CMOS IC
LC72348G/W, 72349G/W
Low-Voltage ETR Controller
with On-Chip LCD Driver
Overview
Package Dimensions
The LC72348G/W and LC72349G/W are low-voltage unit: mm
electronic tuning microcontrollers that include a PLL that 3231-QIP64G
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.
