Product details
Overview
ATF1504AS-15AC100 from Microchip Technology (formerly Atmel) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 64 macrocells, 7.5 ns pin-to-pin delay, and 125 MHz registered operation. It supports in-system programming via IEEE 1149.1 JTAG, features three global clock inputs, and operates at 5.0 V ±5% in commercial temperature range (0°C to 70°C). It is used in legacy PCI-compliant interface logic, board-level glue logic consolidation, and industrial control state-machine implementations.
For engineers reviewing the ATF1504AS-15AC100 datasheet, ATF1504AS-15AC100 pinout, ATF1504AS-15AC100 application, or ATF1504AS-15AC100 equivalent, key selection criteria include its 100-lead TQFP package, JTAG boundary-scan compliance, programmable slew rate per output, security fuse protection, and support for both 5V and 3.3V I/O signaling - critical for mixed-voltage system integration and field-upgradable logic designs.
Technical Context
The ATF1504AS-15AC100 implements a hierarchical CPLD architecture with four logic blocks, each fed by a 40-signal global bus and regional foldback buses. Its macrocells feature five product terms expandable to 40 via cascade logic, XOR-based arithmetic/compare capability, and configurable D/T/latch flip-flops with individual clock enable and asynchronous reset/preset.
It integrates IEEE 1149.1a-compliant JTAG boundary-scan test logic, programmable pin-keeper circuits on all I/Os, and dual power-down modes: automatic µA standby (L-version) and pin-controlled 1 mA mode. The device supports PCI-compliant drive strength without external parallelization and includes VCC power-up reset with selectable hysteresis.

FAQ
What is the operating voltage range for ATF1504AS-15AC100?
The ATF1504AS-15AC100 supports two I/O voltage configurations: 5.0 V ±5% (VCCIO = 4.75–5.25 V) for legacy TTL compatibility, and 3.0–3.6 V for low-voltage interfaces. Its core logic (VCCINT) requires 5.0 V ±5%. This dual-voltage capability allows the ATF1504AS-15AC100 to interface directly with both 5V and 3.3V peripherals without external level shifters, simplifying mixed-signal board design.
Does ATF1504AS-15AC100 support JTAG boundary-scan testing?
Yes, the ATF1504AS-15AC100 fully complies with IEEE Std. 1149.1-1990 and 1149.1a-1993 for boundary-scan testing. It includes dedicated TCK, TMS, TDI, and TDO pins with programmable pull-ups on TMS/TDI, and embeds boundary-scan cells on all 68 I/O pins and four dedicated inputs. This enables full interconnect testing and in-system programming without requiring physical access to the device after soldering - a key advantage for the ATF1504AS-15AC100 in densely populated industrial PCBs.
Can ATF1504AS-15AC100 be used in PCI-compliant designs?
Yes, the ATF1504AS-15AC100 meets Peripheral Component Interconnect (PCI) electrical specifications for drive strength, output skew, and timing. Its native high-current output drivers eliminate the need to parallel multiple outputs - a common workaround in other CPLDs. This PCI compliance is verified per the ATF1504AS-15AC100's AC characteristics table and makes it suitable for retrofitting legacy PCI add-in cards where signal integrity and specification adherence are mandatory.
What power management features does ATF1504AS-15AC100 offer?
The ATF1504AS-15AC100 includes three power-saving mechanisms: automatic µA standby (L-version), pin-controlled 1 mA power-down mode via PD1/PD2, and per-macrocell reduced-power bits. When enabled, the latter adds tRPA delay (10–15 ns) but cuts dynamic power significantly. These features allow the ATF1504AS-15AC100 to operate efficiently in battery-powered ATE systems or thermally constrained enclosures while maintaining full logic functionality upon wake-up.
Is ATF1504AS-15AC100 pin-compatible with other ATF1504AS variants?
The ATF1504AS-15AC100 shares identical pinout and package dimensions with other 100-lead TQFP variants (e.g., ATF1504AS-10AC100, ATF1504ASL-15AC100), differing only in speed grade (-15 = 7.5 ns max delay) and temperature grade (C = commercial). This allows direct substitution within the same package footprint when timing margins permit - a key benefit for the ATF1504AS-15AC100 in design reuse and last-time-buy scenarios.
