Keil ST STR912FAW44 ARM MCU开发评估方案

Keil公司的MCBSTR9评估板适用于ST公司的STR91xMCU系列，用来产生和测试应用程序，包括了单片STR9系统的所有硬件元件，以开发目前和未来的产品。本文介绍了ST公司的STR91xFAxxx 主要特性，方框图以及MCBSTR9评估板主要特性，方框图，技术数据和电路图。

STR91xFA is a series of ARM-powered microcontrollers which combines a 16/32-bit ARM966E-S RISC processor core, dual-bank Flash memory, large SRAM for data or code, and a rich peripheral set to form an ideal embedded controller for a wide variety of applications such as point-of-sale terminals, industrial automation, security and surveillance, vending machines, communication gateways, serial protocol conversion, and medical equipment. The ARM966E-S core can perform single-cycle DSP instructions, good for speech processing, audio algorithms, and low-end imaging.

The STR91xFA is a SiP device, comprised of two stacked die. One die is the ARM966E-S CPU with peripheral interfaces and analog functions, and the other die is the burst Flash.

The two die are connected to each other by a custom high-speed 32-bit burst memory interface and a serial JTAG test/programming interface.
