with an M12 circular housing and avoid the high cost of custom light pipes.This is
the reason why the MAX44008 is placed on an extremely small half moon shaped board that is then soldered onto the tip of the
Santa Cruz board as shown in Figure 2.
An ultra-low-power RL78/G1A microcontroller with current consumption down to 66µA/MHz provides system control on Santa
Cruz. It features 64KB on-chip programmable flash memory, 4KB on-chip data flash, and operates down to 1.8V, all in a tiny
3mm x 3mm LGA package.
Transient voltage suppressor (TVS) diodes are not all equal. The SDC36 TVS diodes have a clamping voltage less than 55V and
meet both IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT). There are many smaller TVS diodes out there that can't meet all of
these specifications.
Care must be taken when selecting resistors in a 24V (18V to 30V) system. Though designers may need the smallest size
components, avoid using resistors in an 0201 case size if they connect to 24V during normal operation. Resistors can fail by
exceeding their maximum working voltage even if their maximum power rating is not exceeded.
Santa Cruz uses an industry standard M12 connector allowing a 4-wire, or the conventional 3-wire, cable to be used to, keeping
costs low. The conventional way of adding six binary sensors would have required six sets of 3-wire cables. Now instead of six
binary sensors,six smart 14-bit sensors on a single IO-Link channel need only a single 3-wire cable. Santa Cruz does all this
while consuming less than 12mA (typ).

Detailed Description of Software
The Santa Cruz was verified using TMG TE's TMG IO-Link Device Tool V3, which comes with the purchase of the TMG-USB IO-
