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 series except the IF counter function.
These ICs are optimal for use in low-voltage portable
audio equipment that includes a radio receiver.

(5-bit successive approximation
conversion)
• Input ports: 7 ports (of which three can be switched for
use as A/D converter inputs)
• Output ports: 6 ports (of which 1 can be switched for use
as the beep tone output and 2 are open-
drain ports)
• I/O ports: 16 ports (of which 8 can be switched for use
as LCD ports and as mask options)
