描述 Description

LC87F2708A is an 8-bit microcontroller that, centered around a CPU running at a minimum bus cycle time of 100 ns, integrates on a single chip a number of hardware features such as 8K-byte flash ROM (on-board programmable), 512-byte RAM, an onchip debugger, sophisticated 16-bit timer/counter (may be divided into two 8-bit timers), a 16-bit timer (may be divided into 8-bit timers or two PWMs), a synchronous SIO interface, a high speed 12-bit PWM, two high speed pulse-width/period counters, a 7-channel A-D converter with 12-/8-bit resolution selector, an analog comparator, a watchdog timer, an internal reset circuit, a system clock frequency divider, and a 16-source, 10-vector interrupt feature.
