The QT60161B digital charge-transfer (“QT”) QMatrix IC is designed to detect human touch on up 16 keys when used in
conjunction with a scanned, passive X-Y matrix. It will project the keys through almost any dielectric, e.g. glass, plastic, stone,
ceramic, and even wood, up to thicknesses of 5 cm or more. The touch areas are defined as simple 2-part interdigitated
electrodes of conductive material, like copper or screened silver or carbon deposited on the rear of a control panel. Key sizes,
shapes and placement are almost entirely arbitrary; sizes and shapes of keys can be mixed within a single panel of keys and can
vary by a factor of 20:1 in surface area. The sensitivity of each key can be set individually via simple functions over the SPI or
UART port, for example via Quantum’s QmBtn program, or from a host microcontroller. Key setups are stored in an onboard
eeprom and do not need to be reloaded with each powerup.
The device is designed specifically for appliances, electronic kiosks, security panels, portable instruments, machine tools, or
similar products that are subject to environmental influences or even vandalism. It can permit the construction of 100% sealed,
watertight control panels that are immune to humidity, temperature, dirt accumulation, or the physical deterioration of the panel
surface from abrasion, chemicals, or abuse. To this end the device contains Quantum-pioneered adaptive auto self-calibration,
drift compensation, and digital filtering algorithms that make the sensing function robust and survivable.
The part can scan matrix touch keys over LCD panels or other displays when used with clear ITO electrodes arranged in a matrix.
It does not require 'chip on glass' or other exotic fabrication techniques, thus allowing the OEM to source the matrix from multiple
vendors. Materials such as such common PCB materials or flex circuits can be used.
External circuitry consists of a resonator and a few capacitors and resistors, all of which can fit into a footprint of less than 6 sq. cm
(1 sq. in). Control and data transfer is via either a SPI or UART port; a parallel scan port provides backwards compatibility with
scanned electromechanical keys.
The QT60161B makes use of an important new variant of charge-transfer sensing, transverse charge-transfer, in a matrix format
that minimizes the number of required scan lines. Unlike some older technologies it does not require one sensing IC per key.
The QT60161B is identical to earlier QT60161 in all respects except that the device exhibits lower signal noise. This
device replaces QT60161 parts directly. After December 2003 the QT60161 will no longer be sold.
