LC87F1A32A
CMOS IC
FROM 32K byte, RAM 2048 byte on-chip
8-bit 1-chip Microcontroller
with Full-Speed USB
Overview
The SANYO LC87F1A32A 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 32K-byte flash ROM (onboard
programmable), 2048-byte RAM, an onchip debugger, sophisticated 16-bit timers/counters (may be divided into 8-bit
timers), a 16-bit timer (may be divided into 8-bit timers 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, two channels of synchronous SIO interface (with automatic
block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full duplex),
a full-speed USB interface (function), an 12-bit 12-channel AD converter (12- or 8-bit resolution selectable), two
channels of 12-bit PWM, a system clock frequency divider, an infrared remote controller receiver circuit, and a 28-
source 10-vector interrupt feature.
Features
Flash ROM
• Capable of on-board-programming with wide range, 3.0 to 5.5V, of voltage source.
• Block-erasable in 128 byte units
• Writable in 2-byte units
• 32768 × 8 bits
RAM
• 2048 × 9 bits
Minimum Bus Cycle
• 83.3ns (CF=12MHz)
Note: The bus cycle time here refers to the ROM read speed.

USB Reference Power Option
When a voltage 4.5 to 5.5V is supplied to VDD1 and the internal USB reference voltage circuit is activated, the
reference voltage for USB port output is generated. The active/inactive state of reference voltage circuit can be switched
by the option select. The procedure for marking the option selection is described below.

• When the USB reference voltage circuit is made inactive, the level of the reference voltage for USB port output is
equal to VDD1.
• Selection (2) or (3) can be used to set the reference voltage circuit inactive in HOLD or HALT mode.
• When the reference voltage circuit is activated, the current drain increase by approximately 100μA compared with
when the reference voltage circuit is inactive.
Example 1: VDD1=VDD2=3.3V
• Inactivating the reference voltage circuit (selection (4)).
• Connecting VDD3 to VDD1 and VDD2.
