Product details
Overview
ATF750C-10PI from Atmel is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) in a 24-pin PDIP package, featuring 20 D/T-type flip-flops, 171 product terms, and 7.5 ns pin-to-pin delay at 5V operation. It implements combinatorial and registered logic with programmable pin-keeper circuits and supports both product-term and direct-input clocking for state machines and glue logic in industrial control systems.
For engineers reviewing the ATF750C-10PI datasheet, ATF750C-10PI pinout, ATF750C-10PI application, or ATF750C-10PI equivalent, this device serves as a speed- and density-upgraded replacement for ATV750B/L in legacy PLD designs requiring reprogrammability, low-power standby (1 mA), and full 5V CMOS compatibility without PCB redesign.
Technical Context
The ATF750C-10PI implements a 22-input × 20-output macrocell architecture with dual sum-term per output, variable product-term allocation (4–8 per sum term), and independent feedback paths for all 20 flip-flops. Its logic array supports buried registers, bi-directional I/O, and synchronous preset plus individual asynchronous reset per register.
It uses Atmel's proven electrically-erasable CMOS technology with 20-year data retention, 1000 erase/write cycles, and 2000V ESD protection. Pin-keeper circuits eliminate external pull-ups on unused inputs/I/Os, and power-up reset ensures deterministic state-machine initialization at VCC ≥ 2.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 20 macrocells with 20 sum terms and 171 total product terms - enables complex state machines and multi-function glue logic in single 24-pin IC. |
| Propagation Delay (tPD) | 7.5 ns max (input/feedback to non-registered output) - guarantees fast timing closure in 5V systems up to 95 MHz with external feedback. |
| Operating Voltage | 5V ±5% - compatible with legacy TTL/CMOS 5V buses and eliminates level-shifting in industrial backplanes. |
| Flip-flop Type | Individually configurable D- or T-type per macrocell - supports JK/SR synthesis and mixed-clock-domain logic without external gates. |
| Standby Current | 1 mA typical - enables battery-backed operation in low-power industrial monitoring nodes. |

Pinout & Package
ATF750C-10PI is housed in a 24-lead plastic dual-inline package (PDIP), 0.300" wide (24P3), with standard 0.1" pin pitch and through-hole mounting. Pin 1 is marked by notch or dot; pin 12 is GND, pin 24 is VCC.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLK/IN | Primary clock input or general logic input - selectable as global clock source for product-term or direct-pin clocking of flip-flops. |
| 2–11, 13, 23 | IN | Dedicated logic inputs - provide 12 primary array inputs; all support pin-keeper configuration to prevent floating-induced noise. |
| 14–22 | I/O | Bi-directional I/O pins - each has independent output-enable product term and internal feedback path for registered operation. |
| 12 | GND | Ground reference - must be connected to system ground plane to ensure signal integrity and ESD discharge path. |
| 24 | VCC | +5V supply - decoupling capacitor (0.1 µF ceramic) required within 1 cm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Pin-keeper Circuits | Eliminates need for external pull-up resistors on unused inputs/I/Os - reduces BOM count, board space, and DC power loss in industrial PLC modules. |
| Dual Clocking Modes | Each flip-flop accepts either product-term-derived or direct-pin clock - enables mixed-frequency state machines (e.g., UART + PWM) in one device. |
| Asynchronous Reset per Flip-flop | Independent reset control per macrocell - allows selective clearing of pipeline stages without affecting other logic blocks. |
| Synchronous Preset Line | Single global preset signal initializes all 20 registers to high state - simplifies boot-time configuration of control sequencers. |
| Power-up Reset | Automatic register reset at VCC ≥ 2.0 V - ensures known initial state for safety-critical industrial sequencers without external POR circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-10PU | Same logic architecture and timing, but in 24-pin SOIC (24S) package - 30% smaller footprint, surface-mount only. | Used where board space is constrained and reflow assembly is available; not suitable for through-hole prototyping or repair. | Select when migrating to automated SMT production and thermal management permits SOIC package. |
| ATF750CL-15PU | Low-power variant with 15 ns tPD and 1 µA standby current - trades speed for ultra-low static power. | Preferred for battery-powered portable test gear or remote sensors where 15 ns delay is acceptable. | Choose only if system clock frequency ≤ 55 MHz and standby current < 10 µA is mandatory. |
Compared with ATF750C-10PU and ATF750CL-15PU, the ATF750C-10PI offers optimal balance of speed (7.5 ns), through-hole serviceability, and industrial temperature range (–40°C to +85°C) - making it the default choice for field-replaceable control modules requiring long-term availability and mechanical robustness.

FAQ
What is the maximum operating frequency of the ATF750C-10PI in a registered feedback configuration?
The ATF750C-10PI achieves up to 86 MHz in internal feedback mode (1/(tSF + tCF)), verified at industrial temperature (–40°C to +85°C) and 5V ±5%. This frequency is derived from its 7.5 ns feedback setup time and 5 ns clock-to-feedback delay - enabling high-speed counter and state-machine implementations without external clock dividers. The ATF750C-10PI maintains this performance across its full rated temperature range.
Does the ATF750C-10PI support in-system programming (ISP)?
No, the ATF750C-10PI does not support in-system programming. It requires external parallel programming via a standard JEDEC-compliant programmer (e.g., Data I/O PS-29 or BP Microsystems Model 2000). Programming voltage is 10.5 V applied to pin 8 during programming mode, and the device must be removed from the target board for reprogramming. The ATF750C-10PI retains full functionality after programming and operates normally at 5V.
How many product terms are allocated per macrocell in the ATF750C-10PI?
The ATF750C-10PI provides 171 total product terms distributed across 20 macrocells, with two sum terms per macrocell and variable allocation of 4–8 product terms per sum term. This flexible architecture allows efficient mapping of wide AND-OR logic expressions - for example, a 12-input decode function can consume just one sum term with eight product terms, leaving remaining terms for other functions within the same macrocell. The ATF750C-10PI's allocation is configured during compilation in WinCUPL.
Can the ATF750C-10PI replace an ATV750B-15PC in an existing design?
Yes, the ATF750C-10PI is a direct functional and pin-compatible replacement for the ATV750B-15PC. It uses the same 24-pin PDIP package, identical pinout, and backward-compatible JEDEC file format (V750B mode). The ATF750C-10PI improves upon the ATV750B-15PC with faster 7.5 ns propagation delay (vs. 15 ns), added T-type flip-flop support, and pin-keeper circuits - all without requiring PCB changes or firmware updates.
What is the purpose of the pin-keeper circuit in the ATF750C-10PI, and how is it enabled?
The pin-keeper circuit in the ATF750C-10PI holds unused input or I/O pins at their last driven logic state, preventing floating conditions that cause shoot-through current and EMI. It is enabled during design compilation by selecting the "V750CPPK" device mnemonic in Atmel WinCUPL - which configures dedicated keeper transistors on all 22 logic pins. Once programmed, the ATF750C-10PI eliminates need for external pull-up/pull-down resistors, reducing power and board area. The feature is inactive by default and requires explicit software enable.
