Product details
Overview
ATF1500ABV-15JC from Atmel is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 32 macrocells, 32 I/O pins, and a maximum pin-to-pin delay of 12 ns. It operates from 2.7V to 5.5V, supports registered logic up to 52.6 MHz (fMAXS), and features programmable slew rate, pin-keeper inputs, and pin-controlled power-down mode. It is used in industrial control logic consolidation and legacy TTL replacement.
For engineers reviewing the ATF1500ABV-15JC datasheet, ATF1500ABV-15JC pinout, ATF1500ABV-15JC application, or ATF1500ABV-15JC equivalent, key selection criteria include its 44-pin PLCC package, industrial temperature range (–40°C to +85°C), 10,000 program/erase cycles, 20-year data retention, and support for global/regional bus architecture enabling flexible logic placement without pinout changes.
Technical Context
The ATF1500ABV-15JC implements a fully connected global input and feedback logic array, allowing any of its 32 macrocells to drive any I/O pin-eliminating routing-induced pinout revisions. Its architecture includes four 40-term cascade chains and regional buses feeding 16-macrocell groups, enabling high-fan-in sum-of-products with minimal delay penalty.
Each macrocell supports D/T/latch-configurable flip-flops, individual output enable (OE1/OE2), global register control (GCLR, CLK), and buried feedback to the global bus. The device integrates pin-keeper circuits on all I/Os to prevent floating states and reduce system noise, plus optional power-down mode activated via the PD pin (typical 2 mA ICC2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 32 macrocells - provides sufficient resources to replace multiple SSI/MSI TTL devices or classic PLDs in glue logic applications. |
| Max Pin-to-pin Delay | 12 ns - enables reliable operation in systems requiring sub-100 ns timing-critical paths. |
| Max Registered Frequency | 52.6 MHz (fMAXS) - supports synchronous logic at industrial bus speeds including ISA, parallel port, and custom control interfaces. |
| Supply Voltage Range | 2.7V to 5.5V - allows direct interfacing with both 3.3V and 5V logic families without level-shifting. |
| Program/Erase Cycles | 10,000 - ensures field-upgradable firmware logic over extended product lifecycles in embedded systems. |
| Data Retention | 20 years - guarantees nonvolatile configuration integrity across industrial equipment service intervals. |
| ESD Protection | 2000V HBM - meets IEC 61000-4-2 Level 2 requirements for robustness in factory automation environments. |
| Latchup Immunity | 200 mA - prevents destructive latchup during transient overvoltage events on I/O lines. |
Pinout & Package
ATF1500ABV-15JC is packaged in a 44-lead Plastic J-leaded Chip Carrier (PLCC), suitable for through-hole or surface-mount assembly with standard reflow profiles. The PLCC package provides mechanical stability and thermal performance appropriate for industrial ambient conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Global clock input | Primary synchronous edge-trigger source for all macrocell registers; rising-edge sensitive. |
| GCLR | Asynchronous global clear | Active-low reset signal shared across all macrocells; may be OR'd with product-term reset for selective clearing. |
| OE1, OE2 | Output enable controls | Two dedicated active-low output enables; each assignable per macrocell for fine-grained I/O direction control. |
| PD | Power-down control | Active-high pin that latches internal state and reduces ICC2 to 2 mA when asserted; disables all input transitions except PD itself. |
| I/O (pins 1–32, 34–43) | Bi-directional logic interface | Configurable as input, output, or bidirectional; each supports programmable slew rate and pin-keeper functionality. |
| VCC (pins 9, 16, 28, 44) | Power supply | Four distributed VCC pins minimize IR drop and improve noise immunity across the logic array. |
| GND (pins 4, 22, 33) | Ground reference | Three GND pins provide low-inductance return paths for switching currents and reduce ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Fully connected global bus | All 32 I/Os and 32 macrocell feedback signals feed a 68-bit global bus - eliminates routing congestion and enables logic reallocation without PCB revision. |
| Programmable pin-keeper | On-chip keeper circuit holds unused I/Os at last driven logic level - removes need for external pull-ups and cuts standby current in unconnected states. |
| Macrocell flexibility | Each macrocell supports D/T/latch flip-flops, XOR-based arithmetic, buried feedback, and combinatorial/registered output selection - accommodates diverse logic styles in one device. |
| Individual slew rate control | Per-I/O configurable slow/fast edge rates - reduces EMI on non-critical outputs while preserving timing margins on high-speed paths. |
| Security fuse | One-time programmable fuse blocks JEDEC file readback and preload access - protects proprietary logic design from reverse engineering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1502ASV-15JC | 64-macrocell variant with identical 44J PLCC package, same voltage/temperature specs, and enhanced cascade logic (up to 80 terms). | Supports larger logic functions without increasing board area; requires updated JEDEC programming but same PCB layout. | Select when design grows beyond 32 macrocells but must retain mechanical and thermal compatibility. |
| XCR3064XL-10VQ44C | Xilinx CoolRunner-II CPLD: 64 macrocells, 10 ns tPD, 3.3V-only supply, different pinout (VQFP), no PD pin or pin-keeper. | Requires PCB redesign and voltage translation for 5V systems; lacks industrial temp grade in this speed bin. | Consider only for new 3.3V designs needing higher density and lower static power; not drop-in compatible. |
Compared with ATF1500ABV-15JC, ATF1502ASV-15JC offers scalable logic capacity within identical packaging and thermal envelope, while XCR3064XL-10VQ44C demands board-level changes and sacrifices industrial temperature support - making ATF1500ABV-15JC optimal for cost-sensitive, footprint-constrained industrial retrofits.

FAQ
What is the operating temperature range for ATF1500ABV-15JC?
The ATF1500ABV-15JC is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the Ordering Information table and DC Operating Conditions section of the official Atmel datasheet (Rev. 0723I–08/01). The "J" suffix explicitly denotes the PLCC package with industrial-grade qualification, distinguishing it from commercial-grade variants like ATF1500ABV-15AC.
Does ATF1500ABV-15JC support in-system programming?
Yes, ATF1500ABV-15JC supports in-system programming via IEEE 1149.1 JTAG interface. Its advanced EEPROM technology enables full reprogramming without removal from the PCB. The device is 100% tested and guarantees 10,000 program/erase cycles with 20-year data retention - making it suitable for field updates and manufacturing reconfiguration.
What is the function of the PD pin on ATF1500ABV-15JC?
The PD (Power-Down) pin on ATF1500ABV-15JC is an active-high control input that places the device into a low-power standby mode drawing ≤2 mA typical current. When asserted, all internal logic states and output levels are latched, and input transitions (except PD itself) are ignored. The PD pin functionality must be enabled in the design source file; once enabled, it cannot serve as a general-purpose I/O.
Can ATF1500ABV-15JC replace older PAL/GAL devices in existing designs?
Yes, ATF1500ABV-15JC is widely used to replace obsolete PAL and GAL devices such as GAL16V8 or PALCE22V10. Its 44-pin PLCC footprint matches many legacy packages, and its 32 macrocells with fully connected architecture allow direct mapping of combinatorial and registered logic functions. JEDEC file compatibility simplifies migration using standard third-party design tools.
Is the ATF1500ABV-15JC pinout compatible with other ATF1500ABV speed grades?
Yes, all ATF1500ABV variants-including ATF1500ABV-12JC, ATF1500ABV-15JC, and ATF1500ABV-15JI-share identical 44-pin PLCC (44J) pinouts and electrical characteristics. Speed grade differences (e.g., 12 ns vs. 15 ns tPD) reflect internal timing parameters only; no PCB layout change is required when upgrading or substituting within the same package type.
