LC66P5316 - Sanyo Semicon Device

LC66P5316 Four-Bit Single-Chip Microcontrollers with 4/ 6/ 8/ 12/ and 16 KB of On-Chip ROM

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 compat.

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 w.
