Product details
Overview
ATF1500A-15JC from Atmel is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 32 I/O pins, 7.5 ns maximum pin-to-pin delay, and registered operation up to 125 MHz. It features flexible macrocells supporting D/T/latch flip-flops, programmable slew rate, pin-keeper inputs, and global/regional bus architecture for efficient logic placement in embedded control and interface logic applications.
For engineers reviewing the ATF1500A-15JC datasheet, ATF1500A-15JC pinout, ATF1500A-15JC application, or ATF1500A-15JC equivalent, key selection considerations include its 44-pin TQFP package, -15 speed grade (tPD = 15 ns), industrial temperature range (-40°C to +85°C), 5 V supply, and Flash-based reprogrammability with 100 program/erase cycles.
Technical Context
The ATF1500A-15JC implements a fully connected global bus feeding all 32 macrocells, each with five product terms, OR/XOR/cascade logic, and configurable D/T/latch flip-flops. Its architecture supports both external and internal feedback paths, enabling 125 MHz registered operation with tSFS + tCFS = 11 ns minimum cycle time.
It integrates four independent cascade chains (up to 40 product terms per chain), programmable pin-keeper circuits on all I/Os, and optional pin-controlled power-down mode reducing ICC to <10 mA. The device uses advanced Flash technology with 20-year data retention, 2000V ESD protection, and RoHS-compliant packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 32 macrocells with 36 total inputs and 32 I/Os - supports integration of multiple TTL/SSI/MSI functions in one device |
| Propagation Delay (tPD) | 15 ns max - defines worst-case combinatorial path timing for synchronous design closure at ≤52.6 MHz |
| Maximum Clock Frequency | 125 MHz with internal feedback - enables high-speed state machines and counters without external timing constraints |
| Supply Voltage | 5 V ±5% - requires stable 5 V rail; not compatible with 3.3 V or mixed-voltage systems without level translation |
| Operating Temperature | -40°C to +85°C - qualified for industrial environments including factory automation and motor control |
| Program/Erase Cycles | 100 cycles - supports field firmware updates and iterative logic revisions during prototyping and maintenance |
| Data Retention | 20 years - ensures long-term reliability in unattended or mission-critical embedded deployments |
Pinout & Package
ATF1500A-15JC is housed in a 44-lead Thin Quad Flatpack (TQFP) package, 10 mm × 10 mm body, 0.8 mm lead pitch, JEDEC MS-026 ACB compliant. Pin 1 identifier is a corner notch or dot; top view shown with standard I/O, power, and control pin assignments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Global clock input | Primary synchronous edge-trigger source for all macrocell registers; rising-edge sensitive |
| GCLR | Asynchronous global clear (active low) | Resets all macrocell flip-flops simultaneously; used for system-level initialization or fault recovery |
| OE1, OE2 | Output enable (active low) | Individually or globally controls tri-state output drivers; supports bus-sharing and hot-swap isolation |
| PD | Power-down control (active high) | Enters <10 mA standby when asserted; latches outputs and internal states; disables all inputs except PD |
| VCC | +5 V supply | Two dedicated pins (pins 9 and 22) - must be decoupled locally with 0.1 µF ceramic capacitors |
| GND | Ground reference | Three dedicated pins (pins 4, 21, 43) - critical for noise suppression and signal integrity in high-speed CPLD operation |
| I/O | Bi-directional logic buffer | All 32 I/O pins support programmable direction, slew rate, and pin-keeper; default as inputs after configuration |
Key Features
| Feature | Design Value |
|---|---|
| Flexible macrocell configuration | Each of 32 macrocells supports D/T/latch flip-flop modes, individual clock enable, and asynchronous preset/reset - enables precise state machine and counter implementation |
| Programmable output slew rate | Per-I/O slow/fast selection reduces EMI and crosstalk on non-critical signals while preserving timing on high-speed paths |
| Pin-keeper circuitry | Prevents floating I/Os from drifting to indeterminate voltage levels - eliminates need for external pull-ups and associated DC power loss |
| Flash-based reprogrammability | 100 verified program/erase cycles with 20-year data retention - supports field updates and design iteration without hardware change |
| Security fuse | One-time programmable fuse blocks unauthorized readback of JEDEC fuse pattern - protects IP in production systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1502AS-15JU | Pin-compatible upgrade with green (Pb/Halide-free) PLCC-44 package; same 15 ns speed grade but enhanced ESD (3000 V) and latch-up immunity (250 mA) | Required for new designs targeting RoHS compliance; supports identical logic density and timing but with updated process and packaging | Select when replacing ATF1500A-15JC in new industrial designs requiring halogen-free materials and extended reliability specs. |
| XC9536XL-10VQ44C | Xilinx CoolRunner-II CPLD; 36 macrocells, 10 ns tPD, 3.3 V supply; no native 5 V tolerance - requires level-shifting for legacy 5 V systems | Better suited for low-power, battery-operated, or mixed-voltage systems where 5 V compatibility is not mandatory | Choose only if migrating to 3.3 V infrastructure and accepting toolchain transition; not a drop-in replacement due to voltage and programming differences. |
Compared with ATF1500A-15JC, ATF1502AS-15JU offers identical functionality with improved environmental compliance and robustness, while XC9536XL-10VQ44C trades 5 V compatibility and Flash reprogrammability for lower static power and newer architecture - making it suitable only for green-field 3.3 V designs.

FAQ
What is the operating temperature range for ATF1500A-15JC?
The ATF1500A-15JC is rated for industrial temperature operation from -40°C to +85°C. This specification is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official Atmel datasheet (Rev. 0759F). The "I" suffix in the ordering code denotes industrial grade, and the -15 speed grade applies across this full range. Designers must ensure thermal management maintains junction temperature within limits under worst-case power dissipation.
Does ATF1500A-15JC support in-system programming?
Yes, ATF1500A-15JC supports in-system programming via JTAG IEEE 1149.1 interface. The device includes dedicated TCK, TMS, TDI, and TDO pins (mapped to PLCC/TQFP pins per package drawing), and is compatible with standard Atmel ICE and third-party programmers. Programming does not require socket removal, enabling field firmware updates and logic revisions without hardware intervention - a core feature of the ATF1500A Flash architecture.
What is the purpose of the PD pin on ATF1500A-15JC?
The PD (Power-Down) pin on ATF1500A-15JC is an active-high control input that places the device into a low-current standby mode (<10 mA) when asserted. In this state, all internal logic states and output levels are latched and held, and all inputs except PD are ignored. The PD function must be enabled in the design source file; once enabled, the PD pin cannot serve as a general-purpose logic input or I/O, though its macrocell resources remain usable for foldback logic.
Can ATF1500A-15JC operate with a 3.3 V supply?
No, ATF1500A-15JC requires a nominal 5 V ±5% supply (VCC = 4.75 V to 5.25 V). Its I/O structure, internal logic thresholds, and Flash programming voltage are designed exclusively for 5 V operation. Attempting to power ATF1500A-15JC from 3.3 V will result in functional failure, undefined logic states, and inability to configure or retain programmed logic. Level-shifting circuitry is mandatory when interfacing with 3.3 V systems.
How many product terms does each macrocell in ATF1500A-15JC contain?
Each of the 32 macrocells in ATF1500A-15JC contains five dedicated product terms. These terms receive inputs from both the global bus (68-bit, including all I/O and feedback signals) and regional bus (16-foldback terms), enabling flexible AND-OR logic synthesis. The product term select multiplexer (PTMUX) dynamically allocates terms to OR/XOR gates, clock enables, resets, or output enables based on compiler optimization - a defining architectural feature of the ATF1500A family.
