ST6G3240

Dual supply level translator for dual memory cards

(mini SD/micro SD + managed NAND)

Features

■ High speed: t (A to B) = 5 ns at T = 85 °C

with V

= 1.8 V, V

= 3.0 V

CCA

CCBn

■ Low power dissipation: I

= I

= 5 µA

CCA

CCBn

(max.) at T = 85 °C

■ Balanced propagation delays: t_PLH≈ t

■ Operating voltage range:

PHL

– V

(opr) = 1.4 to 3.6 V

CCA

(opr) = 1.4 to 3.6 V

CCBn

■ B-side power supplies (V

and V

) can

CCB2

CCB1

be different and separately controlled

■ Interchangeable voltage levels:

μTFBGA 36

can either be greater than or less than

CCA

CCBn

■ Low power mode:

when V is grounded or floating, there is

CCBn

very low quiescent current on V

Description

CCA

■ Power down detection:

The ST6G3240 is a dual supply low voltage

CMOS level translator supporting the dual

function of mini SD/micro SD card and managed

NAND memories. It is designed for use as an

interface between three systems using 3.3, 2.5

and 1.8 V respectively.

when either one of the B-side power supplies

(V and V ) is grounded or floating, the

CCB1

CCB2

corresponding port-n goes into high-Z state

automatically

■ Latch-up performance exceeds 500 mA

(JESD17)

The ST6G3240 is capable of achieving high

speed operation and at the same time maintaining

low power dissipation.

■ ESD protection: 2 kV HBM

■ Integrated pull-up resistor and level translator

on the MS_Insert pin

While the A port is designed to track V

, the Bn

CCA

port (nCMD, nDAT, nCLK) is designed to track

■ Integrated pull-up resistor for card-detect pin

CCBn

The device is intended for a two-way

asynchronous communication between data

buses.
