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.

■ Single Supply Voltage:
– 5 V±10% for PSD9xxF2
– 3.3 V±10% for PSD9xxF2-V
■ Up to 2Mbit of Primary Flash Memory (8 uniform sectors)
■ 256Kbit Secondary Flash Memory (4 uniform sectors)
■ Up to 256Kbit SRAM
■ Over 2,000 Gates of PLD: DPLD
■ 27 Reconfigurable I/O ports
■ Enhanced JTAG Serial Port
■ Programmable power management
■ High Endurance:
– 100,000 Erase/Write Cycles of Flash Memory
– 1,000 Erase/Write Cycles of PLD
