概述

Description

ATF1502ASV-15AU44 is an antifuse-based small programmable logic device (PLD) from Atmel (now Microchip), in the ATF15xx family. It provides a compact set of programmable logic resources and I/O pins in a 44-pin AU44 package. Used for glue logic, simple state machines, decoders, and other basic digital circuits, it is programmed once (antifuse) and is non-volatile after programming. The -15 denotes the speed grade, while AU44 indicates the 44-pin package; ASV denotes a specific package/variant (RoHS/temperature option). For exact capabilities (I/O count, logic density, voltage and timing specs) and programming details, refer to the official datasheet and package drawings.

Features

Here are concise, general features of the ATF1502ASV-15AU44 (CPLD from Atmel/Microchip):
- 44-pin AU44 package
- Macrocell-based programmable logic (CPLD) with configurable interconnect
- In-system programmable (no external PROM required); non-volatile configuration stored on-chip
- 5V tolerant I/O with TTL/CMOS-compatible levels
- Flexible I/O options, including registered outputs (optional)
- Small footprint and low power for glue logic, small interfaces, and simple state machines
- Simple, fast reconfiguration suitable for interfacing and control logic
Note: For exact specifications (gate count, timing, I/O counts per package, etc.), please refer to the official datasheet.

Package

It uses a 44-pin Thin Quad Flat Pack (TQFP) package.

Pinout

- Pin count: 44 pins (AU44 package)
- Function: Antifuse-based field-programmable gate array (FPGA)/programmable logic device from Actel (ATF1502ASV). It provides configurable logic blocks and I/O for implementing user digital logic.

Manufacturer

Manufacturer: Actel Corporation (today part of Microchip Technology via Microsemi).
What kind of company: An American semiconductor company that designs and sells FPGAs, especially antifuse-based non-volatile FPGAs.

Application

- Glue logic and peripheral interfaces for microprocessors/microcontrollers
- Control logic, state machines, timing circuits
- Small DSP/data-path blocks
- Custom interface bridges (SPI, I2C/serial, parallel)
- Telecom, automotive, and industrial automation electronics
- Prototyping and low-volume products requiring fixed, nonvolatile programmable logic
- Fixed, nonvolatile antifuse-based, one-time-programmable logic

Equivalent

Direct one-to-one equivalents for ATF1502ASV-15AU44 do not exist; it’s a legacy Atmel CPLD. For replacement, select a modern CPLD/FPGA with similar capacity and I/O in a 44-pin package. Possible families: Lattice ispMACH/MachXO2 or Xilinx CoolRunner-II. Use distributor cross-reference to match gates, speed, voltage, and pinout (AU44).
