Excelon-Ultra Click Board™

Product Code: MIKROE-4698

How Does The Excelon-Ultra Click Board™ Work? The Excelon-Ultra Click Board™ as its foundation uses the CY15B116QSN, a high-performance 16-Mbit nonvolatile memory that employs an advanced ferroelectric process from Infineon. The memory array is logically organized as 2,097,152 × 8 bits and is accessed using an industry-standard serial peripheral interface (SPI) bus. The CY15B116QSN combines a 16-Mbit F-RAM with the high-speed Quad SPI SDR and DDR interfaces, enhancing FRAM technology's nonvolatile write capability. The key differences between the CY15B116QSN and a serial flash are the FRAM's superior write performance, high endurance, and lower power consumption. The CY15B116QSN is ideal for nonvolatile memory applications, requiring frequent or rapid writes. Examples range from data collection, where the number of write cycles may be critical, to demanding industrial controls where the long write time of serial Flash can cause data loss. The Excelon-Ultra Click Board™ communicates with MCU using an industry-standard SPI interface supporting the two most common modes, SPI Mode 0 and 3, with a maximum frequency of 108MHz.

Data is written to the memory array immediately after each byte is successfully transferred to the device. The following bus cycle can commence without the need for data polling. It supports 1e14 read/write cycles or 100 million times more write cycles than EEPROM. In addition, the CY15B116QSN offers substantial write endurance compared to other nonvolatile memories. Furthermore, this Click board™ provides additional hardware-controlled functions. The configurable Write Protection function, routed on the PWM pin of the mikroBUS™ socket, protects all registers (including status and configuration) from write operations when the SRWD bit (SR1[7]) is set to '1'. The WP pin must be held high to inhibit all the write operations to registers. When this pin is high, all memory and register writes are prohibited, and the address counter is not incremented. Also, it has a Reset feature routed to the RST pin on the mikroBUS™ socket, which puts the CY15B116QSN into a Reset state with a low logic level, and with a high level operates module normally. The Excelon-Ultra Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
