LC87F5WC8AVU-QIP-H

8位微控制器带128Kbyte Flash ROM和4096byte RAM

The LC87F5WC8A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 83.3ns, integrate on a single chip a number of hardware features such as 128K-byte flash ROM onboard rewritable, 4096byte RAM, Onchip debugging function, sophisticated 16-bit timers/counters 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 base timer serving as a time-of-day clock, a high-speed clock counter, two synchronous SIO ports with automatic block transmission/reception capabilities, an asynchronous/synchronous SIO port, two UART ports full duplex, four 12-bit PWM channels, an 8-bit 15-channel AD converter, a system clock frequency divider, and a 29-source 10-vector interrupt feature.
