Microcontrollers: 8-bit TV Microcontrollers LC874 Series

The LC874 Series 8-bit microcontrollers are centered around a CPU core that operaters with a minimum bus cycle time of 71ns and integrate an extensive set of peripheral functions on a single chip. These pheripheral functions include a 64KB or 128KB flash ROM (selectable between program ROM and CGROM sizes), 2048-byte RAM, 1024-byte CGRAM, 352×10-bit or 704×10-bit CRT display RAM, two high-functionality 16-bit timer/counters that can be divided and used as 8-bit timers, two 8-bit timers with internal prescalers, a clock time base timer, a high-speed clock counter, a synchronous SIO circuit that features an auto transfer function, two synchronous or asynchronous SIO channels (bus mode switching), a UART (full duplex), an 8-bit A/D converter, a PWM, a closed caption data slicer and an advanced OSD. The series has been developed as 8-bit microcomputers for closed caption television control.
