The LC87F5VP6A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 66.6 ns, integrate on a single chip a number of hardware features such as 256K-byte flash ROM (onboard rewritable), 10240-byte 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, abase 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.

• Flash ROM : 262144 x 8 bits
• Capable of on-board-programming with wide range, 2.7 to 5.5 V, of voltage source
• Block-erase in 512 byte units
• RAM : 10240 x 9 bits
• Minimum Bus Cycle Time :
• 66.6 ns (15 MHz) V
• = 3.0 to 5.5 V
• 83.3 ns (12 MHz) V
