Product details
Overview
ATF1500ABV-15AI from Microchip Technology (formerly Atmel) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 32 macrocells, 32 I/O pins, and 4 dedicated global control inputs. It operates from 2.7V to 5.5V, delivers 12 ns maximum pin-to-pin delay, supports registered logic up to 52.6 MHz (fMAXS), and targets industrial control logic consolidation, legacy TTL replacement, and FPGA configuration glue logic.
For engineers reviewing the ATF1500ABV-15AI datasheet, ATF1500ABV-15AI pinout, ATF1500ABV-15AI application, or ATF1500ABV-15AI equivalent, key selection criteria include industrial temperature range (-40°C to +85°C), TQFP/PLCC package compatibility, programmable slew rate per I/O, pin-controlled power-down mode (5 µA standby), and EEPROM-based reprogrammability with 10,000 erase cycles.
Technical Context
The ATF1500ABV-15AI implements a fully connected global input and feedback architecture: all 32 macrocells receive signals from a 68-bit global bus containing all I/Os, dedicated inputs, and buried feedbacks. This eliminates routing bottlenecks and enables design changes without pinout revision.
Each macrocell integrates five product terms, OR/XOR/cascade logic, a D/T/Latch-configurable flip-flop with global or product-term clock, asynchronous reset/preset, and output enable selectable from OE1/OE2 pins or individual product terms. Foldback logic feeds regional buses for efficient high-fan-in sum-term generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Range | 2.7V–5.5V operation enables direct interface with 3.3V and 5V logic families without level shifters. |
| Max Pin-to-Pin Delay | 12 ns ensures timing closure in high-speed control paths such as address decoding or state machine transitions. |
| Max Registered Speed | 52.6 MHz (fMAXS) supports synchronous logic at system clocks up to 19 ns period in industrial environments. |
| I/O Count | 32 bi-directional I/Os plus 4 dedicated inputs (CLK, GCLR, OE1, OE2) provide flexible signal routing for medium-complexity glue logic. |
| Power-Down Current | Typical 5 µA standby current allows ultra-low-power operation during system sleep modes. |
| EEPROM Endurance | 10,000 program/erase cycles and 20-year data retention support field firmware updates and long-life deployments. |
| ESD Protection | 2000V HBM ESD rating ensures robustness against handling and board-level electrostatic discharge events. |
Pinout & Package
ATF1500ABV-15AI is available in two industrial-grade packages: 44-lead TQFP (44A) and 44-lead PLCC (44J). Both packages feature identical pin functions and electrical characteristics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Global clock input | Primary synchronous edge-trigger source for all macrocells; rising-edge sensitive. |
| GCLR | Asynchronous global clear | Active-low reset that forces all registers to low state; may be OR'd with product-term reset. |
| OE1, OE2 | Output enable controls | Active-low enables/disables groups of I/O buffers; each macrocell selects OE1, OE2, or product-term OE. |
| PD | Power-down control | Active-high entry into 5 µA standby mode; latches internal states and holds outputs. |
| VCC, GND | Power supply terminals | Four VCC and three GND pins distributed across package for low-noise, stable core voltage delivery. |
| I/O[0:31] | Bi-directional logic buffers | Configurable as input, output, or bidirectional; each supports programmable slew rate and pin-keeper logic. |
Key Features
| Feature | Design Value |
|---|---|
| Fully connected global bus | 68-bit global bus (all I/Os + feedbacks + complements) ensures any macrocell accesses any signal-no routing congestion or pinout lock-in. |
| Programmable slew rate per I/O | Per-pin edge-rate control reduces simultaneous switching noise (SSN) on critical data buses while maintaining speed on timing-critical paths. |
| Pin-keeper circuitry | Configurable data-hold on floating inputs/I/Os eliminates need for external pull-ups and prevents intermediate-voltage-induced shoot-through current. |
| Dedicated global control inputs | CLK, GCLR, OE1, OE2 are hardwired to all macrocells-enabling consistent clock/reset distribution without consuming logic resources. |
| Security fuse | One-time programmable fuse blocks JEDEC file readback and preload access, protecting proprietary logic configurations 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-15AI | 64-macrocell variant with identical pinout, same 12 ns delay, but higher density and expanded I/O count (68 I/O). | Required when logic resource demand exceeds 32 macrocells; no change to PCB layout needed. | Select when future design scalability or increased combinatorial depth is anticipated without altering physical footprint. |
| XCR3064XL-10VQ44I | Xilinx CoolRunner-II CPLD: 64 macrocells, 5V-tolerant I/O, 10 ns tPD, but requires different programming protocol and toolchain. | Suitable for new designs prioritizing lower static current (<10 µA) and longer EEPROM retention (>100 years), but not drop-in compatible. | Choose for greenfield projects where Xilinx toolchain integration and extended data retention outweigh migration effort. |
Compared with ATF1500ABV-15AI, ATF1502ASV-15AI offers immediate density headroom within identical packaging and timing, while XCR3064XL-10VQ44I provides superior static power and longevity at the cost of toolchain and programming infrastructure changes.

FAQ
What is the operating temperature range for the ATF1500ABV-15AI?
The ATF1500ABV-15AI is rated for industrial operation from -40°C to +85°C. This specification is validated per the device's DC and AC operating conditions table and applies to both TQFP (44A) and PLCC (44J) package variants. The "I" suffix explicitly denotes industrial temperature grade, distinguishing it from commercial-grade variants like ATF1500ABV-15AC.
Does the ATF1500ABV-15AI support in-system programming?
Yes, the ATF1500ABV-15AI supports in-system programming via JTAG (IEEE 1149.1) using standard boundary-scan tools. Its advanced EEPROM technology allows full reprogramming without removal from the PCB. Programming voltage requirements (−2.0V to +14.0V on input pins during programming) and timing are defined in the official Microchip datasheet revision 0723I–08/01.
How does the pin-keeper feature work on the ATF1500ABV-15AI?
The ATF1500ABV-15AI implements programmable pin-keeper circuits on all I/O and input pins. When enabled in the design file, these circuits retain the last driven logic state (high or low) after the pin becomes floating-preventing undefined voltage levels, reducing system noise, and eliminating external pull-up resistors. Pin-keepers are disabled by default and configured during JEDEC file generation.
Can the PD pin on the ATF1500ABV-15AI be used as a general-purpose I/O?
No-the PD pin cannot function as a general-purpose I/O when power-down mode is enabled. Once the power-down feature is selected in the design source file, the PD pin becomes a dedicated active-high control input. In this mode, it overrides all logic functionality on that pin; however, the associated macrocell's buried feedback and foldback logic resources remain usable for internal signal generation.
What is the maximum clock frequency supported by the ATF1500ABV-15AI in registered mode?
The ATF1500ABV-15AI supports a maximum registered operating frequency of 52.6 MHz (fMAXS) when using the global CLK pin and external feedback path, as specified in the AC characteristics table for industrial temperature range. This value assumes VCC = 3.0 V; derating applies at 2.7 V or elevated temperatures per the datasheet's 2.7-volt adder values.
