LC66E2316

CMOS LSI No. 5486 LC66E2316 Four-Bit Single-Chip Microcontroller with 16 KB of On-Chip EPROM Preliminary Overview The LC66E2316 is an on-chip EPROM version of the LC6623XX Series CMOS 4-bit single-chip microcontrollers. The LC66E2316 provides the same functions as the LC662316A, and is pin compatible with that product. Since the LC66E2316 is provided in a window package, it can be reprogrammed repeatedly and is thus optimal for program development. Package Dimensions unit: mm 3127-DIC42S [LC66E2316] 0.25 22 21 14.99 1.27 3.4min 6.5max 37.32 0.8 42 Features and Functions On-chip EPROM 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 4.5 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 10 interrupt factors and 7 interrupt vector locations. — External interrupts: 3 factors/3 vector locations — Internal interrupts: 4 factors/4 vector location...
