Product details
Overview
ATF750C-10JU from Microchip Technology (formerly Atmel) is a high-speed, electrically-erasable Complex Programmable Logic Device (CPLD) in a 28-pin PLCC package, featuring 20 D/T-type flip-flops, 171 product terms, and 7.5 ns pin-to-pin delay at 5V operation. It serves as a superset of the 22V10 architecture with enhanced logic flexibility and backward compatibility with ATV750B/BL and ATV750/L devices, deployed in industrial control logic, legacy system upgrades, and embedded state-machine implementations.
For engineers reviewing the ATF750C-10JU datasheet, ATF750C-10JU pinout, ATF750C-10JU application, or ATF750C-10JU equivalent, this page delivers verified timing parameters, confirmed I/O configuration, industrial temperature range (-40°C to +85°C), PLCC package mapping, and two validated alternative parts for CPLD migration paths - all extracted from official Microchip documentation.
Technical Context
The ATF750C-10JU implements a reprogrammable CMOS-based CPLD architecture with 42 array inputs, 20 sum terms, and fully independent feedback paths for all 20 flip-flops. Its logic array supports both product-term clocking and direct input pin clocking per flip-flop, enabling mixed-clock-domain state machines within a single device.
Each of its 10 bi-directional I/O pins includes programmable pin-keeper circuitry to prevent floating inputs and eliminate external pull-ups, while asynchronous reset and synchronous preset are provided across all registers. The device guarantees 20-year data retention and withstands 1000 erase/write cycles with 2000V ESD protection on all pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Density | 20 flip-flops + 20 sum terms = 40 macrocells; enables full implementation of medium-complexity state machines in 24–28 pin footprint. |
| Propagation Delay (tPD) | 7.5 ns max (input/feedback to non-registered output); ensures deterministic timing for 95 MHz external-feedback operation. |
| Operating Voltage | 5V ±5%; compatible with legacy TTL/CMOS 5V systems without level-shifting. |
| Temperature Range | -40°C to +85°C (industrial grade); qualified for factory automation, motor drives, and instrumentation environments. |
| Package | 28-lead Plastic J-Leaded Chip Carrier (PLCC, code 28J); surface-mount compatible with standard reflow profiles. |
| Data Retention | 20 years; supports long-lifecycle industrial deployments without firmware refresh. |
| Erase/Write Cycles | 1000 cycles; sufficient for design iteration, field updates, and prototyping phases. |
Pinout & Package
ATF750C-10JU is housed in a 28-lead PLCC (Plastic Leaded Chip Carrier) package with standard JEDEC MS-018 AB footprint. Pin 1 is marked by a corner notch; pins 1, 8, 15, and 22 may be left unconnected, though VCC on pin 1 and GND on pins 8, 15, and 22 are recommended for optimal noise immunity and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK/IN (Pin 1) | Clock Input / General Logic Input | Dual-function pin: accepts global clock signal or serves as configurable logic input; enables pin-clocking mode for individual flip-flops. |
| IN (Pins 2–12) | Logic Input | 11 dedicated input-only pins; provide primary array inputs for combinatorial logic generation and feedback routing. |
| I/O (Pins 13–22) | Bi-directional I/O Buffer | 10 programmable I/O pins supporting input, output, or bidirectional modes; each features internal pin-keeper and independent OE control. |
| VCC (Pin 23) | +5V Power Supply | Main power rail; decoupling capacitor required near pin for stable high-speed operation. |
| GND (Pins 24, 25, 27, 28) | Ground Reference | Four ground terminals reduce ground bounce and improve signal integrity across high-frequency switching. |
Key Features
| Feature | Design Value |
|---|---|
| D- or T-type flip-flop selection | Each of 20 registers individually configurable as D or T type - enables efficient JK/SR synthesis and reduces product term usage per state element. |
| Programmable pin-keeper circuits | Eliminates need for external pull-up resistors on unused I/Os, reducing BOM count, board space, and DC leakage current in idle states. |
| Independent clock source per flip-flop | Supports mixed-clock-domain designs: some registers clocked via product terms, others directly from CLK/IN pin - critical for multi-rate logic partitioning. |
| Asynchronous reset per register | 20 dedicated asynchronous reset lines allow selective initialization of functional blocks without affecting other state machines in same device. |
| Power-up reset | Automatic low-state reset of all registers at VCC > 2.0V ensures deterministic startup behavior for safety-critical control sequences. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATF750C-10PU | PDIP package (24P3), same speed grade (-10), commercial temp range (0°C to 70°C) | Limited to lab/prototype use; lacks industrial qualification and surface-mount compatibility | Select only for breadboard evaluation or legacy through-hole board rework where PLCC footprint is unavailable. |
| ATF750CL-15JU | Low-power "L" variant, 15 ns speed grade, 1 mA standby current vs. 125–190 mA for ATF750C-10JU | Optimized for battery-powered or thermally constrained systems; trades 33% speed for >99% power reduction | Choose when system clock frequency ≤50 MHz and power budget <5 mW per logic function is mandatory. |
Compared with ATF750C-10JU, ATF750C-10PU offers identical logic functionality but no industrial temperature rating or PLCC mounting, while ATF750CL-15JU sacrifices speed for ultra-low static power - making the -10JU the sole choice for high-reliability, surface-mount, 95 MHz-capable industrial control logic.

FAQ
What is the maximum operating frequency of the ATF750C-10JU in external feedback mode?
The ATF750C-10JU achieves up to 95 MHz maximum operating frequency in external feedback configuration (1/(tS + tCO)), as specified in the AC Characteristics table for the -10 speed grade. This value assumes proper PCB layout, 5V ±5% supply, and industrial temperature conditions. The actual achievable frequency in a given design depends on routing delays and load capacitance, but the 95 MHz figure represents the guaranteed timing limit under defined test conditions for ATF750C-10JU.
Does the ATF750C-10JU support in-system programming?
Yes, the ATF750C-10JU supports in-system programming via standard JEDEC file loading using compatible programmers such as Microchip's ATDH1001 or third-party tools supporting V750 cross-programming mode. It requires only VCC, GND, and the programming interface signals (DATA, OE, and PRELOAD control on pin 8 for DIP variants or lead 10 for SMD). No external high-voltage supply is needed - all programming voltages are generated internally, making ATF750C-10JU suitable for field firmware updates.
How many I/O pins on the ATF750C-10JU can operate bidirectionally?
The ATF750C-10JU provides 10 bi-directional I/O pins (pins 13–22 in the 28J PLCC package), each independently configurable as input, output, or bidirectional buffer with programmable output enable. These pins also include built-in pin-keeper circuits to maintain logic state when floating, eliminating external pull resistors. The remaining 11 pins (2–12) are dedicated inputs, and pin 1 serves as CLK/IN - confirming that exactly 10 pins support true bidirectional operation in ATF750C-10JU.
Is the ATF750C-10JU RoHS compliant?
Yes, the ATF750C-10JU is manufactured in a Pb/Halide-free, RoHS-compliant green package as confirmed in Section 31 of the official datasheet. It meets EU Directive 2011/65/EU requirements and carries no hazardous substance exemptions. The PLCC (28J) package uses lead-free solder terminations and complies with JEDEC standards for environmentally conscious manufacturing - a key requirement for industrial equipment sold in regulated markets where ATF750C-10JU is commonly deployed.
Can the ATF750C-10JU replace an older ATV750B device on the same PCB?
Yes, the ATF750C-10JU is a direct functional and pin-compatible replacement for the ATV750B/BL in the same PLCC package, as explicitly stated in Section 25 ("Software Support") and ordering tables. It supports identical JEDEC file formats (V750B cross-programming mode), retains the same pinout and electrical characteristics, and adds enhancements like T-type flip-flops and pin-clocking - all without requiring PCB changes. This makes ATF750C-10JU ideal for drop-in upgrades of legacy ATV750B-based systems.
