DESCRIPTION

The FLASH+PSD family of memory systems for microcontrollers (MCUs) brings In-System-Programmability (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.
