CMOS IC
LC87F7DC8A FROM 128K byte, RAM 4K byte on-chip
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F7DC8A 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, a LCD controller/driver, sophisticated 16-bit timer/counter (may
be divided into 8-bit timers), a 16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit
timers with a prescaler, a 16-bit timer with a prescaler (may be divided into 8-bit timers), 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, two UART ports (full duplex), an 12-bit 15-channel AD
converter, two 12-bit PWM channels, a high-speed clock counter, a system clock frequency divider, a small signal
detector, two remote control receive functions, and a 31-source 10-vector interrupt feature.

LC87F7DC8A
Continued from preceding page.
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The CF, RC, X’tal, and frequency variable 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, INT2, INT4, and INT5 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 the remote control receiver circuit.
1) The CF, RC, and frequency variable 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, INT2, INT4, and INT5 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 remote control receiver circuit
