LC87F1JJ8A
CMOS IC
FROM 192K byte, RAM 24576 byte on-chip
8-bit 1-chip Microcontroller
with USB-host controller
Overview
The LC87F1JJ8A 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 192K-byte flash ROM (onboard programmable),
24576-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 realtime
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
41-source 10-vector interrupt feature.

LC87F1JJ8A
„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

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.
