The result is a simple and flexible solution for embedded designs. PSD devices combine many of the peripheral functions found in MCU based applications. Table 1 summarizes all the devices in the PSD834F2, PSD853F2, PSD854F2. The CPLD in the PSD devices features an opti- mized macrocell logic architecture. The PSD mac- rocell was created to address the unique requirements of embedded system designs. It al- lows direct connection between the system ad- dress/data bus, and the internal PSD registers, to simplify communication between the MCU and other supporting devices. The PSD device includes a JTAG Serial Program- ming interface, to allow In-System Programming (ISP) of the entire device. This feature reduces de- velopment time, simplifies the manufacturing flow, and dramatically lowers the cost of field upgrades. Using ST’s special Fast-JTAG programming, a de- sign can be rapidly programmed into the PSD in as little as seven seconds. The innovative PSD8XXFX family solves key problems faced by designers when managing dis- crete Flash memory devices, such as: – First-time In-System Programming (ISP) – Complex address decoding – Simultaneous read and write to the device. The JTAG Serial Interface block allows In-System Programming (ISP), and eliminates the need for an external Boot EPROM, or an external program- mer. To simplify Flash memory updates, program execution is performed from a secondary Flash memory while the primary Flash memory is being updated. This solution avoids the complicated hardware and software overhead necessary to im- plement IAP. ST makes available a software development tool, PSDsoft Express, that generates ANSI-C compli- ant code for use with your target MCU. This code allows you to manipulate the non-volatile memory (NVM) within the PSD. Code examples are also provided for: – Flash memory IAP via the UART of the host MCU – Memory paging to execute code across several PSD memory pages – Loading, reading, and manipulation of PSD macrocells by the MCU.
