ChipWhisperer Embedded Security Analysis Tools Capture Hardware NewAE Technology CW1101: ChipWhisperer-Nano NewAE Technology Inc. Product Datasheet newae.com e CTh hipWhisperer-Nano is the lowest cost platform for performing side-channel power analysis attacks in training and educational environments. This device has a smaller subset of features compared to the ChipWhis- perer-Lite or -Pro, but still allows you to perform many of the tutorials and demos. e uTh se of synchronous sampling ensures that this low-cost device can be used for performing real power analysis of algorithms and devices. The built-in target is a STM32F030F4P6 which has 16KB of FLASH and 4KB of SRAM. It is possible to cut the included target off and attach to external targets, such as the CW308 base-board. This al- lows an external clock to be routed to the on-board ADC for measuring of external devices. Product Highlights 8-bit ADC with 20 MS/s sampling rate and fixed-gain front-end allows measurements of on-board and some external targets. Advanced synchronous clock locking logic samples target power on related clock edges, drastically reducing sample rate requirements compared to power analysis performed with regular oscilloscopes. Single-board solution ideal for teaching and training environments, and design of boards allows easy separation of tar- get for future expansion. Programmers for STM32Fx (serial bootloader) targets built in, meaning no external equipment required. Note this platform has limited VCC-glitching capability and no clock glitching capability, instead primarily focusing on side-channel power analysis.

Target Device STM32F030F4P6 or STM32F070 Programming Protocols STM32Fx Bootloader Synchronous Architecture Power Measurement (using scope). Target Device Clock. ChipWhisperer Sample Clock. Our ChipWhisperer capture hardware can use a target device clock to sample at desired point(s) during the clock cycle. This ensures sample points are directly related to the digital clock which generates the signals of interest. The result is many devices can be successfully attacked with 5-100x slower sample clock compared to a regular oscilloscope. CW1101 Datasheet 2 Last Update: 2019-MAY-30
