LC87F5864B
CMOS IC
FROM 64K byte, RAM 2048 byte on-chip
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F5864B is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of
100ns, integrates on a single chip a number of hardware features such as 64K-byte flash ROM (onboard programmable),
2048-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), four 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 (with automatic block
transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex), an 8-bit
11-channel AD converter, two 12-bit PWM channels, a system clock frequency divider, and a 23-source 10-vector interrupt
feature.

Note 1 : Programmable pull-up resistors for port 0 are controlled in 4-bit units (P00 to 03, P04 to 07).
*1 : Connect the IC as shown below to minimize the noise input to the VDD1 pin.
Be sure to electrically short the VSS1, VSS2, and VSS3 pins.

For backup *2
LSI
VDD1
VDD2
VDD3
VSS1 VSS2 VSS3
*2 : The internal memory is sustained by VDD1. If none of VDD2 and VDD3 are backed up, the high level output at
the ports are unstable in the HOLD backup mode, allowing through current to flow into the input buffer and thus
shortening the backup time.
Make sure that the port outputs are held at the low level in the HOLD backup mode.
