Typical Applications
EPM7192SQI160-10 is suitable for 6 applications: Industrial Control Glue Logic, Bus Interface and Protocol Bridging, Power-Up Sequencing State Machine, Legacy System Replacement, Instrumentation Front-End Control, Telecom and Networking Line Cards.
Industrial Control Glue Logic
The EPM7192SQI160-10 fits industrial control glue logic because its 192 macrocells and 124 user I/Os consolidate discrete 74-series logic into one deterministic device, and its -40 C to +85 C industrial rating covers factory-floor temperature extremes. The 7.5 ns pin-to-pin delay and fixed PIA routing give predictable timing for interlock and handshake paths, unlike FPGA fabric where routing affects delay. It is typically placed between a microcontroller bus and motor-driver or relay interfaces, decoding chip selects and generating strobes. The trade-off is 5.0 V supply and higher static power versus modern 3.3 V CPLDs, but it removes level shifters when interfacing legacy industrial TTL peripherals.
Recommended
Bus Interface and Protocol Bridging
The EPM7192SQI160-10 suits bus bridging because 124 user I/Os can implement wide address/data paths between dissimilar buses, such as ISA-to-peripheral or custom parallel-to-serial conversion. Its 167 MHz internal counter frequency supports clocked state machines that oversample slower buses, while EEPROM configuration means the bridge is active immediately at power-up with no FPGA configuration PROM. Designers typically use it to translate between a host processor bus and legacy peripherals, generating wait states and handshake signals in programmable logic. The 160-pin QFP provides enough pins for a 16-bit data bus plus control, though the 5.0 V I/O requires care when the host runs at 3.3 V.
Recommended
Power-Up Sequencing State Machine
The EPM7192SQI160-10 is well suited to power-up sequencing because EEPROM-based MAX 7000S logic is live within microseconds of VCC crossing threshold, with no configuration load from an external device. A 192-macrocell array can implement multi-rail enable sequencing, fault latching, and watchdog timers for processors and analog rails. The 7.5 ns propagation delay ensures enable signals assert in the intended order even at fast ramp rates, and the non-volatile configuration survives power cycling without a battery. It is typically placed on the always-on rail, driving regulator EN pins and reset lines. The main consideration is that sequencing logic must be validated across the full industrial temperature range.
Recommended
Legacy System Replacement
The EPM7192SQI160-10 is frequently used to replace obsolete discrete logic and PAL/GAL devices in legacy systems, because its 192 macrocells absorb dozens of small logic ICs into one 160-pin QFP while preserving 5.0 V TTL/CMOS compatibility. Engineers reverse-engineer old glue logic into MAX+PLUS II or Quartus designs, then fit the EPM7192S to the existing footprint. The industrial temperature grade matches the original equipment's environmental spec, and EEPROM retention avoids adding a configuration device to a board that never had one. The trade-off is that the MAX 7000S family itself is now obsolete, so replacement builds depend on broker stock or a planned migration to MAX II/V.
Recommended
Instrumentation Front-End Control
The EPM7192SQI160-10 fits instrumentation front-end control because it can implement ADC/DAC interface timing, multiplexer channel selection, and trigger generation in deterministic logic. The 124 user I/Os drive parallel-interface converters and range relays, while the 167 MHz internal frequency supports fast sample-clock generation and pulse timing. Fixed PIA routing gives repeatable trigger latency, which matters for measurement repeatability. It is typically placed between the analog front end and a host processor, handling real-time control while the processor manages data. The 5.0 V I/O matches many industrial converters, but designers must budget for the higher quiescent power of the MAX 7000S architecture.
Recommended
Telecom and Networking Line Cards
The EPM7192SQI160-10 suits telecom and networking line cards because it provides deterministic glue logic for TDM framing, clock selection, and backplane interface control. The 192 macrocells implement channel-associated state machines and status registers, while 124 I/Os handle parallel control buses and LED/status outputs. EEPROM configuration ensures the card's control logic is active before the host processor boots, which is important for hot-swap and redundancy sequencing. The industrial temperature range covers central-office and outdoor-cabinet environments. Designers should note that the 5.0 V supply is uncommon on modern line cards, so level translation may be required for 3.3 V backplanes.

- Non-volatile EEPROM configuration (vs EPM7192SQC160-10N)
- Balanced speed grade for deterministic control (vs EPM7192SQC160-7N)
Design Notes
The MAX 7000S is a 5.0 V EEPROM-based CPLD and draws significantly more quiescent current than modern 3.3 V or 1.8 V CPLDs. Decouple every VCC pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus at least one 10 uF bulk capacitor per device. Estimated: at 5.0 V and typical ICC of a few tens of mA, the device dissipates well under 1 W, but confirm the exact ICC from the Altera MAX 7000 datasheet for your toggle rate before finalizing the thermal budget.
Route the 160-pin QFP with a solid ground plane directly under the device and keep high-speed I/O traces short and matched where they form buses. Because the MAX 7000S uses a fixed programmable interconnect array, timing is largely routing-independent, but board-level crosstalk between adjacent I/O still matters. Place series termination resistors (22-33 ohm) on fast outputs that drive long traces, and keep the ISP programming header (TCK, TMS, TDI, TDO) close to the device with short stubs.
The EPM7192SQI160-10 is obsolete, so do not design it into new production without a documented last-time-buy or migration plan to MAX II/MAX V. When substituting EPM7192SQC160-10 for the industrial SQI part, verify the target environment stays within 0 C to +70 C. Also confirm the JTAG ISP chain: MAX 7000S devices are programmed in-system at 5.0 V, and mixing them with 3.3 V JTAG devices requires level-compatible programming hardware.
Compliance Information
Compliance data was not present in the verified web data for EPM7192SQI160-10. The lead-free variant is EPM7192SQC160-10N (N suffix). Confirm RoHS/REACH status with the distributor before design release.
