SH-2A
The SH-2A is an upgrade to the SH-2 core. It was announced in early 2006.
At launch in 2007 the SH-2A based SH7211 was the world's fastest embedded flash microcontroller running at 160 MHz. It has later been superseded by several newer SuperH devices running at up to 200 MHz.
New features on the SH-2A core include:
- Superscalar architecture: execution of 2 instructions simultaneously.
- Harvard architecture
- Two 5-stage pipelines.
- 15 register banks for interrupt response in 6 cycles.
- Optional FPU
The SH-2A family today spans a wide memory field from 16kB up to and includes many ROM-less variations. The devices feature standard peripherals such as CAN, Ethernet, USB and more as well as more application specific peripherals such as motor control timers, TFT controllers and peripherals dedicated to automotive powertrain applications.
