DESCRIPTION
The FLASH+PSD family of memory systems for
microcontrollers (MCUs) brings In-SystemProgrammability (ISP) to Flash memory and
programmable logic. The result is a simple and
flexible solution for embedded designs.
FLASH+PSD devices combine many of the
peripheral functions found in MCU based
applications. FLASH+PSD provides a glueless
interface to most commonly-used ROMless
MCUs.
Table 2 summarizes all the devices in the M89
Family.
The FLASH+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 FastJTAG programming, a design can be rapidly
programmed into the FLASH+PSD.
The innovative FLASH+PSD family solves key
problems faced by designers when managing
discrete Flash memory devices, such as:
– Complex address decoding
– In-System (first-time) Programming (ISP)
– Concurrent EEPROM or Flash memory
programming (IAP).
The JTAG Serial Interface block allows In-System
Programming (ISP). Embedded dual-bank
memories eliminates the need for an external Boot

Sometimes computers try to be too clever for theirown good. Take this illustration for instance.
Just because somany of the labels are rotatedthrough ninety degrees, FrameMaker seems to
want to insist on telling the postscript file that I would find it more convenient to see this page
displayed inlandscape, rotated by ninety degrees. Well I wouldn’t. So I amputting inall this text
just to weight the average in this direction.
