C UART with 128-Word FIFOs in WLP
General Description
The MAX3108 small form factor universal asynchronous
receiver-transmitter (UART) with 128 words each of
receive and transmit FIFOs is controlled through a serial
I
2
C or SPI™ controller interface. Auto-sleep and shut-
down modes help reduce power consumption during
periods of inactivity. A low 500FA (max) supply current
and tiny 25-bump WLP (2.1mm x 2.1mm) package make
the MAX3108 ideal for low-power portable devices. The
MAX3108 operates from a supply voltage of 1.71V to 3.6V.
Baud rates up to 24Mbps make the MAX3108 suitable for
today’s high data rate applications. A phase-locked loop
(PLL), predivider, and fractional baud-rate generator allow
high-resolution baud-rate programming and minimize the
dependency of baud rate on reference clock frequency.
Four GPIOs can be used as inputs, outputs, or interrupt inputs.
When configured as outputs, they can be programmed to be
open-drain outputs and sink up to 20mA of current.
The MAX3108 is ideal for portable and handheld devic-
es, is available in a 25-bump (2.1mm x 2.1mm) 0.4mm
pitch WLP package, and is specified over the -40NC to
+85NC extended temperature range.
