3.3V Wide-Range General Purpose Inline I/O Pad Set
The 3.3V General Purpose I/O library provides bidirectional I/O,
isolated analog I/O, and a full complement of power cells along with
corner and spacer cells to assemble a complete pad ring by abutment.
An included rail splitter allows multiple power domains to be isolated
in the same pad ring while maintaining continuous VDD/VSS for
robust ESD protection.
▪ Programmable bidirectional GPIO
▪ Input-only buffer
▪ Isolated analog I/O
▪ Full complement of power, corner, and spacer cells

Features
- Bidirectional GPIO Driver Features
- ▪ Multi-Voltage (1.2V, 1.8V, 2.5V, 3.3V)
- ▪ LVCMOS / LVTTL input with selectable hysteresis
- ▪ Programmable drive strength (rated 2mA to 12mA)
- ▪ Selectable output slew rate
- ▪ Optimized for EMC with SSO factor of 8
- ▪ Open-drain output mode
- ▪ Programmable input options (pull-up/pull-down/repeater)
- ▪ Power-On Start (POS) capable
- ▪ Power sequencing independent design with Power-On Control
- In full-drive mode, this driver can operate to frequencies in excess of
- 100MHz with 15pF external load and 125 MHz with 10pF load.
- Actual frequency limits are load and system dependent. A maximum
- of 200 MHz can be achieved under small capacitive loads.
