    Abstract: An input/output circuit layout has a first section in which first transistors having a thicker gate oxide are located and a second section in which second transistors having a thinner gate oxide are located. Due to process technology constraints, the gates of all of the second transistors are oriented in a single common direction. The second section has a perimeter having a square shape including a first edge and a second edge adjacent to the first edge. First connection pins coupled to the second transistors are provided with an orientation that extends inwardly from and perpendicular to the first edge. Second connection pins coupled to the second transistors are provided with an orientation that extends inwardly from and perpendicular to said second edge. The square shape and presence of pins on adjacent first and second edges permits rotation of the second section to fit within different orientations of the layout.

    Abstract: A serial peripheral interface (SPI) device includes a serial clock (SCK) pad receiving a serial clock, first and second Schmitt triggers directly electrically connected to the SCK pad to selectively respectively generate first and second clocks in response to rising and falling edges of the serial clock, first and second flip flops clocked by the first and second clocks to output bits of data to a data node, a multiplexer having an input coupled to the data node and an output coupled to driving circuitry, and driving circuitry transmitting data via a master-in-slave-out (MISO) pad.

    Abstract: An input signal having a logic low level at a first voltage and a logic high level at a second voltage is received by a Schmitt trigger. A voltage generator outputs a reference voltage generated from a third voltage that is higher than the second voltage. A first transistor coupled between the third voltage and a power supply node of the Schmitt trigger is biased by the reference voltage to apply a fourth voltage to the power supply node of the Schmitt trigger that is dependent on the reference voltage. The reference voltage has a value which causes the fourth voltage to be less than or equal to the second voltage. A second transistor coupled between the input signal and the input of the Schmitt trigger circuit is also biased by the reference voltage to control the logic high level voltage of the input signal at the Schmitt trigger.
