The devices provides an ideal performance and reliability solution for consumer and industrial television applications. The Z90209 is the ROMless In-Circuit Emulation (ICE )Chip version of the Z90200 Digital Television Controller Family used in emulators and development boards. The device features an 8-bit internal data path controlled by a Z8 microcontroller, On-Screen Display (OSD) logic circuits, and Pulse Width Modulators (PWM). On-chip peripherals include two register mapped I/O ports (Ports 2 and Port 3), interrupt control logic (one software, two external and three internal interrupts) and a standby mode recovery input port (Port 3, pin P30). The OSD control circuits support ten rows by 24 columns of characters. The character color is specified by character. The OSD inter-row spacing is variable a...
