LC66P5316

CMOS LSI No. 5489 LC66P5316 Four-Bit Single-Chip Microcontroller with 16 KB of On-Chip OTP PROM Preriminary Overview The LC66P5316 is an on-chip OTP PROM version of the LC6653XX Series CMOS 4-bit single-chip microcontrollers. The LC66P5316 is appropriate for program development and product evaluation since it provides identical functionality and pin compatibility with the LC665316A. Package Dimensions unit: mm 3149-DIP48S [LC66P5316] 0.25 48 25 15.24 13.8 46.0 0.51min 0.48 1.05 1.78 2.53 Features and Functions On-chip OTP ROM capacity of 16 kilobytes, and an onchip 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 4.0 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-valu...
