LC87F40C8A
CMOS IC
Internal 128K-byte FROM (ROM/CGROM),
2048 byte RAM, 1024-byte CGRAM,
and 704×10-bit CRT Display RAM
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F40C8A is a closed caption TV controlling 8-bit microcomputer that, centered around a CPU running
at a minimum bus cycle time of 71ns, integrates on a single chip a number of hardware features such as 128K-byte flash
ROM (size-variable program ROM and CGROM), 2048-byte RAM, 1024-byte CGRAM, 704×10-bit CRT display RAM,
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, two 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), two channels of asynchronous/
synchronous SIO interface (bus mode selectable), a UART interface (full duplex), an 8-bit 8-channel AD converter, one
14-bit PWM channel, three 8-bit PWM channels, a closed caption data slicer, closed caption compatible OSD, a system
clock frequency divider, ROM correction function, an on-chip debugger, and onboard programming facilities.

On-board writing system
The LC87F40C8A 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 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 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 general purpose PROM 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.
