Product details
Overview
ATF750C-15PI from Atmel is a high-performance, electrically-erasable complex programmable logic device (CPLD) in a 24-pin PDIP package, delivering 7.5 ns pin-to-pin delay at 5V, 20 flip-flops (D/T-configurable), 171 product terms, and programmable pin-keeper circuits. It serves as a superset of the 22V10 architecture for glue logic replacement, state machine implementation, and bus interface control in industrial control systems.
For engineers reviewing the ATF750C-15PI datasheet, ATF750C-15PI pinout, ATF750C-15PI application, or ATF750C-15PI equivalent, this page provides verified timing parameters, confirmed I/O flexibility (10 bi-directional pins), power-up reset behavior, pin-keeper enablement, and direct migration paths from ATV750B/L devices - all critical for legacy PLD upgrades and in-system reprogrammability validation.
Technical Context
The ATF750C-15PI implements a 22-input × 20-output macrocell array with two sum terms per output and variable product term allocation (4–8 per sum term). Its architecture supports independent clocking per flip-flop via either dedicated product terms or direct input pin (Pin 1), enabling mixed-clock-domain logic within a single device.
Each of the 20 registers features individual asynchronous reset, synchronous preset, and configurable D/T-type operation; all feedback paths are fully dedicated, and all 10 I/O pins include programmable pin-keeper circuits to eliminate floating inputs without external pull-ups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay (tPD) | 15 ns max - guarantees deterministic timing for 5V industrial control interfaces requiring ≤66 MHz system clock alignment. |
| Logic Density | 20 flip-flops + 171 product terms - enables full implementation of medium-complexity state machines without external logic. |
| I/O Configuration | 12 dedicated inputs + 10 bi-directional I/Os - supports flexible bus arbitration and data path control in microcontroller peripheral expansion. |
| Power Supply | 5V ±5% - compatible with standard TTL/CMOS logic rails; standby current not specified for -15PI variant but confirmed ≤180 mA active ICC. |
| Operating Temperature | -40°C to +85°C - qualified for industrial environments including motor drives and PLC backplanes. |
| Reprogrammability | 1000 erase/write cycles with 20-year data retention - supports field firmware updates and long-life embedded deployments. |
| ESD Protection | 2000V HBM - ensures robustness during board handling and in-circuit programming. |
Pinout & Package
ATF750C-15PI is housed in a 24-lead plastic dual-inline package (PDIP), 0.300" wide (24P3), with industry-standard pinout compatible with 22V10 and ATV750 families. Pin 1 is CLK/IN; pins 2–12 and 24 are IN; pins 13–22 are I/O; pin 23 is GND; pin 12 is GND; pin 13 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK/IN | Primary clock input or general logic input; selectable per macrocell for direct pin clocking. |
| 2–12, 24 | IN | Dedicated input-only pins; feed directly into programmable logic array with no output capability. |
| 13–22 | I/O | Bi-directional buffers with programmable output enable; each supports pin-keeper activation when tristated. |
| 12, 23 | GND | Ground reference for logic and power; dual GND pins reduce ground bounce in high-speed switching. |
| 13 | VCC | +5V supply; decoupling required adjacent to pin 13 to maintain signal integrity under dynamic loading. |
Key Features
| Feature | Design Value |
|---|---|
| D/T-type flip-flop configurability | Each of 20 registers individually set to D or T mode - enables efficient JK/SR synthesis and reduces product term usage by up to 30% vs fixed-D architectures. |
| Programmable pin-keeper circuits | Active on all 22 logic pins - eliminates need for external pull-up resistors, cuts board space and DC leakage in unused I/O states. |
| Independent clock source per flip-flop | Supports both product-term-derived and direct-pin clocks - allows concurrent operation of multiple clock domains (e.g., UART baud rate + PWM timer) in one CPLD. |
| Power-up reset synchronization | Automatic low-state initialization of all registers at VRST (2.0–4.5V) - ensures deterministic state machine startup without external POR circuitry. |
| Asynchronous reset per register | 20 dedicated reset inputs - permits selective clearing of pipeline stages or error recovery without halting entire logic block. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable logic device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-10PU | 10 ns propagation delay, same 24-pin PDIP package and pinout; higher speed grade with identical logic resources. | Suitable where tighter setup/hold margins are required in high-frequency control loops (e.g., >50 MHz sampling). | Select when system timing budget demands <10 ns tPD and industrial temperature range (-40°C to +85°C) is mandatory. |
| ATV750L-15PU | Non-erasable OTP version; same 15 ns speed grade and 24-pin PDIP, but lacks reprogrammability and pin-keeper circuits. | Used in cost-sensitive, high-volume production where field updates are unnecessary and design is fully frozen. | Choose only for final-production units where JEDEC file locking and zero reprogramming risk outweigh flexibility needs. |
Compared with ATF750C-15PI, the ATF750C-10PU offers faster timing for demanding control applications, while the ATV750L-15PU trades reprogrammability and pin-keeper functionality for lower unit cost in stable, high-volume deployments - making ATF750C-15PI the optimal balance of field upgrade capability, noise immunity, and industrial reliability.

FAQ
What is the maximum operating frequency supported by the ATF750C-15PI?
The ATF750C-15PI supports a maximum external feedback clock frequency of 44 MHz (1/(tSS + tCOS) = 1/(12.5 ns + 10 ns)), and up to 83 MHz with internal feedback. These values are derived from its 15 ns tCOS and 12.5 ns tSS specifications under industrial conditions, ensuring reliable operation in real-time control applications where jitter tolerance is critical. The ATF750C-15PI achieves this without requiring external PLLs or clock conditioners.
Does the ATF750C-15PI support in-system programming?
Yes, the ATF750C-15PI supports in-system programming via standard JEDEC file loading using compatible programmers such as Data I/O PS-3000 or BP Microsystems Series 4. Its electrically-erasable EEPROM-based architecture allows full reconfiguration while soldered on the target board, provided VCC, GND, and programming pins (including VPP if used) meet Atmel's voltage and timing requirements. This capability is intrinsic to the ATF750C-15PI design and does not require additional hardware interfaces.
How does the pin-keeper feature function on the ATF750C-15PI?
The ATF750C-15PI includes programmable pin-keeper circuits on all 22 logic pins. When enabled (via WinCUPL device selection V750CPPK), these circuits retain the last driven logic state (high or low) after an I/O pin transitions to high-impedance, preventing floating inputs that cause shoot-through current or noise coupling. This behavior is implemented internally using weak keeper transistors - no external components are needed. The pin-keeper is disabled by default and must be explicitly activated during fuse map generation for the ATF750C-15PI.
Is the ATF750C-15PI pin-compatible with the 22V10 PLD?
Yes, the ATF750C-15PI is a functional superset of the 22V10 and maintains full pin compatibility in 24-pin packages including PDIP (24P3). Its pin 1 (CLK/IN), pins 2–12/24 (IN), pins 13–22 (I/O), pin 12/23 (GND), and pin 13 (VCC) align exactly with the 22V10 footprint. This allows direct replacement in existing designs, though full utilization of enhanced features (e.g., T-type flip-flops, pin-keepers) requires updated JEDEC files compiled specifically for the ATF750C-15PI.
What programming software is officially supported for the ATF750C-15PI?
Atmel WinCUPL is the officially supported logic compiler for the ATF750C-15PI, providing full access to all device features including D/T flip-flop configuration, pin-keeper enablement, and asynchronous reset mapping. Third-party tools supporting standard V750 JEDEC files (e.g., Lattice ispLEVER Classic, older PALASM versions) can also program the ATF750C-15PI in backward-compatible mode, but will not expose advanced capabilities unless recompiled using WinCUPL's V750CPPK device model. No proprietary drivers or runtime licenses are required to program the ATF750C-15PI.
