A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on characteristics of PAL/GAL architectures with the high integration density of FPGAs. Within the broader taxonomy, a CPLD is a sub-category of programmable logic devices (PLDs), sitting above discrete 22V10 GALs in density and below modern low-power FPGAs. The MAX 7000S family sits in Altera's classic mid-density CPLD portfolio and is widely used as the 'glue logic' layer between processors, memories, and peripherals in 5V-tolerant systems.
Key differentiating features include a 5.0V core and I/O supply, 3.3V or 5V multi-voltage JTAG-based in-system programmability, 100 MHz internal performance, support for up to 84 user I/Os (some sources cite 104 I/Os for the TQFP-100 variant), and an industrial operating temperature range of -40C to +85C indicated by the 'I' suffix. The 'I' designator additionally implies lead-free assembly, an important differentiator versus the older non-I commercial variant.
Architecturally, the EPM7160S pairs EEPROM configuration cells with a Logic Array Block (LAB) interconnect fabric, with macrocells combining programmable AND/OR arrays with configurable flip-flops. The MAX 7000S device supports JTAG-compliant IEEE 1149.1 boundary-scan testing, four user I/O pinout schemes via dedicated pin compatibility with other MAX 7000S density points, and a high-performance input path with a global clock network.
Typical applications include address decoding and bus interface bridging in 5V microprocessor systems, peripheral glue-logic replacement for legacy 74-series TTL/CMOS logic, industrial control and instrumentation I/O expansion, power-supply sequencing logic, and JTAG-controlled in-system programmable front-ends. Designers frequently choose the EPM7160STI100-10N as a drop-in for end-of-life 22V10 and similar discrete PLD footprints.
When designing with this part, pay particular attention to the 5.0V VCC requirement - the S-suffix variant uses 3.3V core, while the EPM7160S family generally operates at 5V - and ensure the JTAG chain respects IEEE 1149.1 ordering when multiple devices share the same boundary-scan test access port.

Ứng dụng tiêu biểu
EPM7160STI100-10N phù hợp cho 6 Áp dụngs: Microprocessor Address Decoding, Bus Interface Bridging, Legacy TTL/CMOS Glue Logic Replacement, Industrial Control I/O Expansion, Power Supply Sequencing & Control Logic, JTAG-Based Boundary-Scan Test Front-End.
Microprocessor Address Decoding
The EPM7160STI100-10N is widely used as a high-density address decoder for 5V microprocessor and microcontroller systems, replacing banks of 74LS138 / 74HC138 decoder ICs with a single programmable device. With 160 macrocells and 84 user I/Os in TQFP-100, the part can decode large memory and peripheral address spaces (e.g., 24-bit or 32-bit CPU buses) and generate chip-select signals with predictable 10 ns timing. The non-volatile EEPROM configuration means the decoder starts operating on power-up with no bootloader latency, critical for deterministic system bring-up. Designers benefit from JTAG-based in-system reprogrammability, allowing address-map changes without board rework.

Bus Interface Bridging
The EPM7160STI100-10N bridges mismatched bus protocols in mixed-voltage 5V/3.3V systems, such as ISA-to-PCI, memory-to-ASIC, or legacy-MCU-to-modern-FPGA interfaces. The MAX 7000S family's multi-voltage ISP support (3.3V and 5V JTAG) and 5.0V VCC tolerance make it ideal for level-shifting and protocol-conversion glue logic. With 10 ns pin-to-pin delay and 100 MHz internal frequency, the device can sustain high-throughput data paths while still fitting in the TQFP-100 footprint used on thousands of legacy designs. In-system programming via the IEEE 1149.1 JTAG chain enables field firmware updates without removing the part from the board.

Legacy TTL/CMOS Glue Logic Replacement
The EPM7160STI100-10N is frequently deployed to consolidate scattered 74-series TTL/CMOS glue logic - latches, multiplexers, parity generators, and shifters - into a single reprogrammable device. With 3,200 usable gates and 160 macrocells, one EPM7160S can replace 10-20 discrete MSI logic ICs, reducing PCB area, BOM cost, and supply-chain risk for obsolete 74LS/74F parts. The industrial -40C to +85C temperature range enables deployment in factory-automation and outdoor-instrumentation enclosures. Designers port existing discrete-logic schematics directly into Altera's MAX+PLUS II or Quartus II HDL, preserving proven timing behavior with the 10 ns tPD budget.
Được đề xuất
Industrial Control I/O Expansion
The EPM7160STI100-10N provides deterministic, low-latency I/O expansion for PLCs, motor controllers, and industrial sensor interfaces where software-driven GPIO on a microcontroller is too slow or non-deterministic. With 84 user I/Os and 10 ns tPD, the CPLD can debounce mechanical switches, generate PWM outputs for motor-drive logic, and implement safety interlocks in parallel with the main CPU. The MAX 7000S family EEPROM-based non-volatile storage ensures the I/O map configuration survives power cycles without firmware reload. Industrial-temperature grade (-40C to +85C) and lead-free assembly suit harsh-environment deployments.

Power Supply Sequencing & Control Logic
The EPM7160STI100-10N is used as a multi-rail power-supply sequencer in 5V industrial and telecom systems where FPGA, ASIC, and DSP cores require strict power-up and power-down ordering. Each of the 160 macrocells can implement a comparator-based rail-good detector combined with adjustable delay timers, generating precision enable signals for downstream DC-DC converters. The non-volatile EEPROM configuration means sequencing starts immediately at power-up without MCU intervention, and JTAG-based in-system programming allows last-minute sequencing changes during board bring-up. The TQFP-100 footprint integrates easily beneath or beside the power-tree ICs on standard 4-layer PCBs.
Được đề xuất
JTAG-Based Boundary-Scan Test Front-End
The EPM7160STI100-10N supports IEEE 1149.1 JTAG boundary-scan and can be configured as a multi-device JTAG chain master or as a built-in self-test (BIST) controller on manufacturing test fixtures. With 84 user I/Os, the part can fan out TAP signals to multiple downstream clusters and aggregate pass/fail status. The 5.0V ISP-compatible JTAG interface simplifies in-system programming during board bring-up and field upgrades. Manufacturing-test engineers use the CPLD's deterministic 10 ns timing to capture at-speed functional vectors, reducing test-time versus software-driven boundary-scan alone.

Ghi chú thiết kế
The EPM7160STI100-10N requires a monotonic 5.0V VCC ramp at power-up; voltage droop or non-monotonic rise can cause EEPROM configuration mis-reads. Decouple VCC with one 100 nF ceramic cap per VCC pin (4 caps on TQFP-100) plus a single 10 uF bulk tantalum or ceramic cap within 25 mm of the device. Hold all I/O inputs at valid logic levels until VCC stabilizes to avoid spurious EEPROM writes. Estimated quiescent current is approximately 10-30 mA standby plus macrocell-dependent dynamic current, so size upstream regulators with adequate headroom.
Route the JTAG chain (TDI/TDO/TMS/TCK) with 50-ohm controlled impedance and avoid stubs longer than 10 mm. Place the CPLD within 50 mm of the JTAG header to minimize reflections at TCK frequencies above 10 MHz. Provide a pull-up resistor (typically 4.7 kohm) on each JTAG signal if multiple devices share the chain, and add series ferrite beads if the board is in a noisy industrial environment. The TQFP-100 exposed pad (if present on the specific variant) should be soldered to a thermally grounded copper pour to reduce junction temperature.
Do not confuse the EPM7160STI100-10N with the EPM7160STC100-10N - the I-suffix indicates industrial temperature grade (-40C to +85C) while C-suffix is commercial (0C to +70C). Mixing them up in a BOM for outdoor industrial equipment will lead to field failures. The 'N' suffix indicates lead-free (Pb-free) assembly; non-N variants use lead-bearing solder and may not be RoHS-compliant. Confirm both 'I' and 'N' markers in the part number before placing volume orders, especially for end-customer applications requiring RoHS and industrial temperature concurrently.
Thông tin tuân thủ
RoHS compliance inferred from 'N' suffix (lead-free) and 'I' industrial marking on datasheet. Halogen-free status and conflict-mineral declarations not stated in available distributor listings. AEC-Q100 not applicable - this is a programmable logic device, not an automotive-grade IC, but Altera MAX 7000S family has been used in industrial and some non-safety-critical automotive applications.
