These parts feature larger system RAM and ROM options, together with a host of new features including a new color palette system, flexible inter-row spacing, higher character cell resolution, background mesh effect, dedicated I.R. capture registers, on-chip Analog-to-Digital conversion, and a hardware Master mode I2C interface. The familiar Z8 core in combination with these advanced features makes the Z9023X family an ideal choice for low to midrange televisions in both PAL and NTSC markets. The Z9023X family consists of three basic device types; ICE Chip (Z90239), ROM Mask Parts (Z90233/Z90234), and OTP Part (Z90231). The OTP (Z90231) supports field programmable 32KB system ROM. ICE Chip (Z90239) is used in Z90239 Emulator and ProtoPak. As described above, Z90233 supports 16KB system ROM and Z90234 supports 24KB system ROM for mask. The Z9021X family takes full advantage of the Z8's expanded register file space to offer greater flexibility in On Screen Display creation. Note: All signals with an overline, " ", are active Low. For example, B/: (WORD is active Low, only); %/W (BYTE is active Low, only).
