Product Details

Description



Features:

• On-chip ROM capacitiy of 4, 6, 8, 12, and 16 kilobytes, and an on-chip RAM capacity of 512 * 4 bits.
• Fully supports the LC66000 Series common instruction set (128 instructions).
• I/O ports: 42 pins
• A sub-oscillator circuit can be used (option)
   This circuit allows power dissipation to be reduced by operating at lower speeds.
• 8-bit serial interface: two circuits (can be connected in cascade to form a 16-bit interface)
• Instruction cycle time: 0.95 to 10 s (at 3 to 5.5 V)
• Powerful timer functions and prescalers
   - Time limit timer, event counter, pulse width measurement, and square wave output using a 12-bit timer.
   - Time limit timer, event counter, PWM output, and square wave output using an 8-bit timer.
   - Time base function using a 12-bit prescaler.
• Powerful interrupt system with 8 interrupt factors and 8 interrupt vector locations.
   - External interrupts: 3 factors/3 vector locations
   - Internal interrupts: 5 factors/5 vector locations
• Flexible I/O functions
   16-value comparator inputs, 20-mA drive outputs,inverter circuits, pull-up and open-drain circuits selectable as options.
• Optional runaway detection function (watchdog timer)
• 8-bit I/O functions
• Power saving functions using halt and hold modes.
• Packages: DIP48S, QIP48E (QFP48E)
• Evaluation LSIs: LC66599 (evaluation chip) + EVA800/850-TB662YXX2

Note: 1. Applies to pins with open-drain output specifications. For pins with other than open-drain output specifications, the ratings in the pin column for that pin apply.
2. For the oscillator input and output pins, levels up to the free-running oscillation level are allowed.
3. Sink current (Applies to P8 and PD when either the CMOS output specifications or the inverter array specifications have been selected.)
4. Source current (Applies to all pins except P8 and PD for which the pull-up output specifications, the CMOS output specifications, or the inverter array specifications have been selected. Applies to PD pins for which the inverter array specifications have been selected.) Contact your Sanyo representative for the electrical characteristics when the inverter array or buffer array options are specified.
5. We recommend the use of reflow-soldering techniques to solder-mount QFP packages.
    Please consult with your Sanyo representative for details on process conditions if the package itself is to be directly immersed in a dip-soldering bath (dip-soldering spray techniques).


Description

The LC665304A, LC665306A, LC665308A, LC665312A, and LC665316A are 4-bit CMOS microcontrollers that integrate on a single chip all the functions required in a system controller, including ROM, RAM, I/O ports, a serial interface, 16-value comparator inputs, timers, interrupt functions, and an optional sub-oscillator circuit. These microcontrollers are available in a 48-pin package.
