ams datasheet page 1 [v2-04] 2015-oct-07 document feedback as5410 3d-hall absolute linear position sensor the chip can measure magnetic field components in two different orientation directions and converts the magnetic field information into absolute posi tion informatio n. the as5410 supports absolute linear positi on measurement applications. only a simple 2-pole magnet is required as the magnetic field source. using two 3d-hall cells allows both absolute as well as differential 3d magnetic field measurement. the differential measurement makes the as5410 ideal for use in rough industrial position se nsing applications that include not only dust, dirt or moisture but also unwanted magnetic stray fields. all the signal conditioning, including compensation of temperature effects, linearization of the output is included in the ic. the absolute position informatio n of the magnet is directly accessible over a spi interface and pwm output. a cycle redundancy check (crc) allows verification of the received data. the as5410 is available in a 14-pin tssop package and is qualified for an ambient temperature range from -40c to 105c. it operates at a supply voltage of 3.3v 10%. ordering information and content guide appear at end of datasheet. general description

ams datasheet page 15 [v2-04] 2015-oct-07 document feedback as5410 ? detailed description data transfer between as5410 and microcontroller data is transferred to the as5410 via the mosi pin (master out C slave in) with the rising edge of sck. data is read from the as5410 from the miso pin (master in C slave out) with the rising edge of sck. the data format consists of data streams with 32 bit in length. the first 16 bits define a 16-bit address and the subsequent 16 bits contain read or write data. the msb of the address word a<15> defines the direction of data transfer: a<15> = 0 read; data transfer from as5410 to microcontroller; read measurement data a<15> = 1 write; data transfer from microcontroller to as5410; write configuration data figure 17: data transfer between as5410 and microcontroller read mode for reading a register, the 16-bit read address (with a<15>=0) is sent to the mosi pin. after 16 sck cycles, data of the specified address is read from the miso pin (see figure 17 ). at the same time, the new address may be clocked into the mosi pin. miso ?0" + 15-bit address data 1 data 2 mosi miso read mode ?0" + 15-bit address ?0" + 15-bit address ?1" + 15-bit address previous command write mode & readback data 1 ?1" + 15-bit address previous command data 2 data 1 mosi
page 16 ams datasheet document feedback [v2-04] 2015-oct-07 as5410 ? detailed description continuous measurement it is possible to continuously read data from the as5410 even if a new measurement is not yet finished. in this case, the last measurement data will be read. as soon as a new measurement is completed, it will be available at the spi interface. write mode and readback for additional safety and dete ction of communication errors, the actual contents of a register may be read at the same time as new data is written to this register. in case of a write command, the 16-bit write address (with a<15>=1) is sent to the mosi pin. after 16 sck cycles, data following the address bits is written to the specified address via mosi in (see figure 17 ) at the same time, the present data of that register may be read from the miso pin. following the 16-bit of data (data 1 in figure 17 ), a new address may be written to the as5410. while the new address is written, the address from the previous command is available at the miso output. checksum to avoid reading errors, the ic calculates a checksum at every read cycle from the register content. the checksum value is built by an xor operation of the previous checksum value and the read register content. the crc is calculated every time a register is read. by choosing how often the checksum is read and rechecked by the master it is possible to ad just the communication speed and safety level. the checksum value is stored in register 0108h (see register description ).
ams datasheet page 17 [v2-04] 2015-oct-07 document feedback as5410 ? detailed description pwm data transmission in addition to the spi interface, the as5410 offers a pwm output that provides data transmission of the linearized output data over a single wire. the base frequency of the pwm is the system clock frequency, so one pwm digit always corresponds to approx. 125ns. the pwm resolution is set by 3 bits (pwmprescale) which shift the 16 bit wide angle value by 0 to 7 digits. the duty cycle of the pwm signal lies between 0% to 100%. in case of an error, the duty cycle is 0%. if register 0122h value increases the duty cycle decreases. if register 0122h value decreases the duty cycle increases. figure 18: register 000dh figure 19: single pin data transmission connection diagram register access bit function default note 000dh: pwm settings r/w d15-10 pwmlimithi <5:0> 0 pwm limit high, limits the pwm duty cycle to a maximum value d9-4 pwmlimitlo <5:0> 0 pwm limit low, limits the pwm duty cycle to a minimum value d3 pwmen 0 pwm enable, enables the pwm output d2-0 pwmprescale <2:0> 0 pwm prescale, sets pwm frequency and resolution as5410 c pwm pwm vdd vdd vss gnd vdd= 3.0 - 3.6v 100nf
