TO136 - certified secure element for end-to-end IoT and industry 4.0 security

The TO136 is the lowest power certified tiny secure element in the market. Coming with a fully customisable personalisation scheme and command-set, starting at the lowest volumes in the industry, the TO136 is the most flexible tamper-resistant companion-chip for connected objects, sensors, actuators, gateways and machines. The hardware is banking-grade certified according to the EMVco standard (Europay – Mastercard – Visa) and runs cryptography algorithms stored in its highly protected flash-memory allowing the deployment of future-proof solutions with remotely upgradable security schemes while deployed in the field.
