LC87F2G08A
CMOS IC
8K-byte FROM and 256-byte RAM integrated
8-bit 1-chip Microcontroller
http://onsemi.com
Overview
The LC87F2G08A is an 8-bit microcomputer that, integrates on a single chip a number of hardware features such as
8K-byte flash ROM, 256-byte RAM, an On-chip-debugger, a 16-bit timers/counters, two 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, a 12-bit/8-bit 8-channel AD converter, a system clock
frequency divider, 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 lower level.
(2) System resetting by watchdog timer or low-voltage detection
(3) Having an interrupt source established at either INT0, INT1, INT2, INT4
* 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 five 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
* 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.
Note: Available only when X’tal oscillation is selected.
Onchip Debugger
• Supports software debugging with the IC mounted on the target board.
• Two channels of on-chip debugger pins are available to be compatible with small pin count devices.
DBGP0 (P0), DBGP1 (P1)
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.
Development Tools
• On-chip debugger: (1) TCB87 type B + LC87D2G08A
(2) TCB87 TypeB + LC87F2G08A
(3) TCB87 TypeC (3 wire version) + LC87D2G08A
(4) TCB87 TypeC (3 wire version) + LC87F2G08A
Note: LC87F2G08A has an On-chip debugger but its function is limited.

Note 1: The control of the presence or absence of the programmable pull-up resistors for port 0 and the switching
between low-and high-impedance pull-up connection is exercised in nibble (4-bit) units (P00 to 03 or
P04 to 07).
