Hardware Feature Configuration
4.1
Microcontroller
The AI7933CLD features an ARM® Cortex-M33 processor, which is the most energy efficient ARM®
processor currently available. It supports the clock rates up to 200MHz when core power is 0.7V and
300MHz when core power is 0.8V. The MCU executes the Thump-2 instruction set for optimal
performance and code size, including hardware division, single cycle multiplication and bit-field
manipulation. The AI7933CLD includes a Memory Protection Unit (MPU) in Cortex-M33 MCU to detect
unexpected memory access and provides other memory protection features. The AI7933CLD also
includes FPU in Cortex-M33 MCU.
4.2
Power supply
EK-AI7933CLD supports two types of power supply.
1)
Power up with a micro-USB connector.
An on-board switching regulator provides voltage of 3.3V for the EK-AI7933CLD, if the power is
supplied from an on-board micro-USB connector CON8 (Figure 2). This supply can be isolated from the
switching regulator using the jumpers.
Note: that the jumpers J2, J3, J4, J5, J27 pin1 and pin2. JP1, JP2, JP5 pin1 and pin2 are required to be
set on. More details on the jumpers can be found in Table 1.
