Device integrates DC-DC converter and interface function, reducing the number of application power supply circuits and simplifying design

GUNMA, Japan – April 19, 2011 (JST) – SANYO Semiconductor Co., Ltd. (an ON Semiconductor company) today announced the introduction of 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 volts (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.

“The LC87F1864A incorporates a highly versatile DC-DC converter, allowing for selection of step-up/step-down statuses and selection of output voltages,” said Hideo Kondo, general manager of SANYO Semiconductor's Micon Development Department. “Incorporating the DC-DC converter feature, which is normally used as an external IC, into the microcontroller minimizes the circuit-board areas, reduces costs for end-products, and controls the output voltage through an ON/OFF switch.”

Pricing and Availability
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. The device is budgetary priced at $3.00 per unit in quantities of 10,000 units.
