PAH8001EI-2G
Optical Heart Rate Detection Sensor
General Description
The PAHEI-2GEI-2G is a high performance and low power CMOS-process optical sensor with Green LED and DSP
integrated serving as a Heart Rate Detection (HRD) sensor. It is based on optical technology which measures the
variation of human blood movement in the vessel.

2. Four-Wire SPI Interface (For PAH8001EI-2G)
CSN_ID1 : Chip select line, active low(Generally named SPI_CS).
SCK : Serial clock line, generated by the host controller.
CSN_ID0 : Serial data line, used to write data to sensor(Generally named MOSI).
SDIO : Serial data line, used to read data from sensor(Generally named MISO).
2.1. Transmission Protocol
The transmission protocol is a 4-wire link, half duplex protocol between the micro-controller and the sensor. All data
changes on SDI_ID0/SDIO are latched at SCK rising edge. The host controller always initiates communication and the
sensor never initiates data transfers.
The transmission protocol consists of the two operation modes:
- Write Operation.
- Read Operation.
Both of the two operation modes consist of two bytes. The first byte contains the address (seven bits) and has a bit 7 as
its MSB to indicate data direction. The second byte contains the data.

2.2. Write/Read Operation
Write Operation
A write operation, which means that data is going from the host controller to the sensor, is always initiated by the
controller and consists of two bytes. The first byte contains the address (seven bits) and has a “1” as its MSB to
indicate data direction. The second byte contains the data. The transfer is synchronized by SCK. The controller changes
SDI_ID0 at SCK falling edges. The sensor reads SDI_ID0at SCK rising edges.
