LC87F1A32A: 8-bit Microcontroller with Full-Speed USB integrated 32K-byte Flash ROM and 2048-byte RAM
LC87F1A32A is an 8-bit 1-chip microcontroller that, centered around a CPU running at a minimum bus cycle time of 83.3 ns, integrates on a single chip a number of hardware features such as 32K-byte flash ROM (on-board programmable), 2048-byte RAM, an onchip debugger, sophisticated 16-bit timers/counters (may be divided into two 8-bit timers), a 16-bit timer (may be divided into 8-bit timers or two PWMs), two 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, a high speed clock counter, two channels of synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex), a full speed USB interface (function), a 12-bit, 12-channel A-D converter (12- or 8-bit resolution selectable), two channels of 12-bit PWM, a system clock frequency divider, an infrared remote controller receiver circuit, and a 28-source, 10-vector interrupt feature.
