Introduction
Flash In-System-Programmable
Microcontroller Peripherals
The PSD8XXF family of Programmable Microcontroller (MCU) Peripherals brings
In-System-Programmability (ISP) to Flash memory and programmable logic. The result is a
simple and flexible solution for embedded designs. PSD8XXF devices combine many of
the peripheral functions found in MCU based applications:
•
Up to 2 Mbit of Flash memory
•
A second Flash Boot memory
•
Over 3,000 gates of Flash programmable logic
•
Up to 256 Kbit SRAM
•
Reconfigurable I/O ports
•
Programmable power management.
PSD8XXF devices integrate an optimized “microcontroller macrocell” logic architecture
called the Micro⇔Cell
TM
. The Micro⇔Cell 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.
