Buying Guide
Summary

Renesas Electronics Corporation 1338B-18DVGI8 is used in Real Time Clocks category where integration and verification need to stay predictable. Key specs include Description (1338B-18 REAL TIME CLOCK), Type (Clock/Calendar), Packaging (Tape & Reel (TR)), Supply (1.4V ~ 5.5V), and Temperature (-40°C ~ 85°C (TA)).

Selection Notes
  • For 1338B-18DVGI8, confirm the memory size (56B) meets your data logging and storage capacity targets.
  • Confirm the operating temperature range (-40°C ~ 85°C (TA)) meets your deployment conditions.
  • Validate Current - Timekeeping (Max) (2µA @ 3.3V) under the expected test conditions in your application.
  • Make sure the mounting type (Surface Mount) matches how the part will be installed and inspected.
Alternates & Substitutions
  • For Real Time Clocks, treat alternates as an integration task and validate the assumptions that matter on the assembled system.
  • Make sure the alternate stays inside your system envelope: supply 1.4V ~ 5.5V, temperature -40°C ~ 85°C (TA).
  • For substitutions, match the footprint-related items first: package/case 8-TSSOP, 8-MSOP (0.118", 3.00mm Width), supplier package 8-TSSOP, mounting Surface Mount.
  • For production substitutions, confirm traceability and documentation expectations so the alternate can be released cleanly.

Application Scenarios

In the Real Time Clocks category, Renesas Electronics Corporation 1338B-18DVGI8 is often evaluated by how well it fits electrical, thermal, and mechanical constraints in the target system. In many platforms, clock parts directly influence BER, sampling accuracy, and long-term stability during 24/7 operation. Timing devices are often chosen for predictable startup, stable jitter performance, and clean distribution across noisy boards. In measurement equipment, clean clocks reduce spurs and improve repeatability in calibration workflows. Across industrial motion control, they stabilize capture timing and PWM generation in servo drives exposed to inverter EMI and large thermal gradients. Across automotive infotainment and camera links, they support high-speed interfaces that must tolerate thermal cycling and vibration without frame errors. In measurement equipment, clean clocks reduce converter spurs and improve repeatability in benchtop instruments used for calibration workflows.

Compatibility Advice
  • In practice, confirm jitter/phase-noise assumptions with the real power and grounding so system timing margins remain measurable on the assembled PCB.
Project Fit
  • Good fit when you can measure and verify Renesas Electronics Corporation 1338B-18DVGI8 for Real Time Clocks integration across temperature and supply corners, and you have defined jitter budgets and controlled routing for clock distribution.
  • Poor fit when routing constraints prevent controlled impedance and clean return paths, because it becomes difficult to prove margin across production variance.
