Safe Operating Area (SOA) & Thermal Characteristics

Typical Applications
EPM7160STC100-10N is suitable for 6 applications: PCI Bus Interface Bridge, Address Decoding & Chip-Select Logic, Legacy Industrial Control Board, Peripheral Adapter / Glue Logic Replacement, Mixed-Voltage System Controller, Embedded Bus Master & Protocol Converter.
PCI Bus Interface Bridge
The EPM7160STC100-10N is well-suited for PCI bus interface bridging thanks to its 10 ns tPD and 66 MHz PCI compliance. The MAX 7000S architecture provides deterministic pin-to-pin timing, which is essential for the setup/hold requirements of the 33 MHz and 66 MHz PCI specification. Place the CPLD between a host processor and a downstream PCI device to decode command/address signals, generate chip-selects, and arbitrate bus tenure. With 84 user I/Os, multiple PCI signals can be buffered and re-driven in a single device, replacing dozens of discrete 74-series glue-logic chips. Note that input signals must satisfy the PCI 5 V/3.3 V signaling levels using the MultiVolt I/O feature, with VCCIO tied to the matching supply rail.
Recommended
Address Decoding & Chip-Select Logic
The EPM7160STC100-10N excels at address decoding and chip-select generation in memory-mapped systems. With 160 macrocells and 10 ns tPD, it can decode wide address buses (24-32 bits) and generate multiple chip-select signals in a single pass without violating processor access-time budgets. Typical use: decode the upper address bits of an ARM, x86, or MIPS host to enable peripherals, SRAM, Flash, or FPGA registers. Compared to a discrete 74HC138/139 decoder cascade, the CPLD offers reconfigurability, fewer PCB traces, and lower BOM cost at moderate volumes. MultiVolt I/O lets one device decode 5 V host buses while driving 3.3 V peripherals, eliminating level-shifters.
Recommended
Legacy Industrial Control Board
The EPM7160STC100-10N's MAX 7000S heritage and 5 V supply make it a popular choice in legacy industrial control boards with long service-life requirements (10-20 years). The non-volatile EEPROM configuration means the board boots into a known state without an external configuration PROM - critical for factory automation where power-cycle resilience matters. The commercial 0C to 70C temperature grade suits indoor cabinet installations, while the 84 user I/Os aggregate multiple discrete control signals (limit switches, relay drivers, encoder inputs). For outdoor or harsh environments, consider the industrial-temperature sibling EPM7160STI100-7 in the same TQFP-100 footprint.
Recommended
Peripheral Adapter / Glue Logic Replacement
The EPM7160STC100-10N can replace 5-15 discrete 74-series TTL/CMOS glue-logic chips (latches, buffers, transceivers, muxes, parity generators) with a single programmable device, dramatically reducing PCB area and BOM count. The 10 ns tPD is fast enough for most peripheral-adapter timing, including ISA bus interfacing, UART glue, parallel-port adapters, and SCSI termination logic. The JTAG ISP allows late-stage design changes: firmware engineers can revise the logic weeks after PCB fab without re-spinning the board. Use the Quartus MAX+PLUS II design tools to capture the logic via schematic or VHDL/Verilog HDL, then download the JEDEC file via JTAG.
Recommended
Mixed-Voltage System Controller
The EPM7160STC100-10N's MultiVolt I/O architecture makes it ideal for bridging 5 V legacy subsystems and 3.3 V modern peripherals on the same board. With VCCINT at 5 V and VCCIO programmable to 3.3 V, the device can drive 3.3 V logic while receiving 5 V TTL inputs directly (the inputs are 5 V tolerant when VCCIO is at 3.3 V). Common use cases: bridge an embedded 5 V microcontroller bus to a 3.3 V FPGA fabric, or interface legacy ISA cards to a modern 3.3 V PCI-104 stack. The 84 user I/Os can serve multiple voltage domains simultaneously when I/O banks are powered independently.
Recommended
Embedded Bus Master & Protocol Converter
The EPM7160STC100-10N can act as a deterministic bus master and protocol converter between heterogeneous interfaces - for example, converting between I2C and parallel buses, generating SPI chip-select sequences from a CPU GPIO, or implementing a custom backplane protocol. The 160 macrocells support a deep state machine plus parallel datapath logic, while the 84 I/Os allow up to 4-6 concurrent buses to be multiplexed. Designers can iterate the protocol logic in software (Quartus MAX+PLUS II) without respinning the board, accelerating prototype-to-production. The EEPROM configuration boots instantly at power-up, so no host boot sequence is required to bring the bus online.

Key Differentiators
- 100% pin-compatible with EPM7160STC100-10 (no 'N') on same TQFP-100 footprint (vs EPM7160STC100-10)
- Same TQFP-100 footprint as industrial-temperature EPM7160STI100-7 with 25% faster timing (vs EPM7160STI100-7)
- Smaller MAX 7000S option (128 macrocells) available in same TQFP-100 footprint (vs EPM7128STC100-10N)
Design Notes
The EPM7160STC100-10N requires two supplies: VCCINT (4.75-5.25 V) for the core logic and VCCIO (3.0-5.25 V) for the I/O bank drivers. Place a 0.1 uF ceramic decoupling capacitor as close as possible to every VCCINT and VCCIO pin, with a bulk 10-100 uF tantalum or aluminum polymer capacitor at the supply rail entry. The MultiVolt feature allows VCCIO to be lower than VCCINT; however, when VCCIO is below 3.0 V, a slightly greater timing delay (tOD2 instead of tOD1) applies per the MAX 7000S datasheet. Power sequencing: VCCINT must rise monotonically from 0 V to its final value without droops or negative transients, or the EEPROM configuration may not load reliably.
The TQFP-100 package has a 0.5 mm lead pitch, requiring fine-pitch PCB assembly capability. Use a 4-layer or better stack-up with a solid ground plane directly under the device to provide a low-impedance return path for switching I/O currents. Route JTAG signals (TMS, TCK, TDI, TDO) as a dedicated test bus with no stubs; add a 10 kohm pull-up on TCK and TMS to ensure a defined state during power-up. Place a JTAG header or test-point cluster on the board for in-system programming and boundary-scan debug. Avoid running high-speed signals under the TQFP-100 footprint to prevent crosstalk into the device's internal logic.
Estimated: at 5.0 V VCCINT, 100 MHz internal frequency, and ~30 mA typical ICC, the EPM7160STC100-10N dissipates approximately 0.15 W. However, with all 84 I/Os switching simultaneously at 5 V into 30 pF loads at 50 MHz, dynamic power can reach 0.5 W or more. Do not exceed the absolute maximum DC input voltage of -0.5 V to +7.0 V on any I/O pin. During transitions, undershoot to -2.0 V is tolerated only for input currents below 100 mA and pulses shorter than 20 ns. Mixing 3.3 V and 5 V peripherals on different I/O banks requires separate VCCIO rails per bank; verify your PCB supplies the correct voltage to each bank before applying power.
Compliance Information
Compliance status not explicitly stated in the verified web data; the 'N' suffix on the part number may denote a specific lead-free/RoHS finish per industry convention but this was not confirmed. Parts in the EPM7160S family typically ship in both lead and lead-free variants. AEC-Q100 not applicable (industrial/legacy part).
