el Pr im in y ar
56-Bit Duplex/Triplex (1/2 duty / 1/3 duty) VF Controller/Driver with Digital Dimming
The ML9211 is a full CMOS controller/driver for Duplex or Triplex (1/2 duty or 1/3 duty) vacuum fluorescent display tube. It consists of a 56-segment driver multiplexed to drive up to 168 segments, and 10-bit digital dimming circuit. ML9211 features a selection of a master mode and a slave mode, and therefore it can be used to expand segments for the VFD driver with keyscan and A/D converter function. ML9211 provides an interface with a microcontroller only by three signal lines: DATA IN, CLOCK and CS.

FUNCTIONAL DESCRIPTION
Power-on Reset When power is turned on, the ML9211 is initialized by the internal power-on reset circuit. The status of the internal circuit after initialization is as follows: * The contents of the shift registers and latches are set to "0". * The digital dimming duty cycle is set to "0". * All segment outputs are set to Low level. * All grid outputs are set to High level. Data Transfer Method Data can be transferred between the rising edge and the next falling edge of chip select input. The mode data, segment data and dimming data are written by a serial transfer method. The serial data is input to the shift register at the rising edge of a shift clock pulse. The mode data (M0 to M2) must be transferred after the segment data and dimming data succeedingly. When the chip select input falls, an internal LOAD signal is automatically generated and data is loaded to the latches. Function Mode Function mode is selected by the mode data (M0 to M2). The relation between function mode and mode data is as follows:
FUNCTION MODE 0 1 2 3 4 OPERATING MODE Segment Data for GRID1-3 Input Segment Data for GRID1 Input Segment Data for GRID2 Input Segment Data for GRID3 Input Digital Dimming Data Input FUNCTION DATA M0 0 1 0 1 0 M1 0 0 1 1 0 M2 0 0 0 0 1
Segment Data Input [Function Mode: 0 to 3] * ML9211 receives the segment data when function mode 0 to 3 are selected. * The same segment data is transferred to the 3 segment data latches corresponding to GRID 1 to 3 at the same time when the function mode 0 is selected. * The segment data is transferred to only one segment data latch corresponding to the specified GRID when the function mode is 1, 2 or 3 is selected. * Segment output (SEG1 to 56) becomes High level (lighting) when the segment data (S1 to S56) is set to "1".

Digital Dimming Data Input [Function Mode: 4] * ML9211 receives the digital dimming data when function mode 4 is selected. * The output duty changes in the range of 0/1024 (0%) to 1016/1024 (99.2%) for each grid. * The 10-bit digital dimming data is input from LSB.

Master Mode Master Mode is selected when M/S pin is set at High level. The master mode operation is as follows: * The input levels of DIM IN, SYNC IN1 and SYNC IN2 are ignored, and these pins should be connected to L-GND or VDD. * Brightness is adjusted by the internal digital dimming circuit. * The segment Latch1 to 3 corresponding to GRID1 to 3 are selected by the internal timing generator.

Slave Mode Slave Mode is selected when M/S pin is set at Low level. The slave mode operation is as follows: * The internal dimming circuit is ignored. * The pulse width of SEG1 to 56 are controlled by the pulse width of DIM IN signal. * The segment Latch1 to 3 corresponding to GRID1 to 3 are selected by SYNC IN1 and SYNC IN2 signals. * The output levels of GRID1 to 3 are set at High level. The output levels of DIM OUT, SYNC OUT1 and SYNC OUT2 are set at Low level.

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
