The LC87F5G32A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 100ns, integrates on a single chip a number of hardware features such as 32K-byte flash ROM (onboard programmable), 1024-byte RAM, an on-chip debugger, sophisticated 16-bit timers/counters (may be divided into 8-bit timers), a 16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, a high-speed clock counter, a synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex), a 12-bit/8-bit 12-channel AD converter, two 12-bit PWM channels, a system clock frequency divider, and a 22-source 10-vector interrupt feature.

• Flash ROM : 32768 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
• RAM : 1024 x 9 bits
• Minimum Bus Cycle : 100ns (10MHz)
• Note : The bus cycle time here refers to the ROM read speed.
• Minimum Instruction Cycle Time : 300ns (10MHz)
