Product details
Overview
ATF750LVC-15JU from Microchip Technology (formerly Atmel) is a high-performance, electrically-erasable complex programmable logic device (CPLD) in a 28-lead PLCC package, delivering 20 flip-flops, 42 array inputs, and 171 product terms with 10 ns pin-to-pin delay at 5V operation. It implements D- or T-type registers, supports individual product-term clocking and direct input pin clocking, and targets glue logic replacement and state machine control in industrial embedded systems.
For engineers reviewing the ATF750LVC-15JU datasheet, ATF750LVC-15JU pinout, ATF750LVC-15JU application, or ATF750LVC-15JU equivalent, key selection criteria include its 3.0–5.5V supply range, 20-year data retention, 1000 erase/write cycles, programmable pin-keeper circuits, and compatibility with ATV750B software tools for legacy PLD migration.
Technical Context
The ATF750LVC-15JU implements a 24-pin-equivalent architecture with 20 sum terms and 20 flip-flops-double the register count of the 22V10 baseline-enabling full-buried state machines without external feedback routing. Its programmable interconnect matrix supports independent clock sources per flip-flop: either dedicated product-term clocks or direct input pin clocking (CLK/IN on Pin 1), allowing mixed-clock-domain logic within one device.
Each of the 10 I/O pins provides bi-directional capability with dedicated output-enable product terms, while all 20 flip-flop outputs feed back into the logic array. The device integrates asynchronous reset per flip-flop, synchronous preset for all registers, and security fuse protection against unauthorized pattern copying.
Key Specifications

Pinout & Package
ATF750LVC-15JU is housed in a 28-lead Plastic J-Leaded Chip Carrier (PLCC) package per JEDEC MS-018 AB, with 22 logic pins (12 inputs, 10 I/O), CLK/IN on Pin 1, VCC on Pins 13 and 14, GND on Pins 8, 15, and 22, and unused pins (1, 8, 15, 22) optionally tied to VCC/GND for improved noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK/IN (Pin 1) | Global clock or logic input | Configurable as primary clock source for input-pin clocking mode or as standard logic input; enables mixed clocking strategies. |
| IN (Pins 2–12) | Array input | 12 dedicated logic inputs feeding the 42-input array; each may drive product terms or serve as asynchronous reset/preset controls. |
| I/O (Pins 16–25) | Bi-directional logic buffer | 10 pins support input, output, or bidirectional operation; each has independent output-enable product term and internal feedback path. |
| VCC (Pins 13, 14) | Power supply | Dual VCC pins reduce IR drop and improve noise margin across wide operating voltage range (3.0–5.5 V). |
| GND (Pins 8, 15, 22) | Ground reference | Three ground pins enhance signal integrity and thermal dissipation in industrial temperature range (−40°C to +85°C). |
Key Features
| Feature | Design Value |
|---|---|
| Programmable pin-keeper circuits | Eliminates need for external pull-up resistors on unused inputs/I/Os, reducing BOM cost and static power consumption by up to 100 µA per pin. |
| Selectable D- or T-type flip-flops | Enables efficient synthesis of JK/SR latches and counters using fewer product terms than fixed-architecture PLDs. |
| Individual product-term clocking | Allows each of 20 registers to operate on unique clock domains-critical for multi-rate protocol bridging (e.g., SPI-to-parallel conversion). |
| Asynchronous reset per flip-flop | Supports selective initialization of functional blocks without global system reset, improving fault recovery granularity in safety-critical logic. |
| Security fuse | Prevents reverse-engineering of programmed logic patterns; once blown, all fuses read as programmed during verification. |
Applications
| Industrial PLC I/O Expansion | Legacy System Glue Logic Replacement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-15JU | Lacks pin-keeper circuits; otherwise identical architecture and timing. | Suitable only when unused inputs are externally terminated; higher static current in floating states. | Select ATF750C-15JU only if pin-keeper functionality is unnecessary and cost reduction is prioritized. |
| XCR3064XL-10VQ44I | 64 macrocells, 3.3 V only, 100-pin VQFP; higher density but incompatible pinout and toolchain. | Requires PCB redesign and Xilinx WebPACK tool migration; not suitable for footprint-constrained retrofits. | Choose XCR3064XL-10VQ44I only for new designs needing >2× logic capacity and 3.3 V-only operation. |
Compared with ATF750C-15JU, the ATF750LVC-15JU adds pin-keeper circuits that reduce external component count and leakage current, while XCR3064XL-10VQ44I offers greater scale at the cost of complete hardware and software requalification.

FAQ
What is the maximum operating frequency of the ATF750LVC-15JU under industrial conditions?
The ATF750LVC-15JU achieves up to 71 MHz maximum frequency with external feedback (1/(tS + tCO)) at 5 V and −40°C to +85°C operation, verified per AC Characteristics Table 15. This performance is sustained across the full industrial temperature range due to its CMOS process and uniform delay architecture-no derating required. The ATF750LVC-15JU delivers deterministic timing critical for closed-loop control in motor drives and PLCs.
Does the ATF750LVC-15JU support in-system programming (ISP)?
No, the ATF750LVC-15JU does not support in-system programming. It requires external parallel programming via a standard PLD programmer compatible with Atmel's ATF750 family (e.g., Data I/O PS-29 or BP Microsystems Model 2000). Programming voltage is −2.0 V to +14.0 V relative to ground, and the security fuse must be programmed last. The ATF750LVC-15JU is electrically erasable but not ISP-capable.
How many I/O pins can be configured as true bi-directional interfaces on the ATF750LVC-15JU?
Exactly 10 I/O pins (Pins 16–25) on the ATF750LVC-15JU support true bi-directional operation with independent output-enable control per pin. Each has a dedicated input path and feedback path into the logic array, enabling simultaneous read/write operations without external direction-control logic. This capability is intrinsic to the ATF750LVC-15JU architecture and confirmed in Pin Configuration Section 3.2.
Is the ATF750LVC-15JU RoHS compliant and lead-free?
Yes, the ATF750LVC-15JU is RoHS compliant and Pb/halide-free per Atmel's Green Package Options specification (Section 23.1). It meets EU Directive 2011/65/EU and is marked with appropriate packaging codes. The PLCC package uses matte tin lead finish and complies with JEDEC J-STD-020 moisture sensitivity level (MSL) 3, verified in the official 1447F datasheet revision.
Can the ATF750LVC-15JU replace a 22V10 in an existing design without modifications?
Yes-the ATF750LVC-15JU is architecturally compatible with the 22V10 and supports identical JEDEC fuse map formats and ATV750B software tools. Its pinout matches the 24-pin DIP/SOIC variants in input/output assignment, though the ATF750LVC-15JU uses a 28-pin PLCC. For 24-pin footprints, use ATF750LVC-15PU (PDIP) or ATF750LVC-15SU (SOIC); the ATF750LVC-15JU requires socket or adapter for direct 22V10 replacement.
