... The TB62779FNG is controlled using the DATA and CLK input signals slave IDs (slave addresses) can be independently assigned to the TB62779FNG. Fabricated using the Bi-CMOS process, the TB62779FNG is capable of high-speed data transfers. The TB62779FNG operates with a supply voltage of 3 The TB62779FNG is RoHS (2002/95/EL) compliant. 1.

... Programming the TB62779FNG The TB62779FNG can be programmed by the DATA signal on the SDA pin (pin 2) and CLK signal on the SCK pin (pin 3). Though the specification of these signal lines is similar to that of the I2C bus, these lines are only used to program data to the TB62779FNG and bi-directional data transfers are not performed. The TB62779FNG should basically be programmed using one of the following formats: (1) Serial Packet Format in Normal Programming Mode or (2) Serial Packet Format in Special Mode 1 ...

... The SDA signal must be changed when SCLK is Low. SDA SCLK DATA must not be changed. 5) Acknowledge CLK signals for acknowledgement must be generated after every byte received. (Though the TB62779FNG is not designed to perform bi-directional data transfers, it must generate this acknowledgement clock signal.) SDA SCL S DATA can be changed. ...

... Power-ON Reset (POR) The POR circuitry resets all the internal data to the default values upon powering up the TB62779FNG in order to ensure proper device operation. The POR circuitry is only activated when Vcc rises from reactivate POR, Vcc must be powered down The internal data hold voltage is guaranteed after Vcc has once reached or exceeded 3.0 V. ...

... The total resistance value of three external resistors used for specifying a device ID (which are connected between Vcc and GND) should be about 30 kΩ or lower. (A recommended value will be clearly defined after the TB62779FNG is completed configuration sequence ID configuration can be performed after POR is released upon powering on. However, to avoid false operation of the ID configuration, transient input signals of less than two clock cycles of the reference clock for the internal oscillator are not accepted ...
