Product details
Overview
CY37064VP44-100AXC from Cypress Semiconductor is a 64-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in a 44-pin TQFP package, operating at 5V with 100 MHz maximum frequency (fMAX) and 6 ns propagation delay (tPD). It features four synchronous clocks, five dedicated inputs (including four clock pins), programmable bus-hold on all I/Os, and JTAG-compliant ISR for field reconfiguration without pinout or timing changes. Used in legacy PCI interface logic, board-level glue logic, and industrial control state machines.
For engineers reviewing the CY37064VP44-100AXC datasheet, CY37064VP44-100AXC pinout, CY37064VP44-100AXC application, or CY37064VP44-100AXC equivalent, key selection criteria include macrocell count, 44-pin TQFP footprint compatibility, 5V/PCI-compliant I/O drive, JTAG-based in-system reprogrammability, and deterministic timing model with no fanout or expander delays.
Technical Context
The CY37064VP44-100AXC implements the Ultra37000 architecture with two logic blocks, each containing a 72×87 product term array, intelligent product term allocator (0–16 terms per macrocell), and 16 macrocells (mix of I/O and buried). All signals route through a fully global Programmable Interconnect Matrix (PIM) with fixed 36-input routing to each logic block and no route-dependent timing penalties.
It supports flexible clocking: four global synchronous clocks (CLK0–CLK3) with polarity control, plus one asynchronous product-term clock (PTCLK); all macrocells support D/T/latch configurations with programmable asynchronous set/reset; I/O cells include polarity control muxes, slew-rate control (fast/slow), and bus-hold enable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 64 total macrocells across two logic blocks - defines maximum combinational and registered logic capacity. |
| Propagation Delay (tPD) | 6 ns - worst-case path delay from input to registered output, enabling 100 MHz system clock operation. |
| I/O Pins | 37 user I/O pins in 44-pin TQFP - includes 5 dedicated inputs (4 clock-capable), supporting mixed signal routing. |
| Supply Voltage | 5.0 V VCC, with 5V or 3.3V I/O tolerance via VCCO configuration - enables direct interfacing to both TTL and JEDEC 3.3V buses. |
| Timing Model | No fanout, expander, PIM, or product-term steering delays - eliminates timing uncertainty during logic density scaling. |
| JTAG Interface | IEEE 1149.1-compliant TDI/TDO/TCK/TMS - enables in-system reprogramming and boundary-scan testing without device removal. |
| Bus-Hold Enable | Per-pin programmable - maintains last valid logic state on high-Z I/Os, eliminating external pull-ups in bus-interface applications. |
Pinout & Package
Package: 44-pin Thin Quad Flat Package (TQFP), 10 mm × 10 mm, 0.8 mm pitch, RoHS-compliant lead-free option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | Dedicated Input / Clock (CLK0–CLK3, GND) | Four configurable clock inputs + one ground reference; CLK pins support polarity inversion and feed global clock network. |
| 6–12, 14–20, 22–28, 30–36, 38–43 | Bi-directional I/O | 37 general-purpose pins with programmable bus-hold, slew rate, polarity, and register/latch/D-mode configuration. |
| 13, 21, 29, 44 | VCC, VCCO, GND, TDO | VCC = 5V core supply; VCCO sets I/O voltage level (5V or 3.3V); TDO = JTAG test data output. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammability (ISR™) | JTAG-based field updates preserve pinout and timing - enables firmware patching and design iteration without PCB respin. |
| Intelligent Product Term Allocator | 0–16 product terms dynamically assigned per macrocell - eliminates manual resource allocation and supports heterogeneous logic depth per output. |
| Programmable Slew Rate | Fast/slow edge selection per output - balances EMI compliance (slow) against timing margin (fast) without external components. |
| PCI-Compliant I/O | Meets PCI Local Bus Specification electrical/timing requirements - allows direct integration into legacy PCI add-in cards and backplanes. |
| Deterministic Timing Architecture | No fanout, expander, or PIM routing delays - simplifies static timing analysis and guarantees timing closure across density upgrades. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based glue logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC9572XL-10VQG44C | 72 macrocells, 3.3V-only supply, 10 ns tPD, no VCCO I/O voltage select - requires external level shifters for 5V bus interfacing. | Limited to 3.3V systems; lacks native PCI compliance and bus-hold - needs external pull-ups for floating bus lines. | Select when migrating to lower-power 3.3V designs and external level translation is acceptable. |
| ATF1504AS-10AU44 | 64 macrocells, 3.3V supply, 10 ns tPD, JTAG ISR, but no dedicated clock pins - clock inputs share I/O resources. | Cannot support four independent synchronous clocks; reduced clock routing flexibility limits multi-clock domain designs. | Select only for cost-sensitive 3.3V applications where single-clock-domain logic suffices. |
Compared with XC9572XL-10VQG44C and ATF1504AS-10AU44, CY37064VP44-100AXC uniquely delivers 5V operation with 3.3V-tolerant I/O, four dedicated clock pins, and PCI-compliant drive strength - making it the only drop-in solution for legacy 5V PCI systems requiring field-upgradable logic.

FAQ
Is CY37064VP44-100AXC compatible with 3.3V I/O buses?
Yes. The device supports 3.3V I/O levels when VCCO pins are connected to 3.3V; outputs meet JEDEC 3.3V CMOS standards and are 5V-tolerant. This allows direct interfacing with 3.3V peripherals while maintaining 5V core operation and full ISR functionality.
Does CY37064VP44-100AXC require external programming hardware?
No. It uses standard IEEE 1149.1 JTAG signals (TDI, TDO, TCK, TMS) for in-system reprogramming. Any JTAG-compliant programmer - including Cypress's MiniProg or third-party tools like Xilinx Impact - can configure or update the device in-circuit without removal.
Can unused I/O pins be left unconnected?
Yes. Programmable bus-hold circuitry maintains the last driven logic state on high-impedance I/Os, eliminating the need for external pull-up or pull-down resistors. This simplifies PCB layout and supports safe prototyping with floating pins.
What is the maximum clock frequency supported by the internal logic?
The device achieves 100 MHz maximum operating frequency (fMAX) under worst-case conditions, verified by its 6 ns propagation delay (tPD) specification. This applies to synchronous logic paths using any of the four global clocks or the product-term clock, with no derating required for macrocell count or routing complexity.
