Are you working on a project that requires a low-cost microcontroller, but you're not sure which one to choose? Well, you're in the right place. In this post, we will compare two low-cost microcontrollers, the LPC176x and LPC214x, so you can make an informed decision based on your project's requirements.
LPC176x
The LPC176x is a low-power microcontroller that runs on an ARM Cortex-M3 processor at speeds of up to 100 MHz. It has up to 512 KB of flash memory and 32 KB of SRAM, making it ideal for embedded systems with limited memory requirements. It also features a variety of communication interfaces, including Ethernet, USB, UART, SPI, and I2C, making it easy to connect to other devices.
One of the standout features of the LPC176x is its power efficiency. It has a low-power mode that allows it to operate at just a few microamps of current, making it ideal for battery-powered applications. It also has an on-chip voltage regulator that can provide stable power to other components in the system.
LPC214x
The LPC214x is also an ARM-based microcontroller that operates at speeds of up to 60 MHz. It has up to 512 KB of flash memory and 32 KB of SRAM, which is similar to the LPC176x. However, it has fewer communication interfaces than the LPC176x, with only UART, SPI, and I2C available.
One advantage the LPC214x has over the LPC176x is its small size. It comes in a smaller package, making it ideal for applications where space is limited. It also has a higher operating temperature range, with some models able to operate up to 105 degrees Celsius.
Comparison
Here's a quick comparison of the key features of the LPC176x and LPC214x:
| LPC176x | LPC214x | |
|---|---|---|
| Processor | ARM Cortex-M3 | ARM7 |
| Maximum speed | 100 MHz | 60 MHz |
| Flash memory | Up to 512 KB | Up to 512 KB |
| SRAM | 32 KB | 32 KB |
| Communication interfaces | Ethernet, USB, UART, SPI, I2C | UART, SPI, I2C |
| Power consumption | Low-power mode available | N/A |
| Package size | Larger | Smaller |
| Operating temperature range | -40 to 85 degrees Celsius | -40 to 105 degrees Celsius |
As you can see, both microcontrollers have similar specifications, with the LPC176x having more communication interfaces and power efficiency, while the LPC214x has a smaller size and higher operating temperature range.
Conclusion
Choosing between the LPC176x and LPC214x ultimately comes down to your project's specific requirements. If you require more communication interfaces and power efficiency, the LPC176x is the better option. However, if you require a smaller size and higher operating temperature range, the LPC214x is a viable alternative.
