A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EEPROM-based programmable logic device that combines multiple PAL/GAL-like macrocell arrays with a central interconnect matrix. The MAX 7000S family is built on Altera's second-generation MAX architecture with 5.0V in-system programmability (ISP), pin compatibility with the original 5.0V MAX 7000S family, and PCI Local Bus Specification Revision 2.2 compliance for the -10 speed grade. CPLDs occupy the middle ground between simple SPLDs and high-density FPGAs, delivering deterministic timing, instant-on non-volatile configuration, and high I/O count at lower cost-per-logic-block.
Key features include 3,200 usable gates, 160 macrocells, 84 user I/Os, 10ns tPD propagation delay, 100MHz maximum operating frequency, and an internal 4.75V to 5.25V supply with 5.0V-tolerant I/O. The device supports JTAG-based IEEE Std. 1149.1 boundary-scan testing and in-system programmability through the JTAG interface, eliminating the need for external programmers. The TQFP-100 surface-mount package provides a compact footprint for space-constrained designs, while the industrial -40C to +85C temperature range (denoted by the 'I' suffix) supports harsh-environment deployment.
The EPM7160STI100-10 employs Altera's classic EEPROM cell technology, retaining configuration across power cycles without external boot memory. Its deterministic routing fabric and predictable 10ns delay make it suitable for glue logic, bus interface bridging, and state-machine implementation where timing predictability is critical. The 84 available I/Os support wide bus interfaces and parallel peripheral control.
Typical applications include PCI bus interface logic, microprocessor peripheral glue logic, bus arbitration and address decoding, state-machine control in industrial automation, and high-density TTL/CMOS logic integration. The 5V core supply and 5V-tolerant I/Os align with legacy industrial and telecom infrastructure that has not yet migrated to 3.3V.
When designing with this device, plan the JTAG chain with proper TCK/TMS/TDI/TDO pull-ups and ensure the VCCIO rail matches the connected logic level. Note that the -10 speed grade supports PCI 2.2 timing.

典型應用
EPM7160STI100-10 適用於 6 應用s: PCI Bus Interface Logic, Microprocessor Peripheral Glue Logic, Industrial Automation State Machines, Bus Arbitration and Address Decoding, Legacy 5V TTL/CMOS Logic Integration, JTAG-ISP Reprogrammable Logic Cores.
PCI Bus Interface Logic
The EPM7160STI100-10's 10ns tPD speed grade is explicitly PCI Local Bus Specification Revision 2.2 compliant, making it ideal for implementing PCI target and bridge interfaces in 33 MHz PCI systems. Its 84 user I/Os accommodate the 32-bit multiplexed AD/C/BE bus plus PAR, FRAME#, IRDY#, TRDY#, STOP#, DEVSEL#, IDSEL, and PAR64 signals with room to spare for sideband controls. The 5.0V I/O tolerance directly matches classic PCI signaling levels without level shifters, and the 160 macrocells provide ample capacity for address decoding, command handling, and state-machine logic.
推薦
Microprocessor Peripheral Glue Logic
The EPM7160STI100-10 excels as a single-chip replacement for dozens of 74-series TTL/CMOS glue-logic packages in 5V microprocessor systems. The 160 macrocells and 84 user I/Os can implement address decoding, chip-select generation, wait-state insertion, bus arbitration, and interrupt prioritization in one device, dramatically simplifying PCB layout and reducing BOM cost. Its 10ns propagation delay ensures deterministic timing for fast 8051, x86, or 68k bus cycles without metastability, and EEPROM-based in-system programmability allows last-minute logic changes via JTAG without re-spinning the PCB.
推薦
Industrial Automation State Machines
The EPM7160STI100-10's industrial -40C to +85C temperature range (denoted by the I suffix) makes it well-suited for factory-floor controllers, PLC I/O expansion modules, and motor-control glue logic. Its deterministic 10ns timing ensures reliable state-machine transitions in safety-critical sequencing logic, while the 160 macrocells allow multi-axis stepper/servo control state machines to coexist with fieldbus interface logic (e.g., Modbus, Profibus, CAN). The 5V I/O interfaces directly with industrial 24V-sensed opto-isolated inputs via pull-ups, eliminating level translators.
推薦
Bus Arbitration and Address Decoding
For multi-master bus architectures such as VME, ISA, Multibus, or custom backplanes, the EPM7160STI100-10 provides dedicated bus arbitration logic with deterministic timing. Its 84 user I/Os comfortably handle 32-bit address plus 32-bit data plus arbitration control signals (BUSREQ, BUSGRANT, BUSACK) for multiple masters. The EEPROM non-volatile storage means configuration is retained across power cycles with no boot delay, critical for instant-on industrial systems. 160 macrocells are sufficient to implement priority encoders, address-decoder PLAs, and DMA handshake controllers in a single chip.
推薦
Legacy 5V TTL/CMOS Logic Integration
The EPM7160STI100-10's 5.0V core and 5.0V-tolerant I/Os make it a direct replacement for legacy 74LS, 74HC, 74F, 74AS, and 4000-series CMOS logic boards that cannot easily migrate to 3.3V. With 160 macrocells equating to roughly 400-500 discrete gates, one CPLD can replace an entire logic cage of TTL packages while reducing power consumption and board area. Its deterministic 10ns delay eliminates the timing skew problems of discrete TTL cascades, and JTAG-ISP allows board-level logic changes for prototypes without reworking components.
推薦
JTAG-ISP Reprogrammable Logic Cores
The EPM7160STI100-10's built-in IEEE 1149.1 JTAG interface and in-system programmability (ISP) enable field-upgradable logic without removing the device from the board. With 160 macrocells, designers can implement modular logic cores that are reconfigured via JTAG for firmware updates, design revisions, or feature enablement in production. This is particularly valuable for telecom infrastructure, military systems, and aerospace applications where board-level rework is impractical. The EEPROM cells support thousands of program/erase cycles, supporting in-field updates over the product lifetime.

設計說明
The EPM7160STI100-10 requires a stable 5.0 V supply on both VCCINT (core) and VCCIO (I/O) rails. Decoupling must include a 0.1 uF ceramic capacitor on each VCCINT/VCCIO pin placed within 5 mm of the pin, plus a 10 uF tantalum or aluminum polymer bulk capacitor at the regulator output. Power sequencing is not required between VCCINT and VCCIO, but the supply must rise monotonically from 0 V to 5 V to ensure proper EEPROM initialization. Estimated: total core current is approximately 200-400 mA at 100 MHz with all I/O toggling; verify with actual design activity factor.
The TQFP-100 package has 0.5 mm lead pitch requiring careful PCB layout. Use 0.2 mm trace width with 0.2 mm spacing between pads, and place a continuous ground plane on layer 2 to provide controlled impedance for high-speed signals. Route JTAG signals (TCK, TMS, TDI, TDO) with series 33 ohm termination resistors at the driver to suppress ringing; TCK in particular must be kept short to avoid clock distortion. Place decoupling capacitors on the same layer as the CPLD, never buried, to minimize loop inductance.
Do not attempt to use the EPM7160STI100-10 in 3.3V-only systems; both VCCINT and VCCIO require 5V supply per the MAX 7000 datasheet. Exceeding the absolute maximum VCC of 7V will permanently damage the device. Do not leave unused I/O pins floating; configure them as outputs driving low or as inputs with internal pull-ups enabled in the Quartus pin assignment. When programming via JTAG, ensure the JTAG chain does not include devices that interfere with the instruction register; chain ordering matters for ISP.
The 100 MHz internal frequency translates to roughly 10 ns edge rates on I/O pins, which generates significant harmonic content. For clock outputs or high-speed bus interfaces, consider series damping resistors (22-33 ohm) at the CPLD output to control overshoot and ringing on the PCB trace. For long traces (>50 mm), use controlled-impedance routing (50 ohm microstrip) and ensure the far-end termination matches. The 5V CMOS outputs have typical drive strength of 4-8 mA per pin - sufficient for short traces but marginal for long backplane connections; use buffers for long traces.
合規資訊
RoHS, REACH, lead-free, halogen-free, and conflict-minerals compliance information was not explicitly stated in the provided verified web data. The 'I' suffix denotes industrial temperature grade, and the 'N' suffix variant (EPM7160STI100-10N) is lead-free / RoHS-compliant. The base EPM7160STI100-10 (without N suffix) uses leaded solder finish. AEC-Q100 is not applicable because this is a programmable logic device, not an automotive-grade IC.
