Any and all SANYO Semiconductor products described or contained herein do not have specifications
that can handle applications that require extremely high levels of reliability, such as life-support systems,
aircraft's control systems, or other applications whose failure can be reasonably expected to result in
serious physical and/or material damage. Consult with your SANYO Semiconductor representative
nearest you before using any SANYO Semiconductor products described or contained herein in such
applications.
SANYO Semiconductor assumes no responsibility for equipment failures that result from using products
at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor
products described or contained herein.
LC723341E
Overview
The LC723341E is a single-chip microcontroller/electronic tuner that also integrates a 250 MHz PLL circuit and a
1/4-duty 1/2-bias LCD driver on the same chip.
Functions
Program memory (ROM): 4096
× 16 bits (8 KB)
Data memory (RAM): 256
× 4 bits
Cycle time: 1.33 s (all one-word instructions) at 4.5 MHz
Stack: 8 levels
LCD driver: 48 to 80 segments (1/4-duty 1/2-bias drive)
Interrupts: External interrupts: 2 systems
Timer interrupts: 2 systems (1, 5, 10 or 50 ms)
A/D converter: Four input channels (6-bit successive approximation conversion)
Dedicated input ports: 8 ports (of which 4 can be switched for use as A/D converter inputs)
Dedicated output ports: 10 ports (of which 6 are open-drain ports and 4 can be switched between CMOS and
open-drain specifications)
I/O ports: 19 ports (of which 8 can be switched for use as segment ports)
PLL: Reference frequencies: 3, 3.125, 5, 6.25, 12.5 and 25 kHz
Supports dead zone control (4 types) and features a built-in unlock detection circuit.
Input frequency (input sensitivity): FM band - 10 to 250 MHz
AM band- 0.5 to 40 MHz
Input sensitivity: FM band - 35 mV rms (Above 130 MHz: 50 mV rms)
AM band - 35 mV rms
IF counting: HCTR input - 0.4 to 12 MHz (35 mV rms)
External reset input: The program counter starts from location 0 during CPU and PLL operation
Reset: Built-in voltage detection reset circuit
Halt mode: The controller's operating clock is temporarily slowed to reduce current drain.
Backup mode: The crystal oscillator is stopped.
Static power on function: Backup mode is cleared using the PF port.
Beep tone: Frequencies of 0.75, 1.25, 1.5, 2.08. 2.5, 3.125, and 6.25 kHz
Memory retention voltage: 0.9 V or higher
VDD: PLL 4.5 to 5.5 V
CPU 3.5 to 5.5 V
Package: QIP64E (0.8 mm pitch)
Ordering number : ENN8013
CMOS IC
ETR Controller
