... QT60326. On the QT60326, only the first 4 Y lines (Y0..Y3) are operational by default. On the QT60326, to use keys located on lines Y4 and Y5, one or more of the pre-enabled keys must be disabled simultaneously while enabling the desired new keys. This can be done in one Setups block load operation. ...

Response Time The response time of the device depends on the scan rate of the keys (Section 5.13), the number of keys enabled (Section 5.4), the detect integrator settings (Section 5.4), and the serial polling rate by the host ...

Serial Communications These devices can use either SPI or UART communications modes; it cannot use both at the same time. The part defaults to SPI mode unless it receives a byte over the UART interface UART byte ...
Page 12
SPI communications operates in slave mode only, and obeys DRDY control signaling. The clocking is as follows: Clock idle: High Clock shift out edge: Falling Clock data in edge: Rising Max clock rate: 4MHz SPI mode requires 5 signals to ...
Page 13
Multi-drop capability: Tx floats within 10µs after each transmitted byte. This line can thus be shared with other UART based peripherals. Tx includes an internal 20K ~ 50K pull-up resistor to Vdd to prevent the line from floating down. Wake ...
Page 14
In SPI communications, when the QT60xx6 responds to a command with one or more response bytes, the host can issue a new command instead of a null on the last byte shift operation. New commands during intermediate byte shift-out operations ...

A CRC byte is appended to the response to the 0x05 command; this CRC folds in the command value 0x05 itself initially. 4.6 Report 1st Key - 0x06 Reports the first or only key to be touched, plus indicates if ...

This command requires substantial amounts of time to process and return a result not recommended to use this command except perhaps on startup or very infrequently. Command response timing: The response to this command can take as long ...

Power On or Hardware Reset Note: CRC errors or incorrect responses should cause each transmission to retry where changes are specifically required, such as for sensiti vity, timing, or AKS changes. The circles in this drawing are communications interchanges between ...

External fields can cause interference leading to false detections or sensitivity shifts. Most fields come from AC power sources. RFI noise sources are heavily suppressed by the low impedance nature of the QT circuitry itself. Noise such as from 50Hz ...
