The LC87F1D64A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 62.5ns, integrates on a single chip a number of hardware features such as 64K-byte flash ROM (onboard programmable), 4096-byte RAM, an on-chip debugger, a sophisticated 16-bit timers/counters (may be divided into 8-bit timers), 16-bit timers/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), two 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, a high-speed clock counter, two synchronous SIO interface (with automatic block transmit/ receive function), an asynchronous/synchronous SIO interface, a UART interface (full duplex), a Full-Speed USB interface (function controller), 12-channel 12-bit A/D converter with 12-/8-bit resolution selector, two 12-bit PWM channels, a system clock frequency divider, an infrared remote control receiver circuit, and a 30-source 10-vector address interrupt feature.

• Flash ROM : 65536 x 8 bits
• Capable of on-board-programming with wide range, 3.0 to 5.5V, of voltage source.
• Block-erasable in 128 byte units
• Writes data in 2-byte units
• RAM : 4096 x 9 bits
• Minimum Bus Cycle : 62.5ns (CF=16MHz)
• Note: The bus cycle time here refers to the ROM read speed.
• Minimum Instruction Cycle Time : 188ns (CF=16MHz)
