MiWi click is a subgigahertz radio transceiver click board™, which offers a reliable FSK or OOK communication solution, with the maximum data rates of 40kbps and 16kbps, respectively. The radio transceiver module used on this click board™ has plenty of features that make it a perfect choice for compact designs: It has very good reception sensitivity, an onboard PCB antenna, high level of components integration, built in packet handling routines with automatic CRC generation, 64 bytes of transmit/receive FIFO buffer, built in Sync Word recognition, clock/data synchronisation and recovery and many more.

Armed with such a powerful, compact and fully configurable radio transceiver module, MiWi click offers highly reliable radio communication over a short distance, which can be utilized in many applications. It can be used for developing home/industrial/building automation applications, data loggers, applications for remote keyless access, alarms, wireless remote control and a wide variety of similar short-range radio applications.

MRAM click features MRAM module which contains 262,144 magnetoresistive memory cells, organized into 32,768 bytes of memory. It means that MRAM click is a memory storage device with 32KB of memory space. The used memory module can withstand an unlimited number of write cycles, it has data retention period greater than 20 years and it can read and write to random addresses with no delay.

Besides these features that already mark this kind of memory modules a milestone in memory manufacturing technology, the device features data protection in case of power loss, block write protection, low power consumption and fast SPI interface that can theoretically work up to 40MHz. Because of its universal memory characteristics, MRAM click can be used both as a non-volatile storage media, or temporary RAM expansion for storing variables in any embedded application.
