Fast access to clock and timer ICs when your project timeline matters
When a prototype deadline, lab course or production run can't wait, having clock and timer ICs in local stock removes weeks of lead time. Communica keeps a broad range of real-time clocks (RTCs), programmable timers, watchdogs and clock generators from maker-friendly brands and component manufacturers. That means fewer surprises, same-day branch collection from Samrand or Pretoria CBD, and VAT-compliant invoices for education or business purchases.
Why choose locally stocked clock/timer ICs
Local availability saves time and risk: immediate fit-testing on breadboards, quick swaps during lab sessions, and fast procurement for repair technicians. We stock parts suitable for students, hobbyists and engineers - from battery-backed RTC modules to low-power timers for IoT nodes. See our category range for an overview at Shop by Category.
Specification callouts that matter
When selecting a clock or timer IC, focus on these specs first: supply voltage range, timekeeping accuracy (ppm), backup/battery support, interface (I2C, SPI, 1-Wire), interrupt/output options, and package type for your PCB. Below is a compact comparison table to help narrow choices quickly.
| Type | Typical Interface | Key Strength | Typical Use |
|---|---|---|---|
| RTC (battery-backed) | I2C/SPI | Accurate calendar/time, battery backup | Data loggers, timestamping |
| Watchdog timer | GPIO/reset | System reliability, automatic reset | Embedded controllers, robotics |
| Programmable timer | Serial/GPIO | Flexible timing schedules | Automation, test rigs |
| Clock generator | Parallel/SI | Multiple clock outputs | FPGA/SoC systems |
Compatibility and accessory bundles
Many RTCs are designed for I2C buses and drop into common development boards - check address conflicts and pull-up resistor needs. For quick prototyping we offer accessory bundles: IC + CR2032 holder + header pins + example code snippets. For production, request tape-and-reel options and RoHS-compliant packaging where available.

Stock visibility and branch collection
Check live stock levels online or call ahead. If you need parts the same day, choose branch pickup - our Samrand warehouse and Pretoria CBD branches commonly hold popular RTCs and timers. See branch hours and collection details at Branches & Trading Hours.
