LC87F1JJ2A
CMOS IC
FROM 192K byte, RAM 16384 byte on-chip
8-bit 1-chip Microcontroller
with USB-host controller
http://onsemi.com
Overview
The LC87F1JJ2A is an 8-bit microcomputer that, integrates on a single chip a number of hardware features such as
192K-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 realtime 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.

Standby Function
• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.
1) Oscillation is not halted automatically.
2) There are three ways of releasing the HALT mode.
(1) Setting the reset pin to the lower level.
(2) System resetting by watchdog timer
(3) Generating an interrupt
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The PLL base clock generator, CF, RC and crystal oscillators automatically stop operation.
2) There are five ways of releasing the HOLD mode.
(1) Setting the reset pin to the lower level
(2) System resetting by watchdog timer
(3) Having an interrupt source established at one of the INT0, INT1, INT2, INT4, and INT5 pins
* The INT0 and INT1 pins must be configured only for level detection.
(4) Having an interrupt source established at port 0
(5) Having an bus active interrupt source established in the USB host control circuit
• X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer.
1) The PLL base clock generator, CF and RC oscillator automatically stop operation.
2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.
3) There are seven ways of releasing the X'tal HOLD mode.
(1) Setting the reset pin to the low level
(2) System resetting by watchdog timer
(3) Having an interrupt source established at one of the INT0, INT1, INT2, INT4, and INT5 pins
* The INT0 and INT1 pins must be configured only for level detection.
(4) Having an interrupt source established at port 0
(5) Having an interrupt source established in the base timer circuit
(6) Having an bus active interrupt source established in the USB host control circuit
(7) Having an interrupt source established in the infrared remote controller receiver circuit

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 optional settings. The procedure for marking the optional settings 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.
Circuit example 1: When VDD1=VDD2=3.3V
• Inactivating the reference voltage circuit (selection (4)).
• Connecting VDD3 to VDD1 and VDD2.
