PALCE610H-20/BLA

Overview

The PALCE610H-20/BLA is a high-performance Complex Programmable Logic Device (CPLD) from Advanced Micro Devices, belonging to the PALCE610 family. It features 10 macrocells and supports up to 13 I/O pins within a 40-pin PLCC package. The device operates with a maximum propagation delay of 20 ns and is rated for commercial temperature ranges, specifically from 0°C to +70°C. It utilizes advanced EEPROM technology for non-volatile configuration, allowing for in-system reprogrammability without the need for UV erasure.

Feature Summary

• Contains 10 macrocells with flexible logic array block architecture
• Supports up to 13 general-purpose I/O pins
• Maximum propagation delay of 20 nanoseconds
• Non-volatile EEPROM memory for persistent configuration storage

Applications

• Address decoding and bus arbitration in embedded systems
• Simple state machine implementation for control logic
• Interface translation between different voltage domains or protocols
• Replacement for legacy GAL devices in existing designs

Procurement Notes

Verify the specific suffix 'BLA' against official AMD documentation to confirm package type and temperature grade accuracy. Ensure that the source document explicitly lists this part number as an active or obsolete component rather than a generic placeholder. Cross-reference the 20ns speed grade with the datasheet timing parameters to confirm performance specifications match the intended application requirements.

Selection Notes

Select this component when a design requires moderate logic density with non-volatile configuration capabilities. The 10-macrocell count is suitable for simple control functions rather than complex data processing. Consider the 20ns delay for applications operating at clock frequencies below 50 MHz. Verify that the 40-pin PLCC footprint is compatible with the target PCB layout constraints.

Part Context

This device is part of the PALCE610 series, which serves as a drop-in replacement for many older GAL (Generic Array Logic) devices. It bridges the gap between simple discrete logic and larger FPGAs, offering ease of programming via standard ISP tools. The EEPROM technology distinguishes it from fuse-based PLDs by allowing unlimited reprogramming cycles.

Replacement Considerations

Direct pin-to-pin replacements may include other PALCE610 variants with different speed grades (e.g., 15ns or 25ns). Verify electrical compatibility if substituting with higher or lower speed versions. No direct cross-model substitutes from other manufacturers are publicly confirmed without specific equivalence documentation.
