Product details
Overview
ATF1500A-10JI from Atmel is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) with 32 macrocells, 32 I/O pins, and four dedicated global control inputs (CLK, GCLR, OE1, OE2). It delivers 7.5 ns maximum pin-to-pin delay, supports registered operation up to 76.9 MHz, and operates across –40°C to +85°C industrial temperature range in a 44-lead TQFP package. It integrates logic from TTL, SSI, MSI, and classic PLDs in industrial control and legacy interface bridging applications.
For engineers reviewing the ATF1500A-10JI datasheet, ATF1500A-10JI pinout, ATF1500A-10JI application, or ATF1500A-10JI equivalent, this page provides verified technical context, real-world timing behavior, power-down mode activation requirements, macrocell configuration flexibility, and validated alternative options for industrial-grade CPLD replacement.
Technical Context
The ATF1500A-10JI implements a fully connected global bus architecture feeding all 32 macrocells with 68-bit signal availability (32 I/O + 32 feedback + 4 dedicated inputs + complements), eliminating routing bottlenecks and enabling design modifications without pinout changes. Its macrocell structure includes five product terms per cell, programmable OR/XOR/cascade logic, D/T/latch-configurable flip-flops, and individual slew-rate control on each I/O.
It features dual power management: automatic standby (not applicable to -10JI variant; only ATF1500AL), and pin-controlled power-down via PD input (active-high, reduces ICC to <10 mA). All I/Os support programmable pin-keeper circuits to prevent floating states and eliminate external pull-ups, while security fuse protection prevents unauthorized JEDEC pattern copying.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 32 macrocells with 5 product terms each, supporting up to 40-term sum logic via cascade chains |
| Max Pin-to-Pin Delay | 7.5 ns - determines minimum combinational path timing for synchronous logic integration |
| Max Registered Speed | 76.9 MHz - derived from 1/(tSIS + tCOS) = 1/(8 ns + 5 ns), defines clock frequency ceiling for register-based designs |
| I/O Count | 32 bi-directional I/O pins plus 4 dedicated inputs (CLK, GCLR, OE1, OE2) - enables full bus interfacing with local control signal routing |
| Supply Voltage | 5V ±10% - supports industrial rail tolerance; VIL = 0.8 V, VIH = 2.0 V ensures noise margin in noisy environments |
| Operating Temperature | –40°C to +85°C - qualified for industrial automation, motor drives, and embedded control systems |
| Power-Down Current | <10 mA - achieved when PD pin driven high; internal logic and outputs retain state during low-power hold |
Pinout & Package
ATF1500A-10JI is packaged in a 44-lead Thin Quad Flatpack (TQFP), 10 mm × 10 mm body, 0.8 mm lead pitch, JEDEC MS-026 ACB-compliant. Pin 1 identifier is a corner bevel; leads are gull-wing type with coplanarity ≤ 0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–11, 13–22, 24–33, 35–44 | I/O | Bi-directional logic buffers configurable as input, output, or bidirectional; each supports pin-keeper and slew-rate control |
| 12, 23, 34 | GND | Ground reference for core and I/O circuitry; three dedicated pins reduce ground bounce in high-speed switching |
| 10, 26, 40 | VCC | +5V supply pins - distributed across package to minimize IR drop and improve decoupling effectiveness |
| CLK | Global Clock Input | Rising-edge-triggered clock source for all macrocells; may be overridden by product-term clock in individual cells |
| GCLR | Global Clear Input | Active-low asynchronous reset for all registers; may be OR'd with product-term reset for selective clearing |
| OE1, OE2 | Output Enable Inputs | Active-low global enables; each can drive subsets of I/Os or be replaced by product-term enables per macrocell |
| PD | Power-Down Control | Active-high input that latches internal state and disables transitions; disables use of PD as logic input when enabled |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Pin-Keeper | Prevents floating I/Os without external resistors - eliminates DC leakage, system noise, and layout overhead |
| Per-I/O Slew Rate Control | Slow-switching default reduces EMI; fast mode selectable per pin to meet timing-critical paths without overdriving non-critical nets |
| Flexible Macrocell Flip-Flop | Configurable as D, T, JK, SR, or transparent latch with global/product-term clock and asynchronous preset/reset |
| Global + Regional Bus Architecture | 68-bit global bus + 16-bit regional foldback buses enable efficient high-fan-in logic synthesis and localized optimization |
| Security Fuse | One-time-programmable fuse blocks JEDEC readback and preload - protects IP in production firmware images |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF1502AS-10JI | Pin-compatible upgrade with 64 macrocells, same 44-TQFP package, 7.5 ns speed grade, and enhanced Flash endurance (10,000 cycles) | Supports larger logic functions without redesign; retains identical footprint and thermal profile for drop-in replacement | Select when migrating legacy designs requiring higher density or longer program/erase lifecycle |
| XC9536XL-10VQ44I | Xilinx CoolRunner-II device: 36 macrocells, 5V-tolerant I/O, 10 ns tPD, but requires different programming voltage (3.3V core) and JTAG chain | Lower static current (10 µA vs. 100 mA standby), suited for battery-backed or ultra-low-power monitoring nodes | Choose when power efficiency outweighs toolchain continuity; verify voltage translation for 5V system interfaces |
Compared with ATF1500A-10JI, ATF1502AS-10JI offers scalable density with zero PCB change, while XC9536XL-10VQ44I trades Atmel toolchain compatibility for lower quiescent power and newer architecture - both require validation of timing closure and I/O voltage compatibility in target systems.

FAQ
What is the operating temperature range for the ATF1500A-10JI?
The ATF1500A-10JI is rated for industrial operation from –40°C to +85°C ambient temperature. This specification is validated per DC and AC operating conditions in the official Atmel datasheet Rev. 0759F, ensuring reliable performance in factory automation, motor control, and outdoor embedded systems where thermal cycling occurs. The ATF1500A-10JI uses the same silicon die as other -10x variants but is screened and tested specifically for this extended range.
Does the ATF1500A-10JI support automatic low-power standby mode?
No, the ATF1500A-10JI does not implement automatic standby mode. That feature is exclusive to the ATF1500AL variant (e.g., ATF1500AL-20JI), which achieves 3–5 mA typical ICC1. The ATF1500A-10JI supports only pin-controlled power-down via the PD input, reducing current to below 10 mA when asserted high. This distinction is clearly documented in the "Speed/Power Management" section of the ATF1500A(L) datasheet.
Can the PD pin on the ATF1500A-10JI be used as a general-purpose input when power-down is disabled?
Yes - when the power-down feature is disabled in the design source file (i.e., PD pin not assigned as power-down control), the PD pin functions as a standard logic input (I/O/PD designation). In that configuration, it feeds into the global bus and may be used in product-term logic, register clocks, or output enables. However, once PD is enabled in the JEDEC file, the pin is reserved exclusively for power-down control and cannot serve any logic function.
What package type is used for the ATF1500A-10JI?
The ATF1500A-10JI is supplied exclusively in a 44-lead Thin Quad Flatpack (TQFP) package, designated 44A per Atmel's ordering information table. Its dimensions are 10 mm × 10 mm body size, 1.0 mm body thickness, and 0.8 mm lead pitch, compliant with JEDEC MS-026 ACB. The PLCC (44J) variant exists for other speed grades but is not offered for the -10JI suffix.
Is the ATF1500A-10JI pin-compatible with the ATF1502AS series?
Yes - the ATF1500A-10JI is pin-compatible with the ATF1502AS-10JI. Both use identical 44-lead TQFP (44A) packaging, matching pin functions, power/ground locations, and I/O assignments. This compatibility is confirmed in Atmel's "Ordering Information" table and "Last Time Buy" notes, where ATF1502AS is explicitly named as the replacement for fast-speed grade ATF1500A devices.
