LC72348W Low-Voltage ETR Controller

Ordering number : ENN6472 CMOS IC LC72348G/W, 72349G/W Low-Voltage ETR Controller with On-Chip LCD Driver 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 se.
