General Description
The MAX3420E contains the digital logic and analog
circuitry necessary to implement a full-speed USB
peripheral compliant to USB specification rev 2.0. A
built-in full-speed transceiver features ±15kV ESD pro-
tection and programmable USB connect and discon-
nect. An internal serial-interface engine (SIE) handles
low-level USB protocol details such as error checking
and bus retries. The MAX3420E operates using a regis-
ter set accessed by an SPI interface that operates up
to 26MHz. Any SPI master (microprocessor, ASIC, DSP,
etc.) can add USB functionality using the simple 3- or
4-wire SPI interface.
Internal level translators allow the SPI interface to run at
a system voltage between 1.71V and 3.6V. USB timed
operations are done inside the MAX3420E with inter-
rupts provided at completion so an SPI master does not
need timers to meet USB timing requirements. The
MAX3420E includes four general-purpose inputs and
outputs so any microprocessor that uses I/O pins to
implement the SPI interface can reclaim the I/O pins
and gain additional ones.
The MAX3420E operates over the extended -40°C to
+85°C temperature range and is available in a 32-pin
LQFP package (7mm x 7mm) and a space-saving 24-
pin TQFN package (4mm x 4mm).
