Prolonged exposure to absolute maximum ratings may affect the performance and/or reliability of the device.
Serial data communication with the application is through the SPI interface. The 8 MSBs of an angular rate data
sample are mapped to the 8 bit response of the RARH (read angular rate high byte) command. The 4 LSBs of the
sample are mapped to the 4 LSBs of the 8 bit response of the RARLX (read angular rate low byte) command. The
RARH command latches the 4 LSBs of a sample such that a RARH, RARLX command sequence guarantees bits from
the same angular rate sample. The 4 MSBs of the response from the RARLX command is always a „0101‟ SPI error
check bit pattern.

Signal Definitions and Characteristics
According to AEC-Q100-002 Rev. C or JESD22-A114 Rev. F.
According to AEC-Q100-011 Rev. B or JESD22-C101 Rev. D.
According to MIL-STD 883E.
Signal Description
Master Out, Slave In.
After a negative edge on LOAD, 8-bit command is shifted in on MOSI, clocked by SCLK (MSB first).
Master In, Slave Out.
Output from previous command is stored in a Data Register. At a negative edge on LOAD, the
content of the Data Register is loaded to the Data Output Register. While command byte is shifted
into the Command Register, Data Output is shifted out on MISO (MSB first).
Chip Select/Transfer Start Strobe.
As long as LOAD=1, the MISO output is in a high-Z mode (tri-stated). A negative edge on LOAD
initiates an SPI transfer. The new command is executed after a positive edge on LOAD. If a positive
edge occurs on LOAD before at least 8 bits are shifted in on MOSI, the command will be ignored.
Serial Data Clock.
MOSI is read on the positive edge of SCLK, and MISO is shifted out on the negative edge of SCLK.
