Product details
Overview
ATF2500C-15JC from Atmel is a high-density, electrically-erasable programmable logic device (PLD) in a 44-lead PLCC package, delivering 15 ns maximum pin-to-pin delay at 5V, 416 product terms, and 24 flexible macrocells with dual flip-flops per macrocell. It serves as a reprogrammable logic replacement for legacy ATV2500B/BQ and ATV2500H devices in industrial control and legacy system upgrades.
For engineers reviewing the ATF2500C-15JC datasheet, ATF2500C-15JC pinout, ATF2500C-15JC application, or ATF2500C-15JC equivalent, key selection considerations include its 15 ns speed grade, PLCC-44 packaging, support for D/T-type flip-flops per macrocell, individual asynchronous reset per macrocell, and compatibility with Atmel WinCUPL software and standard V2500 JEDEC programming files.
Technical Context
The ATF2500C-15JC implements a single universal logic array with full connectivity: all 38 logic pins and all 48 flip-flop outputs feed directly into every macrocell's 416-product-term array. Each macrocell provides three sum terms combinable into up to 12 product terms without speed penalty.
It supports independent clocking per flip-flop via dedicated product terms or direct input pins, selectable D- or T-type registers per flip-flop, buried combinatorial feedback (Q2 bypass), and per-macrocell OE control. Power-up reset ensures deterministic low-state initialization across commercial temperature range (0°C to 70°C).
Key Specifications

|---|---|
| Max Pin-to-Pin Delay | 15 ns at 5V - enables synchronous logic operation up to 52 MHz with external feedback. |
| Logic Density | 416 product terms - provides high gate utilization for complex state machines and glue logic. |
| Macrocells | 24 macrocells, each with two flip-flops - delivers 48 total registers for sequential logic implementation. |
| Operating Voltage | 5V ±5% - compatible with legacy TTL/CMOS 5V systems without level translation. |
| Temperature Range | 0°C to 70°C (Commercial) - validated for stable operation in office and lab environments. |
| I/O Count | 38 logic I/O pins - supports wide bus interfacing and multi-function peripheral control. |

Pinout & Package
ATF2500C-15JC is packaged in a 44-lead Plastic J-Leaded Chip Carrier (PLCC-44), compliant with JEDEC MS-018, Variation AC. Dimensions: 17.4 mm × 17.4 mm × 4.6 mm (max height), lead pitch 1.27 mm, coplanarity ≤ 0.102 mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1–14, 17–23, 25–29, 31–43 | IN / CLK/IN / I/O | Dedicated logic inputs, shared clock/input pins, or bidirectional I/O buffers - all feed directly into global logic array. |
| 15, 16, 30, 33, 34, 44 | VCC / GND | Power supply (VCC = Pins 15, 16) and ground (GND = Pins 30, 33, 34, 44) - multiple distributed connections reduce noise and improve decoupling. |
| 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 17, 18, 19, 20, 21, 22, 23, 25, 26, 27, 28, 29, 31, 32, 35, 36, 37, 38, 39, 40, 41, 42, 43 | I/O0–23, IN0–13 | 38 total logic pins - includes even/odd I/O grouping for optimized routing; all pins support input, output, or bidirectional use with independent OE control. |
Key Features
| Feature | Design Value |
|---|---|
| Fully connected logic array | Every macrocell accesses all 38 inputs and all 48 flip-flop feedback paths - eliminates placement constraints and maximizes logic utilization. |
| Selectable D- or T-type flip-flops | Each of 48 registers configurable individually - enables compact JK/SR emulation and efficient state encoding without extra product terms. |
| Buried combinatorial feedback | Q2 output bypass option per macrocell - expands logic capacity using internal paths instead of I/O pins, preserving pin count for system signals. |
| Per-macrocell asynchronous reset | Independent AR1/AR2 product terms per flip-flop - allows selective reset of subsystems without global reset propagation delay. |
| Programmable pin-keeper circuits | Weak-latch option on all I/O pins - maintains known bus states during high-impedance periods, eliminating need for external pull-ups in legacy bus designs. |

FAQ
What is the maximum operating frequency supported by ATF2500C-15JC?
The ATF2500C-15JC supports up to 52 MHz when using external feedback paths, based on its 10 ns clock-to-output (tCOS) and 9 ns input setup time (tSIS) specifications. This frequency assumes nominal 5V supply and 25°C ambient temperature; derating applies at higher temperatures or lower supply voltages. The ATF2500C-15JC datasheet specifies FMAXS = 1/(tSIS + tCOS) = 52 MHz under these conditions.
Is ATF2500C-15JC pin-compatible with ATV2500H?
Yes, ATF2500C-15JC is pin-compatible with ATV2500H, including identical PLCC-44 pinout and optional GND connections at pins 4 and 26. The ATF2500C-15JC datasheet explicitly states it is a direct replacement for ATV2500H, supporting the same JEDEC file format and software toolchain (Atmel WinCUPL). No PCB layout changes are required for migration.
Does ATF2500C-15JC support both D-type and T-type flip-flops?
Yes, ATF2500C-15JC supports both D-type and T-type flip-flops - each of its 48 registers can be individually configured as either type via configuration bits. This flexibility enables efficient implementation of JK and SR functions using T-mode, reducing product term usage compared to fixed-architecture PLDs. Configuration is performed during JEDEC file generation.
What package type is used for ATF2500C-15JC?
ATF2500C-15JC uses a 44-lead Plastic J-Leaded Chip Carrier (PLCC-44) package, compliant with JEDEC MS-018, Variation AC. Its dimensions are 17.4 mm × 17.4 mm × 4.6 mm max height, with 1.27 mm lead pitch and 0.102 mm max coplanarity. This surface-mount package supports reflow soldering and offers mechanical robustness for industrial applications.
Can ATF2500C-15JC be programmed using standard V2500 JEDEC files?
Yes, ATF2500C-15JC supports standard V2500 JEDEC files through cross-programming modes: "ATF2500C (V2500)" mode disables User Row and pin-keeper features to match legacy V2500 fuse counts (71648 fuses), enabling seamless migration from ATV2500H. Full functionality (71816 fuses) requires recompilation targeting ATF2500C specifically in Atmel WinCUPL.
