REJ03F0263-0100 Rev. 1.00 Jan. 24. 2008 R8A66162SP 32-BIT LED DRIVER WITH SHIFT REGISTER AND LATCH DESCRIPTION The R8A66162SP is a semiconductor integrated circuit for LED array driver with 32-bit serial-input, parallel output shift register, equipped with direct set input and output latches. The R8A66162SP guarantees sufficient 24mA (Vcc=5.0V case) output current to drive anode common LED, allowing 32-bit simultaneous and continuous current output. The parallel outputs are open-drain outputs. In addition, as this product has been designed in complete CMOS, power consumption can be greatly reduced when compared with conventional BIPOLAR or Bi-CMOS products. Furthermore, pin layout ensures the realization of an easy printed circuit. R8A66162SP is the succession product of M66313FP. FEATURES Anode common LED drive VCC 5V or 3.3V single power supply High output current: All parallel outputs Q1~Q32 IOL=24mA (at VCC=5.0V), IOL=12mA (at VCC=3.3V), LEDs can be turned on simultaneously. Low power dissipation: 200uW/package (max) (VCC=5.0V, Ta=25OC, quiescent state) High noise margin: Employment of Schmitt-trigger circuit on all inputs allows application with long wiring. Direct set input (SD) Open-drain output (Q1~Q32) Serial data output for cascading (SQ32) Wide operating temperature range (Ta=-40oC~+85oC) Pin configuration for easy layout on PCB.

Each shift register bit consists of a flip-flop for shifting and an output latch. The shift operation takes place when the shift clock input CK changes from low-level to high-level. The serial data input A corresponds to the data input of the first-stage shift register, and the shift register is shifted in sequence when a pulse is applied to CK. If the latch-enable input LE is turned high-level, the content of the shift register at that instant is latched. The parallel data outputs Q1~Q32 are open-drain outputs. To expand the number of bits, use the serial data output SQ32 which shows the output of the shift register of the 32nd bit. If the direct set input SD is turned low-level, Q1~Q32 and SQ32 are set. Then shift register and latches are set. If the high-level input is applied to the output enable input OE, Q1~Q32 are set to the high-impedance state, but SQ32 is not set to the high-impedance state. The shift operation is not affected when OE is changed.
