Features & Applications

The STR710FZ2T6 is a ARM7TDMI 32-bit microcontroller with a full peripheral set, 256 kB Flash +16 kB Data Flash, 64 kB RAM, temperature range of -40 °C to 85 °C, in a 144Pin LQFP package.

The STEVAL-IPC001V1 is an integrated system to allow designers to evaluate a complete and ready-to-use cash register application. It is intended for the low to medium-end POS/cash register market and consists of a hardware board, firmware and PC GUI (graphical user interface). At the core of the board, the STR710FZ2 microcontroller controls all tasks of the system.

The STR710FZ2 gives the board a wide scope of communication capabilities, incorporating four UARTs, one 10T-LAN, one PS/2 interface and various IC and SPI connectors. The firmware is a modular suite which simultaneously implements a typical cash register application and provides a suitable library to develop an optimized and customized final application. The PC GUI is a user-friendly PC application to manage both goods information and board parameters through a dedicated protocol.
