description/ordering information

The SN74AVCA406 is a transceiver for interfacing microprocessors with MultiMediaCards (MMCs), secure digital

(SD) cards, Memory Stick compliant products, SmartMedia cards, or xD-Picture Cards. It integrates high ESD

protection, which eliminates the need for external ESD diodes. Two supply-voltage pins allow the A-port and B-port

input switching thresholds to be configured separately. The A port is designed to track V

, while the B port is

CCA

designed to track V

and V

. V

and V

can accept any supply voltage from 1.4 V to 3.6 V.

CCB1

Memory card standards recommend high ESD protection for devices that connect directly to the external memory

card. To meet this need, the SN74AVCA406 incorporates 15-kV air gap discharge and 8-kV contact discharge

protection on the card side. If V

in the high-impedance state to conserve power.

and V

are switched off (no card inserted), the A-port outputs are placed

CCB1

The SN74AVCA406 enables system designers to easily interface low-voltage microprocessors to different memory

cards operating at higher voltages. The mode (MODE0 and MODE1) pins are used to configure the device to

interface with different types of cards.

The SN74AVCA406 is offered in the 48-ball MicroStar Jr. ball grid array (BGA) package. This package has

dimensions of 4 × 4 mm, with a 0.5-mm ball pitch for effective board-space savings. Memory cards are widely used

in mobile phones, PDAs, digital cameras, personal media players, camcorders, set-top boxes, etc. Low static power

consumption and small package size make the SN74AVCA406 an ideal choice for these applications.
