ARM7TDMI
ARM 32-bit RISC core with 16-bit system costs
The ARM7TDMI core is a 32-bit embedded RISC processor delivered as a hard macrocell optimized to provide the best combination of performance, power and area characteristics. The ARM7TDMI core enables system designers to build embedded devices requiring small size, low power and high performance.

The ARM7 family also includes the ARM7TDMI-S macrocell, which has been developed to address different market requirements.
The ARM7TDMI core is available via the ARM Foundry Program
Applications:
  • Personal audio (MP3, WMA, AAC players)
  • Entry level wireless handset
  • Pager
  • Ink-jet/bubble-jet printer
  • Digital still camera
Features:

  • 32/16-bit RISC architecture (ARM v4T)
  • 32-bit ARM instruction set for maximum performance and flexibility
  • 16-bit Thumb instruction set for increased code density
  • Unified bus interface, 32-bit data bus carries both instructions and data
  • Three-stage pipeline
  • 32-bit ALU
  • Very small die size and low power consumption
  • Fully static operation
  • Coprocessor interface
  • Extensive debug facilities:
    • EmbeddedICE-RT real-time debug unit
    • JTAG interface unit
    • Interface for direct connection to Embedded Trace Macrocell (ETM)
Benefits:
  • Generic layout can be ported to specific process technologies
  • Unified memory bus simplifies SoC integration process
  • ARM and Thumb instructions sets can be mixed with minimal overhead to support application requirements for speed and code density
  • Code written for ARM7TDMI-S is binary-compatible with other members of the ARM7 Family and forwards compatible with ARM9, ARM9E, ARM10 families
  • Small die size reduces overall SoC area, cost and power consumption
  • Static design and lower power consumption are essential for battery-powered devices
  • Instruction set can be extended for specific requirements using coprocessors
  • EmbeddedICE-RT and optional ETM units enable extensive, real-time debug facilities
