Product details
Overview
ATF750C-15NM/883 from Atmel is a high-performance, electrically-erasable complex programmable logic device (CPLD) in a 28-pin LCC package, delivering 15 ns maximum pin-to-pin delay at 5V, 20 flip-flops (D/T-configurable), 171 product terms, and full military temperature operation (–55°C to +125°C). It serves as a superset of the 22V10 with enhanced logic flexibility and backward compatibility with ATV750B/BL and ATV750/L, used in legacy avionics control and missile guidance interface logic.
For engineers reviewing the ATF750C-15NM/883 datasheet, ATF750C-15NM/883 pinout, ATF750C-15NM/883 application, or ATF750C-15NM/883 equivalent, key selection criteria include military-grade reliability, 20-year data retention, 1000 erase/write cycles, programmable pin-keeper circuits, and dual clocking modes (product-term or direct input pin).
Technical Context
The ATF750C-15NM/883 implements a 22-input × 20-output PLD architecture with 42 array inputs, 20 sum terms, and fully independent feedback paths for all 20 flip-flops. Its logic array supports configurable D- or T-type registers per flip-flop, individual asynchronous reset per register, and synchronous preset for all registers.
It features two distinct clocking architectures: product-term-derived clocks (tCO = 5 ns max) and direct input pin clocks (tCOS = 10 ns max), enabling mixed-clock domain state machines. Pin-keeper circuits are programmable per I/O to eliminate floating inputs without external pull-ups.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-15GM/883 | Same speed grade (15 ns), but in 24D3 CerDIP package instead of 28L LCC | Preferred where through-hole mounting and higher mechanical robustness are required over surface-mount density | Select when board assembly uses wave soldering or requires higher shock/vibration tolerance |
| ATF750CL-15NM/883 | Low-power variant with 1 mA standby current vs. standard ATF750C's 135–190 mA | Suitable for battery-backed subsystems or thermally constrained enclosures where active power must be minimized | Choose only if system-level power budget mandates sub-mA standby; performance otherwise identical |

FAQ
What is the maximum operating frequency of the ATF750C-15NM/883 under internal feedback conditions?
The ATF750C-15NM/883 achieves a maximum operating frequency of 62 MHz under internal feedback conditions (1/(tSF + tCF)), as specified in AC Characteristics Table 16. This value reflects worst-case timing across the full –55°C to +125°C military temperature range and 5V ±10% supply, ensuring reliable operation in demanding embedded control applications where the ATF750C-15NM/883 is deployed.
Does the ATF750C-15NM/883 support both D-type and T-type flip-flop configurations?
Yes, each of the 20 flip-flops in the ATF750C-15NM/883 can be individually configured as either D-type or T-type via programming, enabling efficient implementation of JK and SR functions. This configurability is confirmed in Sections 6 and 23 of the datasheet and directly impacts product term utilization efficiency in the ATF750C-15NM/883 logic design.
What package type is used for the ATF750C-15NM/883, and what are its key mechanical attributes?
The ATF750C-15NM/883 uses the 28L package: a 28-pad, non-windowed ceramic leadless chip carrier (LCC) with dimensions 11.68 mm × 11.68 mm and 1.91 mm height. Per Section 33.3, it conforms to MIL-STD-1835 C-4 and provides hermetic sealing, thermal stability, and compatibility with infrared reflow profiles used in defense PCB assembly - critical for the ATF750C-15NM/883's intended use cases.
How does the pin-keeper function operate on the ATF750C-15NM/883, and is it enabled by default?
The pin-keeper circuits on the ATF750C-15NM/883 are programmable per I/O pin and are disabled by default. When enabled (via WinCUPL device selection such as V750CPPKLCC), they hold the last driven logic state on floating inputs/I/Os, eliminating external pull-up resistors. This behavior is documented in Section 9 and directly affects power consumption and noise immunity in the ATF750C-15NM/883's operational environment.
Is the ATF750C-15NM/883 compatible with legacy ATV750B/BL designs without modification?
Yes, the ATF750C-15NM/883 is explicitly backward compatible with ATV750B/BL and ATV750/L, as stated in the Features section and Section 25. It supports cross-programming via V750B JEDEC files and maintains identical pinout and functional subset behavior - making the ATF750C-15NM/883 a drop-in speed and feature upgrade for existing ATV750-based systems.
