ST32H480数据手册ST中文资料规格书

描述 Description

The device is a serial access microcontroller designed for secure mobile applications. It incorporates the most recent generation of ARM processors for embedded systems. Its SecurCore® SC000™ 32-bit RISC core is built on the Cortex® M0 core with additional security features to help to protect against advanced forms of attacks. The SC000™ core brings great performance and excellent code density thanks to the Thumb®-2 instruction set. The CPU interfaces with the on-chip RAM, ROM and NVM via a 32-bit internal bus.

The high-speed, 480-Kbyte, embedded Flash memory introduces more flexibility to the system.

The device also offers a serial communication interface fully compatible with the ISO 7816-3 standard (T=0, T=1) for smartcard applications. In addition, it includes two general-purpose 16-bit timers, an ISO 3309 CRC calculation block and a watchdog timer. Finally, it has a hardware Data Encryption Standard (DES) accelerator that the user can use to optimize the application performance.

The device operates in the –25 to +85 °C temperature range, and the 1.8 V and 3 V supply voltage ranges. A comprehensive range of power-saving modes enables the design of efficient low-power applications.

The device is delivered in D18 micromodules. It is also available in wafers.
