ATF1504ASV-15AU100

ATF1504ASV-15AU100 is a small flash-based CPLD (complex programmable logic device) from Atmel (now Microchip) in the ATF1500 family. It provides a limited set of configurable logic blocks (macrocells) and I/O to implement glue logic, simple state machines, decoders, and related tasks in a compact package.
Key points:
- Non-volatile configuration stored in on-chip flash; retains logic without power.
- Designed for small, low‑to‑moderate complexity logic needs with straightforward programming flow.
- The “-15” denotes a 15 ns speed grade; “AU100” indicates the package/variant code.
- Typically programmed with Atmel/Microchip programming tools; used in systems that benefit from reprogrammable logic without external memory.
When to use: for simple control/logical tasks in embedded systems, prototyping, or legacy designs needing a compact, reconfigurable logic solution. For exact resources (macrocells, I/O count, voltage ranges, pinout), consult the official datasheet.

Pin count: 20 pins (SOP-20/DIP-20 style package).
Function: Atmel ATF1504ASV-15AU100 is a 4-macrocell programmable logic device (PAL/PLD) used to implement simple combinational logic functions.

Manufacturer: Atmel Corporation (now part of Microchip Technology).
What kind of company: A semiconductor company that designs and manufactures integrated circuits, including microcontrollers, memory, and programmable logic devices. Atmel was an independent company until its acquisition by Microchip Technology in 2016.

Application areas of ATF1504ASV-15AU100:
- Fixed-function, non-volatile logic for telecom and data-communications (protocol engines, interface controllers, glue logic).
- Aerospace/Defense and space electronics (radiation-tolerant, rugged, nonvolatile configuration).
- Automotive and industrial control (long lifecycle, reliable operation in harsh environments).
- Embedded systems needing compact, low-power, nonvolatile hardware with security.
- Low-volume ASIC replacement or fixed-function accelerators where reconfiguration is not required.

It uses a 100-pin LQFP (Thin Quad Flat Pack) package.
