Product details
Overview
ATF1500ABV-15JI 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 (with external feedback), and is qualified for industrial temperature range (–40°C to +85°C). It integrates legacy TTL/SSI/MSI logic in embedded control and interface glue logic applications.
For engineers reviewing the ATF1500ABV-15JI datasheet, ATF1500ABV-15JI pinout, ATF1500ABV-15JI application, or ATF1500ABV-15JI equivalent, key selection criteria include its EEPROM-based reprogrammability, pin-controlled power-down mode (5 µA standby), programmable slew rate per I/O, bus-friendly pin-keeper circuitry, and support for both product-term and global-clock register configurations.
Technical Context
The ATF1500ABV-15JI 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 - enabling any macrocell to drive any I/O without routing constraints. Its regional bus provides foldback logic to groups of 16 macrocells for efficient high-fan-in sum-term generation.
Each macrocell supports D/T/JK/SR flip-flop or transparent latch operation, with clock selectable as global CLK or individual product term, asynchronous reset/preset sourced from GCLR pin or product term, and output enable configurable per macrocell via OE1/OE2 pins or dedicated product term. The device includes a dedicated PD pin for hardware-triggered power-down mode, latching internal states and outputs while reducing ICC to ≤2 mA.
Key Specifications

Pinout & Package
ATF1500ABV-15JI is available in 44-lead PLCC (44J) and TQFP (44A) packages. This specific variant uses the 44-lead Plastic J-leaded Chip Carrier (PLCC) package, with 1.27 mm lead pitch and body size 16.59 mm × 16.59 mm.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1502ASV-15JI | 64-macrocell density, same 44J PLCC package and industrial temp rating; higher logic capacity but larger die size and 20% higher ICC1 | Suitable for designs requiring >32 macrocells or deeper state machines; not drop-in due to different JEDEC fuse map | Select when additional logic resources are needed without changing PCB footprint |
| XCR3064XL-10VQ44I | 64-macrocell Xilinx CoolRunner-II device; 3.3 V only, 10 ns tPD, 128 product terms; no PD pin or pin-keeper | Better suited for low-voltage, high-speed pure combinatorial logic; lacks hardware power-down and bus-friendly keepers | Choose for 3.3 V systems prioritizing speed and density over mixed-voltage flexibility and ultra-low standby current |
Compared with ATF1500ABV-15JI, ATF1502ASV-15JI offers double logic capacity in identical packaging but increases static power and requires full recompilation; XCR3064XL-10VQ44I delivers faster timing at 3.3 V but removes critical industrial features like pin-keeper and hardware power-down, limiting use in mixed-signal or battery-sensitive applications.

FAQ
What is the operating temperature range for the ATF1500ABV-15JI?
The ATF1500ABV-15JI 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 datasheet (Rev. 0723I–08/01). Unlike commercial variants (e.g., ATF1500ABV-15AC), the "JI" suffix explicitly denotes industrial qualification, making ATF1500ABV-15JI suitable for under-hood automotive or factory-floor control applications where ambient thermal stress exceeds commercial limits.
Does the ATF1500ABV-15JI support in-system programming?
Yes, the ATF1500ABV-15JI supports in-system programming via standard JTAG interface (IEEE 1149.1). Its EEPROM-based configuration memory allows full reprogramming while soldered on the target board, without requiring removal or UV erasure. Programming voltage is internally generated from VCC, eliminating need for external high-voltage supplies. The security fuse, once programmed, disables further readback but does not prevent subsequent reprogramming of the device.
How does the pin-keeper feature work on the ATF1500ABV-15JI?
The ATF1500ABV-15JI includes programmable data-keeper circuits on all I/O and input pins. When enabled in the design file, these circuits actively hold the last driven logic state (high or low) after the pin becomes high-impedance - preventing floating inputs that cause shoot-through current and system noise. This eliminates external pull-up/down resistors and their associated DC power loss. Keepers are disabled by default and must be explicitly activated per pin during HDL synthesis or ABEL compilation.
What is the purpose of the PD pin on the ATF1500ABV-15JI?
The PD (Power-Down) pin on the ATF1500ABV-15JI is an active-high hardware control that places the device into ultra-low-power standby mode (<2 mA ICC) when asserted. In this state, all internal logic states and output levels are latched and held, and input transitions are ignored until PD returns low. The PD function must be enabled in the design source file; once enabled, the PD pin cannot serve as a general-purpose I/O but retains full macrocell functionality for buried logic generation.
Can the ATF1500ABV-15JI operate reliably at 2.7 V supply?
Yes, the ATF1500ABV-15JI is fully specified to operate down to 2.7 V across its entire industrial temperature range. DC characteristics (e.g., VOL, VOH, IIH, IIL) and AC timing parameters (including tPD = 12 ns max and fMAXS = 52.6 MHz) are guaranteed at VCC = 2.7 V, as documented in the "DC and AC Operating Conditions" and "AC Characteristics" tables. This makes ATF1500ABV-15JI compatible with brown-out conditions and battery-powered systems where supply voltage may dip near minimum thresholds.
