SANYO will be listed on the mobile phone with LED driver IC, support 17 x 7 dot matrix composition

SANYO semiconductor announced the development of a 17 x 7 dot matrix mobile phone lighting with LED drive IC "LV5230BG", and will start the sample supply. 17 * 7 dot matrix is recommended for mobile phone clock display and other components of the LED. The IC integrates a (17 bit) channel driver circuit with a line side (Column, positive) driver for the P channel, and a driver circuit for a n channel driver for a terminal (Row). Mass production will begin in May 2010, the scale of production is 1 million per month.

The IC can be supplied to a maximum current of LED 25mA. The company said, "as the lighting uses brightness enough". The number of gray levels can be displayed as 64, the maximum number of gray levels can be displayed at the same time is 8. By changing the duty cycle (PWMDUTY) of the PWM (pulse width modulation) signal to display gray scale. Each LED can be used to display grayscale can be used as the "Palette" function settings. The number of the palette is 1 ~ 7, can be selected from the display of the gray level in the selection of the 7 gray level, and the support of the PWMDUTY value of each gray scale assigned to each palette number. It is also possible to drive the LED with the desired gray scale by specifying the palette number on the frame memory that supports the 17 x 7 of the LED. Also, the PWMDUTY value of the other gray scale is zero, which means that it can be displayed in black. The company said, the introduction of the palette function, the performance of the performance without loss of color, the required storage capacity is reduced to a minimum".

The maximum rated voltage is 5.5V. There is a I2C interface for setting the color palette. The package is installed with an area of 5mm * 5mm 49 terminal FBGA. Sample price of 300 yen.
