GENERAL DESCRIPTION
The W78958B is an 8-bit emulation microcontroller that supports emulation for the Winbond W78C51 family of products, including the W78C31, W78C32, W78C51, W78C52, W78C154*, W78C58, W78C438, and W78C458. It is designed to support real-time (up to 40 MHz) emulation tools, such as in-circuit emulators (ICEs).
FEATURES
• 8-bit CMOS emulation microcontroller
• Real-time emulation at up to 40 MHz
• Convenient emulation chip for ICE market
• Two types: standard type and advanced type
• Standard type supports emulation for the W78C31, W78C32, W78C51, W78C52, W78C154*, and W78C58
• Advanced type supports emulation for the W78C438, and W78C458
• In emulation mode, allows direct access to SFRs/PC and internal RAM
• Allows ICE makers to access external program/data memory easily
• Supports switching signals between internal and external ROM
• Supports combined emulation program and data memory in a 128 KB SRAM
• Provides internal S1 state clock timing signal for easy creation of the emulation control signals
• Fully static design
• 256-byte on-chip scratchpad RAM
