Overview
The LC87F2C64A 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 64K-byte flash ROM (onboard
programmable), 2048-byte RAM, an on-chip debugger, sophisticated 16-bit timer/counter (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 calendar function (RTC), High-speed clock counter, a synchronous SIO interface (with automatic block
transmission/reception capabilities), an asynchronous/synchronous SIO interface, two channels of UART interface
(full duplex), four 12bit-PWMs, a 12/8-bit 16-channel AD converter, a system clock frequency divider, an internal
reset function and a 28-source 10-vector interrupt feature.
Features
Flash ROM
• On-board-programmable with wide range (3.0 to 5.5V) of voltage source
• Block-erasable in 128 byte units
• Writable in 2-byte units
• 65536 × 8 bits
RAM
• 2048 × 9 bits
Minimum Bus Cycle
• 83.3ns (12MHz at VDD=3.0V to 5.5V)
• 250ns (4MHz at VDD=2.4V to 5.5V)
Note: The bus cycle time here refers to the ROM read speed.
