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_CCA

while the B port is designed to track V_CCB0and V_CCB1. V_CCA,V_CCB0and V_CCB1can accept any supply voltage

from 1.4 V to 3.6 V.

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_CCB0and V_CCB1are switched off (no card inserted), the A-port outputs

are placed in the high-impedance state to conserve power.

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.
