CMOS IC
LC723461W, 723462W
Ultralow-Voltage ETR Controller with On-Chip LCD Driver
Preliminary Overview
The LC723461W and LC723462W are ultralow-voltage electronic tuning microcontrollers that include a PLL that operates up to 250 MHz and a 1/4 duty 1/2 bias LCD driver on chip. This IC includes an on-chip DC-DC converter that can easily create the power supply voltages needed for electronic tuning and contribute to reducing end product costs. This IC is optimal for portable audio equipment that must operate from a single battery. • • • switched for use as serial I/O ports) Can be switched for CMOS output/open-drain outputs. Serial I/O: One system (LC723462) PLL: Reference frequencies: 1, 3, 3.125, 5, 6.25, 12.
