LC87FBL08A
CMOS IC
8K-byte FROM and 256-byte RAM integrated
8-bit 1-chip Microcontroller
http://onsemi.com
Overview
The LC87FBL08A 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, an asynchronous/synchronous SIO interface, two 12-bit PWM
channels, a 12-bit/8-bit 11-channel AD converter, a system clock frequency divider, an internal reset and a 17-source
9-vector interrupt feature.
Features
Flash ROM
• Capable of On-board programming with wide range (2.7 to 5.5V) of voltage source.
• Block-erasable in 128 byte units
• Writable in 2-byte units
• 8192 × 8 bits
RAM
• 256 × 9 bits
Minimum Bus Cycle
• 83.3ns (12MHz at VDD=2.7V to 5.5V)
Note: The bus cycle time here refers to the ROM read speed.

Note1: On-board-programmer from FSG (AF9101/AF9103) and serial interface driver from Our company (SIB87)
together
can give a PC-less, standalone on-board-programming capabilities.
Note2: It needs a special programming devices and applications depending on the use of programming environment.
Please ask FSG or Our company for the information.

Note 1: The control of the presence or absence of the programmable pull-up resistors for port 0 and the switching
between low-and high-impedance pull-up connection is exercised in nibble (4-bit) units (P00 to 03 or
P04 to 07).
