Description

The PSD813F2/3/4/5, 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. PSD8XXFX devices combine many of the peripheral functions found in MCU based applications.

Table 1 summarizes all the devices in the PSD813F2/3/4/5,.

The CPLD in the PSD813F2/3/4/5, devices features an optimized macrocell logic architecture. The PSD macrocell was created to address the unique re-quirements of embedded system designs. It al- lows direct connection between the system address/data bus, and the internal PSD8XXFX registers, to simplify communication between the MCU and other supporting devices.

The PSD8XXFX device includes a JTAG Serial Programming interface, to allow In-System Pro- gramming (ISP) of the entire device. This feature reduces development time, simplifies the manu-facturing flow, and dramatically lowers the cost of field upgrades. Using ST's special Fast-JTAG pro-gramming, a design can be rapidly programmed into the PSD8XXFX in as little as seven seconds.

The innovative PSD813F2/3/4/5, 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 PSD813F2/3/4/5,. Code examples are also provided for:
Flash memory IAP via the UART of the host MCU
Memory paging to execute code across several PSD8XXFX memory pages
Loading, reading, and manipulation of PSD8XXFX macrocells by the MCU.
