R e v i sio n 1 1

1.2 V LVCMOS (JESD8-12A)

Low-Voltage CMOS for 1.2 V complies with the LVCMOS standard JESD8-12A for general purpose 1.2 V

applications. It uses a 1.2 V input buffer and a push-pull output buffer.

Notes:

1. Applicable to IGLOO nano V2 devices operating at VCCI

≥ VCC.

2. IIL is the input leakage current per I/O pin over recommended operation conditions where –0.3 V < VIN < VIL.

3. IIH is the input leakage current per I/O pin over recommended operating conditions VIH < VIN < VCCI. Input current is

larger when operating outside recommended ranges.

4. Currents are measured at high temperature (100°C junction temperature) and maximum voltage.

5. Currents are measured at 85°C junction temperature.

6. Software default selection highlighted in gray.
