Description
The LC87F2H08A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 83.3 ns, integrates a number of hardware features such as 8K-byte flash ROM (on-board programmable), 256-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), two 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, a high speed clock counter, a synchronous SIO interface, an asynchronous/synchronous SIO interface, a UART interface (full duplex), an 12/8-bit 9-channel AD converter, two 12-bit PWM channels, a system clock frequency divider, an internal reset, and a 20-source 10-vector interrupt feature.
- Flash ROM : 8192 × 8 bits
Capable of on-board programming with a wide range (2.2 to 5.5V) of voltage source.
Block-erasable in 128 byte units
Writable in 2-byte units - RAM : 256 × 9 bits
- Minimum Bus Cycle :83.3ns (12MHz at VDD=2.7V to 5.5V)100ns (10MHz at VDD=2.2V to 5.5V)250ns (4MHz at VDD=1.8V to 5.5V)Note: The bus cycle time here refers to the ROM read speed.
