  A1333
  2 -Precision, High Speed, Hall-Effect Angle Sensor IC
  with Integrated Diagnostics for Safety-Critical Applications FEATURES AND BENEFITS DESCRIPTION Contactless 0° to 360° angle sensor IC, for angular
  position, rotational speed, and direction measurement
  â–¡â–¡ Capable of sensing magnet rotational speeds targeting
  12b effective resolution with 900 G field
  â–¡â–¡ Circular Vertical Hall (CVH) technology provides a
  single channel sensor system supporting operation
  across a wide range of air gaps Developed in accordance with ISO 26262:2011
  requirements for hardware product development for use
  in safety-critical applications (pending assessment)
  â–¡â–¡ Single die version designed to meet ASIL B
  requirements when integrated and used in conjunction
  with the appropriate system-level control, in the
  manner proscribed in the A1333 Safety Manual
  â–¡â–¡ Dual die version designed to meet ASIL D
  requirements when integrated and used in conjunction
  with the appropriate system-level control, in the
  manner proscribed in the A1333 Safety Manual High diagnostic coverage
  â–¡â–¡ On-chip diagnostics include logic built-in self-test
  (LBIST), signal path diagnostics, and watchdogs to
  support safety-critical (ASIL) applications
  â–¡â–¡ 4-bit CRC on SPI On-chip EEPROM for storing factory and customer ...
