Sanyo Electric LC72347W
The LC72346W and LC72347W 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.ABSOLUTE MAXIMUM RATINGS
