AS5510 − Detailed Description

I²C Interface

The AS5510 includes an I²C slave according to the NXP

specification UM10204.

• 7-bit slave address 101011x, the last address bit x is set

by the ADR pin (0 or 1)

• Random/Sequential Read

•Byte/Page Write

• Fast-mode plus with 20mA SDA drive strength

• Internal hold time of 120ns for SDA signal is included

(Start/Stop detection)

Not implemented:

• 10-bit Slave Address

•Clock Stretching

• General Call Address

• General Call – Software Reset

•Read of Device ID

The communication from the AS5510 includes:

• Reading the magnetic field strength in 10-bit data

• Reading the status bits

Note(s): The I²C address of the chip is selected by hardware (pin

ADR). Depending on the state of this pin, the I²C address is

either:

•Pin ADR = LOW  I²C address = 1010110b(56h)

• Pin ADR = HIGH  I²C address = 1010111b(57h)
