Four multi-function gates from Diodes have user-customised logic configurations so that a single part can replace multiple devices. They provide space and weight saving in space-constrained applications such as fitness wearables, smartphones and other portable consumer electronic devices. The power consumption means that they can also be used in consumer products, such as tablets, e-readers, MP3 players, hand-held games and GPS devices.
The 74AUP1G57, 74AUP1G58, 74AUP1G97 and 74AUP1G98 provide various base gate arrangements with three inputs and one output, from which the user can configure the required logic function: AND, OR, NAND, NOR, XOR, XNOR or MUX.
Wearable
Multiple microcontrollers have core-independent peripherals
Two 8bit families have been added to the PIC MCUs from Microchip. They have core-independent peripherals which can be interconnected to combine and perform functions autonomously, without the core.
Small package SPI FRAM suits power-critical wearable designs
An 8pin, WL-CSP has been added as an additional package variant for the MB85RS1MT, 1Mbit SPI FRAM from Fujitus.
According to the company, the package, measuring 3.09 x 2.28 x 0.33mm, reduces the surface area, compared with the industry standard SOP-8 package, reduces the surface mounting area by 77%, and the device height by 80%. It is, claims the company, a 1Mbit SPI FRAM product with the industry’s smallest packaging technology.
The WL-CSP package makes FRAM applicable for wearable and sensor designs, which require small device dimensions, extremely low power consumption for maximum battery lifetime, and high endurance in write cycles in case of real time logging.
Conventional non-volatile memories like EEPROM or Flash memory cover an endurance of one million write cycles, whereas the MB85RS1MT FRAM provides an endurance of 10 trillion read/write cycles, allowing flexible storage of real time logging data. Unlike the block access of EEPROM and Flash, FRAM can be overwritten fast and flexibly into each memory cell without any waiting time, points out the company. As a result, it consumes lower energy in the writing access, and contributes a great deal to extend the battery lifetime, especially for wearable / sensor applications with frequent logging functions.
The MB85RS1MT device operates in the voltage range of 1.8 to 3.6V and guarantees a data retention of 10 years at 85°C. The operation temperature ranges from -40°C to 85°C.
The device is being offered in SOP-8 and 8pin WL-CSP packages.
