MAX32664GWED
The finger-based Blood Pressure Trending (BPT),
heart rate and SpO
2
monitoring algorithm (100Hz
Sampling).
The algorithm is compatible with the sensor hub
combination
of
the
MAX32664GWED
and
MAX30101 AFE. No accelerometer is required for
this algorithm.
The BPT algorithm includes Automatic gain control
to adjust LED currents.
Prior to running the algorithm, a calibration
procedure is required to determine blood pressure
and SpO
2
calibration coefficients.
Automatic gain control (AGC). If the AGC is enabled,
the LED currents and pulse width are automatically
determined by the algorithm. If the AGC is not
enabled, the LED currents and pulse width registers
should be configured by the host software.

Z-keyed algorithm/firmware of the above which
may be used to in-application program the Maxim
Integrated reference designs listed or for boards
that use the MAX32664GWEZ.

For all the MAX32664 parts, the algorithm (.msbl file) with the corresponding bootloader key must be
downloaded, and these parts must be programmed using the in-application programming feature of the
bootloader.
The MAX32664 is only pre-programmed with the bootloader software.
