XC95216-20HQ208C

XC95216-20HQ208C Description

The XC95216-20HQ208C is a high-performance Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, designed for flexible digital logic integration. This 216-macrocell device operates at a 5V internal supply voltage (4.75V–5.25V) and delivers a maximum propagation delay of 20ns, making it suitable for medium-speed logic applications. Packaged in a 208-pin HQFP (Quad Flat Package), it offers 166 I/O pins and 12 logic blocks, providing ample resources for complex state machines, glue logic, and interface bridging. Though now obsolete, it remains a reliable choice for legacy systems requiring in-system programmability (ISP) with 10,000+ program/erase cycles.

XC95216-20HQ208C Features

• High Logic Density: 216 macrocells and 4,800 gates enable robust logic implementation.
• Fast Performance: 20ns max delay ensures efficient timing for control applications.
• Flexible I/O: 166 programmable I/Os support versatile interfacing.
• In-System Programmable (ISP): Allows field updates with 10K+ cycle endurance.
• 5V Operation: Compatible with legacy TTL/CMOS systems.
• Surface-Mount HQFP Package: Optimized for space-constrained PCB designs.
• Wide Temperature Range: Operates at 0°C to 70°C, suitable for industrial environments.

XC95216-20HQ208C Applications

• Legacy System Upgrades: Replaces discrete logic in older 5V-based designs.
• Communication Interfaces: Handles protocol bridging (UART, SPI, I2C).
• Industrial Control: Implements state machines for automation systems.
• Embedded Systems: Glue logic for processors and peripherals.
• Test Equipment: Customizable logic for diagnostic tools.

Conclusion of XC95216-20HQ208C

The XC95216-20HQ208C balances logic density, speed, and reprogrammability, making it ideal for 5V systems needing reliable CPLD functionality. While obsolete, its ISP capability and high I/O count ensure continued utility in maintenance and legacy upgrades. Engineers valuing proven performance over cutting-edge tech will find it a pragmatic solution.
