eZVision 200 Television Controllers with OSD
PS010703-0502
1
The Z90233/Z90234 and Z90231 are the ROM and OTP versions of the eZVision
200 television controller with OSD. Based on ZiLOG’s powerful Z8 architecture,
the Z90233/Z90234 and Z90231 contain 24 KB of program memory. The following
enhanced features are included:
•
Flexible inter-row spacing
•
Higher character cell resolution (14 x 18)
•
Background mesh effect
•
Dedicated infrared capture registers
•
On-chip analog-to-digital converter
•
Hardware master mode I

C interface
The familiar Z8 architecture, in combination with these advanced features, makes
the eZVision 200 an ideal choice for midrange televisions in both PAL and NTSC
markets.
The eZVision 200 family consists of three basic device types:
•
The Z90233 and Z90234 masked ROM
•
The Z90231 OTP
•
The Z90239 In-Circuit Emulator (ICE) chip
The OTP supports a field-programmable 24 KB program ROM. The ICE chip is
used in the Z90239 emulator and protopak. The Z90233/Z90234 masked ROM
supports a 16/32-KB system ROM (selectable through a mask option).
The eZVision 200 family takes full advantage of the Z8 microcontroller’s expanded
register file space to offer greater flexibility in OSD creations that simulate bitmap
graphics, icons, and animation.
