LC87F1HC4B Overview The LC87F1HC4B 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), 12288-byte RAM, an on-chip debugger, a sophisticated 16-bit timer/counter (may be divided into 8-bit timers), a 16-bit timer (may be divided into 8-bit timers or PWMs), four 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, 3 channels of synchronous SIO interface with automatic data transfer capabilities, an asynchronous/synchronous SIO interface, a UART interface (full duplex), a full-speed USB interface (host control function), an 8-bit 12-channel AD converter, 2 channels of 12-bit PWM, a system clock frequency divider, an infrared remote control receiver circuit, and a 40-source 10-vector interrupt feature. Features Flash ROM 131072 8 bits Capable of on-board programming with a wide range of supply voltages : 3.0 to 5.5V Block-erasable in 128 byte units Writes data in 2-byte units RAM 12288 9 bits Package Form SQFP48 : Pb-Free type Bus Cycle Time 83.3ns (When CF=12MHz) Note : The bus cycle time here refers to the ROM read speed. CMOS LSI 8-bit Microcontroller with USB-host Controller 128K-byte FROM / 12288-byte RAM / 48-pin * This product is licensed from Silicon Storage Technology, Inc. (USA).
