LC877917A
CMOS IC
16K-byte ROM and 512-byte RAM integrated
8-bit 1-chip Microcontroller
Overview
The SANYO LC877917A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time
of 250ns, integrates on a single chip a number of hardware features such as 16K-byte ROM, 512-byte RAM, 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 calendar function (RTC), a
synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO
interface, a UART interface (full duplex), a 12-bit/8-bit 7-channel AD converter, high-speed clock counter, a system
clock frequency divider, a power on reset function and a 21-source 10-vector interrupt feature.

LC877917A
Standby Function
• HALT mode
HALT mode is used to reduce power consumption. During the HALT mode, program execution is stopped but
peripheral circuits keep operating (Some parts of serial transfer operation stop.)
(1) Oscillation circuits are not stopped automatically.
(2) Released by the system reset or interrupts.
• HOLD mode
HOLD mode is used to reduce power consumption. Program execution and peripheral circuits are stopped.
(1) CF, RC and crystal oscillation circuits stop automatically.
(2) Released by any of the following conditions.
1) Low level input to the reset pin
2) Watchdog timer interrupt
3) Specified level input to one of INT0, INT1, INT2
4) Port 0 interrupt
5) SPI interrupt by receiving 1-byte (8-bit clock)
• X’tal HOLD mode
X’tal HOLD mode is used to reduce power consumption. Program execution is stopped.
All peripheral circuits except the base timer are stopped.
(1) CF and RC oscillation circuits stop automatically.
(2) Crystal oscillator operation is kept in its state at HOLD mode inception.
(3) Released by any of the following conditions.
1) Low level input to the reset pin
2) Watchdog timer interrupt
3) Specified level input to one of INT0, INT1, INT2
4) Port 0 interrupt
5) Base-timer interrupt
6) RTC interrupt
7) SPI interrupt by receiving 1-byte (8-bit clock)
