TB62709N
Intelligent, Constant Current, 7 segment LED numeric display
decoder/driver. For use with common anode configuration
numeric displays.
The TB62709N/F is an intelligent Constant Current LED display
driver designed specifically for seven segment LED display applications. The stand alone device includes all of the decode,
multiplex and driver circuitry necessary to control up to four seven
segment LED digits. All of the information required to program
up to four LED digits is input serially including a 16 step brightness control. Expansion beyond four digits is possible with a
cascade connection to a second device. The device automatically refreshes and maintains the displayed information.

Data Input
Data is input on the SERIAL-IN terminal. 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).

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.

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.

Brightness Control
Brightness is controlled by controlling the “on time” duty cycle. 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.

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.

Operation examples.
Example 1
Example 1 sets up the character a at Digit 0, b at Digit 1, c at Digit 2 and d at Digit 3. The
characters are initially set at full brightness (15/16 duty cycle) and displayed. The duty cycle is
then changed to half brightness (8/16 duty cycle) as the display is first blanked and then activated with the same a,b,c and d characters. The display is then flashed on and off by alternating
the BLANK and NORMAL commands before going to the STAND-BY Mode.

Operation examples.
Example 2
Example 2 sets up the character a with the decimal point on at Digit 0 at full brightness (15/16
duty cycle) with the remaining digits (1~3) left blank. The display then changes to a character b
with the decimal point on displayed at Digit 1 with Digits 0, 2 and 3 blank. Character c (decimal
point on) is then displayed at Digit 2 with Digits 0, 1 and 3 left blank and the sequence ends with
the character d (decimal point on) displayed on Digit 3 with Digits 0~2 left blank followed by the
STAND-BY Mode.
