Product details
Overview
ATF1500ABV-12JC from Atmel is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 32 macrocells, 32 I/O pins, and 4 dedicated input/control pins. It operates from 2.7V to 5.5V, delivers 12 ns maximum pin-to-pin delay, supports registered logic up to 90.9 MHz, and integrates TTL/SSI/MSI logic replacement in industrial control and legacy interface bridging applications.
For engineers reviewing the ATF1500ABV-12JC datasheet, ATF1500ABV-12JC pinout, ATF1500ABV-12JC application, or ATF1500ABV-12JC equivalent, key selection criteria include its 44-pin TQFP/PLCC packaging, programmable slew rate per I/O, pin-controlled power-down mode (5 µA standby), and EEPROM-based reprogrammability with 10,000 erase/write cycles and 20-year data retention.
Technical Context
The ATF1500ABV-12JC implements a fully connected global input and feedback architecture, enabling any macrocell to drive any I/O pin without routing constraints. Its 32 macrocells each feature five product terms, configurable D/T/latch flip-flops, and dual-mode clocking (global CLK or product-term clock).
It supports cascaded logic chains (four chains, up to 40-product-term fan-in), regional bus folding (16-macrocell groups), and buried feedback to the global bus - all contributing to deterministic timing and design flexibility for state machines and glue logic consolidation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 32 macrocells with 5 product terms each, supporting up to 36 inputs and full interconnectivity. |
| Max Pin-to-pin Delay | 12 ns - enables synchronous logic operation at ≤62.5 MHz with external feedback. |
| Operating Voltage | 2.7V–5.5V - compatible with 3.3V and 5V systems without level-shifting. |
| Standby Current | 5 µA typical - achieved via pin-controlled power-down mode for ultra-low-power hold states. |
| EEPROM Endurance | 10,000 program/erase cycles - supports field firmware updates and iterative design validation. |
| Data Retention | 20 years - ensures long-term configuration integrity in unpowered storage or infrequently powered systems. |
| ESD Protection | 2000V HBM - provides robust handling during board assembly and system integration. |
Pinout & Package
ATF1500ABV-12JC is available in a 44-lead TQFP (44A) package, measuring 10.10 mm × 10.10 mm × 1.0 mm, with gull-wing leads and pin 1 marked by a corner chamfer. The device uses a symmetric quad layout with VCC, GND, and I/O distributed across all four sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Global clock input | Drives all macrocell flip-flops synchronously; supports rising-edge-triggered operation. |
| GCLR | Active-low global reset | Asynchronously resets all registers to low on power-up or system initialization. |
| OE1, OE2 | Active-low output enable | Individually controls tri-state behavior of I/O banks; configurable per macrocell. |
| PD | Power-down control (active high) | Enters sub-10 µA standby when asserted; latches outputs and internal state. |
| I/O (pins 1–32, 34–43) | Bi-directional logic buffer | Programmable as input, output, or bidirectional; includes pin-keeper circuitry to prevent floating. |
| VCC (pins 9, 16, 28, 37) | Power supply | Four distributed VCC pins reduce IR drop and improve noise immunity in high-speed switching. |
| GND (pins 4, 21, 27, 44) | Ground reference | Four dedicated ground pins provide low-inductance return paths for I/O and core logic. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Slew Rate | Per-I/O edge-rate control reduces EMI and crosstalk on non-critical signals while preserving speed on timing-critical paths. |
| Pin-keeper Circuitry | Eliminates need for external pull-ups on unused inputs/I/Os, cutting BOM cost and static power consumption. |
| Flexible Flip-flop Modes | D/T/JK/SR/latch configuration per macrocell enables direct mapping of state machine transitions and arithmetic functions. |
| Security Fuse | Prevents unauthorized readback of JEDEC fuse pattern, protecting proprietary logic designs from cloning. |
| Power-up Reset | Guarantees known low-state initialization of all registers at VCC ≥2.2 V, simplifying boot-time sequencing. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1502ASV-15JU | Higher density (64 macrocells), 15 ns speed grade, PLCC-84 package - not pin-compatible. | Supports larger logic functions but requires PCB redesign and higher power. | Select when logic resource demand exceeds 32 macrocells and board space permits larger footprint. |
| XCR3064XL-10VQ44C | Xilinx CoolRunner-II CPLD; 64 macrocells, 10 ns, 3.3V-only, VQFP-44 package - different architecture and toolchain. | Lacks EEPROM nonvolatility; requires external configuration PROM; no pin-keeper or PD mode. | Choose for lower static power in 3.3V-only systems where reprogramming via JTAG is acceptable and security fuse not required. |
Compared with ATF1500ABV-12JC, ATF1502ASV-15JU offers greater logic capacity but demands layout changes and higher supply current, while XCR3064XL-10VQ44C trades nonvolatility and integrated power management for lower active power and mature synthesis tool support.

FAQ
What is the operating temperature range for ATF1500ABV-12JC?
The ATF1500ABV-12JC is rated for the industrial temperature range of –40°C to +85°C. This specification is confirmed in the Ordering Information table, where "J" suffix denotes industrial grade, and is validated by DC/AC operating condition tables showing performance over that full range. The device maintains 12 ns pin-to-pin delay and functional integrity across this span.
Does ATF1500ABV-12JC support in-system programming?
Yes, ATF1500ABV-12JC supports in-system programming via IEEE 1149.1 JTAG interface. Its EEPROM technology allows full reconfiguration without removal from the PCB. Programming voltage requirements (–2.0V to +14.0V on input pins during programming) and JTAG instruction set compliance are documented in the official Atmel datasheet Rev. 0723I–08/01.
What package type does ATF1500ABV-12JC use?
ATF1500ABV-12JC uses a 44-lead Plastic J-leaded Chip Carrier (PLCC) package, designated as "44J" in Atmel's ordering nomenclature. This surface-mount package features J-shaped leads, a 16.5 mm × 16.5 mm body, and is RoHS-compliant per Atmel's packaging documentation.
Can ATF1500ABV-12JC operate at 3.3V?
Yes, ATF1500ABV-12JC operates across 2.7V to 5.5V, fully supporting 3.3V nominal supply. DC characteristics tables confirm VIH/VIL thresholds, VOL/VOH levels, and ICC values at VCC = 3.0V, and AC timing parameters (e.g., tPD = 12 ns, fMAXS = 62.5 MHz) are specified at 3.0V - making it suitable for mixed-voltage 3.3V/5V system interfaces.
Is there a pin-compatible upgrade path from ATF1500ABV-12JC?
No pin-compatible upgrade exists within the ATF1500ABV family. Higher-density variants like ATF1502ASV require different packages (e.g., PLCC-84). While ATF1500ABV-15JC shares the same 44J package, it has slower timing (15 ns vs. 12 ns) and is not a performance upgrade. Migration requires logic redesign and PCB layout revision.
