Application Design Equations
The bandwidth is determined by the internal 1kHz low pass filter. The user can lower the bandwidth by placing
filter capacitors connected from pins 2, 13 and 14 to ground. The response is single pole. Given a desired
bandwidth, f BW , the filter capacitors are determined by:

KXR94 Digital Interface
The Kionix KXR94 digital accelerometer has the ability to communicate on a SPI digital serial interface bus.
This flexibility allows for easy system integration by eliminating analog-to-digital converter requirements and by
providing direct communication with system micro-controllers.
The serial interface terms and descriptions as indicated in Table 6 below will be observed throughout this
document.

Description
The device that transmits data to the bus.
The device that receives data from the bus.
The device that initiates a transfer, generates clock signals and terminates a transfer.
The device addressed by the Master.
SPI Interface
The KXR94 utilizes an integrated Serial Peripheral Interface (SPI) for digital communication. The SPI interface
is primarily used for synchronous serial communication between one Master device and one or more Slave
devices. The Master, typically a micro controller, provides the SPI clock signal (SCLK) and determines the
state of Chip Select (nCS). The KXR94 always operates as a Slave device during standard Master-Slave SPI
operation.
SPI is a 4-wire synchronous serial interface that uses two control and two data lines. With respect to the
Master, the Serial Clock output (SCLK), the Data Output (MOSI) and the Data Input (MISO) are shared among
the Slave devices. The Master generates an independent Chip Select (nCS) for each Slave device that goes
low at the start of transmission and goes back high at the end. The Slave Data Output (SDO) line, remains in
a high-impedance (hi-z) state when the device is not selected, so it does not interfere with any active devices.
This allows multiple Slave devices to share a master SPI port as shown in Figure 1 below.
