The LC87F0A08A is an 8-bit microcontroller that, centered around a CPU running at a minimum bus cycle time of 12ns, integrates on a single chip a number of hardware features such as 8K-byte flash ROM, 256-byte RAM, an on-chip debugger, a sophisticated 16-bit timer/counter, a 16-bit timer/counter, a 16-bit timer with a prescaler, a base timer serving as a realtime clock, an asynchronous/synchronous SIO interface, a 12-bit 8-channel AD converter with 12-/8-bit resolution selector, a 20X amplifier, constant-voltage detect interrupt, a comparator, a system clock frequency divider, an internal reset circuit, and a 16-source 9-vector interrupt feature.

• Flash ROM :
• 8192 x 8 bits
• Capable of on-board programming with a wide range of supply voltage 2.7 to 5.5V
• Block-erasable in 128-byte units
• Writes data in 2-byte units
• RAM : 256 x 9 bits
• Minimum Bus Cycle Time :
• 125ns (8MHz at VDD=2.5V to 5.5V)
• 250ns (4MHz at VDD=2.5V to 5.5V)
• Note: The bus cycle time here refers to the ROM read speed.
