Product details

What this mobile I/O companion does

The LM8333GGR8AXS/NOPB is a dedicated controller that offloads keypad, GPIO, and accessory management from the main application processor in mobile handsets and portable devices. It communicates over I²C or ACCESS.bus, so the host only sees register reads instead of polling discrete inputs. Supply range is 2.25V to 2.9V — it runs directly off a 2.5V or 2.8V battery rail without a separate LDO. The 6 mA typical supply current keeps the power draw negligible in sleep-heavy designs.

Package and temperature grade for the BOM

Housed in a 49-ball CSPBGA (4x4 mm) — the ball pitch demands a controlled-impedance fan-out on a 4-layer PCB.
