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_CCB0 and V_CCB1. V_CCA ,V_CCB0 and V_CCB1 can 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_CCB0 and V_CCB1 are 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.
