Each 16 bit serial word includes an address (D15 ~ D8) and data (D7 ~ D0). A low to high transition load command on the LOAD terminal loads the data into the appropriate registers following the 16th clock pulse. Operation Serial data is input on the DATA-IN terminal beginning with the most significant bit (MSB). Data is clocked through the 16 bit shift register on the rising edge of the clock. A Low to High transition on the LOAD input following the 16th (LSB) bit latches the 16 bit word into the 16 bit D-type latch. Expansion beyond four digits is possible through the use of a cascade connection from the DATA-OUT terminal. The data-out lags data-in by one bit through the data-out terminal. Each 16 bit word typically includes 8 address bits and 8 data bits. The first four data bits, beginning with D15 (MSB) ~ D12 select the Action mode (see figure 1). These global commands determine the overall function the device is to perform and includes Blank, Normal Operation, Load Register, All On and Stand-by. Data bits D11~D8 select the particular register to be loaded (see figure 2) should the load register function be selected. Data bits D7~D0 (LSB) define the specific commands required to program the display and define the brightness setting (duty cycle). Figure 1.

TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB62709N/F Action Mode 1. Blank - Constant current segment drivers are off resulting in an all segments off condition. Data D15 ~ D12 are 0. D11~D0 are not relevent in blank mode. 2. Normal (Operation) - Instructs device to display data loaded during previous steps. D11~ D0 are not relevent in the Normal Operation mode. 3. Load Register - Directs the device to recognize and load D11~ D0. In this mode D11 ~ D8 determines the specific register to be loaded (see figure 2) and D7 ~ D0 serves as the actual data to be loaded for programming the brightness (duty cycle) or the particular digit. 4. All On - All constant current segment drivers are on resulting in an all segments illuminated condition. D11 ~ D0 are not relevent in this mode. 5. Stand By - All display segments off condition. The Stand-By command turns off all internal bias currents and serves as a low power consumption mode (<.2mA). Used with Stand-By set up commands “All Data Clear” or “Data Not Cleared” (table 7). The initial state, upon power up, is the BLANK state. Application Note: Stand-By and Blank perform similar functions in that the display is totally blank when either command is input. Stand-By provides a low power consumption (<.2ma current draw on VDD) mode by turning off all internal bias currents in the internal driver circuits. The Stand-By command also cuts off the Rext bias current used to regulate the programmed constant current within the device. marktech optoelectronics For up-to-date product info visit our web site at www.marktechopto.com 120 Broadway • Menands, New York 12204 Toll Free: (800) 98-4LEDS • Fax: (518) 432-7454 All specifications subject to change. 591 TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB62709N/F LOAD REGISTER Mode Figure 2.

TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB62709N/F Data Decode The TB62709F utilizes two basic modes of operation. In the DECODE MODE, data encoded in data bits D7~D0 is decoded to display preset characters per table 8. This mode is activated as illustrated in table 5. With D15~D8 programmed as 21 Hex and D7~D4 as 1 Hex the DECODE MODE is selected. In the DIRECT DRIVE MODE the ability to decode data to preset characters for display is bypassed giving the programmer direct control of the 8 constant current sink outputs. This mode may be used to drive discrete LEDs or to display characters not included in the character set.

This programming step is performed simultaneously with the DIGIT SELECTION decision (table 4) which utilizes D3~D0.The initial state, upon power up, is the DECODE mode.

The device allows for 16 brightness steps as illustrated in list 3 with 0/16 as the dimmest setting (not illuminated) to 15/16 as the brightest setting. The duty cycle control register is addressed with a 20 Hex command at D15~D8 and the appropriate data per list 3 at D3~D0. D7~D4 are not recognized by the duty cycle register. The initial state, upon power up is 15/16, or full brightness.

TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB62709N/F Digit Selection The digit(s) to be programmed are selected as illustrated table below. This function is enabled with a 21 Hex command at D15~D8 and the appropriate data sequence to select Digit 0 only, Digit 0 and 1, Digit 0 -2 or digit 0-3 as illustrated in table 4.

D11~D4 are not relevent in the STAND-BY / NO DATA CLEAR Mode. STAND-BY / DATA CLEAR also places the device in a power save mode and clears data in the various registers leaving registers in their initial state.

This mode is enabled along with the LOAD REGISTER Mode (See LOAD REGISTER Mode section - Figure 2). A 2 Hex command at D15~D12 selects the LOAD REGISTER Mode. The specific register to be addressed is selected by D11~D8. The digits are designated D0, D1, D2 and D3 and are addressed per their respective registers as illustrated in Figure 2. D3~D0 provides the code for the seven segment display. D5 and D4 select one of two character sets and D6 controls the decimal point for each digit. marktech optoelectronics For up-to-date product info visit our web site at www.marktechopto.com 596 120 Broadway • Menands, New York 12204 Toll Free: (800) 98-4LEDS • Fax: (518) 432-7454 All specifications subject to change.
