ABSTRACT:
A technique and circuitry for interfacing an integrated circuit manufactured using technology compatible with one voltage level to other integrated circuits compatible with a different voltage level. In particular, the integrated circuit is fabricated using technology compatible with an internal supply voltage level. Externally, the integrated circuit will interface with an external supply voltage level, above the internal supply voltage. The input and output signals to and from the integrated circuit will be compatible with the external supply level. The integrated circuit may include a voltage down converter (1330) and level shifter (1317).
