General Purpose I/O (GPIO) in TSMC(12nm,16nm,22nm, 28nm, 40nm, 90nm BCD+, 152nm BCD, 180nm BCD)
- Basic input/output unit for a chip with digital core
- Consisting of driver, receiver & pull-up/down resistors
- According to PAD arrangement, classified into two groups: Inline I/O & Stagger one.
- M31 also develops fail-safe or tolerance I/O for special application. The leakage current is inhibited when I/O power ramp down (Diagram A).
