General

• The SH2 was first manufactured in October 1993. The die size is 7.59mm by 7.44mm with an .8 micron die process. For comparison, modern CPUs are measured in nanometers. One nanometer is 1/1000 the size of one micron. The CPU chip size is 5.45mm².
  
  

Functionality

• This chip directly supports the popular memory interface types, such as SDRAM, DRAM and Masked ROM. It includes a 32-bit fixed point multiplier and division unit for 3D calculations. The SH2 can be configured to support a dual-processor.
  
  

Power Consumption

• SH2 processors consume 400MHz at 5 volts. The operating voltage range can be between 2.7 volts to 5.5 volts. The clock frequency is 28.7MHz for a CPU throughput of 25 million instructions per second.
  
  

Architecture

• This processor has a 32-bit architecture, with 16 fixed length instructions and 16 general purpose registers, making it ideal for "C" language programming. The earliest SH2 had 4 kilobytes of cache for code pre-fetching. More advanced processors in the family had up to 32KB.
