LC87F14C8A
CMOS IC
FROM 128K byte, RAM 10K byte on-chip
8-bit 1-chip Microcontroller
with USB-host controller
Overview
The SANYO LC87F14C8A 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), 10240-byte RAM, an on-chip debugger, a sophisticated 16-bit timers/counters (may be divided into 8-bit
timers), 16-bit timers/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with
a prescaler, a base timer serving as a time-of-day clock, three synchronous SIO interface (with automatic block transmit/
receive function), an asynchronous/synchronous SIO interface, a UART interface (full duplex), a Full-Speed USB
interface (host controller), an 8-bit 12-channel AD converter, two 12-bit PWM channels, a system clock frequency
divider, ROM correction function, and a 36-source 10-vector address 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 selection. 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.
