LC87F2K08A
Advance Information
CMOS LSI
8-bit Microcontroller
8K-Byte Flash ROM / 256-Byte RAM / 24-pin
http://onsemi.com
Overview
The LC87F2K08A 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 8K-byte flash ROM (onboard
programmable), 256-byte RAM, an on-chip debugger function, two sophisticated 16-bit timers/counters (may be
divided into 8-bit timers), an asynchronous/synchronous SIO interface, a 5-channel AD converter with 12/8-bit
resolution selector, eight analog comparators, two AMP circuits, an IGBT control circuit (PPG), a watchdog timer, an
internal reset circuit, a system clock frequency divider, and a 18-source 10-vector interrupt feature.
It is optimal for controlling the IH cooking heaters and other appliances.

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 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 releasing the HOLD mode.
(1) Setting the reset pin to the lower level.
(2) System resetting by watchdog timer or low-voltage detection
(3) Having an interrupt source established at either INT0, INT1, INT2, or INT4
* INT0 and INT1 HOLD mode release is available only when level detection is set.
On-chip debugger
● Supports software debugging with the IC mounted on the target board.
Data security function
● 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.
Development tools
● On-chip debugger: TCB87 Type C + LC87F2K08A

On-chip Debugger pin connection requirements
The on-chip debugger pin (OWPO) must be pulled down (with 100 KΩ) on the user's board.
It is also recommended that a connector be installed to cable with the debugger tool (TCB87 Type C).
The connector must have three connections, i.e., GND, OWPO, and VDD.
Note : Be sure to electrically short-circuit between the VSS1 and VSS2 pins.
