This board supports the Analog Devices ADuCM3029 microcontroller. The mounted chip is the ADUCM3029BCPZ.
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.
As described in the ADuCM3027/3029 Data Sheet, 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
The ADuCM3029 supports a serial bootloader which is enabled by pulling down the PDIC pin on the CW308T. Details for using the serial bootloader can be found in the application note EE-381. Single wire debug (SWD) is also supported for programming and debugging.
