LC87F6AC8A: Microcontroller, 8-bit, integrated VFD Controller, 128K-byte Flash ROM, 4096-byte RAM
The LC87F6AC8A is an 8-bit microcontroller 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 128K-byte flash ROM (onboard programmable), 4096-byte RAM, on-chip debugging function, a vacuum fluorescent display (VFD) automatic display controller/driver, a 16-bit timer/counter (may be divided into 8-bit timers), a 16-bit timer/counter (may be divided into 8-bit timer/counter 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 used as a time-of-day clock, a high-speed clock counter, a system clock frequency divider, two synchronous SIO with automatic transfer capability, an asynchronous/synchronous SIO, two channels of 12-bit PWM modules, an 8-bit 15-channel AD converter, a small signal detector, and a 27-source 10-vector interrupt feature.
