Achieve the perfect balance of speed, efficiency, and data density with MB85AS8MT and STM32F302VC

ReRAM 2 Click is based on the MB85AS8MT, a highly reliable 8Mbit resistive random-access memory (ReRAM) organized as 1,048,576 words of 8 bits from Fujitsu Semiconductor. It uses the resistance-variable memory process and silicon-gate CMOS process technologies to form nonvolatile memory cells. The MB85AS8MT specifies 1.000.000 endurance cycles with data retention of a minimum of 10 years, which gives the MB85AS8MT the capability to handle unlimited reads/writes to the memory. One prominent feature of the MB85AS8MT is an extremely small average current, despite its large density, for reading operations of 0.15mA at an operating frequency of 5MHz, which is only 5% of

large-density EEPROM devices. This feature enables minimal power consumption when in applications with frequent data-read operations. Besides higher write endurance, it has faster write speeds than EEPROM and flash memory, while its electric specifications, such as commands and timings, are compatible with EEPROM products. The ReRAM 2 Click communicates with MCU through a standard SPI interface that enables high clock speeds up to 10MHz, supporting the two most common SPI modes, SPI Mode 0 and 3. An additional feature of this Click board™ represents the configurable Write Protection function labeled as WP routed on the PWM pin of the mikroBUS™ socket. The WP pin protects the entire memory

and all registers from write operations and must be set to a low logic state to inhibit all the write operations. All memory and register write are prohibited when this pin is low, and the address counter is not incremented. Besides, the ReRAM 2 Click also has an additional HOLD pin, routed to the RST pin of the mikroBUS™ socket labeled as HO, to interrupt a serial operation without aborting it. This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Clicker 4 for STM32F3 is a compact development board designed as a complete solution, you can use it to quickly build your own gadgets with unique functionalities. Featuring a STM32F302VCT6, four mikroBUS™ sockets for Click boards™ connectivity, power managment, and more, it represents a perfect solution for the rapid development of many different types of applications. At its core, there is a STM32F302VCT6 MCU, a powerful microcontroller by STMicroelectronics, based on the high-

performance Arm® Cortex®-M4 32-bit processor core operating at up to 168 MHz frequency. It provides sufficient processing power for the most demanding tasks, allowing Clicker 4 to adapt to any specific application requirements. Besides two 1x20 pin headers, four improved mikroBUS™ sockets represent the most distinctive connectivity feature, allowing access to a huge base of Click boards™, growing on a daily basis. Each section of Clicker 4 is clearly marked, offering an intuitive and clean interface. This makes working with the development

board much simpler and thus, faster. The usability of Clicker 4 doesn’t end with its ability to accelerate the prototyping and application development stages: it is designed as a complete solution which can be implemented directly into any project, with no additional hardware modifications required. Four mounting holes [4.2mm/0.165”] at all four corners allow simple installation by using mounting screws. For most applications, a nice stylish casing is all that is needed to turn the Clicker 4 development board into a fully functional, custom design.
