ARM720T, ARM7EJ-S, ARM7TDMI and ARM7TDMI-S
The ARM7 family is a range of low-power 32-bit RISC microprocessor cores optimized for cost and power-sensitive applications.
Introduced in 1994, the ARM7 family continues to be used in a variety of designs, but newer and more demanding designs are
increasingly making use of latest ARM processors such as the Cortex-M0 and Cortex-M3 both of which offer several significant
enhancements over the ARM7 family.
- The ARM Cortex™-M3 32-bit processor has been specifically developed to provide a high-performance, low-cost platform for a broad range of applications including
microcontrollers, automotive body systems, industrial control systems and wireless networking. The Cortex-M3 processor provides
outstanding computational performance and exceptional system response to interrupts while meeting low cost requirements through
small core footprint, industry leading code density enabling smaller memories, reduced pin count and low power consumption.
- The ARM® Cortex™-M0 processor is the smallest, lowest power and most energy-efficient ARM processor available. The exceptionally small silicon area, low
power and minimal code footprint of the processor enables developers to achieve 32-bit performance at an 8-bit price point,
bypassing the step to 16-bit devices.
The ARM7 family offers up to 130MIPs (Dhrystone2.1) and incorporates the Thumb 16-bit instruction set. The family consists
of the ARM7TDMI, ARM7TDMI-S and ARM7EJ-S processors, each of which was developed to address different market requirements:-
- Integer processor
- Synthesizable version of the ARM7TDMI processor
- Synthesizable core with DSP and Jazelle® technology enhancements for Java acceleration
- Cached core with Memory Management Unit (MMU) supporting operating systems including Windows CE, Palm OS, Symbian OS and Linux
Applications
- Personal audio (MP3, WMA, AAC players)
- Entry level wireless handsets
- Two-way pagers
