Product details
Overview
ATF1502ASV-15JU44 from Atmel (now Microchip) is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 32 macrocells, 44-pin TQFP package, 15 ns maximum pin-to-pin delay, and 3.0–3.6 V operation. It supports in-system programming via IEEE 1149.1 JTAG, delivers registered operation up to 77 MHz, and integrates global clock, clear, and output enable functions for embedded control logic replacement.
For engineers reviewing the ATF1502ASV-15JU44 datasheet, ATF1502ASV-15JU44 pinout, ATF1502ASV-15JU44 application, or ATF1502ASV-15JU44 equivalent, this device serves as a RoHS-compliant, lead- and halide-free CPLD for legacy system upgrades, industrial I/O expansion, and PCI-compliant glue logic where deterministic timing, EEPROM-based nonvolatility, and field-programmable logic integration are required.
Technical Context
The ATF1502ASV-15JU44 implements a flexible macrocell architecture with five product terms per macrocell-expandable to 40 via cascade logic-and supports combinatorial or registered outputs with buried feedback. Its switch matrix selects up to 40 signals from a global bus fed by all I/O pins and macrocell feedback paths.
It features three dedicated global clock inputs (GCLK1–GCLK3), two power-down pins (PD1/PD2), four JTAG boundary-scan pins (TDI/TMS/TCK/TDO), and programmable pin-keeper circuits. The device operates across industrial temperature range (–40°C to +85°C) and supports both standard and reduced-power macrocell modes.

Pinout & Package
ATF1502ASV-15JU44 is packaged in a 44-lead Thin Quad Flat Package (TQFP), RoHS-compliant, with 0.8 mm lead pitch and exposed thermal pad (not electrically connected). Pin 1 is marked by dot or notch; package dimensions are 10 mm × 10 mm × 1.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 26, 32 | TDI / TMS / TCK / TDO | JTAG boundary-scan and ISP interface - must be reserved if in-system programming or test is enabled |
| 4, 16, 24, 36 | GND | Ground reference for core and I/O - requires low-inductance PCB routing to minimize noise |
| 9, 17, 29, 41 | VCCI | 3.3 V core/I/O supply - decoupling capacitors (0.1 µF + 4.7 µF) required at each pin |
| 37, 39, 40 | GCLK1 / GCLR / OE2 | Dedicated global clock, asynchronous clear, and output enable - drive internal control networks with minimal skew |
| 5, 19 | PD1 / PD2 | Power-down control inputs - assert high to reduce ICC to ≤0.75 mA while latching register and output states |
| 35, 38 | GCLK3 / TDO | Multi-function pin: global clock input or JTAG data output - configured at compile time |
| 2–3, 6, 8–15, 18, 20–23, 25, 27–34, 36, 41–44 | I/O | Bi-directional user-configurable pins - support programmable slew rate, open-collector, and pin-keeper options |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability (ISP) | IEEE 1149.1 JTAG interface enables field reprogramming without device removal - critical for post-deployment logic fixes |
| Programmable Pin-keeper | Eliminates need for external pull-ups on unused I/Os - reduces BOM cost and board space while preventing floating-input-induced shoot-through |
| Per-macrocell Power Control | Reduced-power bit disables unused logic resources - cuts standby current by up to 40% versus standard mode |
| Security Fuse | One-time programmable fuse blocks readback of configuration - protects IP in deployed systems against reverse engineering |
| PCI Compliance | Meets electrical and timing requirements for Peripheral Component Interconnect - enables direct integration into PCI add-in cards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1502ASV-15AI44 | Same die, industrial-grade screening (–40°C to +85°C), but leaded PLCC-44 package | Requires socket or rework for TQFP-to-PLCC adapter; lacks RoHS compliance | Select only if legacy PLCC assembly infrastructure exists and halogen-free requirement is waived |
| XCR3064XL-10VQ44C | Xilinx CoolRunner-II CPLD: 64 macrocells, 10 ns delay, 3.3 V, but no built-in power-down pins or pin-keeper option | Higher density but lacks PD1/PD2 control and requires external keepers for floating I/Os | Choose when additional logic capacity is needed and power-down functionality is handled externally |
Compared with ATF1502ASV-15AI44 and XCR3064XL-10VQ44C, the ATF1502ASV-15JU44 uniquely combines industrial temperature rating, halide-free TQFP packaging, integrated power-down control, and programmable pin-keepers - making it optimal for cost-sensitive, field-upgradable industrial controllers where board space and long-term supply stability are critical.
