Product details
Overview
ATV2500BQL-25JC from Atmel is a high-density, UV-erasable programmable logic device (PLD) in 44-lead PLCC package, delivering 7 ns pin-to-pin delay, 416 product terms, 48 flip-flops, and 2 mA standby current at 5 V. It supports D- or T-type register configuration per macrocell and operates across industrial temperature range (–40°C to +85°C), used in legacy embedded control and digital logic replacement applications.
For engineers reviewing the ATV2500BQL-25JC datasheet, ATV2500BQL-25JC pinout, ATV2500BQL-25JC application, or ATV2500BQL-25JC equivalent, this page provides verified functional identity, confirmed PLCC-44 pin mapping, real-world timing specs (tCOS = 12 ns, fMAXS = 31 MHz), power behavior (ICC = 2 mA), and validated alternatives for industrial-grade reprogrammable logic upgrades.
Technical Context
The ATV2500BQL-25JC implements a fully connected universal AND-OR array with 38 array inputs feeding all 24 macrocells, each containing two independently configurable flip-flops (D/T-type), three sum terms combinable into up to 12 product terms, and dedicated product-term clocks per register. Its architecture enables buried combinatorial feedback via Q2 bypass and individual output enable per I/O.
It uses 0.65 µm CMOS EPROM technology with UV erasure (253.7 nm, ≥20 min), supports asynchronous reset and synchronous preload, and features power-up reset at VRST = 3.8–4.5 V with tPR = 600–1000 ns. Pin 4 and pin 26 are unconnected in PLCC/LCC variants, ensuring compatibility with ATV2500H/L pinouts.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATV2500BQ-25JC | Same PLCC-44 package, identical pinout, but higher ICC (30 mA vs. 2 mA) and no low-power optimization | Suitable for commercial-temp (0°C to 70°C) designs where power budget allows | Select only if legacy software toolchain requires BQ variant; otherwise ATV2500BQL-25JC offers superior power efficiency |
| ATV2500BL-25JC | Same low-power spec (2 mA ICC), but rated for commercial temp only (0°C to 70°C); lacks industrial qualification | Applicable in cost-sensitive consumer or lab equipment where ambient stays within commercial range | Choose when industrial temp rating is unnecessary and procurement favors BL family stock availability |
Compared with ATV2500BQ-25JC and ATV2500BL-25JC, the ATV2500BQL-25JC uniquely combines industrial temperature range, 2 mA standby current, and full PLCC-44 pin compatibility - making it the only option qualified for long-life embedded systems operating continuously at –40°C to +85°C with strict power constraints.

FAQ
What is the operating temperature range for ATV2500BQL-25JC?
The ATV2500BQL-25JC is specified for industrial operation from –40°C to +85°C ambient temperature. This rating is validated per DC and AC operating conditions tables and includes full functionality of all registers, I/O buffers, and timing parameters without derating. The device incorporates power-up reset circuitry that activates at VRST = 3.8–4.5 V, ensuring reliable initialization across this full range.
Does ATV2500BQL-25JC support T-type flip-flops?
Yes, the ATV2500BQL-25JC supports both D- and T-type flip-flops per macrocell - a core feature of the ATV2500B family. Each of its 48 registers can be individually configured via programming bits, enabling efficient implementation of JK and SR flip-flops. This capability is documented in the Functional Logic Diagram Description and Output Configuration tables, and applies identically to ATV2500BQL-25JC as part of the ATV2500B(Q)(L) family.
What is the significance of "L" in ATV2500BQL-25JC?
The "L" in ATV2500BQL-25JC denotes the low-power variant of the ATV2500BQ family, characterized by 2 mA typical standby current (ICC) at 5 V - a 15× reduction versus the standard ATV2500BQ (30 mA). This "L" suffix reflects optimized EPROM cell design and reduced leakage, confirmed in the DC Characteristics table and explicitly tied to the ATV2500BQL part number in the Ordering Information section.
Is pin 4 connected on ATV2500BQL-25JC?
No, pin 4 is not connected on ATV2500BQL-25JC. As stated in the "Note" on page 1 of the datasheet: "For ATV2500BQ and ATV2500BQL (PLCC/LCC package only) pin 4 and pin 26 connections are not required." This NC status is specific to PLCC and LCC packages and is a deliberate design choice to ensure backward compatibility with ATV2500H/L pinouts - confirmed in the Pin Configurations diagram and functional notes.
How does the power-up reset function in ATV2500BQL-25JC?
The ATV2500BQL-25JC performs automatic power-up reset: when VCC crosses VRST (3.8–4.5 V), all 48 registers reset to low state after tPR = 600–1000 ns. This behavior is guaranteed across the industrial temperature range and requires monotonic VCC rise and adherence to input setup times before clock activation. The reset mechanism is intrinsic to the silicon and does not require external circuitry - a documented feature in the Power-up Reset section.
