The New Microchip PIC16F15386 Microcontroller Line Includes 13 Models

The Microchip Technology Co. has presented a new family of eight-bit PIC microcontrollers with core-independent peripherals. Among common features of these models one can highlight the presence of the internal frequency generator (32 MHz) and the memory boot partition security mechanism meant for protection from the faulty rerecording. Moreover, there is a secure device information area (DIA) storing the device unique identifier and calibration constants. The just-launched controllers are supported by the Microchip MPLAB Xpress with MPLAB Code Configurator (MCC) framework.



This line of products offers 13 samples possessing 2 Kbyte of RAM and up to 28 Kbyte of onboard flash. The specialties are incorporated into PDIP, SOIC, DFN, UDFN, UQFN and SSOP cases with an 8–48 pin count. The number of ADC and I/O channels has increased.


Presentation samples as well as stock-produced items are already available. Wholesale prices start with $0.33 per unit.

An All-new Series of Super Flower Power Supply Units Is Introduced by 10 Devices of 400–850 W Capacity

The Super Flower Co. is widely known by virtue of its 80Plus Titanium power modules. At present this manufacturer is going to present a cutting-edge series of low-profile devices.



The latest line will include ten power supplies, the capacity of which varies in the range of 400–850 W depending on the model. Those of them providing 750 W and more will get partially detachable cables.


Being optimized by Super Flower professionals, the topological layout of these Super Flower products is based on the two-transistor forward converter. PWM and PFC schemes are designed with a Fairchild controller and Infineon field-effect transistors. Hardware components also incorporate STMicroelectronics and Mospec diodes, a Fujitsu relay and a Teapo electrolytic capacitor.


All models of this series are intended for Super Flower OEM customers and comply with 80Plus Bronze standards.

Rosewill Introduces PSU Line of 80 Plus Platinum Standards

Rosewill, Californian hardware manufacturer, has gladdened its potential customers with a new PSU line codenamed Fortress. The major peculiarity of this line is that all products are characterized by rather high efficiency coefficient: up to 94% in 230 V alternating current networks. The new line involves models of 450W, 550W, 650W, and 750W showings which have already received 80 Plus Platinum certificate.



Low power dissipation is achieved exactly due to the high efficiency which reduces ventilation demands immensely. The employment of 135 mm fans provided for the perceptible decreased of noise. Those features are considered to be the basic attraction for the customers.


All four models in Fortress line are developed according to a similar scheme with a single 12 V bus. The chief differentiation between the models lies in the output capacity and a cable set. Hence, the high-order PSU is capable to give current of up to 62.5 A; in the aggregate with the available 4 …
