PSD813F1-A
Flash In-System-Programmable
Microcontroller Peripherals
The PSD813F1 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. PSD813F1 devices combine many of
the peripheral functions found in MCU based applications:
• 1 Mbit of Flash memory
• A second EEPROM memory
• Over 3,000 gates of Flash programmable logic
• SRAM
• Reconfigurable I/O ports
• Programmable power management.
PSD813F1 devices integrate an optimized “microcontroller macrocell” logic architecture
called the Micro⇔CellTM. 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.
