LC87F40C8A
Overview
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
The SANYO LC87F40C8A is a closed caption TV controlling 8-bit microputer 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 patible OSD, a system clock frequency divider, ROM correction function, an on-chip debugger, and onboard programming facilities.
