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.

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:

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.
