8-bit USB flash microcontroller reduces the number of application power supply circuits, simplifies design
April 19, 2011 // Paul Buckley
SANYO Semiconductor Co., Ltd., has introduced a new 8-bit flash microcontroller with USB 2.0 Full-Speed interface function and built-in DC-DC converter (step-up/step-down circuit) with selectable output voltages. The LC87F1864A device provides a solution that supports stable power supply, space efficient and cost effective designs in USB card reader products, such as integrated circuit (IC) cards.
The step-up circuit (charge pump) and step-down circuits (series regulator) incorporated in the LC87F1864A drive output voltage values of 5.0 V, 3.0 V and 1.8 V, or the alteration of output voltage settings via an external resistor, thus enabling stable power supply to peripheral devices. With the addition of a Universal Asynchronous Receiver Transmitter (UART), the IC cards interface is fully compliant with ISO7816-3 standards. In addition to a wide variety of USB card reader products, the USB feature enables various types of data held on the IC card to be transmitted via USB to personal computers.
Housed in a SQFP48 package measuring 7 mm x 7 mm, the LC87F1864A device incorporates an on-chip debugger function, a 16-bit timer / counter (divisible by 8-bit timer with 8-bit pulse width modulation (PWM) possible), 64 KB read only memory (ROM) and 2 KB of random access memory (RAM).
Sample shipping of the LC87F1864A 8-bit USB flash microcontroller will commence from April 2011.
