Sanyo LC72316W Specifications

Ordering number : ENN*6650

N3001TN (OT) No. 6650-1/12

Overview

The LC72314W, LC72315W and LC72316W are
ultralow-voltage (0.9 to 1.8 V) 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.

Function

• Program memory (ROM):

— 4096 × 16 bits (8K bytes) : LC72314W
— 6144 × 16 bits (12K bytes): LC72315W
— 8192 × 16 bits (16K bytes): LC72316W

• Data memory (RAM):

— 256 × 4 bits: LC72314W
— 512 × 4 bits: LC72315W/72316W

• Cycle time: 40 µs (all 1-word instructions)

• Stack: 8 levels

• LCD driver:
48 to 112 segments (1/4 duty, 1/2 bias drive)

• Interrupts: Two external interrupts

Timer interrupts (1, 5, 10, and 50 ms)

• A/D converter: Four input channels
(6-bit successive approximation conversion)

• Input ports: 11 ports (of which three can be switched for
use as A/D converter inputs)

• Output ports: 8 ports (of which 1 can be switched for use
as the beep tone output and 4 are open-drain ports)

• I/O ports: 29 ports (of which 16 can be switched for use
as LCD ports and as mask options, of which 3 can be
switched for use as serial I/O ports)

• Serial I/O: One system (LC72315W/72316W)

• PLL: Reference frequencies:
1, 3, 3.125, 5, 6.25, 12.5, and 25 kHz

• Input frequencies:
FM band: 10 to 250 MHz
AM band (high): 2 to 20 MHz
AM band (low): 0.5 to 10 MHz

• Input sensitivity:FM band:
35 mVrms (130 MHz to 250 MHz: 50 mVrms)
AM band (high, low): 35 mVrms

• IF counter: HCTR input pin 0.4 to 15 MHz (35 mVrms)

• External reset input: During CPU and PLL operations,
instruction execution is started from location 0.

Continued from preceding page.

• Built-in power-on reset circuit:
The CPU starts execution from location 0 when power is
first applied.

• Halt mode: The controller-operating clock is stopped.

• Backup mode: The crystal oscillator is stopped.

• Static power-on function:
Backup state is cleared with the PF port

• Beep tone: 1.5 and 3.1 kHz

• Built-in DC-DC converter:
For LCD and A/D converter use (3 V)
Can also be used for TU + B creation by using a
secondary coil.

• Built-in remaining battery life verification function:
Converts the VDDpin level to digital.

• Memory retention voltage: 0.8 V or higher

• Dedicated memory power supply: The RAM retention
time has been increased by the provision of a dedicated
memory power supply.

• Package: SQFP-80 (0.5-mm pitch)

• VDDpower supply: 0.9 to 1.8 V

• Operating frequency: 75 kHz
