LC87F2H08A
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F2H08A 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 (On-board-
programmable), 256-byte RAM, an On-chip-debugger, sophisticated 16-bit timers/counters (may be divided into 8-bit
timers), a 16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), two 8-bit timers with
a prescaler, 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 (full duplex), two 12-bit PWM channels, a 12/8-bit
9-channel AD converter, a system clock frequency divider, an internal reset and a 20-source 10-vector interrupt feature.

(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

(2) System resetting by watchdog timer or low-voltage detection.
(3) Having an interrupt source established at either INT0, INT1, INT2, INT4 or INT5

Note: Available only when X’tal oscillation is selected.

Note 6-1: The quantization error (±1/2LSB) must be excluded from the absolute accuracy. The absolute accuracy must
be measured in the microcontroller's state in which no I/O operations occur at the pins adjacent to the analog
input channel.
Note 6-2: The conversion time refers to the period from the time an instruction for starting a conversion process till the
time the conversion results register(s) are loaded with a complete digital conversion value corresponding to
the analog input value.
The conversion time is 2 times the normal-time conversion time when:
• The first AD conversion is performed in the 12-bit AD conversion mode after a system reset.
• The first AD conversion is performed after the AD conversion mode is switched from 8-bit to 12-bit
conversion mode.

Note8-1: The LVD reset level can be selected out of 7 levels only when the LVD reset function is enabled.
Note8-2: LVD reset voltage specification values do not include hysteresis voltage.
Note8-3: LVD reset voltage may exceed its specification values when port output state changes and/or when a large
current flows through port.
Note8-4: LVD is in an unknown state before transistors start operation.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the
instruction for starting the subclock oscillation circuit is executed and to the time interval that is required for the
oscillation to get stabilized after the HOLD mode is reset (see Figure 3):
Note: The components that are involved in oscillation should be placed as close to the IC and to one another as possible
because they are vulnerable to the influences of the circuit pattern.
