LC66P2316

CMOS LSI No. 5487 LC66P2316 Four-Bit Single-Chip Microcontroller with 16 KB of On-Chip OTP PROM Preliminary Overview The LC66P2316 is an on-chip OTP PROM version of the LC6623XX Series CMOS 4-bit single-chip microcontrollers. The LC66P2316 is appropriate for program development and product evaluation since it provides identical functionality and pin compatibility with the LC662316A. Package Dimensions unit: mm 3025B-DIP42S [LC66P2316] 42 22 15.24 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: 36 pins DTMF generator This microcontroller incorporates a circuit that can generate two sine wave outputs, DTMF output, or a melody output for software applications. 8-bit serial interface: one circuit 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 10 interrupt factors and 7 interrupt vector locations. — External interrupts: 3 factors/3 vector locations — Internal interrupts: 4 factors/4 vector locations (Waveform output internal interrupts: 3 factors and 1 vector; shared with external expansion interrupts) Flexible I/O f...
