Product details
Overview
ATV2500BL-20JC from Atmel is a high-density, UV-erasable programmable logic device (PLD) with 24 macrocells, 48 flip-flops, and a fully connected 416-product-term logic array. It delivers 11 ns clock-to-output delay (tCOS), 2 mA standby current (ICC), and operates at 40 MHz maximum external feedback frequency in commercial temperature range (0°C to 70°C). It is used in legacy industrial control logic replacement and reconfigurable digital state machine implementations.
For engineers reviewing the ATV2500BL-20JC datasheet, ATV2500BL-20JC pinout, ATV2500BL-20JC application, or ATV2500BL-20JC equivalent, this page provides verified functional identity, confirmed PLCC-44 package mapping, validated macrocell-level timing and power specs, and two rigorously cross-checked alternative parts for logic density and low-power PLD migration paths.
Technical Context
The ATV2500BL-20JC implements a single universal AND-OR logic array with all 38 logic pins and all 48 flip-flop outputs available to every macrocell. Each of its 24 macrocells contains 17 AND gates with 172 inputs, three sum terms combinable into up to 12 product terms per sum term without speed penalty.
It supports individually configurable D- or T-type flip-flops per macrocell, product-term or direct input pin clocking, registered or combinatorial internal feedback, and asynchronous reset with 15 ns recovery time. Its 2 mA ICC standby current reflects optimized UV EPROM process power gating for battery-backed or low-quiescent systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-density, low-power PLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATV2500BQ-20JC | Same 44J PLCC package and 11 ns tCOS, but 30 mA ICC standby - lacks low-power EPROM optimization | Suitable for non-battery applications where logic density and speed match ATV2500BL-20JC but power budget is relaxed | Select when system-level power budget permits higher quiescent draw and UV erasure cycle count is less critical |
| ATV2500B-20JC | Same 44J package and 11 ns tCOS, but 110 mA ICC standby - standard-performance variant without low-power process | Used in high-speed industrial motion control where thermal headroom exists and maximum clock rate stability is prioritized over power | Choose only when 2 mA standby is not required and legacy design compatibility with ATV2500B family toolchain is mandatory |
Compared with ATV2500BQ-20JC and ATV2500B-20JC, the ATV2500BL-20JC uniquely delivers identical 11 ns timing and 44J footprint while reducing standby current by 93% and 98%, respectively - making it the sole choice for power-constrained reprogrammable logic in commercial-temperature environments.

Manufacturer
Atmel Corporation was a U.S.-based semiconductor company specializing in microcontrollers, nonvolatile memory, and programmable logic devices before its acquisition by Microchip Technology in 2016. Its PLD portfolio emphasized reprogrammability, high gate utilization, and industrial reliability.
The ATV2500B(Q)(L) family was designed for high-density, field-upgradable logic replacement in commercial and industrial systems - targeting applications where UV-erasable reprogrammability, pin-compatible migration from older PLDs, and deterministic timing were critical.
FAQ
What is the standby current specification for ATV2500BL-20JC?
The ATV2500BL-20JC has a typical standby current (ICC) of 2 mA at VCC = 5 V and 0°C to 70°C ambient temperature, with a maximum of 5 mA under worst-case conditions. This ultra-low ICC is achieved through Atmel's optimized UV EPROM process and distinguishes the "L" suffix variant from standard ATV2500B (110 mA) and low-power ATV2500BQ (30 mA) versions. The 2 mA value is measured with all inputs at GND or VCC and outputs open.
Does ATV2500BL-20JC support both D-type and T-type flip-flops?
Yes, the ATV2500BL-20JC supports individually configurable D-type or T-type flip-flops in each of its 24 macrocells. This is implemented via configuration bits S4/S5 (Register 1 Type) and S7 (Register 2 Type) in the device's fuse map. Selecting T-type enables efficient JK or SR flip-flop synthesis, reducing product-term usage by up to 33% compared to D-only implementations - a capability confirmed in the Functional Logic Diagram Description on page 4 of the datasheet.
What package type does ATV2500BL-20JC use, and is it RoHS-compliant?
ATV2500BL-20JC uses a 44-lead Plastic J-Leaded Chip Carrier (PLCC), designated as package code "44J" per Atmel's Ordering Information table. It is a leaded, non-RoHS-compliant package manufactured prior to 2006, consistent with the 2000-dated datasheet revision. No lead-free or RoHS-compliant variant of ATV2500BL-20JC was released; modern replacements require migration to newer PLD families.
Can ATV2500BL-20JC be programmed using standard ATV2500H/L software tools?
Yes, the ATV2500BL-20JC is backward compatible with ATV2500H/L programming software and JEDEC files. When configured to use only the ATV2500H/L functional subset - i.e., disabling T-type flip-flops, pin clocking, and D/T2 feedback - the ATV2500BL-20JC operates as a direct speed upgrade with identical JEDEC file support. This compatibility is explicitly stated in the Programming Software Support section on page 12 of the datasheet.
What is the power-up reset behavior of ATV2500BL-20JC?
The ATV2500BL-20JC performs an automatic power-up reset: when VCC crosses VRST (3.8–4.5 V), all 48 flip-flops reset to the low state within tPR = 600–1000 ns. This behavior is process-guaranteed and requires monotonic VCC rise, adherence to input setup times before clock activation, and clock signal stability during tPR. The reset ensures deterministic initial state in control logic without external reset circuitry.
