Product details
Overview
ATF1502AS-10JC44 from Atmel is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) with 32 macrocells, 5 product terms per macrocell (expandable to 40), 44-pin TQFP package, 7.5 ns maximum pin-to-pin delay, and registered operation up to 125 MHz. It integrates TTL/SSI/MSI logic in industrial control, PCI interface bridging, and legacy system replacement applications.
For engineers reviewing the ATF1502AS-10JC44 datasheet, ATF1502AS-10JC44 pinout, ATF1502AS-10JC44 application, or ATF1502AS-10JC44 equivalent, key selection considerations include JTAG ISP capability, PCI-compliant 5V I/O drive, programmable slew rate, global clock architecture with three GCLK pins, and power-down mode via PD1/PD2 pins.
Technical Context
The ATF1502AS-10JC44 implements a macrocell-based architecture with dedicated global routing resources, including a 40-signal global bus fed by all I/Os and macrocell feedback, plus regional foldback buses enabling up to nine-product-term sum terms per region. Each macrocell supports D/T-latch configurable flip-flops, XOR-based arithmetic/comparison, and buried registered feedback independent of output configuration.
Its JTAG interface complies with IEEE Std. 1149.1-1990/1149.1a-1993 for boundary-scan testing and in-system programming, while PCI compliance is achieved through programmable high-drive outputs delivering ±44 mA AC sink/source at defined voltage points without added skew. Input Transition Detection (ITD) circuits on global clocks, inputs, and I/Os enable advanced power management.

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, 3.3V core, 5V-tolerant I/O, 7.5 ns propagation delay, Xilinx CoolRunner-II architecture | Higher density and lower static power, but requires level-shifting for pure 5V systems | Select when migrating to 3.3V infrastructure or needing >32 macrocells; not pin-compatible with ATF1502AS-10JC44 |
| EPM3064ATC44-10 | 64 macrocells, 3.3V supply, 10 ns tPD, Intel MAX 3000A family, no native PCI drive spec | Higher gate count and better toolchain support, but lacks built-in PCI-compliant drive curves | Choose for cost-sensitive 3.3V designs where PCI compliance is handled externally; requires PCB redesign |
Compared with XCR3064XL-10VQ44C and EPM3064ATC44-10, the ATF1502AS-10JC44 uniquely delivers native 5V operation, integrated PCI drive capability, and JTAG ISP in a 44-pin TQFP-making it optimal for direct replacement of legacy 5V PLDs without voltage translation or layout change.

FAQ
What is the maximum operating frequency of the ATF1502AS-10JC44?
The ATF1502AS-10JC44 supports registered operation up to 125 MHz, verified by its -10 speed grade designation and 7.5 ns maximum pin-to-pin delay. This frequency applies to global clock domains (GCLK1–3); array clock paths support the same 125 MHz maximum under specified load and voltage conditions. The ATF1502AS-10JC44 achieves this performance while maintaining full 5V I/O compatibility and PCI electrical compliance.
Does the ATF1502AS-10JC44 support in-system programming (ISP)?
Yes, the ATF1502AS-10JC44 fully supports in-system programming via its 4-pin JTAG interface compliant with IEEE Std. 1149.1-1990 and 1149.1a-1993. Programming can be performed without removing the device from the PCB using standard SVF files and third-party tools. The ATF1502AS-10JC44 retains full logic functionality on its JTAG pins when ISP is disabled, allowing all four pins (TDI, TDO, TMS, TCK) to serve as general-purpose I/O.
What power management features does the ATF1502AS-10JC44 offer?
The ATF1502AS-10JC44 provides three distinct power-saving modes: automatic 10 µA standby (for "L" versions only), pin-controlled 1 mA standby via PD1/PD2, and per-macrocell reduced-power configuration. It also includes Input Transition Detection (ITD) on clocks and I/Os to gate unused logic sections dynamically. The ATF1502AS-10JC44 does not implement the automatic 10 µA standby mode - that feature is exclusive to the ATF1502ASL variant.
Is the ATF1502AS-10JC44 compatible with PCI bus specifications?
Yes, the ATF1502AS-10JC44 is explicitly designed for PCI compliance, meeting key electrical requirements including VOH ≥2.4 V at -2 mA, VOL ≤0.55 V at 3–6 mA, and AC switching currents of ±44 mA (sink/source) within defined voltage windows. Its programmable high-drive outputs deliver PCI-level current without increasing output skew or pin capacitance - a capability confirmed in the official Atmel datasheet Rev. 0995J–PLD–09/02 for the ATF1502AS-10JC44.
What is the purpose of the User Signature area in the ATF1502AS-10JC44?
The ATF1502AS-10JC44 includes two bytes (16 bits) of User Signature memory accessible regardless of security fuse state. This non-volatile storage allows designers to embed project identifiers, part revisions, build dates, or calibration data directly into the device configuration. The User Signature remains readable after programming and persists across power cycles, providing traceability without compromising intellectual property protection enforced by the security fuse.
