SANYO LC72344W

Ordering number : ENN6171
CMOS IC
LC72344W, 72345W
Low-Voltage ETR Controller with On-Chip DC-DC
Converter
Overview
Package Dimensions
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.

Special-purpose ports for key return signal input designed with a low threshold voltage. When
a key matrix is formed in combination with port PB, simultaneous multiple key presses with
up to 3 keys can be detected. The pull-down resistors are set up for all four pins at the same
time with the IOS instruction (PWn = 2.b1). This setting cannot be specified for individual
pins. In backup mode, these pins go to the input disabled state, and the pull-down resistors
are disabled after a reset.

Unbalanced CMOS outputs. These outputs are switched with the IOS 0 instruction. Since
these outputs are unbalanced, no diodes are required to prevent short circuits due to
simultaneous multiple key presses. These outputs go to the high-impedance output state in
backup mode. After a reset, they go to the high-impedance output state and remain in that
state until an output instruction (OUT, SPB, or RPB) is executed.

(*)
General-purpose output and beep tone output shared function ports (PE0 only). The BEEP
instruction is used to switch PE0 between the general-purpose output port and beep tone
output functions. To use PE0 as a general-purpose output port, execute a BEEP instruction N-channel open-drain output
with b2 set to 0. Set b2 to 1 to use PE0 as the beep tone output port. The b0 and b1 bits are
used to select the beep tone frequency. There are two beep tone frequencies supported.

BEEP/PE0
19
PE1
*: When PE0 is set up as the beep tone output, executing an output instruction to PN0 only
changes the state of the internal output latch, it does not affect the beep tone output in any
way. Only the PE0 pin can be switched between the general-purpose output function and the
beep tone output function; the PE1 pin only functions as a general-purpose output. These
pins go to the high-impedance state in backup mode and remain in that state until an output
instruction or a BEEP instruction is executed. Since these ports are open-drain ports,
resistors must be inserted between these pins and VDD. These ports are set to their generalpurpose output port function after a reset.

I
The IOS instruction (Pwn = FH) is used to switch between the general-purpose input and A/D
converter port functions. The general-purpose input and A/D converter port functions can be
switched in a bit units, with 0 specifying general-purpose input, and 1 specifying the A/D
converter input function. To select the A/D converter function, set up the A/D converter pin
with an IOS instruction with Pwn set to 1. The A/D converter is started with the UCC
instruction (b3 = 1, b2 = 1). The ADCE flag is set when the conversion completes. The INR
instruction is used to read in the data.
CMOS input/analog input
*: If an input instruction is executed for one of these pins which is set up for analog input, the
read in data will be at the low level since CMOS input is disabled. In backup mode these pins
go to the input disabled high-impedance state. These ports are set to their general-purpose
input port function after a reset. The A/D converter is a 5-bit successive approximation type
converter, and features a conversion time of 1.28 ms. Note that the full-scale A/D converter
voltage (1FH) is (63/96) times VDC3.

In backup mode, these pins go to the input disabled high-impedance state if set up as
general-purpose outputs, and are fixed at the low level if set up as segment outputs. These
ports are set up as segment outputs after a reset.
Although the general-purpose port/LCD port setting is a mask option, the IOS instruction
must be used as described above to set up the port function.

System reset input.
In CPU operating mode or halt mode, applications must apply a low level for at least one full
machine cycle to reset the system and restart execution with the PC set to location 0. This
pin is connected in parallel with the internal power on reset circuit.
Battery presence/absence discrimination.
The internal clock oscillator starts when a high level is input to this pin.
The IN instruction can be used to determine whether or not a battery is present.

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer’s
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer’s products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
In the event that any or all SANYO products (including technical data, services) described or contained
herein are controlled under any of applicable local export control laws and regulations, such products must
not be exported without obtaining the export license from the authorities concerned in accordance with the
