W78958B 8-BIT EMULATION MICROCONTROLLER 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). The W78958B is packaged in a 100-pin PQFP and is available in two different types, standard and advanced. The standard type supports the functions of the W78C31, W78C32, W78C51, W78C52, W78C154*, and W78C58. The advanced type supports the functions of the W78C438 and W78C458. Both types can be operated in two modes, normal and emulation. In normal mode, the W78958B runs freely, like the W78C51 family of products.
