SUMMARY DESCRIPTION
The PSD family of memory systems for microcon-
trollers (MCUs) brings In-System-Programmability
(ISP) to Flash memory and programmable logic.
The result is a simple and flexible solution for em-
bedded designs. PSD devices combine many of
the peripheral functions found in MCU based ap-
plications.
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 PSD family solves key problems
faced by designers when managing discrete Flash
memory devices, such as:
– First-time In-System Programming (ISP)
– Complex address decoding
– Simulataneous 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.
