Product Description

Product Overview

The PST-360 is a sensor featuring a digital Serial Peripheral Interface (SPI) protocol. It operates as a slave node, providing angle measurement data. The device is designed for applications requiring precise angular positioning and communicates via a three-wire protocol (/SS, SCLK, MOSI-MISO). It offers a 360 ERA (Electronic Resolution Angle) and supports a simple SPI protocol.

SPI Protocol - Slow Mode Timing (Oscillator 7MHz)	t1: 6.9 s (Min) t2: 37.5 s (Min) t4: 6.9 s (Min) t5: 1500 s (Min) t6: 6.9 s (Min) t7: 45 s (Min) t9: TStartUp:	t5: Minimum time between reset-inactive and any master signal change. t7: Minimum time between StartByte and Byte0. TStartUp: Slave start-up time after power-up or internal failure.
SPI Protocol - Data Frame Structure	10 bytes total	2 start bytes (AAh, FFh), 2 data bytes (DATA16), 2 inverted data bytes (/DATA16), 4 all-Hi bytes.
SPI Protocol - Frame Transmission	Asynchronous	No inter-frame time defined.
SPI Protocol - Slave Reset	Master deactivates /SS high for at least t5 (1.5 ms) to synchronize.	Slave resets after 1 second or after an error frame on internal soft failures.
SPI Protocol - Slave Start-Up	16 ms	Serial protocol link enabled after first synchronization. /SS and SCLK ignored during start-up.
SPI Protocol - Error Handling	MOSI/MISO pin remains Hi-impedant for ROM CRC, EEPROM CRC, RAM check, intelligent watchdog errors.	For other errors, serial protocol is initialized and error condition is readable. Slave performs soft reset after sending error frame.
