The LC87F7932B is an 8-bit microcontroller that，centered around a CPU running at a minimum bus cycle time of 250ns，integrates on a single chip a number of hardware features such as 32K-byte flash ROM （onboard programmable），2048-byte RAM，an on-chip debugger，an LCD controller/driver，two sophisticated 16-bit timers/counters （may be divided into 8-bit timers），two 16-bit timers/counters （may be divided into 8-bit timers/counters or 8-bit PWMs），four 8-bit timers with a prescaler，a real time clock function （RTC）， a base timer serving as a time-of-day clock，a synchronous SIO interface with automatic transfer function，an asynchronous/synchronous SIO interface，a UART interface （full duplex），a 7-channel AD converter with a 12-/8-bit resolution selector，a high-speed clock counter，a system clock frequency divider，an internal reset circuit，and a 21-source 10-vector interrupt function.
