Product details
Overview
ATV2500BQ-25PC from Atmel is a high-density, UV-erasable programmable logic device (PLD) in a 40-pin plastic DIP package, delivering 7 ns pin-to-pin delay, 416 product terms in a fully connected logic array, and 48 flip-flops (two per macrocell) for complex state-machine and combinatorial logic implementation in industrial control and legacy system upgrades.
For engineers reviewing the ATV2500BQ-25PC datasheet, ATV2500BQ-25PC pinout, ATV2500BQ-25PC application, or ATV2500BQ-25PC equivalent, this device supports configurable D/T-type registers, individual product-term clocking per flip-flop, buried combinatorial feedback, and low-power standby current of 30 mA - critical for timing-critical, reprogrammable logic replacements in commercial-temperature embedded systems.
Technical Context
The ATV2500BQ-25PC implements a single universal AND-OR logic array with 38 array inputs (14 dedicated pins + 24 flip-flop outputs), where all inputs feed every macrocell. Each of its 24 macrocells contains 17 AND gates with 172 inputs, and three sum terms combinable into up to 12 product terms per output without speed penalty.
It supports dual-register architecture per macrocell (D- or T-type selectable), independent asynchronous reset and clock product terms per flip-flop, and configurable output enable with eight synchronous preset terms distributed in 2/4 pattern across macrocell groups - enabling efficient implementation of counters, finite-state machines, and bi-directional I/O interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 25 ns - defines maximum combinational path speed for logic synthesis targeting setup/hold compliance at ≤31 MHz external feedback clocking. |
| Pin-to-Pin Clock-to-Output (tCOS) | 12 ns - determines minimum clock period for registered output timing in synchronous designs using input-pin clocking. |
| Standby Supply Current (ICC) | 30 mA - enables low-power operation in idle states while maintaining full reprogrammability and UV-erase capability. |
| Logic Density | 2500 usable gates - achieved via 416-product-term fully connected array and 48 flip-flops, supporting high gate utilization (>80%) in compact 40-pin DIP footprint. |
| Operating Voltage | 5 V ±5% - compatible with standard TTL/CMOS logic families and legacy 5 V system rails without level-shifting. |
| Temperature Range | 0°C to +70°C - qualified for commercial-grade applications including test equipment, peripheral controllers, and industrial HMI modules. |
| Package | 40P6: 40-pin, 0.600" wide plastic DIP - through-hole mountable, socket-compatible with legacy PLD footprints and manual prototyping workflows. |
Pinout & Package
ATV2500BQ-25PC uses a 40-pin plastic dual-inline package (PDIP, type 40P6) with 0.600" width and standard DIP pin spacing. Pin 1 is marked by notch or dot; pin numbering follows counterclockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK/IN | Dedicated clock input or general logic input - supports direct pin clocking of registers; required for synchronous operation. |
| 2–7, 9–13, 15–20, 22–25, 27–30, 32–39 | I/O 0–23 | Bi-directional logic buffers - even-numbered (I/O0,2,4…) and odd-numbered (I/O1,3,5…) pins support independent direction control and feedback routing. |
| 8, 21, 31, 40 | GND | Ground reference - four dedicated ground pins reduce noise coupling and improve signal integrity in high-speed PLD operation. |
| 14, 26 | VCC | +5 V supply - dual power pins ensure stable core voltage distribution across the logic array and I/O banks. |
| 33–36 | IN | General-purpose logic inputs - eight dedicated input-only pins provide additional array inputs beyond I/O feedback paths. |
Key Features
| Feature | Design Value |
|---|---|
| Fully connected logic array | All 38 array inputs (14 pins + 24 register outputs) available to every macrocell - eliminates placement constraints and maximizes logic density utilization. |
| Selectable D- or T-type flip-flops | Each of 48 registers individually configurable - enables compact JK/SR implementations and reduces product-term usage for sequential logic. |
| Buried combinatorial feedback | 24 Q2 registers bypassable to feed D/T2 directly into logic array - expands effective logic resources without consuming I/O pins. |
| Independent clock & reset per flip-flop | Dedicated product-term clock and asynchronous reset for each register - supports multi-clock domain designs and glitch-free state initialization. |
| Reprogrammable UV EPROM technology | 100% tested for programmability and erasable under 253.7 nm UV light (≥20 min @ 12,000 µW/cm²) - enables design iteration and field updates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATV2500B-25PC | Higher standby current (110 mA vs. 30 mA); same pinout, speed grade, and logic architecture. | Suitable for non-power-constrained commercial systems where thermal headroom exists. | Select ATV2500BQ-25PC when <30 mA standby ICC is required; use ATV2500B-25PC only if legacy B-version toolchain compatibility is mandatory. |
| ATV2500BL-25PC | Ultra-low standby current (2 mA); identical logic structure but optimized for minimal power - reduced speed margin (tPD = 25 ns unchanged, but tCOS = 12 ns applies). | Preferred for battery-powered or thermally restricted instrumentation where active power dominates. | Choose ATV2500BL-25PC only if system-level power budget demands sub-5 mA quiescent draw; verify timing closure under worst-case voltage/temperature. |
Compared with ATV2500B-25PC and ATV2500BL-25PC, the ATV2500BQ-25PC delivers optimal balance: 30 mA standby current enables significant power savings over the B version while retaining full-speed performance and avoiding the tighter timing margins and potential toolchain limitations of the BL variant.

FAQ
What is the maximum operating frequency supported by ATV2500BQ-25PC?
The ATV2500BQ-25PC supports up to 31 MHz external feedback clocking (FMAXS = 1/(tSIS + tCOS) = 1/(19 ns + 12 ns) ≈ 32 MHz, derated to 31 MHz per datasheet). This is achievable with proper PCB layout, 5 V ±5% supply, and commercial-temperature operation (0°C to +70°C). The device's 25 ns tPD and 12 ns tCOS define its timing envelope for synchronous logic synthesis.
Does ATV2500BQ-25PC require UV erasure before reprogramming?
Yes, ATV2500BQ-25PC uses UV-erasable EPROM technology and must be exposed to 253.7 nm ultraviolet light for ≥20 minutes at 12,000 µW/cm² intensity to fully erase the logic pattern before reprogramming. The 40P6 package has no quartz window, so erasure requires removal from PCB and placement in a certified UV eraser - unlike flash-based PLDs, it cannot be electrically erased in-system.
Is ATV2500BQ-25PC pin-compatible with other ATV2500B variants?
Yes, ATV2500BQ-25PC shares identical 40-pin PDIP (40P6) pinout and macrocell architecture with ATV2500B-25PC and ATV2500BL-25PC. All three support the same JEDEC programming files and development tools. Differences lie solely in standby current (30 mA vs. 110 mA vs. 2 mA) and internal power optimization - no PCB or socket changes are needed for substitution.
What logic synthesis tools support ATV2500BQ-25PC?
ATV2500BQ-25PC is supported by industry-standard PLD development tools including Atmel's WinCUPL, Logical Devices' ABEL, Data I/O's Universal Programmer software, and third-party tools like Synario and OrCAD PLD. Its JEDEC JED file format ensures compatibility across programmers from BP Microsystems, Xeltek, and System General.
How does the power-up reset function in ATV2500BQ-25PC?
The ATV2500BQ-25PC features an internal power-up reset that forces all 48 flip-flops to low state when VCC crosses 3.8–4.5 V (VRST), with reset duration of 600–1000 ns (tPR). This ensures deterministic initial state for state machines. Critical conditions include monotonic VCC rise and adherence to input setup times before first clock edge - no external reset circuitry is required.
