Product details
Overview
ZSSC3135BE2R from Integrated Device Technology (IDT) is a CMOS sensor signal conditioner IC designed specifically for piezoresistive bridge sensors in automotive and industrial applications. It delivers 13/14-bit ADC resolution, analog gain up to 105, ratiometric analog voltage output (12.4-bit effective), and digital ZACwire™ One-Wire interface. Its internal 16-bit RISC microcontroller performs real-time digital compensation of offset, sensitivity, temperature drift, and non-linearity - calibrated once and stored in on-chip EEPROM.
For engineers reviewing the ZSSC3135BE2R datasheet, ZSSC3135BE2R pinout, ZSSC3135BE2R application, or ZSSC3135BE2R equivalent, this page provides verified technical context, JEDEC-SSOP14 package mapping, calibrated accuracy specs (0.25% FSO @ −25 to +85°C), safety features including sensor connection loss detection, and confirmed alternatives for piezoresistive bridge signal conditioning.
Technical Context
The ZSSC3135BE2R implements a fully differential analog front-end with programmable gain amplifier (PGA) supporting gains from 2.8 to 105, enabling precise amplification of low-level mV/V bridge outputs while maintaining common-mode input range of 29–65% VDDA. Its measurement cycle sequences bridge signal, internal/external temperature sensor, and auto-zero inputs under control of an embedded 16-bit RISC calibration microcontroller (CMC).
Digital conditioning uses ROM-stored correction algorithms and EEPROM-stored sensor-specific coefficients to compute compensated output. Output options include ratiometric analog voltage (5–95% VDDE, 12-bit DAC) or ZACwire™ serial readout - both configurable via I²C™ or ZACwire™ during one-pass end-of-line calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 13/14-bit - determines raw digitization fidelity before digital correction; enables ≤0.5% FSO total error over −40 to +125°C. |
| Analog Gain Range | 2.8 to 105 - sets input span compatibility with bridge sensors from 8 to 275 mV/V; gain 105 supports high-sensitivity piezoresistive elements. |
| Output Options | Ratiometric analog voltage (5–95% VDDE, 12-bit DAC) or ZACwire™ One-Wire - allows direct analog interfacing or low-pin-count digital readout without external protocol logic. |
| Accuracy (FSO) | 0.25% @ −25 to +85°C; 0.5% @ −40 to +125°C - guaranteed after one-pass calibration; includes INL, gain, offset, and temperature error contributions. |
| Operating Temperature | −40°C to +150°C - qualified per AEC-Q100; extended range enabled by die-level thermal design and high-voltage protection circuitry. |
| Supply Voltage | 4.5 V to 5.5 V - tightly regulated requirement ensures stable reference for ratiometric output and accurate ADC conversion. |
| Sample Rate | Up to 200 Hz - bandwidth-limited by integrating ADC architecture; sufficient for pressure, force, and level sensing in dynamic industrial environments. |
Pinout & Package
Package: RoHS-compliant JEDEC-SSOP14 (5.3 mm × 6.2 mm, 0.635 mm pitch), rated for −40°C to +150°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA | Analog supply input | Provides clean 4.5–5.5 V power to analog front-end; must be decoupled with ≥100 nF capacitor near pin. |
| VSSA | Analog ground reference | Separate analog ground return; requires star-point connection to avoid noise coupling into sensitive bridge inputs. |
| VBR_T / VBR_B | Bridge top/bottom differential inputs | Accepts full Wheatstone bridge output; differential design rejects common-mode noise and enables bidirectional signal handling. |
| VBP / VBN | Bridge excitation bias outputs | Provides programmable voltage bias to bridge; eliminates need for external bias resistors or regulators. |
| AOUT | Analog output | Ratiometric voltage output (5–95% VDDE); drives ≥2 kΩ load with 0.1 V/µs slew rate and <10 mVpp noise (≤10 kHz). |
| SDA / SCL | I²C™ interface pins | Support configuration and calibration via standard I²C™ bus (up to 400 kHz); open-drain with internal 25–100 kΩ pull-ups. |
| IRTEMP | External temperature sensor input | Accepts diode or thermistor-based temperature sensing; supports optional external compensation for improved thermal error correction. |
| VSSE | Signal ground reference | Reference for AOUT and OWI output; isolated from VSSA to minimize ground loop interference in noisy systems. |
| OUT / OWI | ZACwire™ One-Wire output | Digital output pin supporting IDT's proprietary ZACwire™ protocol; enables single-wire communication with host MCU. |
| VDD | Digital supply input | Shares same 4.5–5.5 V rail as VDDA in most designs; internal regulation isolates digital logic from analog supply noise. |
| n.c. | No-connect | Pin 5 is unconnected; must remain floating or tied to VSSE per layout guidelines to prevent parasitic coupling. |
| VDDE | Power supply input | Main supply pin; accepts 4.5–5.5 V; integrates reverse polarity and short-circuit protection up to ±33 V transient tolerance. |
Key Features
| Feature | Design Value |
|---|---|
| Digital compensation engine | Embedded 16-bit RISC microcontroller executes ROM-stored correction algorithm using EEPROM-stored coefficients - eliminates need for external DSP or firmware development. |
| One-pass calibration | Factory or end-of-line calibration writes all coefficients in single I²C™ or ZACwire™ session - reduces production test time and avoids manual trimming components. |
| High-voltage robustness | Withstands ±33 V transients on VDDE and AOUT pins - meets ISO 7637-2 pulse 5a requirements for automotive 12 V systems without external TVS. |
| Sensor health monitoring | Detects open-circuit (>100 kΩ) and short-circuit (<50 Ω) conditions on bridge inputs - enables fail-safe diagnostics in safety-critical pressure or force sensing. |
| Temperature compensation flexibility | Supports internal diode, external diode, or external thermistor temperature sensing - allows trade-off between cost (internal) and accuracy (external) per application needs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar piezoresistive bridge signal conditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum operating temperature range supported by the ZSSC3135BE2R?
The ZSSC3135BE2R is specified for operation from −40°C to +150°C and is AEC-Q100 qualified for automotive use. This extended temperature range is enabled by its SSOP14 package construction and internal protection circuitry - making it suitable for under-hood automotive pressure sensing and high-temperature industrial environments where standard −40°C to +125°C devices would fail.
Does the ZSSC3135BE2R require external components for basic operation?
The ZSSC3135BE2R requires minimal external components: two 100 nF decoupling capacitors on VDDA and VDD, a 47 nF capacitor on AOUT, and optionally an external temperature sensor. No external trimming resistors, reference voltages, or calibration hardware are needed - all compensation parameters are stored in on-chip EEPROM and applied automatically by the embedded microcontroller.
How is calibration performed for the ZSSC3135BE2R?
Calibration for the ZSSC3135BE2R is performed via one-pass end-of-line procedure using either the I²C™ or ZACwire™ interface. During calibration, known pressure/force points are applied to the connected bridge sensor, and the ZSSC3135BE2R's internal microcontroller computes and stores offset, sensitivity, temperature drift, and non-linearity coefficients directly into its EEPROM - eliminating manual trimming and enabling full digital correction without host intervention.
Can the ZSSC3135BE2R interface with a microcontroller lacking I²C™ support?
Yes - the ZSSC3135BE2R supports ZACwire™, a proprietary single-wire digital interface compatible with any GPIO-capable microcontroller. ZACwire™ requires only one I/O pin and a simple bit-banged driver; IDT provides reference firmware and protocol documentation. This enables integration with resource-constrained MCUs that lack dedicated I²C™ peripherals.
What safety features does the ZSSC3135BE2R include for sensor fault detection?
The ZSSC3135BE2R includes built-in sensor health monitoring: it detects open-circuit conditions (>100 kΩ) and short-circuit faults (<50 Ω) on bridge inputs, reports diagnostic status via ZACwire™ or I²C™, and maintains safe output behavior. These features are implemented in hardware and do not require host MCU polling - ensuring fail-safe operation in ASIL-B–level automotive and industrial safety systems.
