Key Features
- PLA-type CPLD architecture with 24 macro cells and 38 inputs enabling complex combinational logic at up to 27 MHz
- 24 I/O lines and 13 dedicated inputs in a 40-pin DIP package for through-hole prototyping and legacy board replacement
- Non-volatile programmable logic with no JTAG BST, suitable for fixed-function industrial glue logic and address decoding applications
Applications
The ATV2500BQL-25PI is used in legacy industrial control systems and embedded designs requiring fixed combinational or sequential logic implemented in a CPLD. Its 24 macro cells and 27 MHz maximum clock frequency support address decoding, bus arbitration, and state machine implementations in retrofit or long-lifecycle boards. The 40-pin DIP package simplifies through-hole assembly and socketed replacement in field-serviceable equipment.

Frequently Asked Questions
How many macro cells and I/O lines does ATV2500BQL-25PI provide, and what clock speed does it support?
The ATV2500BQL-25PI provides 24 macro cells and 24 I/O lines, with 13 dedicated inputs and a maximum clock frequency of 27 MHz. This capacity supports moderately complex state machines and bus glue logic in industrial controllers where a small CPLD replaces multiple 74-series logic ICs.
For a legacy industrial board retrofit, what advantages does the ATV2500BQL-25PI 40-pin DIP package offer over a modern QFP CPLD?
The 40-pin DIP through-hole package allows the ATV2500BQL-25PI to be socketed for easy in-field replacement without soldering equipment. This is valuable in industrial retrofit projects where the PCB was originally designed for through-hole logic, and switching to a surface-mount QFP would require board redesign and new assembly tooling.
Is the ATV2500BQL-25PI in-system programmable, and what does that mean for production programming workflow?
The ATV2500BQL-25PI is not in-system programmable (ISP = NO) and lacks JTAG boundary scan. Programming must be done via a dedicated programmer before board assembly. This requires a separate programming step in the production workflow, which is common for older PLA-type CPLD families used in 27 MHz logic applications where ISP was not yet standard.
