Product details
Overview
ATF750C-15JI from Atmel is a high-performance, electrically-erasable complex programmable logic device (CPLD) with 20 registered outputs, 42 array inputs, and 171 product terms. It supports D- or T-type flip-flops, pin-to-pin delay of 15 ns at 5V, and operates across industrial temperature range (–40°C to +85°C). It is used in legacy PLD replacement, state machine control, and bus interface logic.
For engineers reviewing the ATF750C-15JI datasheet, ATF750C-15JI pinout, ATF750C-15JI application, or ATF750C-15JI equivalent, this page delivers verified timing specs, confirmed PLCC-28 package mapping, validated I/O flexibility, and real-world CPLD migration guidance for ATV750B/BL and ATV750/L designs.
Technical Context
The ATF750C-15JI implements a 22V10 superset architecture with enhanced logic density: 20 sum terms, 20 flip-flops (individually configurable as D- or T-type), and 171 total product terms. Its programmable clock mux allows each flip-flop to be driven either by dedicated product-term clocks or directly from CLK/IN pin (Pin 1).
It features fully independent feedback paths for all 20 registers and dedicated output-enable product terms per I/O. Pin-keeper circuits are programmable on all input/I/O pins to prevent floating states without external pull-ups, reducing system noise and DC power consumption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 20 sum terms, 20 flip-flops, 171 product terms - enables full state machines and multi-function logic in 24-pin footprint. |
| Max Pin-to-pin Delay | 15 ns at 5V - guarantees deterministic timing for synchronous control paths in industrial systems. |
| Operating Voltage | 5V ±10% - compatible with legacy TTL/CMOS 5V logic families without level-shifting. |
| Temperature Range | –40°C to +85°C - qualified for industrial environments including motor drives and PLC I/O modules. |
| Package | 28-lead PLCC (28J) - surface-mountable, JEDEC MS-018 AB compliant, with standard pinout for drop-in PCB replacement. |
| Data Retention | 20 years - ensures long-term reliability in unattended embedded applications without battery backup. |
| ESD Protection | 2000V HBM - robust against handling and board-level ESD events during manufacturing and field service. |
Pinout & Package
ATF750C-15JI is housed in a 28-lead Plastic J-Leaded Chip Carrier (PLCC-28, package code 28J), with standard JEDEC MS-018 AB pinout. Pin 1 is marked by corner notch; pins 1, 8, 15, and 22 may be left unconnected, though VCC on pin 1 and GND on pins 8, 15, 22 are recommended for optimal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | CLK/IN | Primary clock input or general-purpose logic input; selectable as direct clock source for any flip-flop. |
| Pins 2–12, 23–24 | IN | 12 dedicated input pins; all feed programmable interconnect array and support pin-keeper option. |
| Pins 13–22 | I/O | 10 bi-directional I/O pins; each has individual output-enable product term and internal feedback path. |
| Pin 14 | GND | Ground reference for logic and power domains; multiple GND pins improve noise immunity. |
| Pin 25 | VCC | +5V supply; decoupling near this pin minimizes switching noise in high-speed register transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-mode flip-flops | Each of 20 registers configurable as D- or T-type - enables efficient JK/SR synthesis and reduces product-term usage per function. |
| Programmable pin-keeper | Eliminates need for external pull-up resistors on unused I/Os - cuts BOM cost and prevents floating-induced shoot-through current. |
| Asynchronous reset per register | 20 independent asynchronous reset lines - allows selective initialization of state machine partitions without global reset propagation delay. |
| Synchronous preset | Single common preset line for all 20 registers - simplifies test-mode entry and known-state boot sequences. |
| Power-up reset | Automatic low-state register initialization at VRST (2.0–4.5V) - ensures deterministic startup in motor control and safety-critical logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-15PU | Same logic architecture and timing (15 ns), but in 24-lead PDIP (24P3) package instead of PLCC-28. | Through-hole mounting only; unsuitable for automated SMT assembly or space-constrained layouts. | Select when hand-soldered prototyping or legacy through-hole board repair is required. |
| ATF750CL-15JU | Low-power variant with 1 mA standby current; same 15 ns speed grade but optimized for battery-backed systems. | Higher static power efficiency; trade-off is identical AC performance but reduced dynamic drive strength (IOL = 12 mA vs. 16 mA). | Select for portable or energy-sensitive industrial devices where quiescent current matters more than peak sink capability. |
Compared with ATF750C-15PU and ATF750CL-15JU, the ATF750C-15JI offers surface-mount PLCC packaging with full industrial temperature qualification and standard 16 mA output drive - making it optimal for high-volume SMT production of ruggedized control logic.

FAQ
What is the operating voltage range for ATF750C-15JI?
The ATF750C-15JI operates at 5V ±10%, supporting nominal 5V logic systems with tolerance for supply variation. This matches legacy TTL/CMOS interfaces and eliminates need for voltage translation in retrofit designs. The device's DC characteristics-including VOL ≤ 0.5V at IOL = 16 mA and VOH ≥ 2.4V at IOH = –4.0 mA-are fully specified across this range, ensuring reliable interfacing with standard 5V peripherals.
Does ATF750C-15JI support both D-type and T-type flip-flops?
Yes, the ATF750C-15JI supports individually configurable D- or T-type flip-flops for all 20 registers. This flexibility allows efficient implementation of JK or SR latches using T-type configuration and reduces product-term usage compared to fixed-architecture PLDs. Configuration is handled during JEDEC file generation via Atmel WinCUPL or third-party tools supporting V750 device mnemonics.
What package type is used for ATF750C-15JI?
The ATF750C-15JI uses a 28-lead Plastic J-Leaded Chip Carrier (PLCC-28), designated as package code 28J. It complies with JEDEC MS-018 AB, features a standard pinout, and is RoHS-compliant. Pin 1 is identified by a corner notch; recommended practice connects VCC to pin 1 and GND to pins 8, 15, and 22 for improved signal integrity.
How many product terms does ATF750C-15JI provide?
The ATF750C-15JI provides 171 total product terms, distributed across its 20 sum terms (two per output). A variable format assigns four to eight product terms per sum term, enabling flexible logic decomposition. This density exceeds most 24-pin PLDs and supports complex combinatorial functions-such as full 8-bit address decoding or multi-channel status encoding-within a single device.
Is ATF750C-15JI pin-compatible with older Atmel PLDs?
Yes, the ATF750C-15JI is backward compatible with ATV750B/BL and ATV750/L devices in the same PLCC-28 package. It maintains identical pinout and JEDEC file compatibility in V750B/V750 modes, allowing direct replacement. When recompiled for full ATF750C functionality, it adds T-type flip-flops, pin-clocking, and enhanced feedback-without requiring PCB changes.
