with Full-Speed USB
The SANYO LC87F1G64A 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 64K-byte flash ROM (onboard
programmable), 3072-byte RAM, an on-chip debugger, a sophisticated 16-bit timers/counters (may be divided into 8-bit
timers), 16-bit timers/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with a
prescaler, a base timer serving as a time-of-day clock, two synchronous SIO interface (with automatic block transmit/
receive function), an asynchronous/synchronous SIO interface, a UART interface (full duplex), a Full-Speed USB
interface (function controller), an 8-bit 12-channel AD converter, two 12-bit PWM channels, a system clock frequency
divider, ROM correction function, and a 32-source 10-vector address interrupt feature.

Interrupts
•
32 sources, 10 vector addresses
1) Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt requests of
the level equal to or lower than the current interrupt are not accepted.
2) When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest level
takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector
address takes precedence.
