We are looking at implementing a hardware security token with Secure Element (SE) with JavaCard smartcard connected to Android Phone over USB cable. In this design Android phone will be acting in a "USB host" mode.

Looking for a list of SE chips or smartcard manufacturers who provide Secure Element chip in a USB form factor.

Thank you!

Here is another chip from STi - ST23YT66 - Smartcard MCUwith USB and SPI interfaces and 66 KBytes EEPROM. This chip has been used in Ledger bitcoin wallet, and in some FIDO U2F tokens

Specs for ST23YT66 chip

More STi chips from ST23 family

The ST23YT66 product is a serial access microcontroller specially designed for secure smartcard applications. It is based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes linear addressing space. It is manufactured using an advanced highly reliable ST CMOS EEPROM technology. The ST23YT66 is a secure USB microcontroller based on the ST23 core architecture. Its high security level and versatile communication interfaces address user identification functions for computer or network access or for computer-based local or remote applications. The ST23YT66 features a USB full-speed interface for communication with computers as well as various I/Os and an SPI bus for user interfaces (keyboards, displays, etc.).

WARNING: JavaCard is nowhere mentioned, and it looks like this chip has a proprietary dev environment:

Development environment

Development tools for smartcard products include a complete range of hardware systems and software tools from STMicroelectronics and third-party tool suppliers. The range of tools includes solutions to help you to develop and debug your application and evaluate smartcard products and their peripherals. An Integrated Development Environment (IDE), the ST Visual Develop (STVD), provides a set of tools for developing embedded applications. This interface manages the project configuration, code edition, code generation and program debugging. A Smartcard ICS emulator (SCICS) is available for developing and validating your application code. All the information needed to generate the application code and personalization will be collected in a delivery file (.DLV extension). This file is created using the Delivery menu of the STMicroelectronics configuration software tool, SCOOL.
