LC87F1HC8A
CMOS IC
128K-byte FROM and 16384-byte RAM integrated
8-bit 1-chip Microcontroller
with USB-host controller
http://onsemi.com
Overview
The LC87F1HC8A is an 8-bit microcomputer that, integrates on a single chip a number of hardware features such as
128K-byte flash ROM, 16384-byte RAM, an on-chip debugger, a 16-bit timer/counter, a 16-bit timer, four 8-bit
timers, 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, a full-speed USB interface (host
control function), a 12-channel AD converter, 2 channels of 12-bit PWM, a system clock frequency divider, an
infrared remote control receiver circuit, and an interrupt feature.

USB Reference Power Option
When a voltage 4.5 to 5.5V is supplied to VDD1 and the internal USB reference voltage circuit is activated, the
reference voltage for USB port output is generated. The active/inactive state of the reference voltage circuit can be
switched by option select. The procedure for marking the option selection is described below.

• When the USB reference voltage circuit is made inactive, the level of the reference voltage for USB port output is
equal to VDD1.
• Selection (2) or (3) can be used to set the reference voltage circuit inactive in HOLD or HALT mode.
• When the reference voltage circuit is activated, the current drain increases by approximately 100μA compared with
when the reference voltage circuit is inactive.
Example 1: VDD1=VDD2=3.3V
• Inactivating the reference voltage circuit (selection (4)).
• Connecting VDD3 to VDD1 and VDD2.
