EPM7160STC100-10 - MAX 7000S CPLD, 160 Macrocells, 100-pin TQFP | Intel
The Intel (formerly Altera) EPM7160STC100-10 is a high-density, high-performance EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 7000S family, featuring 160 macrocells, 84 user I/Os, and 3.2K usable gates in a 100-pin TQFP package with a 10 ns pin-to-pin propagation delay and 5.0 V operation. The device is fabricated in advanced CMOS technology and supports in-system programmability (ISP) through the IEEE Std. 1149.1 JTAG interface, allowing field upgrades without removing the part from the board. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays on a single chip with a programmable interconnect matrix. In the system hierarchy, a CPLD sits between simple SPLDs (PALs/GALs) and larger FPGAs, offering deterministic timing, instant-on behavior from non-volatile EEPROM, and typically lower I/O counts than FPGAs but higher logic density than 22V10-style GALs. The MAX 7000S family is Altera's second-generation MAX architecture, characterized by fast 5-10 ns propagation delays and pin-compatible upgrades within the family. Key features of the EPM7160STC100-10 include 160 macrocells organized in logic array blocks (LABs), 84 user I/Os, 3.2K usable gates, a 100 MHz internal counter frequency, and 5.0 V VCC operation. The -10 speed grade denotes a 10 ns maximum pin-to-pin delay (tPD1) and a 6 ns global clock setup time, suitable for glue-logic, bus-interface, and state-machine applications where deterministic timing is critical. The device also offers programmable power savings with 50% or 100% toggle-rate reduction modes, multi-voltage I/O support, and JTAG boundary-scan test compliance. Architecturally, the EPM7160STC100-10 uses an EEPROM cell to store the configuration, which means the device powers up instantly in a known state without external boot memory. Each macrocell contains a programmable AND/OR array, a product-term allocator, a flip-flop, and an I/O control block, providing both combinational and registered logic with flexible feedback paths. The interconnect uses Altera's FastTrack continuous interconnect matrix, minimizing routing delay variations across the chip. Typical applications include bus-interface bridging (e.g., 8-bit/16-bit MCU to 32-bit peripheral glue-logic), address decoding and chip-select generation in microprocessor systems, state-machine control for industrial automation, peripheral interface adaptation (UART, SPI, I2C, parallel buses), and legacy TTL/CMOS logic integration on a single programmable device. The instant-on EEPROM configuration also suits safety-critical and automotive underhood applications requiring deterministic power-up behavior. Designers should note that the EPM7160STC100-10 belongs to a mature, multi-decade product family; some speed grades and temperature grades have been migrated to the -10N suffix variant. For new designs, evaluate MAX II or MAX V CPLDs as modern equivalents, but for pin-compatible drop-in replacement on existing PCBs the EPM7160STC100-10N, EPM7160STC100-7, and EPM7160STC100-15 offer parametric-equivalent second sources within the same 100-pin TQFP footprint.

Built on a 5 V CMOS process, this non-volatile EEPROM-based device provides in-system programmability via IEEE Std. 1149.1 (JTAG) and supports the SameFrame pin-out migration strategy that allows multiple MAX 7000S densities to share a common PCB layout. A CPLD (Complex Programmable Logic Device) is a non-volatile, flash/EEPROM-backed programmable logic device that combines the deterministic timing of PAL/GAL architecture with higher logic density, multi-level macrocell arrays, and on-chip programmable interconnect. CPLDs sit between discrete logic ICs (74-series gates) and FPGAs in the programmable logic hierarchy: FPGAs offer higher density and richer features but require external boot memory and have unpredictable timing; CPLDs boot instantly from on-chip non-volatile memory and deliver predictable pin-to-pin delays of a few nanoseconds. The MAX 7000S family is the second-generation MAX architecture, optimized for 5 V system designs requiring glue logic, bus decoding, state-machine control, and high-speed interface bridging. Key features include 84 user I/O pins (5 V tolerant), four dedicated inputs, programmable power-saving mode per macrocell, programmable security bit for design protection, in-system programmability through the JTAG interface, and a multi-volt I/O interface that allows mixed-voltage operation with 5.0 V, 3.3 V, and 2.5 V devices on the same board. The 10 ns pin-to-pin delay translates to approximately 100 MHz system frequency on combinatorial paths, sufficient for fast state-machine and address-decoding tasks. Typical applications include bus-interface bridging (PCI, ISA, VME), address decoding and chip-select generation, high-speed glue logic replacement for 74-series TTL/CMOS gates, state-machine controllers, and 5 V industrial control systems that need non-volatile, instant-on programmable logic. The SameFrame pin-out enables migration across MAX 7000S variants (EPM7128S, EPM7160S, EPM7192S, EPM7256S) on the same 100-pin TQFP footprint, allowing designers to swap densities without PCB rework. When designing with this device, ensure the JTAG chain is correctly terminated with the TCK, TMS, TDI, and TDO pins accessible for ISP. Use Altera/Intel Quartus II (or legacy MAX+PLUS II) for design entry, fitting, and programming; the device supports both 4-pin JTAG and ByteBlaster programming modes. Verify that the 5 V supply is well-decoupled with 100 nF + 10 µF capacitors near the VCC pins.

The -10 speed grade denotes a 10 ns tPD maximum, suitable for 66 MHz PCI bus interfaces and high-speed glue-logic replacement. Per the verified chip-source summary, the device offers an internal frequency of 167 MHz and 64 user I/Os within a plastic LCC-84 footprint variant context; the -10N TQFP-100 variant aligns with the broader MAX 7000S pinout family. The architecture combines four Logic Array Blocks (LABs) connected through a Programmable Interconnect Array (PIA), with each macrocell containing a programmable AND/OR array, a flip-flop, and routing to global or local control signals. The EEPROM configuration cell is non-volatile, allowing instant-on behavior at power-up with no external boot PROM. ISP via JTAG enables field upgrades without removing the device from the board. Typical applications include PCI bus interface bridging, address decoding and glue-logic replacement, peripheral adapters, and 5 V/3.3 V mixed-voltage system controllers. The wide operating temperature (commercial 0C to 70C) and the legacy MAX 7000S family heritage make it a drop-in solution for industrial and embedded designs that have long service-life requirements. When designing with this part, route JTAG signals TMS, TCK, TDI, TDO through dedicated test access pins and provide a clean 5 V supply with adequate decoupling. Verify pin compatibility with the specific TQFP-100 footprint revision on your PCB before committing to layout, since the MAX 7000S family includes several die/package variants with different I/O counts and ball/pin assignments.

Built on a CMOS EEPROM process with second-generation MAX architecture, the device provides predictable timing with 4 ns global propagation delay and a fixed-pin architecture that simplifies PCB design. Multiple I/O banks support mixed-voltage interfacing, and the JTAG port enables post-assembly reconfiguration without removing the part from the board. Typical applications include bus-interface bridging (e.g., address decoding for legacy microcontrollers), peripheral glue logic, power-sequencer controllers, and interface translation between 5V and 3.3V logic domains. Industrial and consumer control boards commonly use this part for deterministic state-machine implementation. When designing with this part, allocate JTAG pins (TDI, TDO, TMS, TCK) early in the schematic, because reassigning them mid-layout complicates the JTAG chain. The device is non-volatile, so configuration loads instantly on power-up, eliminating the boot-time delay common to FPGAs.

The 'E' suffix denotes the enhanced MAX 7000E architecture with in-system programmability (ISP) via the built-in IEEE Std. 1149.1 JTAG interface, and 'GC160' identifies the ceramic pin-grid-array package. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on programmable logic device built from multiple PAL-like logic array blocks (LABs) joined by a central interconnect matrix. CPLDs sit hierarchically above simple PLDs (PAL/GAL) and below FPGAs, offering deterministic timing, fast I/O, and instant-on behavior with no configuration memory load time. They are widely used as glue logic, bus interfaces, and state-machine controllers. Key features of the EPM7192EGC160-12 include 192 macrocells across 4 logic array blocks (LABs) with 3.75K usable gates, 124 user I/O pins, 12 ns tPD propagation delay, and a 76.9 MHz maximum operating frequency per the manufacturer datasheet. The device operates from a single 5.0 V supply (4.75 V to 5.25 V) and supports 5.0 V in-system programmability through the JTAG-compliant IEEE 1149.1 boundary-scan test (BST) interface. The MAX 7000 family supports PCI Local Bus Specification Revision 2.2 timing compatibility in -4 to -10 speed grades. The MAX 7000 architecture combines EEPROM configuration memory (non-volatile) with a classic product-term / macrocell structure, delivering zero standby power for the configuration and deterministic 12 ns combinational delay regardless of how the design routes through the interconnect. This makes the EPM7192EGC160-12 especially attractive for legacy industrial designs that need robust, repeatable timing rather than the absolute logic density of an FPGA. Typical applications include industrial glue logic and bus-interface bridging, telecom backplane control, PCI bus interface glue, address decoding and DMA control in legacy embedded systems, and motor-control I/O expansion. Designers also use the EPM7192E in production ASIC prototyping where instant-on, non-volatile behavior is required. A key design consideration is the 160-pin PGA footprint: although it shares a pin count with some MAX 7000 variants in PQFP packages, the ceramic PGA is socket-friendly and well-suited for legacy / through-hole backplane designs, but it requires a different PCB land pattern than the PQFP / TQFP / QFP variants of the same die. Designers migrating between package options should verify the footprint before reassigning the BOM.

The device provides predictable timing with fixed propagation delays, multi-voltage I/O support for 3.3 V and 5 V interfaces, and a programmable power-saving mode that reduces individual macrocell power when logic is idle, while an enhanced security bit protects user designs from unauthorized read-back. The MAX 7000 architecture implements each macrocell as a product-term array feeding a programmable register, with a shared programmable interconnect array (PIA) routing signals between LABs. The EEPROM process technology allows unlimited reconfiguration cycles via JTAG, supporting field upgrades and rapid prototyping.

In the broader system hierarchy, the EPM7192EQC160-20 sits between small FPGAs and discrete logic ICs, offering instant-on behavior (no boot PROM required), predictable timing for register-rich designs, and 5 V tolerant I/Os that are increasingly rare in modern logic families. Key features include 192 macrocells distributed across 4 Logic Array Blocks, 36 I/O pins routed through programmable interconnect, programmable power-saving mode per macrocell, programmable security bit for design protection, and JTAG-based ISP that allows board-level reconfiguration without removing the device. The 20 ns speed grade provides a 50 MHz fCNT internal counter frequency and supports combinatorial and registered logic at typical 5 V system clocks. Architecturally, the MAX 7000 family uses second-generation MAX architecture with EEPROM process technology, providing non-volatile configuration storage that retains state through power cycles. The Programmable Interconnect Array (PIA) routes signals between LABs and I/O pins with predictable delays that simplify static-timing closure versus SRAM-based FPGAs. Each macrocell contains a programmable AND/OR array plus a configurable flip-flop that can be bypassed for pure combinatorial outputs. Typical applications include industrial control glue-logic, 5 V system bus interfacing, JTAG-controlled I/O expansion, address decoding for legacy microprocessor boards, and pin-compatible replacement for older MAX 7000 designs where instant-on, non-volatile configuration is required. The wide 5 V tolerance makes it especially attractive for industrial 5 V designs where 3.3 V-only modern CPLDs are unsuitable. When designing with this part, note that the PQFP-160 package requires fine-pitch PCB layout with controlled-impedance traces; place decoupling capacitors (0.1 uF and 10 uF) as close as possible to each VCC/GND pair, and use a JTAG header that meets IEEE 1149.1 specifications for in-system programming access. Verify the JTAG chain length and TCK pull-up/down values against the JTAG specification for reliable ISP operation.

The device supports multiple I/O standards including 5.0 V CMOS and 3.3 V PCI-compatible signaling through its JTAG-configurable I/O structure. The MAX 7000S architecture provides predictable, deterministic timing because every logic path traverses the same predictable interconnect structure — unlike SRAM-based FPGAs that require device configuration on power-up. This makes the EPM7192SQC160-10N particularly well-suited to applications where instant-on behavior is critical and where designers need fixed propagation delays for worst-case timing analysis. The 10 ns tPD (pin-to-pin delay) of this -10N speed grade supports clock frequencies up to 100 MHz in combinatorial paths.

Designers frequently choose this part when they need non-volatile, deterministic logic with the convenience of JTAG in-system reprogrammability. When designing with this device, pay careful attention to I/O bank supply pin requirements — VCCINT and VCCIO may need separate rails depending on the mixed-voltage interface scheme, and unused pins should be configured as outputs driving ground to minimize power. The 160-pin PQFP footprint requires careful PCB routing given the 0.65 mm pitch; an external JTAG header is recommended for ISP access during prototyping and field firmware updates.

Per the manufacturer description on Arrow and Heisener, the part is a 5K-gate, 256-macrocell, 126.6 MHz MAX 7000A device in a 100-pin FBGA tray. 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. In the broader taxonomy, a CPLD sits between a small FPGA and a discrete gate array: it provides deterministic, propagation-delay-based timing (often called "PAL-like" timing) with instant-on, flash- or EPROM-backed configuration. Designers typically use a CPLD when the design is dominated by wide combinational logic, decoders, and registered I/O - exactly the use cases the MAX 7000A family was designed for. The EPM7256AEFI100-7 features 256 macrocells organized in logic array blocks (LABs), each containing 16 macrocells, with a programmable interconnect array (PIA) routing signals between LABs and to the I/O pins. The device supports JTAG-based IEEE 1149.1 boundary-scan test and in-system programmability through Altera's legacy programming tools (MAX+PLUS II or Quartus II). MultiVolt I/O supports interfacing to 2.5 V, 3.3 V, and 5.0 V logic families without external level shifters, which is critical when bridging legacy 5 V peripherals to modern 3.3 V processors. Typical applications include PCI/ISA bus address decoding and chip-select generation, asynchronous state machines for industrial controllers, I/O expansion and level translation between 5 V and 3.3 V domains, and configuration/reset sequencing for microprocessors and DSPs. The 100-ball FBGA package provides high board-density routing for designs that need all 84 I/O on a small PCB footprint. When designing with this part, ensure the JTAG chain order matches the BSDL file order in the Altera documentation. Decoupling must use 0.1 uF and 0.01 uF ceramic capacitors placed within 5 mm of each supply ball. Quiescent current for the MAX 7000A family is in the tens of milliamps; thermal dissipation is usually not a concern at typical clock rates, but junction temperature must stay within the -40 C to +85 C industrial range.

The Altera (Intel Programmable Solutions Group) EPM7256AEFI256-7 is a high-density member of the MAX 7000A family of CMOS Complex Programmable Logic Devices (CPLDs), packaged in a 256-pin Fine-pitch Ball Grid Array (FBGA) with 256 macro cells, 164 user I/Os, and 5,000 usable gates, operating from a 3.0V to 3.6V core supply. The -7 speed grade delivers a maximum pin-to-pin propagation delay (tPD) of 7.5 ns and a maximum counter frequency (fCNT) of 126.6 MHz, with PCI-compatible timing in the -4, -5, -6, and -7 speed grades per the PCI Local Bus Specification, Revision 2.2. The device is in-system programmable through the IEEE 1149.1 (JTAG) interface and supports the 4-pin JTAG protocol for boundary-scan test. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays on a single chip with a programmable interconnect network. CPLDs sit between simple SPLDs/PLDs and higher-density FPGAs in the programmable logic hierarchy, providing deterministic, predictable timing (typically 1 to 10 ns propagation delays), instant-on behavior from on-chip EEPROM, and a Logic Element Block (LEB) architecture suited to glue-logic, decoder, bus-interface, and state-machine replacement. The MAX 7000A family in particular targets PCI bus interface, peripheral bridging, and bus-arbiter designs where 5V-tolerant I/O and 3.3V core operation are required. Key features of the EPM7256AEFI256-7 include 16 Logic Array Blocks (LABs), each containing 16 macro cells for a total of 256 macro cells; 164 programmable I/O pins shared with dedicated JTAG and global control functions; in-system programmability (ISP) via JTAG; multi-volt I/O supporting 2.5V/3.3V/5.0V mixed-voltage interfacing; and a commercial operating-temperature grade of -40C to +85C. The device is PCI SIG-compliant for 33 MHz PCI 2.2 bus use in the -7 speed grade, making it a natural fit for legacy PCI add-in cards and embedded peripheral controllers. The architecture is built on a CMOS EEPROM-based macrocell fabric with a unified interconnect matrix that delivers fixed, deterministic propagation delays independent of routing density, in contrast to SRAM-based FPGAs whose timing depends on placement and routing. Each macro cell contains a programmable AND/OR array, a flip-flop, and a programmable output enable. The 256-pin FBGA package provides high I/O density for glue-logic-heavy designs and is footprint-compatible with other EPM7256AEFI256-xx speed-grade and temperature-grade variants in the same family. Typical applications include PCI peripheral interface logic (33 MHz), glue logic for microprocessor and DSP systems, bus decoders and arbiters, peripheral bus-bridges between ISA/PCI and local microcontrollers, state-machine and sequencer replacement in industrial controllers, and JTAG-based boundary-scan chain extension for board-level test. Designers migrating from 5V-only legacy PLDs use the MAX 7000A's mixed-voltage I/O to bridge 5V peripherals to a 3.3V core without external translators. When designing with this part, plan for a clean 3.3V rail with adequate bulk decoupling on each FBGA power pin pair (VCCINT and VCCIO), because the FBGA package's multi-row ball array requires careful PCB fan-out. Use the Quartus II or MAX+PLUS II design software for fitting, simulation, and JTAG programming; legacy MAX+PLUS II projects must be migrated to Quartus II for newer tool support. Always verify that the I/O bank voltage matches the driven peripheral's VOH/VOL requirements, as the multi-volt I/O core uses separate VCCIO rails per bank.

EPM7256AEQC208-5N - MAX 7000A CPLD, 256 Macro, 5ns | Intel
The Intel (formerly Altera) EPM7256AEQC208-5N is a high-density CMOS Complex Programmable Logic Device (CPLD) from the MAX 7000A family, delivering 5,000 usable gates, 256 macrocells, and 164 user I/Os in a 208-pin PQFP package with -5 speed grade (5.5 ns pin-to-pin propagation delay). It operates from a 3.3 V core supply and supports in-system programmability via the IEEE Std. 1149.1 (JTAG) interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL devices and high-density FPGAs in the programmable logic hierarchy: SPLD -> CPLD -> FPGA. Unlike SRAM-based FPGAs, MAX 7000A devices use EEPROM configuration cells that retain the bitstream without external memory, enabling instant-on behavior. Within the broader taxonomy of digital semiconductors, the EPM7256AEQC208-5N belongs to programmable logic -> logic ICs -> integrated circuits. Key features include a maximum internal frequency of 172.4 MHz, a 4.5 ns registered propagation delay, and 16 dedicated input pins plus 164 bidirectional I/O pins. The architecture combines the FastTrack interconnect matrix with each macrocell containing a programmable AND/OR array, a product-term allocator, and a flipflop. The 3.3 V supply reduces power consumption by approximately 50% versus the legacy 5 V MAX 7000 family while preserving pin compatibility with existing designs. Typical applications include bus interface bridging, glue-logic consolidation, peripheral I/O expansion, and control-state-machine implementation in telecom, industrial, and embedded systems. Designers use the part to replace discrete 74LS/74HC logic, reducing board area and BOM cost. The JTAG chain and built-in ISP (In-System Programmability) enable field firmware updates without removing the device from the board, a key advantage in deployed systems. When designing with this device, ensure the Quartus II / MAX+PLUS II design software is used for fitting and that the JTAG pins (TDI/TDO/TMS/TCK) are pulled to valid logic levels through 10 kohm resistors. The PQFP-208 footprint requires a 0.5 mm lead pitch and IPC-7351 land patterns, and the device is rated for commercial temperature operation (0 C to +70 C).

EPM7256AEQI208-7N - 256-Macrocell 3.3V CPLD | Altera
The Altera EPM7256AEQI208-7N is a MAX 7000A-family Complex Programmable Logic Device (CPLD) offering 256 macrocells, 164 user I/O pins, and 5,000 usable gates with a 7.5 ns pin-to-pin propagation delay, housed in a 208-pin PQFP (FQFP) package. It operates from a 3.3 V supply and is rated for the industrial temperature range. A CPLD (Complex Programmable Logic Device) is a programmable logic IC built from an array of macrocells and a programmable interconnect matrix. Unlike an FPGA, which uses SRAM configuration and volatile lookup tables, the MAX 7000A family is EEPROM-based, so the configuration is retained without an external boot device. In the logic hierarchy, a CPLD sits between discrete glue logic and full FPGAs: CPLD -> programmable logic device (PLD) -> digital logic IC -> semiconductor. Key features of the EPM7256AEQI208-7N include 256 macrocells organized into 16 logic array blocks, 164 I/O pins, a maximum internal frequency of 126.6 MHz, and a 7.5 ns pin-to-pin delay. The 3.3 V core keeps dynamic power low while remaining 5 V tolerant on I/O, simplifying mixed-voltage board design. EEPROM configuration means the device is live within microseconds of power-up, which is critical for power sequencing and bus arbitration logic. The MAX 7000A architecture uses product-term logic with programmable interconnect, giving deterministic, predictable timing - a key advantage over SRAM-based FPGAs for control-path logic. The 208-pin PQFP package provides ample I/O for bus bridging and glue-logic consolidation. Typical applications include PCI/ISA bus interface logic, DSP and microcontroller glue logic, power-up sequencing controllers, and legacy industrial control boards. The industrial temperature rating supports factory automation and telecom line-card environments. When designing with this device, note that it is a mature, non-volatile part; verify lifecycle status before committing to new production, and confirm the 7.5 ns speed grade meets your critical path.
