CPLD - Industry Standard Compatible

The ATF15xx CPLD Family comprises of Standard power as well as Low power devices that start at densities of 32 Macrocells (MC) and operate at speeds of upto 200 MHz. Microchip is one of the few CPLD suppliers that offer a 5 V core Operating voltage device (ATF15xxAS).

Microchip also offers a low power device (ATF15xxASL) as well as a low voltage ATF15xxASV that operates at 3.3 V. Microchip CPLDs can be used for I/O expansion as well as for memory control and Interfacing with different types of memories such as compact Flash or mobile SDRAM. For low power applications that are not speed sensitive, the ATF15xxASL/ASVL devices are recommended.

Key Features

  • Low Power - (5 µA) Consumption in Standby Mode
  • Logic Doubling - Implement Register latch and Combinatorial Latch in Single Macrocell
  • Programmable Pin Keeper circuit enables Bus interfacing
  • 10,000 Program/Erase cycles
