LC87F2J32A
CMOS IC
FROM 32K byte, RAM 1024 byte on-chip
8-bit 1-chip Microcontroller
http://onsemi.com
Overview
The LC87F2J32A is an 8-bit microcomputer that, integrates on a single chip a number of hardware features such as
32K-byte flash ROM, 1024-byte RAM, an On-chip-debugger, a 16-bit timer/counter, four 8-bit timers, a base timer
serving as a time-of-day clock, a high-speed clock counter, a synchronous SIO interface, an
asynchronous/synchronous SIO interface, a UART interface, two 12-bit PWM channels, a 12/8-bit 14-channel AD
converter, a system clock frequency divider, remote control receive, an internal reset and an interrupt feature.

Internal Reset Function
• Power-on reset (POR) function
1) POR reset is generated only at power-on time.
2) The POR release level can be selected from 8 levels (1.67V, 1.97V, 2.07V, 2.37V, 2.57V, 2.87V, 3.86V, and
4.35V) through option configuration.
• Low-voltage detection reset (LVD) function
1) LVD and POR functions are combined to generate resets when power is turned on and when power voltage falls
below a certain level.
2) The use/disuse of the LVD function and the low voltage threshold level (7 levels: 1.91V, 2.01V, 2.31V, 2.51V,
2.81V, 3.79V, 4.28V).
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 resetting the HALT mode.
(1) Setting the reset pin to the low level
(2) System resetting by watchdog timer or low-voltage detection
(3) Occurrence of an interrupt
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The CF, RC, and crystal oscillators automatically stop operation.
2) There are four ways of resetting the HOLD mode.
(1) Setting the reset pin to the low level.
(2) System resetting by watchdog timer or low-voltage detection
(3) Having an interrupt source established at either INT0, INT1, INT2, INT4, or INT5
* INT0 and INT1 HOLD mode reset is available only when level detection is set.
(4) Having an interrupt source established at port 0
• X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer.
1) The CF and RC oscillators automatically stop operation.
2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.
3) There are six ways of resetting the X'tal HOLD mode.
(1) Setting the reset pin to the low level
(2) System resetting by watchdog timer or low-voltage detection
(3) Having an interrupt source established at either INT0, INT1, INT2, INT4, or INT5
* INT0 and INT1 HOLD mode reset is available only when level detection is set.
(4) Having an interrupt source established at port 0
(5) Having an interrupt source established in the base timer circuit
(6) Having an interrupt source established in the infrared remote controller receiver circuit
On-chip Debugger
• Supports software debugging with the IC mounted on the target board (LC87D2J32A).
LC87F2J32A has an On-chip debugger but its function is limited.
Data Security Function (flash versions only)
• Protects the program data stored in flash memory from unauthorized read or copy.
Note: This data security function does not necessarily provide absolute data security.
