Philips Semiconductors Product specification LCD drivers 1 PCF21xxC family FEATURES 2 • Supply voltage 2.25 to 6.0 V GENERAL DESCRIPTION The PCF21xxC family are single-chip, silicon gate CMOS LCD driver circuits. A 3-line bus (CBUS) structure enables serial data transfer with microcontrollers. All inputs are CMOS/NMOS compatible. • Low current consumption • Serial data input • CBUS control The devices have the same function and performance as those of the PCF21xx family, which they supersede.

Philips Semiconductors Product specification LCD drivers 7 PCF21xxC family FUNCTIONAL DESCRIPTION 7.3 An LCD segment or LED output is activated when the corresponding DATA bit is HIGH. 7.1 When DATA bit 33 is HIGH, the latches are loaded. CLB pulse 35 transfers data from the shift register to the selected latches. PCF2100C 7.4 When DATA bit 21 is HIGH, the A-latches (BP1) are loaded. With DATA bit 21 LOW, the B-latches (BP2) are loaded.

Philips Semiconductors Product specification LCD drivers PCF21xxC family Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 °C. 13 SOLDERING 13.1 Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board.
