LC87F7J32A: 8-bit LCD Driver Microcontroller with 32K-byte Flash ROM and 1024-byte RAM
The LC87F7J32A 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 32K-byte flash ROM (onboard programmable), 1024-byte RAM, an on-chip debugger, a LCD controller/driver, 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 16-bit timer with a prescaler (may be divided into 8-bit timers), a base timer serving as a timeof- day clock, a day and time counter, a synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex), two 12-bit PWM channels, a 12-bit/8-bit 10-channel AD converter, remote control receive function, a high-speed clock counter, a system clock frequency divider, an internal reset and a 25-source 10-vector interrupt feature.
