W78C58B Description
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 advanced type supports the functions of the W78C438 and W78C458.
W78C58B Key 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
- 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 bined emulation program and data memory in a 128 KB SRAM
- Provides internal S1 state clock timing signal for easy creation of the emulation contro
