32-BIT LED DRIVER WITH SHIFT REGISTER AND LATCH REJ03F0263-0100 Rev. 1.00 Jan. 24. 2008 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 24m A (Vcc=5.0V case) output current to drive anode mon 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 plete CMOS, power consumption can be greatly reduced when pared 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 mon LED drive - VCC 5V or 3.3V single power supply - High output current: All parallel outputs Q1~Q32 IOL=24m A (at VCC=5.0V), IOL=12m A (at VCC=3.3V), LEDs can be turned on simultaneously. - Low power dissipation: 200u W/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=-40o C~+85o C) - Pin configuration for easy layout on PCB. (Pin configuration allows easy cascade connection or LED connection) APPLICATION - LED array drive, The various LED display modules - PPC, Printer, VCR, Mini-po, Button-Telephone etc. All of LED display equipments BLOCK DIAGRAM LOGIC DIAGRAM Q1 2 PARALLEL DATA OUTPUTS SERIAL DATA OUTPUT Q2 Q3 Q4 Q29 Q30 Q31 Q32 20 21 22...
