Intersil’s New Logic Level Translators Deliver Dynamic Voltage Shifting in Mixed Supply Systems, Featuring Industry’s Most Robust ESD Protection on All Pins, in Compact, Stress-Resistant Packages
100 Megabit/second data rate supports high-speed SD memory cards
MILPITAS, CA, May 26, 2009 – Intersil Corporation
(NASDAQ Global Select: ISIL), a world leader in the design and manufacture
of high-performance analog and mixed signal semiconductors, today introduced
a new series of voltage logic level translators (VLTs) featuring industry-leading
ESD protection and 100 Megabit/second data rates for translating fast data
streams.
The new ISL3034E and ISL3035E are
six-channel, auto-direction sensing, bidirectional voltage level translators
that ease the interface between mixed supply voltage peripherals and controllers.
They are ideal for 3.3V SD, mini SD, memory stick and multimedia card applications
that require I/O signal translation to the industry’s latest low-voltage
system controllers. The ISL3036E delivers the same industry-leading
performance in a four-channel configuration.
With IEC61000-4-2 +/-15kV Air Gap, +/-9kV contact, and +/-15kV HBM protection
on all input, output and I/O lines, these new translators provide the industry’s
best ESD protection. This is especially important in SD memory card applications,
where the translator resides at the edge of the connector and can be vulnerable
to ESD events.
The ISL3034E/35E/36E series features auto-direction sensing, eliminating the
need for direction control logic pins and associated software control, making
them excellent design choices for memory-card level translation or for general-purpose
applications. In addition the auto-direction sensing function allows bit-by-bit
determination of signal flow.
The new voltage level translator (VLTs) operate with VCC (SD
card supply) voltages from +2.2V to +3.6V and VL voltages
from +1.35V to +3.2V, enabling data transfer between low-voltage MCUs or ASICs
and higher voltage components, such as SD cards. These power supply ranges
allow level shifting between 1.5V, 1.8V, and 2.5V powered devices on the VL (system
controller supply side) and 2.5V and 3.3V devices on the VCC side.
Each I/O channel is pulled up to VCC or VL by
an internal 30μA current source, allowing the VLTs to be driven by either
push-pull or open-drain drivers.
The ISL3034E and ISL3036E also
have an enable (EN) input that places the IC into a low-power shutdown mode
when the input is driven low. All versions feature an automatic shutdown
mode that places the part in the same low power state when VCC is
less than VL. The ISL3035E features a clock
return output that returns the same signal applied to the clock VL input,
but with a delay that better mimics the timing of data read back from a memory
card.
Packaging, Pricing and Availability
Each is now available in tiny 2.6 mm x 1.8 mm 16 leadless µTQFN packages,
which are superior to chip scale packages because they do not crack or break
under stress, and have improved pin access for easier debug and rework access.
Pricing starts at $0.79 each in 1,000-piece quantities for the ISL3034E and
ISL3035E; the ISL3036E is available at $0.71 each in 1,000-unit quantities.
