Replacement verdict
Compatible functional replacement candidate
The EPM570F100A5N is a functionally compatible alternative to the EPM570F100C5N, sharing the same logic density, package, and I/O configuration, with the primary distinction being the faster speed grade of the A5N variant. Both devices are suitable for direct substitution in most designs, provided timing margins are revalidated for the higher-performance grade.

Key electrical and mechanical differences between the two devices
| Parameter | EPM570F100C5N | EPM570F100A5N | Why it matters |
|---|---|---|---|
| Series | MAX II | MAX II | Both devices belong to the same MAX II CPLD family, so they share the same architecture and design tool support. |
| Logic Elements | 570 | 570 | Identical logic capacity means the same design fits in either device without resource changes. |
| Package / Pin Count | 100-pin FBGA | 100-pin FBGA | Same package and pin count allow a drop-in board-level replacement without layout changes. |
| Supply Voltage | 1.8 V core / 3.3 V I/O | 1.8 V core / 3.3 V I/O | Matching voltage requirements ensure the same power supply design can be reused. |
| Speed Grade | 5 | 5 | Speed grade determines maximum operating frequency; the "C" and "A" suffixes denote different temperature/qualification grades rather than speed. |
| Operating Temperature Range | Commercial (0°C to 85°C) | Industrial (-40°C to 85°C) | The industrial-grade version supports wider temperature extremes, which is critical for harsh-environment applications. |
| Configuration Memory | Flash-based (non-volatile) | Flash-based (non-volatile) | Non-volatile configuration means the device retains its design without external configuration memory. |
| User I/O Pins | 76 | 76 | Identical I/O count ensures the same number of external signals can be interfaced. |

Frequently asked questions
What are the key differences between the EPM570F100C5N and EPM570F100A5N?
The primary difference is the operating temperature range. The EPM570F100C5N is specified for commercial temperature range (0°C to 85°C), while the EPM570F100A5N is specified for industrial temperature range (-40°C to 85°C). Both are based on the same MAX II CPLD family, feature 570 logic elements, 100-pin FBGA package, and speed grade 5.
Are the EPM570F100C5N and EPM570F100A5N pin-to-pin compatible?
Yes. Both devices share the same 100-pin FineLine BGA (FBGA) package with identical pinouts, allowing for direct PCB layout compatibility when the temperature grade difference is acceptable for the application.
Can the EPM570F100C5N be used as a drop-in replacement for the EPM570F100A5N?
No, not in all cases. The EPM570F100C5N is rated only for commercial temperatures (0°C to 85°C), whereas the EPM570F100A5N supports industrial temperatures (-40°C to 85°C). Substitution is only valid if the target application operates strictly within the commercial temperature range and all other specifications are verified against the design requirements.
What is the logic capacity of the EPM570F100C5N and EPM570F100A5N?
Both devices provide 570 logic elements (LEs), 440 equivalent macrocells, and 8,192 bits of user flash memory, as defined by the Intel MAX II CPLD family specifications.
What speed grade do the EPM570F100C5N and EPM570F100A5N use?
Both devices are speed grade 5, which is the fastest standard speed grade offered for the MAX II EPM570 family. This speed grade designation is identical for both the commercial and industrial temperature versions.
What are the operating temperature ranges for the EPM570F100C5N and EPM570F100A5N?
The EPM570F100C5N operates over the commercial temperature range of 0°C to 85°C (junction temperature). The EPM570F100A5N operates over the industrial temperature range of -40°C to 85°C (junction temperature).
Do the EPM570F100C5N and EPM570F100A5N have the same power supply requirements?
Yes. Both devices require a core supply voltage (VCCINT) of 1.8 V and I/O supply voltages (VCCIO) that can be configured for 1.5 V, 1.8 V, 2.5 V, or 3.3 V, consistent with the MAX II CPLD family electrical specifications.
Which device is more suitable for industrial applications, the EPM570F100C5N or the EPM570F100A5N?
The EPM570F100A5N is more suitable for industrial applications because its -40°C to 85°C temperature range meets the requirements of industrial environments. The EPM570F100C5N is limited to commercial applications within 0°C to 85°C.
