The LC87F5JC8A is an 8-bit microcomputer 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, an on-chip debugger, 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 16-bit timer with a prescaler (may be divided into 8-bit timers), a base timer serving as a time-of-day clock, a high-speed clock counter, a synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex), an 8-bit 11-channel AD converter, two 12-bit PWM channels, a system clock frequency divider, ROM correction function, and a 26-source 10-vector interrupt feature.

• Flash ROM :
• Capable of on-board-programing with wide range, 3.0 to 5.5V, of voltage source.

• 131072 x 8-bits (LC87F5JC8A)
• RAM : 4096 x 9-bits
• Minimum Bus Cycle :
• 83.3ns (12MHz) VDD=3.0 to 5.5V
• 125ns (8MHz) VDD=2.5 to 5.5V
• 500ns (2MHz) VDD=2.2 to 5.5V
