CMOS LSI
LC72358N, 72362N, 72366
Single-Chip PLL Microcontrollers
Overview
The LC72358N, LC72362N, and LC72366 are 1.33 碌s
instruction execution time single-chip microcontrollers for
electronic tuning applications. These products incorporate
a high-speed locking circuit and a high-performance direct
PLL circuit that can control the local oscillator C/N
characteristics. These products have 256 or 512 bytes of
RAM and 16K, 24K or 32K bytes of program ROM on
chip, and incorporate a three-channel serial I/O interface,
a six-channel A/D converter and other interfaces.

鈥?Stack: Eight levels
鈥?Serial I/O: Three channels (8-bit 3-wire format)
There are three internal serial clocks: 12.5 kHz,
37.5 kHz and 187.5 kHz.
鈥?External interrupts:
Two channels (the INT0 and INT1 pins)
Switching between rising and falling edge detection is
supported.
鈥?Internal interrupts:
Three channels
鈥?Two internal timer interrupt channels
The timers provide eight interrupt periods: 100 碌s,
1 ms, 2 ms, 5 ms, 10 ms, 50 ms, 125 ms and 250 ms.
鈥?One serial I/O interrupt channel
鈥?Multiple interrupt levels:
Four levels
Hardware priority order
INT0 pin > INT1 pin > SI/O pin > internal timer 0 >
internal timer 1
鈥?A/D converter: Six channels (6-bit successive approx-
imation type)
鈥?General-purpose ports
鈥?Input ports: 10

鈥?Output ports: 28
鈥?I/O ports: 25 (These pins can be switched between
input and output in bit units.)
PLL block
鈥?Built-in sub-charge pump for high-speed locking
鈥?Support for dead zone control
鈥?Built-in unlock detection circuit
鈥?Twelve reference frequencies: 1, 3, 3.125, 5, 6.25, 9,
10, 12.5, 25, 30, 50 and 100 kHz
Universal counter: 20 bits
Supports frequency and period
measurement with counting periods
of 1, 4, 8 and 32 ms.
Timers: Timer interrupt periods
100 碌s, 1 ms, 2 ms, 5 ms, 10 ms, 50 ms, 125 ms
and 250 ms
Beep: Six frequencies: 2.08 kHz, 2.25 kHz, 2.5 kHz,
3.0 kHz, 3.75 kHz, 4.17 kHz.
Reset: Built-in voltage detection type reset circuit
Cycle time: 1.33 碌s (all instructions execute in one
cycle)
Halt mode: The microcontroller operating clock is
stopped in halt mode.
There are four types of event that clear halt
mode: interrupt requests, timer FF
overflows, key inputs, and hold pin inputs.
Operating supply voltage: 4.5 to 5.5 V (3.5 to 5.5 V
when only the controller
block operates)
Package: QFP80E (QIP80E)
OTP version: LC72P366
Development tools: Emulator .................RE32N
Evaluation chip.......LC72EV350
Evaluation chip board
................................EB-72EV350
