Overview
The LC66E5316 is an on-chip EPROM version of the
LC6653XX
Series
CMOS
microcontrollers. The LC66E5316 provides the same
functions as the LC665316A, and is pin compatible with
that product. Since the LC66E5316 is provided in a
window package, it can be reprogrammed repeatedly and is
thus optimal for program development.
4-bit
single-chip
Features and Functions
On-chip EPROM capacity of 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 4.5 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.
