TOSHIBA Bi−CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC

TB62709N,TB62709F

7−SEGMENT DRIVERS WITH BUILT−IN DECODERS

(COMMON ANODE CAPABILITY, MAXIMUM 4−DIGIT CONTROL)

The TB62709N and TB62709F are multifunctional, compact,

7−segment LED display drivers.

These ICs can directly drive 7−segment displays and individual

LEDs, and can control either a 4−digit display with decimal

points, or 32 individual LEDs.

These ICs can also be used with common−anode displays. Their

outputs are constant current, the ampere levels at which are set

using an external resistor.

A synchronous serial port connects the IC to the CPU.

The different modes of control provided by this device including

Duty Control Register Set, Digit Set, Decode Set and Standby Set,

are all based on every 16−bit of serial data.

TB62709N/F

DESCRIPTION OF OPERATION

Data input (SERIAL−IN, CLOCK, LOAD)

The data are input serially using the SERIAL−IN pin. The data input interface consists of a total of three

inputs : SERIAL−IN, LOAD, and CLOCK.

Binary code stored in the 16−bit shift register offers control modes including duty Control Register Set, Digitset,

Decode Set, and Standby Set,

The data are shifted on the rising edge of the clock, starting from the MSB. Cascade−connecting TB62709N or

TB62709F devices provides capability for controlling a larger number of digits.

The serial data in the 16−bit shift register are used as follows : the four bits D

(MSB) to D

select the IC

operating mode (Table 1), while D11 to D

select the register corresponding to the operating mode (Table 2).

Bits D

to D

(LSB) of the 16−bit shift register are used for detail settings, such as number of digits in use,

character settings in each digit, and light intensity.

The internal registers are loaded on the rising edge of the LOAD signal, which causes loading of data from an

external source into the D

(MSB) to D8 bits of the shift register, operating mode and the corresponding

to D0 (LSB) are loaded.

Normally LOAD is Low. After a serial transfer of 16bits, the input of a High−level pulse loads the data.

Note the following caution : Use the D

to D

setting and the D

to D

detail data setting as a pair. If only the

to D

data are input without setting D

to D

an error condition may result, in which the device will not

operate normally. If the current mode is set again by a new signal, the data for D

to D

must also be re−input.

Operating precautions

At power−on or after operation in Clear mode (in initial state), set the IC to Normal mode again. Otherwise, the

IC will not drive the LED.

Operating the IC in Blank mode (all lights off) or in All On mode (all lights lit) does not affect the internal data.

Setting the IC to Normal mode again continues the LED lighting in the state governed by the settings made

immediately before mode change.

Normal mode (not Shut Down, Clear, Blank, or All On mode) continues the operations set in Load Register

mode. In Normal mode, operations are governed by any new settings made in the Load Register, as soon as the

changed setting values are loaded.
