LC72338规格书详情
Overview
The LC72336 and LC72338 are single-chip microcontrollers for use in electronic tuners. These products include on chip a PLL circuit that can operate at up to 150 MHz and 1/3 duty LCD drivers. They feature a highly efficient instruction set and powerful hardware.

— LC72338: 8191 × 16 bits (16 kB)
• Data memory (RAM): 512 × 4 bits
• All instructions are one-word instructions
• Cycle time: 1.33 µs
• Stack: 8 levels
• LCD drivers: Up to 96 segments (1/3 duty, 1/3 bias)
• Serial I/O: Up to 3 channels (8-bit 3-wire type)
• External interrupts: 2 interrupts (INT0, INT1)
Interrupt on rising or falling edge (selectable)
• Internal interrupts: 3 interrupt
Two built-in timer interrupts and 1 serial I/O interrupt
• Nested interrupt levels: 4 levels
• D/A converter: 4 channels (8-bit PWM output)
• A/D converter: 4 channels (6-bit successive approximation)
• General-purpose ports:
— Input ports: 8
— Output ports: 12 (16 maximum)
— I/O ports: 8 (20 maximum, can be switched between input and output in bit units.)
• PLL block: Supports 4 types of dead zone control, and includes a built-in unlock detection circuit.
Supports 12 different reference frequencies.
• Universal counter: 20 bits (Can be used for either frequency or period measurement.)
• Timers: Eight types of time measurement
• Beep function: Six beep tones
• Reset: Built-in voltage detection type reset circuit
• Halt mode: Stops the controller operating clock.
• Operating supply voltage: 4.5 to 5.5 V (3.5 to 5.5 V if only the controller block operates.)
