The EP3C5E144C8N
Altera Cyclone III FPGA has a core voltage supply range of 1.15V to 1.25V. The I/O pins can operate at different voltage levels depending on the I/O standard used, but a common I/O voltage is 3.3V, according to some online resources.
Here's a more detailed breakdown:
- Core Voltage:
The internal logic of the EP3C5E144C8N operates at a voltage range of 1.15V to 1.25V.
- I/O Voltage:
The I/O pins can be configured to support different voltage levels based on the chosen I/O standard (e.g., LVTTL, LVCMOS, etc.).
- Common I/O Voltage:
A common I/O voltage for this device is 3.3V, but it can be different depending on the specific application and the chosen I/O standard.
- Examples of I/O Standards and Voltages:
- LVTTL: Typically uses 3.3V or 2.5V.
- LVCMOS: Can support various voltage levels, including 3.3V, 2.5V, 1.8V, and 1.5V.
- HSTL, SSTL: Used for higher speed interfaces and typically operate at 1.5V or 1.8V.
