Product details
Overview
ATF1504AS-10JC44 from Microchip (formerly Atmel) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 64 macrocells, 5 product terms per macrocell (expandable to 40), 7.5 ns pin-to-pin delay, and support for 125 MHz registered operation. It implements flexible logic functions in industrial control, legacy interface bridging, and board-level glue logic where in-system programmability and PCI compliance are required.
For engineers reviewing the ATF1504AS-10JC44 datasheet, ATF1504AS-10JC44 pinout, ATF1504AS-10JC44 application, or ATF1504AS-10JC44 equivalent, key selection criteria include JTAG ISP capability, 44-pin TQFP package compatibility, 3.3V/5V I/O flexibility, power-down mode via PD pins, and macrocell-level reduced-power configuration for embedded systems with thermal or supply constraints.
Technical Context
The ATF1504AS-10JC44 employs a global bus architecture feeding up to 40 signals into each logic block's switch matrix, enabling high routing utilization and pin-locked design revisions. Its macrocell structure integrates OR/XOR/CASCADE logic, configurable D/T/latch flip-flops, and foldback feedback to regional buses for efficient sum-of-products generation.
It supports IEEE 1149.1 JTAG boundary-scan testing and in-system programming via TDI/TDO/TMS/TCK pins, with optional pull-ups on TMS/TDI. The device includes three global clock inputs (GCLK1–GCLK3), global clear (GCLR), two output enable pins (OE1/OE2), and input transition detection (ITD) circuits on clocks, inputs, and I/Os.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3064XL-10VQ44C | 64 macrocells, 10 ns delay, 3.3V-only I/O, no 5V tolerance | Lacks 5V I/O compatibility and PCI compliance; lower ESD rating (2000V vs. 2000V same) | Choose for cost-sensitive 3.3V-only designs where legacy bus interfacing is unnecessary |
| EPM3064ATC44-10 | 64 macrocells, 10 ns delay, 3.3V core/5V-tolerant I/O, but no JTAG ISP (requires UV erasure) | Non-reprogrammable in-system; lacks power-down mode and pin-keeper circuits | Choose only for fixed-function, high-volume production where field updates are not required |
Compared with XCR3064XL-10VQ44C and EPM3064ATC44-10, the ATF1504AS-10JC44 uniquely combines 5V/3.3V I/O flexibility, JTAG ISP, PCI compliance, and per-macrocell power control - making it the only option supporting both legacy interface adaptation and low-power embedded control in a single reprogrammable device.

FAQ
What is the operating voltage range supported by the ATF1504AS-10JC44?
The ATF1504AS-10JC44 supports dual I/O voltage operation: 3.0V–3.6V for 3.3V mode or 4.5V–5.5V for 5.0V mode, with separate VCCINT/VCCIO rails. This allows direct interfacing with both legacy 5V TTL peripherals and modern 3.3V microcontrollers without level shifters. The ATF1504AS-10JC44 does not support mixed-voltage operation on a single I/O bank - all I/Os share the same VCCIO setting.
Does the ATF1504AS-10JC44 require external pull-up resistors on JTAG pins?
No - the ATF1504AS-10JC44 includes programmable internal pull-up resistors on TMS and TDI pins, which can be enabled during design compilation. This eliminates the need for external components and simplifies PCB layout. The ATF1504AS-10JC44 retains full JTAG functionality (boundary-scan and ISP) with or without these pull-ups enabled, provided the target system meets IEEE 1149.1 voltage thresholds.
How does the power-down mode function on the ATF1504AS-10JC44?
When enabled in the design file, the ATF1504AS-10JC44 enters power-down mode when PD1 (pin 44) is driven high, reducing supply current to <10 mA. All internal logic states and output levels are latched and held; inputs (except PD1) are blocked. The ATF1504AS-10JC44 resumes normal operation within 1 µs after PD1 returns low, with no loss of configuration. PD1 cannot serve as a logic I/O while power-down is active.
Can the ATF1504AS-10JC44 be used in PCI-compliant designs?
Yes - the ATF1504AS-10JC44 meets PCI electrical specifications for output drive strength, timing skew, and voltage levels, enabling direct connection to PCI bus lines without external buffers. Its 5V-tolerant I/O and programmable slew rate control ensure signal integrity across loaded backplanes. The ATF1504AS-10JC44 has been validated in PCI add-in cards for industrial and test equipment applications.
What is the purpose of the User Signature feature in the ATF1504AS-10JC44?
The ATF1504AS-10JC44 includes 16 bits of user-accessible signature memory that remains readable even when the security fuse is programmed. Engineers use this space to store project identifiers, revision numbers, or date codes - enabling traceability across firmware versions and production batches. The ATF1504AS-10JC44 allows read/write access to this field via JTAG or programming software without affecting device configuration.
