Power Supply
The ADuCM3029 can run from a core supply voltage between 1.8 and 3.3 volts. By default the core is fed from the 3.3v supply but the adjustable regulator on the CW308T can be used to set any viable core voltage. Sometimes power analysis is more viable at different supply voltages.
Cryptographic Accelerator
As described in the ADuCM3027/3029 Data Sheet[1], The cryptographic accelerator is a 32-bit APB DMA capable peripheral. There are two 32-bit buffers provided for data input/output operations. These buffers read in or read out 128 bits in four data accesses. Big endian and little endian data formats are supported, as are the following modes:
- Electronic code book (ECB) mode—
- AES mode (128 and 256)
- Counter (CTR) mode
- Cipher block chaining (CBC) mode
- Message authentication code (MAC) mode
- Cipher block chaining-message authentication code (CCM/CCM) mode
- SHA-256 mode
Programming
An external programmer is needed for this target. The SAM4L has an internal bootloader you can use via an external serial port, which is not yet supported directly by the ChipWhisperer-Capture software.
Schematic
See GIT Repo for PDF of schematic.
Board Layout
