The supply range of 1.65V to 3.6V lets it bridge 1.8V and 3.3V logic domains without a level shifter — useful when the MCU runs at 1.8V but the keypad backlight or external sensors need 3.3V. ## Package and rework — the 24-LFCSP exposed pad This part comes in a 24-LFCSP-WQ measuring 3.5x3.5 mm with an exposed pad underneath. That pad is the thermal and electrical ground connection — it needs a via-in-pad or a thermal land pattern on the PCB to sink heat and keep the device stable during reflow. The exposed pad is also the only way to get a solid ground return for the I²C signals; a floating pad can cause erratic bus behavior. For rework, the small body and fine pitch mean a hot-air station with a nozzle smaller than 4 mm is the tool to use. Pre-bake at 125°C for 8 hours if the moisture-barrier bag has been open longer than the floor life — the LFCSP package is MSL 3 and can pop if reflowed wet.","metaTitle":"ADP5589ACPZ-00-R7 I²C Keypad / I/O Expander, 1.65V–3.6V","metaDescription":"ADI ADP5589ACPZ-00-R7 I²C keypad entry and I/O expansion IC in 24-LFCSP (3.5x3.5mm).

The supply range is 1.65V to 3.6V, so 3.3V is well within the operating window. The I²C bus logic levels track VDD, meaning a 3.3V supply gives 3.3V-compatible SDA/SCL signaling."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADP5589ACPZ-00-R7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADP5589ACPZ-00-R7 when reusing this data.
