Product details
Overview
ATV2500BQ-25JC from Atmel is a high-density, UV-erasable programmable logic device (PLD) in 44-lead PLCC package, featuring 24 macrocells with 48 flip-flops, 416 product terms, 7 ns typical pin-to-pin delay, and 30 mA standby current. It supports D- or T-type flip-flop configuration per macrocell and operates across commercial temperature range (0°C to 70°C).
For engineers reviewing the ATV2500BQ-25JC datasheet, ATV2500BQ-25JC pinout, ATV2500BQ-25JC application, or ATV2500BQ-25JC equivalent, this device serves as a speed-graded, low-power upgrade path for ATV2500H/L designs requiring reprogrammability, flexible clocking, and high gate utilization in legacy digital control and interface logic.
Technical Context
The ATV2500BQ-25JC implements a fully connected universal AND-OR array with 38 array inputs (14 dedicated pins + 24 feedback signals), enabling full routability of all inputs and flip-flop outputs to every macrocell. Each macrocell contains three sum terms combinable into one 12-product-term term without speed penalty.
It provides dual flip-flops per macrocell (48 total), individually configurable for D- or T-type operation, asynchronous reset, and independent product-term or pin-based clocking. Buried combinatorial feedback via Q2 bypass allows internal signal routing without I/O pin consumption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 2500 usable gates - enables complex state machines and glue logic in single 44-lead package |
| Pin-to-Pin Delay (tPD) | 25 ns - defines maximum combinational propagation time between I/O pins |
| Standby ICC | 30 mA - significantly lower than standard ATV2500B (110 mA), reducing system quiescent power |
| Macrocells | 24 - each with two flip-flops and three sum terms, supporting registered and combinatorial outputs |
| Product Terms | 416 - fully shared across all macrocells, enabling high logic utilization (>80%) |
| Operating Voltage | 5 V ± 5% - compatible with standard TTL/CMOS logic families and legacy 5 V systems |
| Temperature Range | 0°C to 70°C - commercial-grade operation suitable for industrial control panels and instrumentation |
Pinout & Package
ATV2500BQ-25JC uses a 44-lead Plastic J-Leaded Chip Carrier (PLCC) package per JEDEC MS-018 AC. Pins 4 and 26 are not required for PLCC versions and may be left unconnected, ensuring compatibility with ATV2500H/L pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3–17, 19–25, 27–44 | I/O 0–23, IN 0–7, CLK/IN | Bi-directional buffers (even/odd grouping); 14 dedicated logic inputs; one shared clock/input pin |
| 18, 30 | VCC | +5 V supply pins - dual power connections reduce IR drop and improve noise immunity |
| 2, 29, 31 | GND | Ground terminals - three GND pins enhance return path integrity and EMI performance |
| 4, 26 | Not Connected | No internal connection - must be left floating per datasheet Note for PLCC variants |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Macrocell Configuration | Each of 24 macrocells supports independent D/T flip-flop selection, product-term or pin clocking, and registered/combinatorial feedback - enabling mixed-clock-domain logic |
| Buried Combinatorial Feedback | 24 Q2 registers can be bypassed to feed D/T2 directly into logic array - adds internal routing without consuming I/O pins |
| High Gate Utilization | Consistently achieves >80% utilization due to fully connected array and 416 shared product terms - reduces need for multiple PLDs |
| Reprogrammability | 100% tested UV-erasable EPROM technology - supports design iteration and field updates without hardware change |
| Backward Software Compatibility | Fully supports ATV2500H/L development tools and JEDEC files - enables drop-in replacement or speed upgrade |

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 | Slower tPD (15 ns vs. 25 ns), higher ICC (110 mA vs. 30 mA), no T-type flip-flops or D/T2 feedback | Limited to simpler combinatorial logic; lacks buried state machine support and flexible clocking | Select when legacy design requires exact functional subset and lower cost is prioritized over power or feature set |
| ATV2500BQL-25JC | Same speed grade and logic architecture, but LCC (44LW) ceramic leadless package instead of PLCC (44J) | Higher thermal conductivity and hermetic sealing; requires different PCB land pattern and reflow profile | Select for harsh-environment applications requiring MIL-spec reliability and improved thermal performance |
Compared with ATV2500H-15JC, ATV2500BQ-25JC delivers 3.7× lower standby power and advanced features like T-type flip-flops and buried feedback; compared with ATV2500BQL-25JC, it offers identical logic functionality but in a surface-mount PLCC package with easier hand-soldering and rework capability.

FAQ
What is the operating voltage range for ATV2500BQ-25JC?
The ATV2500BQ-25JC operates at 5 V ± 5%, meaning its valid supply range is 4.75 V to 5.25 V. This specification ensures compatibility with standard 5 V TTL and CMOS logic families. Operation outside this range may cause functional failure or damage, as confirmed by Absolute Maximum Ratings specifying -2.0 V to +7.0 V pin voltage limits only for transient conditions.
Does ATV2500BQ-25JC support in-system programming?
No, ATV2500BQ-25JC does not support in-system programming. It is a UV-erasable EPROM-based PLD requiring exposure to ultraviolet light (253.7 nm, ≥15 W·sec/cm²) for erasure and a dedicated external programmer for reprogramming. The device lacks JTAG or serial interface circuitry, and its programming voltage requirements (–2.0 V to +14.0 V) are incompatible with standard microcontroller GPIOs.
How many flip-flops does ATV2500BQ-25JC contain, and what types are supported?
The ATV2500BQ-25JC contains 48 flip-flops - two per macrocell across its 24 macrocells. Each flip-flop is individually configurable as either D-type or T-type via configuration bits, enabling efficient implementation of JK and SR functions using T-mode. This flexibility is documented in the Output Configuration tables and Functional Logic Diagram sections of the datasheet.
What is the purpose of pins 4 and 26 on ATV2500BQ-25JC?
Pins 4 and 26 on ATV2500BQ-25JC are not internally connected and must be left unconnected (NC). This is explicitly stated in the datasheet Note for ATV2500BQ and ATV2500BQL PLCC/LCC variants. Their omission ensures pinout compatibility with earlier ATV2500H/L devices, simplifying board-level upgrades without layout changes.
Is ATV2500BQ-25JC compatible with ATV2500H/L software tools?
Yes, ATV2500BQ-25JC is backward compatible with ATV2500H/L software tools and JEDEC files. It supports the full functional subset of those devices and can be programmed using ATV2500H/L design files. When used this way, ATV2500BQ-25JC acts as a direct speed and power upgrade - retaining identical logic behavior while delivering faster timing (25 ns vs. 15 ns tPD) and lower ICC (30 mA vs. 110 mA).
