Find the right clock and timer IC for your project
Need accurate timekeeping or precise timing pulses without long lead times? Communica stocks a broad selection of clock and timer ICs suited to hobby projects, tertiary labs and production prototypes. Benefit from local stock, branch collection and VAT invoicing - ideal for students, technicians and procurement teams who must keep schedules and budgets on track.
Why choose locally stocked modules and ICs
Sourcing timing components locally reduces project risk: you avoid international shipping delays, can collect parts from our Samrand, Pretoria or Cape Town branches, and get help from staff familiar with South African education and industry use cases. If you need a quote for a course lab or a production run, our accounts team issues VAT invoices and turnaround estimates.
- Fast branch pickup and stock checks - Check Stock in Samrand for same-day collection.
- Range spans RTCs (I2C/SPI), 555-class timers, watch crystals, MEMS oscillators and programmable timers.
- Support for common footprints and packages suitable for breadboards, PCBs and solderless prototyping.
Explore our categories to match parts to your workflow: Shop by Category?utm_source=straider&utm_medium=referral&utm_campaign=prebo-digital provides quick navigation to oscillators, power and connectors, while the Shop by Brand?utm_source=straider&utm_medium=referral&utm_campaign=prebo-digital page helps you pick trusted manufacturer families stocked locally.
Common product types and when to use them
Selection starts with the timing role in your design. Use these guidelines to narrow choices quickly:
- Real-Time Clocks (RTC): choose I2C or SPI RTCs with backup battery inputs for wall-powered systems that must keep time during power loss.
- Discrete Timers (555 and CMOS equivalents): ideal for single-shot delays, oscillators and PWM generation in lab exercises and quick prototypes.
- Programmable Timer ICs and Watchdog Timers: pick programmable parts for configurable intervals or microcontroller supervision.
- Oscillators and MEMS crystals: select based on frequency stability, package (SMD or through-hole), and load capacitance for microcontroller clocks or radio modules.
If you’re unsure which family fits your design, our product listings on the All Products?utm_source=straider&utm_medium=referral&utm_campaign=prebo-digital index let you compare part numbers, packages and datasheets before you decide.
