由于RT系列没有内置 Flash，大多数用户会选择外部 QSPI Flash 作为应用代码和数据的非易失存储设备，同时外部Flash的大容量在满足用户代码存储需求之外也会为用户提供了足够的灵活空间存储应用数据，但是其中涉及到的对数据读擦写以及用户的应用程序均需要在外部 Flash 执行，这为 Flash 的操作带来了麻烦。        对于在XIP（eXecute-In-Place）模式下的应用，对Flash读擦写的操作需要在内部 RAM 里执行，而RT系列由于高主频而引入了内核 Dcache 以及 Flexspi 模块自带的 Pre-fetch 功能，对外部 Flash 的操作会有很多需要注意的地方，这些问题在带有 RTOS 的系统里则更是突显出来，而无论在 XIP 模式下的裸机还是基于 RTOS 方式对 Flash 的操作，SDK 里均没有提供例程可供参考。        本参考方案来自很多客户的实际应用需求，所以编写了基于 FreeRTOS 下的对片外 QSPI Flash 的读擦写操作，客户可以基于此例程移植到自己的应用里面做相关的应用开发，并配套对应的指导文档提醒用户在移植过程中需要注意的几个常见的 tips。 Products Product Category NXP Part Number URL MCU MIMXRT1021 i.MX RT1020 Crossover MCU with Arm® Cortex®-M7 core MCUXpresso SDK Software SDK v2.6.1 Welcome | MCUXpresso SDK Builder    Tools NXP Development Board URL MIMXRT1020-EVK MIMXRT1020-EVK: i.MX RT1020 Evaluation Kit

Introduction The FRWY LS1046A comes with the mikroBUS connector that enables the capability to connect different peripheral depending on the application's requirements. The mikroBUS intends to be used for prototyping purposes that facilitate the interconnection of several peripherals. The PN7120 I2C connection delivers a secure and trustworthy connection between both NXP products. Overview The following demo belongs to examples of different usages of the LS1046A MPU, these demonstrations will soon be part of the LSDK. This document showcase the NFC capability to provide an additional layer of security to any access area. NFC access points authorize people with a registered RFID tag to grant access to a particular area. In case the RFID tag isn’t registered or authorized, the access is restricted. The system should alert the denied access to a supervisor in order to take action. The video below shows two NFC applications that can be implemented in the LS1046A, by connecting the Mikroe-2395 module based on the NXP PN7120. This demonstration allows registering new users by entering sensitive data into a local database. The second application validates an NFC tag by comparing the tag ID, with the ones previously registered in the database. The user can access the applications using the LAN with another device like a tablet, this allows the database to be in a non-easy access location for security purposes.

Overview Home broadband access is undergoing the biggest change since the advent of low-cost fiber. Millimeter-wave (mmWave) radio technology is bringing fiber-like speeds without the cost of digging up consumers’ yards to lay new cables. The problems associated with mmWave signal propagation have been mitigated with massive MIMO and signal processing, techniques that NXP’s Airfast modules and Layerscape Access processors have helped enable. However, as with fiber access, the challenge of bringing the broadband connection indoors has remained. The existing approach is to have a technician visit the site and route cabling and possibly power to outdoors, incurring cost, inconveniencing customers, and potentially damaging property. At the 2020 Consumer Electronics Show, NXP demonstrated how its contactless power and connectivity technology overcomes this challenge. NXP’s wireless power technology efficiently transmits power through a window—one made of low-E glass, no less—from a small indoor unit mounted on the window to a corresponding outdoor unit. The same units also transmit broadband data at gigabit speeds using NXP’s wireless data-link technology based on a Layerscape Access programmable baseband processor. This innovative through-glass approach overcomes a practical and economic challenge of internet service providers and helps enhance customer satisfaction.

Description Earlier this year NXP organized a promotional opportunity for amateur radio enthusiasts to use their creativity and build their own power amplifier designs. NXP received numerous creative submissions in this competitive Homebrew RF Design Challenge. We appreciate the dedication and enthusiasm from the community that made this contest a success. First place winner An MRF101AN broadband amplifier design with 1 W Input, 100 W Output 1.8-54 MHZ Amplifier deck. (For more information visit:NXP MRF-101 - RFPowerTools )  It is an amplifier with a bandwidth of 1.8MHz to 54MHz. Maximum output power of 100W up to 30MHz and 70W up to 50MHz. Maximum power supply 50V to 4A, with a Voltage Standing Wave Ratio of 1.5:1 maximum. The design dimensions of the PCB is 5x5 cm (2x2 in). and 310g weight including fan and heat sink. Second place winner A 600W broadband HF amplifier using affordable LDMOS devices (For more information visit: https://qrpblog.com/2019/10/a-600w-broadband-hf-amplifier-using-affordable-ldmos-devices/  ) This project is meant to demonstrate the capabilities of the MRF300 transistors as linear broadband devices in the 2-50MHz range and to be used by radio amateurs as a starting point for a medium-high power amplifier. This is also my entry to the NXP Homebrew RF Design Challenge 2019. To achieve the target of 600W output while also minimizing the level of even-number harmonics, a “push-pull” configuration of two transistors is used. Luckily, the manufacturer made it easy to design the PCB layout for such a thing by offering two versions (the MRF300AN & MRF300BN) that have mirrored pinout. The common TO-247 package is used, with the source connected to the tab. Each individual MRF300 LDMOS transistor is specified at 330W output over a 1.8-250MHz working frequency range, a maximum 28dB of gain and over 70% efficiency. The recommended supply range is 30-50Vdc. By studying the specifications, it looks like with correct broadband matching and some operational safety margin we can get close to 600W output at a voltage of around 45V across a resonably large bandwidth; the aim is to cover 1.8 to 54MHz. Main challenges when designing this amplifier are related to achieving good input and output matching over the entire frequency range as well as maintaining high and flat gain. Good linearity and a low level of harmonic products are mandatory. As the TO-247 is not a package specifically designed for high-power RF, there are some challenges with thermal design and PCB layout as well. Information taken from the essay by the winner. Third place winner A High Efficiency Switchmode RF Amplifier using a MRF101AN LDMOS Device for a CubeSat Plasma Thruster (For more information visit: Research - SuperLab@Stanford ) The Class E amplifier utilizes the active device as a switch, operating in only cutoff (off) and saturated (on) conditions. This minimizes the overlap of voltage and current, reducing losses in the active device. To further reduce loss the Class E amplifier utilizes an inductively tuned resonant network to achieve zero voltage switching, bringing the voltage across the switch to zero before turn on, eliminating energy stored in the output capacitance of the active device that would otherwise be dissipated. This is achieved with an inductively tuned series resonant output filter.  In the Class E amplifier losses are almost entirely determined by the current conducted by the active device so a high drain impedance is desired to maximize efficiency. The drain impedance is ultimately limited by the voltage rating of the switch. For our desired output power of 40W and the maximum voltage rating of 133V for the MRF101AN this impedance is still less than 50 ohms, so a L match circuit is used to match the drain impedance to 50 ohms. The load network in our design provides a drain impedance of 15.4+12.8j. As the MRF101AN will operate in saturation a high drive level is desired. To eliminate the need for a preamplifier and allow for digital control, we use a high speed gate drive chip typically used in switch-mode power supplies, LMG1020, to drive the MRF101AN instead of a RF preamplifier. A resonant network is used to provide voltage gain at the fundamental and third harmonic, providing a quasi-square wave on the gate which helps insure the device remains in saturation. Conclusion It was a close call and highly competitive! Each participant had their own creative, unique and impressive way of displaying the capabilities of these new parts. NXP is always up for new design challenges. Ready for the next challenge?
