Introduction
Preliminary Information
PSD913F2, PSD934F2,
PSD954F2
Configurable Memory System
on a Chip for 8-Bit Microcontrollers
The PSD9XX family of Programmable System Devices (for 8-bit microcontrollers) brings
In-System-Programmability (ISP) to Flash memory and programmable logic. The result is a
simple and flexible solution for embedded designs. PSD9XX devices combine many of the
peripheral functions found in MCU based applications:
Up to 2 Mbit of Flash memory
A secondary 256 Kbit Flash memory
Over 2,000 gates of Flash programmable logic
Up to 256 Kbit SRAM
Reconfigurable I/O ports
Programmable power management.
