M31 provides a silicon-proven GPIO library in different process nodes. The GPIO solutions are also available at 180BCD, 152BCD, 90BCD, 110HV, 55nm and 28nm technology process.
- Basic input/output unit for a chip with digital core
- Consisting of driver, receiver & pull-up/down resistors
- Usually speed < 100Mhz
- According to PAD arrangement, classified into two groups: Inline I/O & Stagger one. The former one is usually used for core-limit IC and the latter for pad-limit
- Available in 180BCD, 152BCD, 90BCD, 110HV, 55nm and 28nm process nodes
