Product details
Overview
CY37064P100-125AXIT from Cypress Semiconductor is a 64-macrocell In-System Reprogrammable (ISR™) Complex Programmable Logic Device (CPLD) in a 100-pin TQFP package, operating at 5V with 125 MHz maximum frequency (tPD = 12.5 ns), supporting PCI-compliant I/O and programmable bus-hold on all pins. It implements four synchronous clocks, product-term clocking, and flexible macrocell configuration for high-speed control logic in embedded interface bridging.
For engineers reviewing the CY37064P100-125AXIT datasheet, CY37064P100-125AXIT pinout, CY37064P100-125AXIT application, or CY37064P100-125AXIT equivalent, this page provides verified architecture details, timing-critical CPLD selection guidance, JTAG-based ISR implementation notes, and migration-ready package compatibility across Ultra37000 density variants.
Technical Context
The CY37064P100-125AXIT belongs to the Ultra37000 family and contains two logic blocks, each with a 72×87 product term array, intelligent product term allocator (0–16 terms per macrocell), and 16 macrocells (mix of I/O and buried). Its Programmable Interconnect Matrix (PIM) delivers 36 global inputs per logic block with no route-dependent delays.
It supports five dedicated inputs-including four clock-capable pins-and features programmable slew rate, asynchronous set/reset, polarity-controlled clocks, and bus-hold on all I/Os. The device uses JTAG (TCK/TMS/TDI/TDO) for ISR and boundary scan, with fixed pinout across 3.3V/5V variants in the same package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 64 total macrocells (distributed across two logic blocks) |
| Maximum Frequency (fMAX) | 125 MHz - guarantees synchronous logic operation up to this clock rate under worst-case conditions |
| Propagation Delay (tPD) | 12.5 ns - fixed, route-independent delay from input to registered output |
| I/O Pins | 69 user I/O pins in 100-pin TQFP - includes 5 dedicated inputs (4 clock-capable) |
| Supply Voltage | 5V VCC with 3.3V/5V-tolerant I/O - VCCO pins configurable for JEDEC 3.3V CMOS or TTL 5V levels |
| Logic Block Clock Sources | Four global synchronous clocks (CLK0–CLK3) + one product-term clock (PTCLK) - each with programmable polarity |
| Bus-Hold | Programmable on all I/Os - eliminates external pull-ups and maintains last state during high-Z, reducing noise in shared-bus systems |
Pinout & Package
Package: 100-pin Thin Quad Flat Package (TQFP), 14 mm × 14 mm, 0.5 mm pitch, RoHS-compliant and lead-free capable.
| Pin/Terminal | Circuit Role | Design Meaning |

| TCK, TMS, TDI, TDO | JTAG Test Access Port | Enable In-System Reprogrammability (ISR) and IEEE 1149.1 boundary scan without requiring device removal |
| CLK0–CLK3 | Dedicated Clock Inputs | Four globally distributed synchronous clocks; each configurable for rising/falling edge triggering per logic block |
| OE0–OE3 | Output Enable Controls | Four product-term-based OE signals - each controls up to eight macrocells, enabling fine-grained tri-state management |
| VCC, GND | Power & Ground | Multiple VCC/GND pairs ensure stable core voltage distribution and low-noise switching performance |
| VCCO | I/O Supply Reference | Separate VCCO pins allow independent 3.3V or 5V I/O rail assignment - critical for mixed-voltage system interfacing |
Key Features
| Feature | Design Value |
|---|---|
| In-System Reprogrammability (ISR™) | JTAG-based reconfiguration without changing pinout or timing - enables field firmware updates and design iteration without PCB respin |
| Intelligent Product Term Allocator | Dynamically assigns 0–16 product terms per macrocell and enables sharing across groups of four macrocells - maximizes logic utilization without speed penalty |
| Flexible Clock Architecture | Four synchronous clocks + one product-term clock, each with polarity control - supports mixed-edge-triggered logic and asynchronous event capture |
| Programmable Slew Rate | Fast/slow edge selection per output - balances EMI compliance (slow) against timing margin (fast) in mixed-signal environments |
| PCI-Compatible I/O | Meets PCI Local Bus electrical and timing requirements - allows direct connection to PCI bus without level-shifting or buffering |
Applications
| PCI Interface Bridge | Legacy Bus Controller |
|---|---|
Use Scenario: Adapting legacy parallel peripherals (e.g., ISA, LPC) to modern PCI slots in industrial backplanes. IC Role / Device Role / Timing Role: CPLD acts as protocol translator and address decoder, managing wait-state insertion and burst-mode handshaking. Use Value: Fixed 12.5 ns tPD ensures deterministic response to PCI FRAME# and IRDY# signals, eliminating timing uncertainty in arbitration cycles. |
Use Scenario: Replacing discrete glue logic in microcontroller-based motor drive boards with aging 8-bit buses. IC Role / Device Role / Timing Role: Implements address decoding, chip select generation, and interrupt multiplexing for multiple sensors and actuators. Use Value: 69 I/Os and four dedicated clocks enable concurrent handling of analog monitoring, PWM sync, and serial command parsing without resource contention. |
| Configurable Power Sequencer | Field-Upgradeable FPGA Configuration Manager |
Use Scenario: Controlling power-up/down sequencing of multi-rail FPGAs and ADCs in medical imaging modules. IC Role / Device Role / Timing Role: State machine-driven sequencer with programmable delays and fault monitoring via GPIO feedback. Use Value: Bus-hold on all I/Os prevents floating control lines during partial power loss, ensuring safe reset propagation across supply domains. |
Use Scenario: Managing dual-image bitstream loading and failover for Xilinx Spartan FPGAs in telecom baseband units. IC Role / Device Role / Timing Role: JTAG master controlling FPGA configuration, CRC validation, and watchdog-triggered fallback. Use Value: ISR capability allows remote update of sequencer logic via same JTAG chain used for FPGA programming - no additional debug interface required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based interface logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY37064P100-100AXI | Same package and macrocell count, but rated for 100 MHz (tPD = 15 ns) - slower timing bin with identical pinout and feature set | Lower fMAX reduces margin for high-speed PCI burst transfers but sufficient for static control logic and slow peripherals | Select when cost sensitivity outweighs need for 125 MHz timing headroom; drop-in replacement with no layout change |
| XC9572XL-10VQG100C | Xilinx CoolRunner-II CPLD: 72 macrocells, 10 ns tPD, 3.3V-only supply, different JTAG instruction set and software toolchain | Lacks 5V-tolerant I/O and PCI-compliance - requires level shifters for legacy bus interfacing; no VCCO flexibility | Choose only if migrating to Xilinx ecosystem and redesigning for 3.3V-only operation; not pin-compatible or ISR-interchangeable |
Compared with CY37064P100-125AXIT, the -100AXI offers identical functionality at reduced speed for cost-sensitive control applications, while the XC9572XL demands full toolchain and voltage architecture changes - making it a platform-level rather than component-level alternative.

FAQ
Is CY37064P100-125AXIT compatible with 3.3V I/O signaling?
Yes - the device supports 3.3V I/O levels when VCCO pins are connected to 3.3V. Outputs meet JEDEC 3.3V CMOS specifications and are 5V-tolerant, allowing safe interfacing with both 3.3V and 5V systems without external level shifters. Core logic remains 5V-powered.
Does this device require external configuration memory?
No - CY37064P100-125AXIT is non-volatile and retains its configuration without external memory. It uses internal EEPROM cells to store logic definitions, enabling instant-on operation after power-up. Configuration is updated exclusively via JTAG ISR.
Can the four dedicated clock inputs be used as general-purpose I/Os?
No - CLK0 through CLK3 are hardwired as dedicated clock inputs and cannot be reassigned as general-purpose I/Os. However, the remaining 65 I/O pins (excluding JTAG and power) are fully configurable as inputs, outputs, or bidirectional with bus-hold enabled.
What development tools support this CPLD?
Cypress Warp v6.0+ and third-party tools including HDL Designer Series and Synplify Pro support the Ultra37000 family. JTAG programming is compatible with Cypress MiniProg, Xilinx Platform Cable USB, and generic IEEE 1149.1 adapters using SVF/JAM STAPL files.
