LC72349W
Overview
The LC72348G/W and LC72349G/W are low-voltage electronic tuning microcontrollers that include a PLL that operates up to 230 MHz and a 1/4 duty 1/2 bias LCD driver on chip. These ICs can contribute to further end product cost reduction than the LC72341 series while providing improved standby current characteristics. Also these ICs can use the application program for the LC72341 series except the IF counter function. These ICs are optimal for use in low-voltage portable audio equipment that includes a radio receiver.
