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.
