Hardware Overview
How does it work?
Semper Flash Click is based on the S25HS512T, a 512 Mbit SPI Flash memory module from Infineon. Featuring both normal and double data rates over the standard, Dual/Quad SPI interface, the improved reliability of the stored information by utilizing the hardware Error Correction Code (ECC) generation, One-Time Programmable (OTP) memory block of 1024 bytes, advanced sector protection, AutoBoot, and much more, this Click board™ is a perfect solution for the mass storage option in various embedded applications. Due to its fast performance, Semper Flash click can also be used for code shadowing, execute-in-place (XIP), data logging, and data storage. An additional level translator IC allows Semper Flash click to be used with a wide range of MCUs. The device control logic is subdivided into two parallel operating sections: the Host Interface Controller (HIC) and the Embedded Algorithm Controller (EAC). The HIC monitors signal levels on the device inputs and drives outputs to complete read, program and write data transfers with the host system. The HIC delivers data from the currently entered address map on read transfers, places write transfer address and data information into the EAC command memory and notifies the EAC of power transition and write transfers. The EAC interrogates the command memory after a program or writes transfer for legal command sequences and performs the related Embedded Algorithms. Executing code directly from Flash
memory is often called Execute-In-Place (XIP). By using XIP with Semper Flash devices at the higher clock rates with Quad or DDR Quad SPI transactions, the data transfer rate can match or exceed traditional parallel or asynchronous NOR flash memories while reducing signal count dramatically. The advanced MirrorBit® technology allows storing two data bits in each memory array transistor (memory cell), effectively doubling the capacity of a single storage cell. The Eclipse™ architecture is responsible for the greatly improved erase and programming performance, compared to other Flash modules of the previous generation. Due to a higher speed, an execute-in-place (XIP) and data shadowing is possible with the Semper Flash click. One of the S25HS512 T's key features is the AutoBoot feature. It allows the module to automatically initiate the memory transfer from the predefined location (memory read operation) after the reset cycle. Considering a typical communication scenario, where the READ command followed by one or more address bytes need to be used, AutoBoot allows the host MCU to pull down the #CS (Chip Select) pin and start receiving a data stream over the SPI interface for as long as the #CS pin is held LOW, without any wasted cycles. When the #CS pin is released, the S25HS512T returns to normal operation. Advanced Sector Protection (ASP) is a powerful protection model incorporating various software and hardware methods to turn programming on or off
or erase operations within a sector or an entire memory. A specialized ASP OTP register offers password protection or a persistent protection mode, allowing increased flexibility in the protection. Using the OTP memory allows the protection mode to remain in place for the whole life-cycle of the device. The SPI interface pins are routed to the mikroBUS™ so that the interfacing with the microcontroller unit (MCU) is easy and straightforward. Additional pins routed to the mikroBUS™ include the #WP/IO2 pin routed to the mikroBUS™ PWM pin and labeled as IO2 and the #HOLD/IO3 pin routed to the mikroBUS™ INT pin and labeled as IO3. There is also the RESET pin, routed to the RST pin of the mikroBUS™, which performs a reset of the Flash module, initiating an AutoBoot sequence if enabled. EnduraFlex Architecture allows system designers to customize the NOR Flash endurance and retention for their specific applications. The host defines partitions for high endurance or long retention, providing up to 1+ million cycles or 25 years of data retention. Data Integrity Check transactions in Semper Flash perform a hardware-accelerated Cyclic Redundancy Check (CRC) calculation over a user-defined address range in the memory array. The SafeBoot feature allows Status Register polling to detect an embedded microcontroller initialization failure or configuration register corruption through error signatures.

*
* # Description
* This example showcases how to initialize and use the Semper Flash Click. The Click
* is a 512 Mbit SPI Flash memory module. Data can be stored in and read from the flash
* memory. There's also the option of erasing it's contents. Here's how to do it.
*
* The demo application is composed of two sections :
*
* ## Application Init
* This function initializes and configures the Click and logger modules. Additional con-
* figuring is done in the default_cfg(...) function. The device ID should appear in the
* UART console if the setup finishes successfully.
*
* ## Application Task
* This function first erases the contents of the flash memory and then writes, reads and
* prints two strings in the UART console. It does so every 2 seconds.
