Hardware Migration & Drop-In Checklist
Detailed board-level verification checklist for hardware design engineers transitioning to Cosine COS13488EESA.
1. Pinout Verification (100% Direct Match)
The solder footprint, mechanical pitch (1.27mm), and pin functions of Cosine COS13488EESA strictly conform to the industry-standard JEDEC SOP-8 (JEDEC MS-012) specification. No PCB traces or vias require modification.
| Pin 1 | RO | Receiver Output |
| Pin 2 | RE | Receiver Enable (Active Low) |
| Pin 3 | DE | Driver Enable (Active High) |
| Pin 4 | DI | Driver Data Input |
| Pin 5 | GND | Ground |
| Pin 6 | A | Non-Inverting RS-485 Bus |
| Pin 7 | B | Inverting RS-485 Bus |
| Pin 8 | VCC | 5V Power Supply |
2. Decoupling & Peripheral Passive Rules
- Bypass Capacitor: Keep existing 0.1 µF (100 nF) X7R ceramic capacitor placed within 3 mm of the power pin.
- Ground Plane: Direct solid ground return plane beneath the IC minimizes parasitic loop inductances.
- Differential Routing: Symmetrical trace width and spacing for high-frequency differential bus pairs.
- Hot-Swap Sequencing: Integrated on-chip hot-plug glitch suppression eliminates transient bus contention during live card insertion.

Engineering FAE Migration FAQ
How does COS13488 handle high-speed 12 Mbps Profibus-DP networks?
COS13488 features optimized slew rates with sub-35ns propagation delays, fully satisfying Profibus-DP timing requirements and bit-width symmetry constraints.
Is external bus biasing required?
The internal true fail-safe receiver architecture guarantees a logic-high output when bus lines are open or shorted, eliminating the need for external pull-up/pull-down resistors.
What termination resistor should be used on long cables?
Install a standard 120-ohm metal film resistor across pin A and pin B at both extreme physical ends of the differential transmission cable.
