LC87F76C8A
CMOS IC
FROM 128K byte, RAM 4K byte on-chip
8-bit 1-chip Microcontroller
http://onsemi.com
Overview
The LC87F76C8A 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 128K-byte flash ROM (onboard
programmable), 4K-byte RAM, an on-chip debugger, an LCD controller/driver, 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 8-bit PWMs), four 8-bit timers
with a prescaler, a base timer serving as a time-of-day clock, a day and time counter, a synchronous SIO interface
(with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART
interface (full duplex), a 8-bit 12-channel AD converter, two 12-bit PWM channels, a high-speed clock counter, a
system clock frequency divider, a small signal detector, an infrared remote controller receiver function, and a 22-
source 10-vector interrupt feature.
Features
Flash ROM
• Capable of on-board-programming with a wide range of souce voltages: 3.0 to 5.5V.
• Block-erasable in 2-byte units
• 131072 × 8 bits (LC87F76C8A)
RAM
• 4096 × 9 bits (LC87F76C8A)
Minimum Bus Cycle Time
• 83.3ns (12MHz)
• 125ns (8MHz)
• 250ns (4MHz)
VDD=3.0 to 5.5V
VDD=2.5 to 5.5V
VDD=2.2 to 5.5V
Note: The bus cycle time here refers to the ROM read speed.

LC87F76C8A
Standby Function
• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.
(Some parts of the serial transfer function stops operation.)
1) Oscillation is not stopped automatically.
2) Canceled by a system reset or occurrence of an interrupt
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The CF, RC, X’tal, and multifrequency RC oscillators automatically stop operation.
2) There are three ways of resetting the HOLD mode.
(1) Setting the reset pin to the low level
(2) Setting at least one of the INT0, INT1, and INT2, pins to the specified level
(3) 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
and infrared remote controller circuit.
1) The CF, RC, and multifrequency 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) Setting at least one of the INT0, INT1, and INT2 pins to the specified level
(3) Having an interrupt source established at port 0
(4) Having an interrupt source established in the base timer circuit
(5) Having an interrupt source established in the infrared remote control receiver circuit

Same Package and Pin Assignment as Mask ROM Version.
1) LC877600 series options can be specified by using flash ROM data. Thus the board used for mass production can
be used for debugging and evaluation without modifications.
2) If the program for the mask ROM version is used, the size of the available ROM/RAM spaces is the same as
that of the mask ROM version.
