* Question

What are the series of Altera CPLDs?

* Answer

Altera (now part of Intel) offers a range of Complex Programmable Logic Devices (CPLDs) under several product series, each targeting different applications and performance levels. Here’s a summary of the major Altera CPLD series:

1. MAX® 3000 Series
– Key Features:
– Based on EEPROM technology.
– Low power consumption.
– Simple design suitable for general-purpose applications.
– Up to 512 macrocells.
– Applications:
– Glue logic.
– Interface bridging.
– Simple control logic.

2. MAX® 7000 Series
– Key Features:
– Based on EEPROM technology.
– High-density CPLDs with up to 512 macrocells.
– Supports in-system programmability (ISP).
– High performance and fast propagation delays.
– Applications:
– Address decoding.
– State machines.
– Bus interface.

3. MAX® II Series
– Key Features:
– Non-volatile CPLD using Flash technology.

5. MAX® 10 Series
– Key Features:
– Non-volatile FPGA-like features but marketed as part of the CPLD ecosystem.
– Integrated ADCs and additional logic resources.
– Flash memory-based architecture with instant-on functionality.
– Supports multiple voltage standards.
– Applications:
– Advanced control systems.
– Data acquisition.
– Logic consolidation.

6. Older and Specialized CPLD Families
– MAX 9000 Series (discontinued):
– Early CPLD series designed for high-density logic.
– MAX 5000 Series:
– Early-era CPLDs with limited adoption.

Key Considerations When Selecting a CPLD Series:
– Power Consumption: For battery-powered or portable devices, the MAX II or MAX V series is ideal due to their low power consumption.
– Performance: For high-speed or advanced applications, MAX V and MAX 10 are better suited.
– Density: Depending on the number of macrocells or complexity of the design, MAX 7000 or MAX V may be more appropriate.
– Cost: For cost-sensitive applications, MAX II and MAX V series provide affordable solutions.
