MAX14850PMB1 Peripheral Module
General Description
The MAX14850PMB1 peripheral module utilizes the
MAX14850 digital isolator to isolate another SPI- or UART-
based module from any host system that utilizes Pmod^K-
compatible expansion ports configurable for either a UART
or SPI interface. This peripheral module is first plugged
into the host Pmod port. Another UART- or SPI-based
module plugged into the 12-pin Pmod-compatible
connector on this peripheral module is galvanically isolated
from the host and referenced to a secondary power supply
connected to this peripheral module.
The IC is a 6-channel digital isolator utilizing Maxim’s pro-
prietary process technology, whose monolithic design
provides a compact and low-cost transfer of digital
signals between circuits with different power domains. Of
the six total channels, the four unidirectional channels are
each capable of DC to 50Mbps, with two of the four chan-
nels passing data across the isolation barrier in each
direction. The two bidirectional channels are open drain
and each is capable of data rates from DC to 2Mbps.
Refer to the MAX14850 IC data sheet for detailed informa-
tion regarding operation of the IC.
