NEC expands MCU portfolio
NEC Electronics America Inc. has announced the expansion of its 8bit 78K0S/Kx1+ microcontroller (MCU) series to include 10 devices that complement the company's all flash portfolio and provide seamless coverage of system requirements for multiple MCU applications.
These three 10-pin 78K0S/KU1+ MCUs are available in a package in a plastic shrink small-outline package (SSOP) that measures 4.4-by-3.72mm. The company is also adding to its existing low-pin-count series devices seven new 78K0S/KB1+, 78K0S/KA1+ and 78K0S/KY1+ MCUs that are available with pin counts ranging from 16 to 30 and on-chip flash memory ranging from 1-8KB.
With small form factors, fine-grained on/off control and high reliability, all 10 of the MCUs are ideally suited for cost-sensitive white goods applications that require only on/off sequence control services, for example vacuum cleaners, refrigerators, coffee makers, microwave ovens, electric tools, smoke detectors, light-emitting diodes (LEDs), heaters, motors and pumps.
The 10-pin 78K0S/KU1+ MCUs have flash memory capacities ranging from 1-4KB. Designers using these devices can reduce on-board footprints by about 30 per cent compared to footprints housing current 16-pin packages, thereby reducing the size, weight and cost of final products.
Available in a variety of pin counts and memory sizes, the seven 78K0S/KB1+, 78K0S/KA1+ and 78K0S/KY1+ MCUs have low-cost semiconductor switching functions that can be used as replacements for dedicated switches to reduce the size and weight of switching control and data transfer mechanisms. The devices also offer finer-grained on/off control and higher reliability.
The 30-pin 78K0S/KB1+ MCUs feature 4KB and 8KB of flash memory, the 20-pin 78K0S/KA1+ MCUs 2KB to 4KB, and the 16-pin 78K0S/KY1+ MCUs have 1-, 2- and 4kB. The omission of an A/D converter in these seven devices allows designers to select only the functions they need, making these MCUs a cost-effective choice for applications in which analogue data (such as temperature or weight data obtained from sensors) need not be converted into digital data by the MCU.
