Description for the LM8330

The LM8330 I/O - Expander and Keypad Controller is a dedicated device designed to unburden a host processor from scanning a matrix-addressed keypad and to provide flexible and general purpose, host programmable input/output functions. Three independent Pulse Width Modulation (PWM) timer outputs are provided for dynamic LED brightness modulation.

It communicates with a host processor through an I2C-compatible ACCESS.bus serial interface. It can communicate in Standard (100 kHz) and Fast-Mode (400 kHz) in slave Mode only.

All available input/output pins can alternately be used as an input or an output in a keypad matrix or as a host-programmable general-purpose input or output.

Any pin programmed as an input can also sense hardware interrupts. The interrupt polarity (“high-to-low” or “low-to-high” transition) is thereby programmable.

The LM8330 follows a predefined register-based set of commands. Upon startup (power-on) a configuration file must be sent from the host to set up the hardware of the device.

The LM8330 is available in a 25-bump lead-free DSBGA package size 2.0 mm x 2.0 mm x 0.6 mm (0.4 mm pitch).

The LM8330 has integrated ASIP (Application Specific Integrated Passives) on the KPX[7:0] and KPY[10:0] pins. These pins are designed to tolerate IEC61000-4-2 level 4 ESD: ±8 kV direct contact.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
