UC2550-13NNN

UC2550 Overview The efficiency of our UC2550 makes it ideal for low power applications. It is also our lowest cost UCM and offers a large complement of peripherals. Unlike the UC5550 however, it does not support USB host, a parallel LCD display, Ethernet PHY, or DCMI (Digital Camera Interface). We currently stock the UC2550 both with and without Wi-Fi depending on the model. We also offer customized, non-stock versions of our SoMs. See Options below for more information. Getting Started The UCM development options can greatly simplify the process of building a product or prototype using the UC2550. Options include a development board and displays which can get you programming in minutes. Please refer to the Development Optionspage for more information. Using TinyCLR OS TinyCLR provides a way to program the UC2550 in C# or Visual Basic from the Microsoft Visual Studio integrated development environment. To get started you must first install the bootloader and firmware on the UC2550 (instructions below) and then go to the TinyCLR Getting Started page for instructions on setting up the host computer and writing and deploying programs. Loading Bootloader Version 2 Download the UC2550 bootloader from here. Go to the Uploading DFU Files section of the STM32 Bootloader page for instructions on installing the bootloader. Loading the Firmware TIP First make sure you have bootloader v2 loaded. This needs to be done only once. To activate bootloader v2, hold the LDR0 signal low (press BOOT B on the UCM Dev and Breakout boards) and reset the board. You may have to wait a couple of seconds before releasing LDR0. Download the UC2550 firmware and follow the Loading the Firmware steps. Setup the Host Computer and Start Coding Now that you have installed the bootloader and firmware on the UC2550, you can setup your host computer and start programming. Go to the TinyCLR Getting Startedpage for instructions. Using Native Code with TinyCLR TinyCLR OS also lets you use native code that that works alongside your managed application. Native code can be used to provide improved performance or access to advanced features not exposed through TinyCLR. For more information check out Native Code on TinyCLR. TinyCLR cannot relocate native code, so you will have specify its location in the scatterfile. For the UC2550, the interop region starts at address 0x2003E000, and its length is 0x1FF8. Updating the Wi-Fi Module Firmware To update the firmware on the UC2550 Wi-Fi module, follow the instructions on this page. Schematic The schematic for the UC2550 can be found here. Options Model Number Wi-Fi External QSPI Flash UC2550-13NNN no no UC2550-13NNW yes no Customization We also offer customized, non-stock versions of our SoMs. Many options are available, such as various sizes of external QSPI flash. Please contact us for details. We will always do our best to provide you with a module to fit your exact needs.
