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 and ARM7EJ-S cores and the ARM720T macrocell, each of which has been developed to address different market requirements.

The ARM7TDMI core is available via the ARM Foundry Program
