Why Choose the ATF1508AS-15QI100?
✅ High Logic Density in a Compact Package
With 128 macrocells and up to 8,000 usable gates, the ATF1508AS is ideal for logic-intensive applications that previously required multiple smaller CPLDs or low-end FPGAs.
✅ Zero Power-on Configuration Delay
Unlike SRAM-based FPGAs that require an external configuration memory and boot time, this EEPROM-based CPLD has instant-on capabilities, making it perfect for mission-critical and deterministic systems.
✅ In-System Programmability (ISP)
Supports JTAG-based in-system programming, which simplifies firmware updates and debugging during development and field operation — a significant benefit for OEMs with long product life cycles.
✅ Industrial-Grade Reliability
Its operating temperature range from -40°C to +85°C ensures stable performance in harsh environments such as automotive engine control, aerospace subsystems, or outdoor telecom cabinets.
