Datasheets are not made equal. Some datasheets, including the LPC2148 Datasheet, are more comprehensive than others. This means it will include important information, such as the clocking or crystal frequencies. Also included is a small table of the pin descriptions. It’s important to cross reference across the datasheet, to avoid conflicts, such as:
| Pin Name | Description |
|---|---|
| P0.0 | GPIO, TXD0 |
| P0.1 | GPIO, RXD0 |
The datasheet serves as the foundation for writing code, designing PCBs, and troubleshooting problems. For instance, when configuring a UART peripheral, the datasheet provides the register addresses, bit definitions, and baud rate settings required for proper communication. Similarly, when designing the power supply, the datasheet specifies the voltage and current requirements of the microcontroller. Without consulting the datasheet, developers are working in the dark, relying on guesswork and potentially leading to incorrect and unreliable systems. Understanding every parameter of the components of your system is key in ensuring they do not damage themselves. The LPC2148 Datasheet ensures this process is as smooth as possible, and the components are used safely.
To truly master the LPC2148 and unlock its full capabilities, it’s essential to delve into the source. Read the detailed specifications and diagrams in the LPC2148 Datasheet available to you.
