Four-Bit Single-Chip Microcontrollers
with 4, 6, 8, 12, and 16 KB of On-Chip ROM
Overview
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.
Features and Functions
• 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 µs (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) +

P33/HOLD
Hold mode control input
• Hold mode is set up by the HOLD
instruction when HOLD is low.
• In hold mode, the CPU is restarted by
setting HOLD to the high level.
I
• This pin can be used as input port P33
along with P30 to P32.
• When the P33/HOLD pin is at the low
level, the CPU will not be reset by a
low level on the RES pin. Therefore,
applications must not set P33/HOLD
low when power is first applied.
