ZSSC3281BI5B中文资料瑞萨数据手册PDF规格书

• Digital communication and calibration interfaces:

o SPI up to 10MHz

o I2C (Standard, Fast, Fast+) and I3C SDR

o One-wire-interface (OWI), up to 100kBit/s

• Accommodates nearly all resistive bridge sensor

types (signal spans from 1mV/V up to 500mV/V)

• Supports different sensor element configurations:

o Resistive bridge or half-bridge

o Resistive divider string

o Voltage source

• On-chip temperature sensor

• External temperature sensing supported, for

example, sensor-bridge as temperature detector,

external diode, etc.

• Programmable 16-bit digital-to-analog-converter

and output (supporting “True-0Volt”-output):

o (0V to 1V) or (0V to 5V) absolute voltage output

o VDD-ratiometric voltage output

o 4mA to 20mA current-loop output supported

o 0V to 10V absolute-voltage output supported

• Wide operational temperature and supply range

• On-chip voltage regulators for sensor supply, and IC operation

• Support for extra regulation by external

transistor, for example, JFET (especially for

industrial supply voltages >5.5VDC)

• Programmable sensor-signal-conditioning math core

• Reprogrammable, nonvolatile memory (NVM)

• On-chip diagnostics:

o Sensor connection

o AFE self-test

o Memory integrity
