The LC87F2C64A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 83.3ns, integrates on a single chip a number of hardware features such as 64K-byte flash ROM (onboard programmable), 2048-byte RAM, an on-chip debugger, sophisticated 16-bit timer/counter (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 calendar function (RTC), High-speed clock counter, a synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, two channels of UART interface (full duplex), four 12bit-PWMs, a 12/8-bit 16-channel AD converter, a system clock frequency divider, an internal reset function and a 28-source 10-vector interrupt feature.
