CMOS IC
LC72344W, 72345W
Low-Voltage ETR Controller with On-Chip DC-DC
Converter
Overview
The LC72344W and LC72345W are low-voltage
electronic tuning microcontrollers that include a DC-DC
converter, a PLL that operates up to 230 MHz, a 1/4 duty
1/2 bias LCD driver and other functions on chip. The
built-in DC-DC converter provided by these ICs can easily
implement a tuning system voltage generator circuit, and
furthermore, since the transistor required for the low-pass
filter is built in, these ICs can contribute to further end
product cost reductions. Additionally, the DC-DC
converter output voltage can be provided to other external
ICs, making these products optimal for low-voltage
portable audio equipment that includes a radio receiver.
Functions
• Program memory (ROM): 3072 × 16 bits (6 KB)
LC72344W
4096 × 16 bits (8 KB)
LC72345W
• Data memory (RAM): 192 × 4 bits LC72344W
256 × 4 bits LC72345W
• Cycle time: 40 µs (all 1-word instructions)
• Stack: 8 levels
• LCD driver: 48 to 76 segments (1/4 duty, 1/2 bias drive)
• Interrupts: One external interrupt
Timer interrupts (1, 5, 10, and 50 ms)
• A/D converter: Two input channels (5-bit successive
approximation conversion)
• Input ports: 6 ports (of which 2 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 as mask options)
