Why buy communication ICs from Communica in South Africa
Need reliable comms silicon fast for a prototype, lab course or production run? Communica stocks thousands of components and keeps many common communication ICs in local warehouses to reduce lead times. That means engineers, technicians and university labs can check stock, collect from Samrand or Pretoria CBD, or request an account quote with VAT invoice for procurement. Shop Now and Check Stock in Samrand are common next steps for projects on tight timelines.
Common communication IC families we carry
We focus on practical availability for South African projects: UART/USART transceivers, SPI/I2C buffers, RS-232/RS-485 drivers, CAN transceivers, Ethernet PHYs, Wi-Fi/Bluetooth combo modules and RF transceivers for ISM bands. Popular brands and maker-friendly ranges are available; see our Shop by Brand page for full listings.
- UART/level-shifting and RS-232/485 transceivers
- CAN bus transceivers for automotive and industrial prototypes
- Ethernet PHYs and magnetics for wired network endpoints
- Sub-GHz and 2.4 GHz RF transceivers for telemetry and IoT
Specification callouts to check before you buy
Confirm these specs to match your design: logic voltage (1.8V / 3.3V / 5V), data rate, interface type, required external components (crystals, matching networks), package and thermal dissipation. For board-level integration check available EVMs or modules to accelerate development. Compare Specs to confirm the right footprint and power envelope.
| Type | Key specs | Typical use |
|---|---|---|
| RS-485 Transceiver | Half/full duplex, ±12V tolerance, 10 Mbps | Long-run serial comms, industrial networks |
| CAN Transceiver | ISO 11898 compatible, 1 Mbps, thermal protection | Vehicle networks, motor control |
| Ethernet PHY | 10/100/1000 Mbps, MII/RMII/RGMII | Networked devices, gateways |
Quick compatibility checklist
Match logic voltage, check package pinout, verify whether transceivers need external terminators or magnetics, and confirm regulatory band restrictions for RF modules in South Africa. If you need help, Request a Quote and our technical sales team can suggest pin-compatible alternatives and accessory bundles.
