The LC87F2R04A is an 8-bit microcontroller that, centered around a CPU running at a minimum bus cycle time of 83.3 ns, integrates a number of hardware features such as 4K-byte flash ROM, 128-byte RAM, an on-chip debugger, sophisticated 16-bit timers/counters (may be divided into 8-bit timers), two 8-bit timers with a prescaler, an asynchronous/synchronous SIO interface, a 12-bit/8-bit 8-channel AD converter, an internal reset and a 12-source 8-vector interrupt feature.

• Flash ROM : 4096 × 8 bits
• Capable of on-board programming with wide range (2.2 to 5.5V) of voltage source.
• Block-erasable in 128 byte units
• Writable in 2-byte units
• RAM : 128 × 9 bits
• Minimum Bus Cycle :
• 83.3ns (12MHz at VDD=2.7V to 5.5V)
• 100ns (10MHz at VDD=2.2V to 5.5V)
• Note: The bus cycle time here refers to the ROM read speed.
