SUMMARY DESCRIPTION 

The PSD8XXFX family of memory systems for mi-crocontrollers(MCUs) brings In-System-Program-mability(ISP) to Flash memory and programmable logic. 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 optimized macrocell logic architecture. The PSD macrocell was created to address the unique requirements of embedded system designs. It allows direct connection between the system address/data bus, and the internal PSD registers, to simplify communication between the MCU and other supporting devices.

The PSD device includes a JTAG Serial Programming interface, to allow In-System Programming (ISP) of the entire device. This feature reduces development time, simplifies the manufacturing flow, and dramatically lowers the cost of field upgrades. Using ST's special Fast-JTAG programming,a design 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 discrete 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 programmer. 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 implement IAP.
ST makes available a software development tool, PSDsoft Express, that generates ANSI-C compli The PSD device indudes a ITAG SerialProgram-antcode orUe' wyrurgef ico. Tis ode ming interface, to allow In-System Programming allows you to manipulate the non-volatile memory (ISP) of the entire device. This feature reduces developmen time, simplies the manuacuing fiow, NWM) within the PSD. Code examples are also provided for: 

 -Flash memory IAP via the UART of the host sign can be rapidly programmed into the PSD in as MCU little as seven seconds.

 -Memory paging to execute code across several PSD memory page 

 -Loading, reading, and manipulation of PSD macrocells by the MCU.
