Product details
Overview
ATF750C-15GM/883 from Atmel is a high-performance, electrically-erasable complex programmable logic device (CPLD) in a 24-lead ceramic DIP package, delivering 15 ns maximum pin-to-pin delay, 20 registered outputs with individually configurable D/T-type flip-flops, and full military-grade operation from –55°C to +125°C. It implements state machines, glue logic, and bus interface control in avionics and ruggedized embedded systems.
For engineers reviewing the ATF750C-15GM/883 datasheet, ATF750C-15GM/883 pinout, ATF750C-15GM/883 application, or ATF750C-15GM/883 equivalent, this page provides verified timing parameters, military qualification details, pin-keeper circuit behavior, product-term clocking architecture, and direct replacement guidance for ATV750B/BL and ATV750/L designs.
Technical Context
The ATF750C-15GM/883 implements a 22-input, 20-output CPLD architecture with 171 total product terms, two sum terms per output, and variable product-term allocation (4–8 per sum term). Its logic array supports buried flip-flops, independent feedback paths, and asynchronous reset per register.
It features dual clocking modes: product-term-derived clocks for flexible timing control and direct input-pin clocking (CLK/IN on Pin 1) for high-speed synchronous operation. All 20 flip-flops feed back into the array, enabling full internal state retention without external latches.
Key Specifications

| Erase/Write Cycles | 1000 cycles - supports reprogramming in depot-level repair and firmware updates |
Pinout & Package
ATF750C-15GM/883 uses the 24-lead, 0.300" wide, non-windowed ceramic dual-inline package (CerDIP), designated 24D3 per MIL-STD-1835 D-9 Config A. This hermetically sealed package ensures long-term reliability in high-vibration, high-humidity, and radiation-prone environments.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK/IN | Primary clock input or general logic input; enables direct-pin clocking for highest-speed register updates |
| 2–12 | IN | Dedicated logic inputs; all 11 pins support full array routing and product-term generation |
| 13 | GND | Ground reference for analog and digital sections; must be connected per MIL-STD-883 layout guidelines |
| 14–23 | I/O | Bi-directional I/O pins; each configurable as input, output, or registered output with individual OE control |
| 24 | VCC | +5V supply pin; requires local 0.1 µF ceramic decoupling per MIL-HDBK-454A |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Pin-keeper Circuits | Eliminates need for external pull-ups on unused I/Os, reducing BOM count and DC leakage in unpowered states |
| Selectable D- or T-type Flip-flops | Enables efficient JK/SR synthesis and reduces product-term usage for counter/state-machine logic |
| Individual Asynchronous Reset per Flip-flop | Allows selective initialization of subsystems without global reset propagation delays |
| Power-up Reset Function | Guarantees known low-state register initialization at VCC > 2.0 V, critical for deterministic boot sequencing |
| 14,504 JEDEC Fuses | Supports full logic reconfiguration and security fuse programming to prevent unauthorized design cloning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-10GM/883 | 7.5 ns faster max pin-to-pin delay (10 ns vs. 15 ns); identical package, temperature range, and logic architecture | Suitable where tighter setup/hold margins or higher fMAX (71 MHz vs. 55 MHz) are required in timing-critical control loops | Select when system clock rates exceed 50 MHz or when interfacing with sub-10 ns ASICs/FPGAs |
| ATF750C-15NM/883 | Same speed grade and temperature rating, but in 28-lead PLCC (28J) instead of CerDIP (24D3); different pinout and thermal profile | Better suited for surface-mount production and automated optical inspection, but lacks hermetic sealing | Choose for volume-manufactured ground-system electronics where RoHS compliance and SMT yield outweigh hermeticity needs |
Compared with ATF750C-10GM/883, the ATF750C-15GM/883 trades 5 ns of speed for broader voltage margin tolerance and lower dynamic power; compared with ATF750C-15NM/883, it delivers superior thermal stability and moisture resistance via ceramic packaging-critical for airborne and naval deployments.

FAQ
What is the maximum operating frequency supported by ATF750C-15GM/883?
The ATF750C-15GM/883 supports up to 55 MHz in external feedback mode (1/(tSS + tCOS)) and 83 MHz in no-feedback mode (1/tPS), as specified in its AC characteristics table for the -15 speed grade. These values are guaranteed across the full –55°C to +125°C military temperature range and 5V ±10% supply, making ATF750C-15GM/883 suitable for deterministic real-time control in hardened platforms.
Does ATF750C-15GM/883 support in-system programming?
No-ATF750C-15GM/883 requires external parallel programming via a standard JEDEC programmer using 14,504 fuses. It does not support ISP or JTAG. Programming voltage is +12.5V applied to Pin 8 (DIP) or Lead 10 (SMD) during preload cycles, and the security fuse prevents post-programming readback. ATF750C-15GM/883 is programmed before board assembly or during depot-level rework.
How does the pin-keeper function operate on ATF750C-15GM/883?
The pin-keeper circuits on ATF750C-15GM/883 are programmable per-pin via compiler settings (e.g., V750CPPK in WinCUPL). When enabled, they hold last-driven logic state (high/low) on floating inputs/I/Os using weak keeper transistors-eliminating external pull resistors and reducing standby current. This feature is active only after configuration and remains functional across the full military temperature range.
Is ATF750C-15GM/883 pin-compatible with ATV750B/BL devices?
Yes-ATF750C-15GM/883 is a direct replacement for ATV750B/BL in the same 24D3 package, supporting identical pinout, JEDEC file compatibility (V750B mode), and backward functionality. It adds T-type flip-flops, pin-clocking, and enhanced product-term routing-but retains full electrical and mechanical compatibility for drop-in upgrades in legacy MIL-STD-883 designs.
What is the power-up reset behavior of ATF750C-15GM/883?
ATF750C-15GM/883 performs automatic power-up reset: all 20 registers initialize to logic low when VCC crosses 2.0–4.5 V (VRST), with reset duration of 600–1000 ns (tPR). This behavior is asynchronous and requires monotonic VCC ramp-up and adherence to input setup times before first clock edge-ensuring deterministic state-machine startup in safety-critical avionics and weapon systems.
