LC87BK04A
CMOS IC
8K/6K/4K-byte ROM and 256-byte RAM integrated
8-bit 1-chip Microcontroller
Overview
The SANYO LC87BK08A/06A/04A 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/6K/4K-byte ROM, 256-byte
RAM, 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, an
asynchronous/synchronous SIO interface, a 12-bit/8-bit 8-channel AD converter, a system clock frequency divider, an
internal reset and a 15-source 9-vector interrupt feature.

Power Pin Treatment Recommendations (VDD1, VSS1)
Connect bypass capacitors that meet the following conditions between the VDD1 and VSS1 pins:
Connect among the VDD1 and VSS1 pins and bypass capacitors C1 and C2 with the shortest possible heavy lead
wires, making sure that the impedances between the both pins and the bypass capacitors are as possible (L1=L1’ ,
L2=L2’).
Connect a large-capacity capacitor C1 and a small-capacity capacitor C2 in parallel.
The capacitance of C2 should approximately 0.1μF.
