Preliminary
8-BIT SINGLE CHIP MICROCONTROLLER
LC86F3548A
LC86F3548A
8-bit Single Chip Microcontroller with on-chip 64K-byte Flash Memory (ROM 48K -byte + CGROM 16K-
byte), on-chip 640-byte RAM and 176 × 9 bit OSD RAM
Overview
The LC86F3548A is a CMOS 8-bit single chip microcontroller with flash memory for the LC863500 series.
This microcontroller contains the following on-chip functional blocks:
- CPU : Operable at a minimum bus cycle time of 0.424µs
- On-chip ROM capacity : 64K bytes Flash Memory
Program ROM : 48K bytes
CGROM :
16K bytes
- On-chip RAM capacity : 640 bytes
- OSD RAM : 176 × 9 bits
- On-screen display controller
- Four channels × 6-bit AD Converter
- Three channels × 7-bit PWM
- Two 16-bit timer/counters, 14-bit base timer
- IIC-bus compliant serial interface circuit (Multi-master type)
- ROM correction function
- 12-source 8-vectored interrupt system
- Integrated system clock generator and display clock generator
Only one X’tal oscillator (32.768kHz) for PLL reference is used for both generators
All of the above functions are fabricated on a single chip.
The program is rewritable by using the on-board writing system after the LSI has been installed on the
application board.

On-board writing system
LC86F3548A
The LC86F3548A has the On-board writing system. The program is renewable by using SANYO Flash On-
board
System after the LSI has been installed on the application board.
This system is composed of 4 types divided by the combination of mode setting pin and communication pin.
Each type system has to connect the 6 pins (VDD,VSS,RES, communication pins) with the interface board of
SANYO Flash On-board system.
It is necessary that the pins to be used for the rewriting system should be able to be separated from the
application board properly.
The system type is selected by the option setting program (Su86K.exe).

• Type 3 or 4 is selected : P30 is exclusive for the on-board system. This pin must always be pulled-down, so
this pin can’t be used for other applications.
• The loader program must be written into the ROM to use On-board writing system.
The loader program should be written into the ROM before the LSI has been installed on the board by the
the general purpose ROM programs.
When the option setting selects the this system to use, the loader program automatically links
on the user program linking.
Please ask to our sales persons before using On-board writing system.
Use of PROM Conversion board
When reading or writing data to the LC86F3548A using our exclusive conversion board (W86F3448D,
W86F3448M) general purpose PROM programs can be used.
(1) Name of conversion boards
- W86F3448D • • • DIP36S purpose
- W86F3448M • • • MFP36S purpose
(2) Available PROM programmers
The LC86F3548A does not support a silicon signature feature. Do not use the feature (automatic device
type selection) when programming this device. To avoid erasing the program, confirm the setting of the
protection for written program is active before using .
