX 7000S is a fully digital device and does not require a quiet analog supply.
The 100-pin TQFP package has a 1.0 mm lead pitch and 0.5 mm lead width - use a PCB footprint with 0.4 mm pad width and 1.0 mm pitch to ensure reliable solder fillets. The TQFP-100 thermal pad is not present on this package; thermal dissipation is via the leads and a copper pour of at least 100 mm^2 on the top layer is recommended. Use 4-mil (0.1 mm) trace-and-space design rules on inner layers; outer layers can use 6-mil traces for signal routing. Avoid running long parallel traces between JTAG pins and high-speed I/O to prevent coupling.
The EPM7128STC100-6 supports 33 MHz PCI Local Bus timing only when the -6, -7, or -10 speed grade is used with proper board layout - keep PCI clock and control trace lengths matched within 1.27 cm (500 mil) of each other. Series-damping resistors (22-33 ohm) on PCI outputs may be needed to control ringing on long backplane traces. For non-PCI applications, the 6 ns tPD still requires controlled-impedance traces (50 ohm microstrip) for clock signals above 50 MHz. All unused I/O pins should be configured as outputs driving low or as inputs with internal pull-ups to minimize supply current.
Do not connect 3.3 V signals directly to the EPM7128STC100-6's 5 V I/O - the device's input VIH is 2.0 V (TTL-compatible), so 3.3 V signals may be accepted, but VOH will still drive 5 V logic levels and may damage downstream 3.3 V components. Use a level shifter or a 3.3 V-tolerant CPLD variant for mixed-voltage designs. Do not assume the legacy MAX+PLUS II software can synthesize modern SystemVerilog or VHDL-2008 constructs - the Quartus Prime toolchain is recommended for new designs and supports the legacy EPM7128STC100-6 device family through the MAX 7000S device support file. Counterfeit risk is elevated for non-RoHS EPM7128STC100-6 stock purchased from brokers - buy from authorized distributors or verify x-ray decapsulation.
コンプライアンス情報
The legacy EPM7128STC100-6 is non-RoHS (contains lead). The lead-free EPM7128STC100-6N variant is RoHS-compliant. Both versions are not AEC-Q100 qualified for automotive applications.
