LC87F1HC4B
CMOS LSI
8-bit Microcontroller
with USB-host Controller
128K-byte FROM / 12288-byte RAM / 48-pin
www.onsemi.com
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.

Note 1: With the FSG onboard programmer (AF9101/AF9103) and the serial interface driver (SIB87) provided by
ON Semiconductor, PC-less standalone onboard programming is possible
Note 2: Depending on programming conditions, it is necessary to use a dedicated programming device and a program.
Please contact our company or FSG if you have any questions or difficulties regarding this matter.

Port Output Types
The table below lists the types of port outputs and the presence/absence of a pull-up resistor.
Data can be read into any input port even if it is in the output mode.

Note 1: Programmable pull-up resistors for port 0 are controlled in 4 bit units (P00 to 03, P04 to 07).
Power Pin Treatment
Connect the IC as shown below to minimize the noise input to the VDD1 pin. and extend the backup period. Be sure to
electrically short the VSS1, VSS2, and VSS3 pins.
Example 1: When the microcontroller is in the backup state in the HOLD mode, the power to sustain the high level of
output ports is supplied by their backup capacitors.
