Product details
Overview
ATV2500B-15JC from Atmel is a high-density, UV-erasable programmable logic device (PLD) in a 44-lead PLCC package, delivering 7 ns pin-to-pin delay, 416 product terms in a fully connected logic array, and 48 flip-flops (two per macrocell). It supports D- or T-type register configuration, individual product-term clocking, and operates across commercial temperature range (0°C to 70°C) with 5 V ±5% supply.
For engineers reviewing the ATV2500B-15JC datasheet, ATV2500B-15JC pinout, ATV2500B-15JC application, or ATV2500B-15JC equivalent, this device serves as a speed-graded replacement for ATV2500H/L in legacy PLD designs requiring registered logic, combinatorial flexibility, and reprogrammability - especially where pin-compatible migration from older 44-lead PLDs is needed.
Technical Context
The ATV2500B-15JC implements a single universal AND-OR logic array with all 38 logic pins and 48 flip-flop outputs feeding into 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 features dual independent registers per macrocell (D/T-type selectable), dedicated asynchronous reset and clock product terms per flip-flop, individual output enable product terms, and eight synchronous preset terms distributed in a 2/4 pattern across macrocell groups. Power supply current in standby is 110 mA (typical) at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 15 ns - defines maximum combinational path timing for logic synthesis and critical path verification |
| Clock-to-Output (tCOS) | 10 ns - determines minimum clock-to-data valid window for synchronous output timing closure |
| Max Frequency (fMAXS) | 52 MHz - sets upper limit for external feedback-based state machine clocking |
| Logic Density | 2500 usable gates - enables complex glue logic integration in space-constrained PCBs |
| Product Terms | 416 total - provides full interconnectivity across all macrocells for high gate utilization (>80%) |
| Flip-flops | 48 (2 per macrocell) - supports dual-register per I/O for pipeline stages, counters, and state retention |
| Supply Voltage | 5 V ±5% - requires stable 5 V rail; not compatible with 3.3 V or mixed-voltage systems |
Pinout & Package
ATV2500B-15JC uses a 44-lead Plastic J-Leaded Chip Carrier (PLCC) package, compliant with JEDEC MS-018 AC standard. Pin 1 is marked by a corner notch; pins are numbered counterclockwise starting from the notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–7, 9–10, 12–14, 16–17, 19–20, 22–23, 25–27, 29–30, 32–33, 35–36, 38–39 | I/O 0–23 (even/odd grouped) | Bi-directional logic buffers with individually configurable registered/combinatorial mode and output enable control |
| 8, 11, 15, 18, 21, 24, 28, 31, 34, 37, 40–43 | IN 0–13, CLK/IN | Dedicated logic inputs; CLK/IN serves as primary clock source or secondary input with direct pin clocking capability |
| 4, 26 | No Connect (NC) | Not required for PLCC versions - omitted from routing; no PCB trace or pull-up/down needed |
| 3, 22, 31, 44 | GND | Four ground terminals - reduce ground bounce and improve noise immunity in high-speed switching |
| 11, 12 | VCC | +5 V supply pins - must be decoupled locally with 0.1 µF ceramic capacitors near each VCC pin |
Key Features
| Feature | Design Value |
|---|---|
| Fully connected logic array | Every macrocell receives all 38 input and 48 feedback signals - eliminates manual logic placement constraints during design |
| Selectable D- or T-type flip-flops | Each of 48 registers independently configured - enables JK/SR emulation and efficient state encoding |
| Buried combinatorial feedback | 24 Q2 registers bypassable to feed D/T2 directly into logic array - adds internal logic depth without consuming I/O pins |
| Individual product-term clocking | Each flip-flop has dedicated clock product term - allows multiple independent clock domains within one device |
| Preload and observability support | Asynchronous register loading via odd I/O pins and buried register readback on SMP pin 2 - simplifies boundary-scan test and debug |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATV2500H-15JC | Lacks T-type flip-flops and D/T2 feedback; 10 ns tPD; same 44J package and JEDEC file format | Supports only D-type registers and pin-clocking - insufficient for JK-emulation or buried feedback designs | Select when migrating legacy designs that do not require T-type functionality or combinatorial feedback paths |
| ATV2500BQ-15JC | Same logic architecture but 30 mA standby ICC (vs. 110 mA); identical pinout and timing specs | Preferred for battery-powered or thermally constrained systems where power efficiency is prioritized over raw speed margin | Choose for commercial-temp applications needing lower static power without sacrificing 15 ns performance or macrocell flexibility |

FAQ
What is the operating temperature range for ATV2500B-15JC?
The ATV2500B-15JC is rated for commercial operation from 0°C to 70°C ambient temperature. It uses a 5 V ±5% supply and is specified for this range in all DC and AC parameters, including tPD = 15 ns and fMAXS = 52 MHz. Industrial or military variants (e.g., ATV2500B-15JI) exist but require different ordering codes.
Does ATV2500B-15JC support T-type flip-flops?
Yes, ATV2500B-15JC supports both D- and T-type flip-flops - each of its 48 registers can be individually configured. This enables efficient implementation of JK and SR flip-flops via T-type logic, a feature absent in the earlier ATV2500H/L family and confirmed in the functional logic diagram and output configuration tables.
Is ATV2500B-15JC pin-compatible with ATV2500H-15JC?
Yes, ATV2500B-15JC shares the identical 44-lead PLCC (44J) package and pinout with ATV2500H-15JC, including NC assignments at pins 4 and 26. However, ATV2500B-15JC adds T-type register support and buried feedback - features not used in ATV2500H-15JC JEDEC files, so full functional compatibility requires updated programming.
What programming voltage does ATV2500B-15JC require?
ATV2500B-15JC requires a programming voltage of −2.0 V to +14.0 V on input pins relative to ground, per Absolute Maximum Ratings. Standard UV-EPROM programmers apply +12.5 V during programming pulses; erasure requires 253.7 nm UV light for ≥20 minutes at 12,000 µW/cm² intensity through the PLCC window.
Can ATV2500B-15JC be used in place of ATV2500BQ-15JC?
Yes, ATV2500B-15JC and ATV2500BQ-15JC share identical timing (15 ns tPD), pinout, and logic architecture, but differ in standby current: ATV2500B-15JC draws 110 mA vs. 30 mA for ATV2500BQ-15JC. Substitution is electrically valid if system power budget permits the higher ICC - no PCB or firmware changes needed.
