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
64 KB program memory address space in standard type; 1 MB extended program memory address
space in advanced type
64 KB data memory address space in standard type; 1 MB extended data memory address space in
advanced type
Boolean processor
Six-source, two-level interrupt capability in standard type; eight-source, two-level interrupt capability
in advanced type
Three 16-bit timer/counters
One full duplex serial channel
Built-in power management
Four 8-bit bidirectional and bit-addressable I/O ports in standard type; four 8-bit bidirectional and
bit- addressable I/O ports and one 8-bit bidirectional but parallel I/O port in advanced type
Packaged in 100-pin PQFP
